Last month, the electric-car industry passed a small but important milestone. There are now more than 100,000 electric cars on America's roads, including those that operate as plug-in hybrids. That's happened in just two and a half years, as electric-vehicle sales have only been tallied independently since the last month of 2010, when a mere 345 were first parked in customer garages.

Despite this milestone, there's plenty of pessimism to go around regarding the adoption rate of the plug-in EV, which have thus far made up only half of 1% of all cars sold in the U.S. this year. My fellow Fool -- and resident Foolish auto expert -- John Rosevear offered a succinct overview of that pessimism a couple of months ago, which I'll sum up as this: There's no charging infrastructure, and the batteries make EVs cost more than is justifiable.

Does that mean EVs are a failure?

From the perspective of the broader auto market, and when compared to the ambitious one-million-EV goal set by President Obama for 2015, EV hype seems destined for the junkyard. However, from a historical perspective, EVs aren't doing so badly at all. In fact, most of the common complaints about EVs are simply short-sighted or downright wrong when viewed through either a historical lens or one with a longer time horizon for the future. Let's take a look now.

Historical perspective on the auto industry
The American auto industry effectively began in 1896 with a 13-vehicle production run at the Duryea Motor Wagon plant (or garage, as the case might well be). Three years later, just before the start of the 20th century, there were roughly 8,000 cars on what passed for American roads -- virtually nothing was paved for vehicle travel. There were 8,000 EVs on the road after eight months of tracking. That's not really fair, though, because there are more than three times as many people in the U.S. as there were at the turn of the 20th century. Adjusted for population growth, there should have been 33,000 EVs on the roads after three years. That happened after 19 months, and we're now approaching three times that number midway through the third year of tracking. In fact, EVs are outperforming hybrids at the same point after adoption as well. Here's what that looks like:

I included battery-only EVs on the chart to prove I wasn't fudging the numbers on EV adoption by using plug-in hybrids -- battery-only EVs surpassed the population-adjusted sales pace of the earliest cars with eight months to go in their third year of tracking. It's also worth pointing out that battery-only EVs have outsold plug-in hybrids by more than 1,000 vehicles for each of the past three months and are on track to reach a cumulative total of roughly 68,000 sales at the end of the year.

Why compare EVs with the earliest cars? The "motor wagons" of the late 1800s faced similar challenges to those often attributed to EVs: minimal supporting infrastructure and a high price tag relative to the dominant (horse-drawn) transportation of the day.

The first gas stations wouldn't even be built until almost a decade after the Duryeas built the first 13 cars in America, and they had no drive-up pumps -- that innovation didn't arrive until 1913. There are already more than 6,000 publicly accessible EV charging stations in the country. This doesn't count interesting infrastructure developments such as Tesla's (NASDAQ: TSLA  ) battery-swap stations or its growing network of "superchargers" scattered across the United States. It's also worth noting that EVs, unlike early internal-combustion vehicles, can get recharged in most owners' garages.

A comparison between the price of cars at the start of the 20th century and the price of EVs today shows another advantage in electricity's favor: the average car in 1900 cost nearly twice the typical household income, while the average base price of the top three EVs on the market today -- Nissan's (NASDAQOTH: NSANY  ) Leaf, Tesla's Model S, and General Motors' (NYSE: GM  ) Chevrolet Volt -- is about 90% of the median national income.

However, EVs have a hurdle that the motor wagons didn't -- the competition is already mechanical, and it has a century-plus head start. The earliest autos simply had to be better than a horse, which is limited by biology to a certain speed and a certain work capacity. A horse doesn't have an R&D budget or an assembly line, and you have to clean up after it, which is pretty gross. Its obsolescence was inevitable. EVs have to beat a competitor that's benefited from tens of billions of dollars in global research and development spending each year for decades , and which is a significant part of a worldwide oil-and-manufacturing infrastructure that creates trillions of dollars in annual revenue.

EVs have to overcome an entrenched culture, just as early motor wagons did -- but today's car culture is far more deeply embedded in the national psyche than horses ever were. There's one automobile on American roads for every 2.3 Americans today, compared with one horse for every 3.5 Americans in 1900. The average person traveled about 340 miles per year in 1900, compared with 16,000 miles per year in cars and airplanes today. Despite facing one of the most entrenched opponents in the history of capitalism, EVs are already outperforming the puttering internal-combustion pioneers in terms of market penetration, price, and infrastructure deployment at a similar point after introduction.

Let's sum some of that up visually:

Autos vs. EVs: a Comparison | Infographics

Hard to hold a charge
Of course, with all of that said, we come back to perhaps the biggest roadblock between EVs and mass adoption: Battery technology just isn't as good as gas. "A full tank of gasoline," according to American Physical Society Fellow Alfred Schlachter, "contains as much energy as 1,000 sticks of dynamite." It's accessible, portable, and (despite protestations over $5 gallons of gas) quite affordable. The New York Times' Green blog quoted IBM battery researcher Winfried Wilcke on the charging-efficiency problem three years ago:

[Wilcke] illustrated the challenge of building a battery with the energy density of gasoline by recounting that it took 47 seconds to put 13.6 gallons of gas in his car when he stopped to fill up on the way to San Francisco. That's delivering power at the rate of 36,000 kilowatts, he said. An electric car would need to pump 6,000 kilowatts to charge its battery in that period.

"The dream that we have today to have exactly the same car charge up in minutes and drive off hundreds of miles cannot happen," Mr. Wilcke said. "Or at least not for 50 years."

Schlachter points out that battery technology is not subject to Moore's Law-like efficiency gains, because "significant improvement in battery capacity can only be made by changing to a different chemistry." Computing hardware has improved on the same substrate by investing in miniaturization technology since the 1960s, but the energy density of a given chemical compound is essentially fixed -- it's only improvements in the surrounding machinery using that compound (whether engines or batteries) that makes more use of the same material.

However, it may not be necessary for EVs to charge in 20 seconds to make them a compelling alternative. Most people simply never drive far enough in a given day to need a quick charge -- 95% of all people tracked in 2009 by the National Household Travel Survey had a commute of less than 40 miles, and the average commute was less than 14 miles. The average total daily driving of urban dwellers was 37 miles, and that of rural drivers was 49 miles. The Nissan Leaf, which is the cheapest of the three best-selling EVs on the market, can drive at least 73 miles on a single charge. Battery quick-swap stations go a long way toward solving the problem of charging delays on the other 5% of those commutes, and the high cost of batteries -- widely seen as the biggest drawback to EV adoption and a roadblock to quick-swap ubiquity -- is not something that will persist forever.

The lithium-ion batteries used in modern EVs have more than doubled in energy density and have declined in price per kilowatt-hour of capacity by a factor of 10 since the early 1990s, when the modern EV movement began to gestate. A McKinsey research paper published last year projects that lithium-ion batteries will continue to decline in price from roughly $600 per kWh today to about $200 per kWh in 2020. Gas prices aren't likely to decline any time soon, so a two-thirds reduction in battery costs would make EVs a better value on balance than internal-combustion vehicles, according to the McKinsey analysis. None of this would account for another battery breakthrough that would make lithium-ion obsolete, and as the commercial impetus to sell EVs continues to gain steam, it only becomes more likely that intensified research will find something better.

Will EVs continue to outperform the original auto pioneers in the face of stiffer competition? I can't say. However, early results are indeed more promising than many pessimistic commentators would you like to believe. Just as autos replaced horses en masse once their technological superiority was undeniable, EVs will have to be objectively better than internal-combustion vehicles to justify widespread adoption. There are bound to be some bumps and bankruptcies along the way. After all, more than 1,000 automakers of all sizes were founded between 1896 and the mid-1920s. How many of them are still around?

Not to mention that all of the energy that's even usable on the surface of the earth is based on some sort of fossil fuel. Even solar power requires fossil fuels to build panels. Solar power is not enough by itself to sustain daily industry.

    #3 Electric vehicles do not save money because the cost of financing them is so much higher than the cost of financing a regular four-cylinder car. A Tesla model S is $15,000 more than an Audi A6 similarly equipped. The starting price of a Model S is almost $30,000 more than a Dodge Charger with a V6.

    This article makes some erroneous comparisons and a lot of assumptions. There are 3 things which prevent electric cars from replacing gas powered cars.

    1. Range

    2. Recharge time

    3. Cost

    Range needs to be closer to 400 miles to compare to a gas powered car. Teslas get around 230 miles but they cost $70,000 which is far out of the reach of average Americans.

    Recharge time is overnight on a regular plug in for all electric vehicles currently. Installing a 240 charging station cuts that down to 3-4 hours and costs $2,000+ depending on installation. Once again if you drive to the next city over you'll be stuck waiting for a recharge, might as well watch a movie. A 480 volt charging station cuts the charge time to 30 minutes which isn't bad, just be ready to pay $10,000 for it.

    As for cost... currently these vehicles are heavily subsidized and they still cost too much to buy. Leases are an expensive way to go so I always hesitate even on the subsidized ones.

    In short, the electric cars are not ready for the mass market yet. Eventually, just not currently.

    Tesla is working on a more affordable car, so it will be interesting to see how that one shapes up. If they can get the price below 30K, and if it has decent range, it could sell quite a bit. The range issue isn't as big a deal as most people think ... unless they live in rural areas and need to travel very far distances.

    The infrastructure comparison is misleading. EV charge points that most people will use are already easily accessible in their homes. You don't need an external infrastructure most of the time.

    Additionally, the energy density and transfer rate of gasoline is equally misleading since the poor efficiency of internal combustion engines means that about 80% or more of that potential energy is simply lost in use, while an electric motor may only lose 10% or so.

    As for the "rich liberal fools" who buy Tesla's, they use them for all their driving, and with access to superchargers and soon to come swapping stations it will become even easier to do so. The Tesla Gen3 sedan coming in 2016 will bring the technology to the masses at a lower price point in the $30K range. When you take into account the lower "fueling" costs then ownership costs are more in line with a $20K ICE vehicle, running on American electrons to boot. Solar charged if you wish as well. This is the future, embrace it.

    The article lacks sufficient historical research. By the start of the 20th century there were nearly 100,000 automobiles in the US; 40 percent were steam powered, 38 percent were electric, and only 22 percent were gasoline powered. In terms of market share, electric cars peaked in 1912.

    Tesla's newest proposal - swappable batteries - is also nothing new. The Hartford Electric Light Company created such a system in place for electric trucks that operated from 1910 until 1924.

    We've been down this road before. Yes, technology has improved, but some factors have remained for more than 100 years - batteries are very expensive, electric vehicles don't have the range of comparable gas powered vehicles, and batteries take far too long to recharge. These were the reasons why gas powered vehicles ultimately buried electric cars a century ago, and remain why electric cars will not gain significant market share now. Unless some radical new electrical storage technology comes along, electric cars will be nothing more than a fad.

    "In short, the electric cars are not ready for the mass market yet. Eventually, just not currently."

    Eventually is 3.5 years from now, when Tesla starts rolling the Gen III cars off the production line. From an investment point of view, that's equivalent to today since it quite easy to transfer existing electric technology from the S car, which is real and is rolling on the streets, to the smaller Gen III car, and provide as good or better economics than shown below.

    "A full tank of gasoline," according to American Physical Society Fellow Alfred Schlachter, "contains as much energy as 1,000 sticks of dynamite."

    yes, that's true when its in gas form, not liquid. a typical 20 gallon tank holds 674 kilowatt hours of energy, using Dept of Transportation measure of 33.7 kilowatt hours per gallon of gas Since the average ICE is at best 25% efficient, that leaves 168 kilowatt hours of energy to use to move the car forward. The rest of your money ends up in the atmosphere as various poison gases. The Tesla S is rated 95mpg. Comparable cars are approx 22 to 25 mpg.

    20 gallons at $4.35 a gallon here in So. Calif at 25 mpg will cost a consumer $0.174 per mile. You can charge your Tesla at my home at $0.10 per kilowatt hour and go 265 miles on an 85 kilowatt hour charge, which is $0.032 per mile. Do the math.

    If you use San Diego Gas and Electric rates (per their website) to charge your Tesla S at $0.14 per kilowatt hour, then your per mile rate is 14/10 x 0.032 = $0.0448. (Still more than 300% cheaper than gasoline).

    "There's no charging infrastructure, and the batteries make EVs cost more than is justifiable." That author is completely wrong. Every home in the United States has electricity and can plug and charge the EV overnight while a person sleeps. Over

    90% of the trips we take in a car require only 100 miles of range or less in a given day.

    So EV ranges are already sufficient. So public infrastructure for EV's is only needed for travelers, and already, hotels, motels and restaurants are installing their own charging stations to cater to EV car drivers on their vacations. Tesla is already building public infrastructure for charging their cars and there are several public companies doing the same in a more generic manner. EV infrastructure is far less expensive or complicated to install than gas based infrastructure, since its only electricity outlets.

    Batteries are expensive, and their cost per car is declining. However, the battery is already shown above to vastly less expensive than gasoline which means the overall cost of owning an electric car is vastly less expensive than owning a gasoline car, and total cost of ownership is the only reliable measure when deciding whether to buy an EV or an ICE vehicle.

    Like I said, the Tesla S is rated 95mpg and the comparable cars in its class are 300-400% less efficient. In addition the Tesla S has far less maintenance costs over its lifetime because it simply has far fewer moving parts than an ICE car.

    Get used to it. EV's are better and ICE cars are dinosaurs. By 2025 all new vehicles sold in the world will be EV's.

    EVs, on the other hand are about 90% efficient in turning battery power into kinetic energy.

    Now, do EVs need the ~400 mile range of gasmobiles to be "good enough"? I think not.

    The "good enough threshold" for popular adoption is around 180 miles. With rapid chargers, ~ 20 minute, 90% charging along the highways one can drive 500 miles with two modest length stops.

    People driving gasmobiles are likely to stop twice as well. Once to refill and once to eat/pee/walk the dog. With an EV you can charge and eat/pee at the same time.

    We reach the ~180 mile range threshold and few people would avoid EVs because they can't drive 400 miles non-stop in a day.

    Especially when they costs about 1/4th as much per mile to drive.

    An EV charging with 100% coal-electricity would be slightly more CO2 'dirty' than an efficient ICEV.

    The US grid is about 19% nuclear and 13% renewable (including hydro). So EVs are right now much less CO2 intensive than ICEs.

    (Coal was down to 35% in 2012.)

    If you're an average 13,000 annual mileage drive you could put about $9,000 worth of solar panels on your roof. Your gas savings would pay the system off in about five years. And then you'd have 20, 30, 40 or more years of cost free charging.

    $9,000 / 30 years / 12 months = $25 per month.

    That's some seriously cheap driving.

    The opposite is almost certain to happen.

    Onshore wind in the US tends to blow harder at night which happens to be when demand is lower.

    EVs will mostly get charged while parked overnight.

    More EVs on the grid will create a new market for onshore wind. Better selling price, more profits, more investment, more turbines installed.

    Bringing EVs on line will almost certainly cause wind capacity to increase. And that will mean that there will be more inexpensive wind available during the day for our other uses and will lower our electricity costs.


    BTW, we have adequate capacity and transmission during offpeak hours, right now, to charge about 75% of all US cars and light trucks if they suddenly turned into EVs.

    There is a huge difference between off-peak and peak hour demand levels. We have to build our grid to cover peak demand which means that a lot capacity stays offline much of the day/year.

    Scuttlebutt is that we're likely already down to the $200 per kWh range.

    "On Wednesday this week at the annual conference of Canada’s Automotive Parts Manufacturers’ association, GM’s head of global R&D let his guard down slightly in saying prototype electric cars now being evaluated on U.S. test tracks have triple the energy density of a Chevrolet Volt, and close to double that of a Tesla Model S.

    A Volt has about 140 watt-hours per kilogram energy density in its LG Chem lithium-ion T-shaped battery pack. Tesla’s “skateboard” chassis now uses Panasonic cells that reportedly deliver as much as 240 Wh/kg, and Tesla CEO Elon Musk said to expect more.

    And so has GM in so many words.

    “Today there are prototypes out there with 400 Watt-hours per kilogram,” said Dr. J. Gary Smyth, executive director of Global Research and Development, General Motors Company.

    Smyth added the mystery batteries will cost much less than batteries in today’s electric cars and they’ll have a “big impact” on the auto industry and “it completely changes the equation” on cost, range, and vehicle packaging."

    GM owns a piece of Envia Systems who claim to have a 400 Wh/kg, $125/kWh battery that retains 91% capacity after 300 cycles.

    And here's an interesting read concerning how cheap Tesla batteries may already be...

    You can buy a Nissan LEAF for $21,300 (including the federal subsidy). That's less than a stripped down Camry. (You can buy an econobox for less, but it's an econobox.)

My other battery-powered appliances don't work well in the winter; why would I expect a battery-powered car to work well.

    My current solution is a diesel-fueled Ford F-350 monster. doesn't get great mileage, but it's not bad either. I get about 14 mpg when towing. Even if it got 6mpg, It would matter to me because I only put a few thousand miles per year on the truck. It serves all my needs.

    Why would I go buy a $30,000 to $40,000 EV to drive back and forth to work when I need something else anyways? If I'm worried about efficiency, I'd go buy a 1992 Honda Civic.

    You're a one-vehicle family? You drive very few miles per year? You pull a bunch of stuff?

    You aren't a potential EV owner, given the choices right now. (I'm not either. I really need 4wd.)

    What would likely work well for you, when they come to market, would be a plug-in hybrid pickup. Do your daily short distance commute on electricity and the long runs on fuel.

    Well, you might want something nicer than a 1992 Honda Civic. Something with air bags, that sort of thing.

    Again, the Nissan LEAF is selling for $21,300. Not $30k to $40k. If your state also gives subsidies your cost could be as little as $15,300.

    The only problem with EVs and hot climates that I'm familiar with is a loss of range if the batteries are recharged too often using a rapid charger on hot days. That's for EVs with air-cooled batteries.

    A liquid cooled system like the Volt uses could solve that problem. And the heat pump normally used to cool the passenger cabin could cool the batteries during charging. The EV would already be hooked to the grid. Just flood the pack with a bunch of chilled air.

    The cold weather and EV problem can be greatly eliminated by pre-heating the EV with grid power. This can be done remotely via cell phone/computer or by setting a "warm me up" time.

    Once in use batteries give off heat and would keep themselves warm. That heat can also be used to help heat passengers.

    The new heat pump system that Nissan is using greatly cuts down on power drain/range loss.

    Many of us who have lived in cold places are familiar with plugging our ICEVs in on cold nights so they will start in the morning. Block heaters or light bulbs under the hood.

    In the coldest of cold places there might be a need for outlets at work/school parking lots for drive home pre-heating.

    Mercedes did extensive of their EV prototype in very cold conditions and it did fine.

    Just have to think about the battery pack as a cranky old person who needs to be looked after. Warm them up when it's cold. Cool them down when it's hot.

    Remember, Henry's first Model T did not have windshield wipers, an electric starter, a fuel pump or lights. Those things were all possible, it just took a few years to get them in place.

    How long does the EV battery last?

    We don't actually know. We know what the warranties are. Nissan gives owners 8 years, 100,000 miles on workmanship and 6 years, 60,000 miles " against capacity loss below nine bars of capacity as shown on the vehicle’s battery capacity level gauge ". We're all pretty well acquainted with the fact that gasmobiles generally last a lot longer than their warranties. We'll have to wait and see.

    How many batteries per life of vehicle?

    I'd guess two. One set per 100,000 miles. Or maybe only one. People might decide to trade in their car after 100k and buy a new one. There are a lot of people whose budgets would like a used EV that could drive 50 miles per charge.

    How well do the other EV parts hold up?

    The electric motors should hold up very well. This is old tech. Putting a 300,000 mile motor in an EV wouldn't be expensive.

    Brakes will last at least twice as long. Lots of time the mechanical brakes aren't used, regenerative braking slows/stops the car and charges the batteries at the same time.

    Of course there's no fuel pump, water pump, oxygen sensor, spark plugs, air filter, belts, catalytic converter, radiator, ....

    Is the price of the home charging system included in your EV costs?

    EVs have built in chargers. They're good enough for most people's charging. If you drive a lot of miles per day then you might want to purchase a faster charger.

    That could cost up to $2k including installation. But if you're a high mileage driver then you'd be saving well more than that in one year of EV driving. I was just in an exchange with a guy who is spending between $5k and $6k a year for fuel and maintenance. He could drive a LEAF since he can plug in at work and save over $4k per year.

    How many mechanics can service EVs?

    Any dealer that sells EVs is going to have techs who can take care of battery/motor/computer problems. The other parts of the car (steering, window operators, AC, etc.) are like any other car.

    If my EV breaks down where will AAA take it?

    Most insurance companies tow/haul to where it can be fixed. That would probably be the nearest dealer.

    Bottom of this page is where I found the battery warranty stuff. I'd guess the non-EV parts are covered like any other Nissan.

    Apparently there's a Prius hybrid that's put 300,000 on its battery.

    BYD, the Chinese EV maker, has had a number of their EVs in taxi fleets for a couple of years. They are getting 'rapid recharged' daily, perhaps more than once. Their highest mileage EV has now gone over 250,000 miles on its original battery.

    BYD states that the battery will retain 75% of its original capacity after 1,000,000 kilometers (621,000 miles). They are using an iron-phosphate battery.

    Honda is using Toshiba SCiB lithium-ion batteries in their FiT EV. That is supposedly a 4,000 cycle battery. In a 100 mile range EV one should be able to drive 400,000 miles before the range dropped below 80% of original.

    Of course it will be a few years before we know how much, if any, of that is true. But I think what we can count on is that replacing a battery pack after a few years is going to be cheaper than replacing an engine in a ICEV. Battery prices seem to be falling fast.

    There's a need for standby power, regardless of the generation source. Supply and demand constantly rise and fall.

    Using spinning reserve is one way of dealing with changes, be they from clouds going in front of the Sun or any other change in supply like a coal turbine failure. Hydro is better since you can let the turbine spin at speed without load and use very little water. Even better are the battery and flywheel systems we're moving to.

    Nothing works all the time. Nuclear plants have about a 90% capacity, coal plants about a 85% capacity. We have to design our grids to deal with very large plants going down, sometimes without warning.

    Wind and solar are much easier to manage. They don't fail catastrophically like thermal plants do. And they are more distributed which means that they ramp up and down more evenly rather than abruptly.

    We've got quite a bit of dispatchable generation on our grids. Gas and hydro are dispatchable. We've got 21 GW of pump-up hydro and CAES storage that we built in order to use nuclear on our grids.

    We've got quite a bit of ability to operate around the variability of wind and solar. Our grids could be converted to about 40% wind and solar before we'd need more storage or dispatchable generation.

    Coal certainly is going away. We're down from around 55% coal to 35% in 2012. And we've got somewhere between 100 and 200 coal plants targeted for closure. Coal, as a large investment bank stated, is a dead man walking.

    Natural gas will linger on for a while. Largely because it is dispatchable. But we're seeing battery technology coming on line that should start replacing some of our gas peaker plants.

    Rates will fall. Wind is decreasing the cost of electricity already in places like Texas which have a lot of wind capacity installed.

    We need more solar before it starts to cut electricity prices. Germany is way ahead of us and in 2012 solar cut the wholesale price of electricity by over $5 billion. Solar eliminates purchasing very expensive peaker power.

    One thing you may not realize. Coal is our most expensive electricity generator. Not based on what we pay at the meter. But what we pay in tax dollars and health insurance premiums due to the health damage from coal pollution. Coal-electricity is close to twice as expensive as solar.

    (A wise investor recognizes all the costs.)

    The boom in natural gas is pretty much over. We've found that many of the wells drop very significantly in output about a year after they come on line. That means that we have to drill new wells or re-frack the old ones. That's driving up the cost of NG. It's more than doubled off its bottom of a year or so back.

    Wind and solar keep on getting cheaper. For a while our grid will use wind and solar when they are available and fill in with natural gas. As time goes on we'll replace NG with storage. We've got battery storage that's only a little higher than NG generation and battery prices will almost certainly drop.

    With the Tesla model you would exchange your own battery for a "rental" at some point in a long trips. You would be required/expected/whatever to return and swap in your own battery at the end of the trip.

    You'd just be renting a different battery during long trips and leaving yours "at home".

    I suspect battery swaps are not going to be a big part of EV driving. The Tesla model has owners paying $80 for a 1.5 minute swap in order to not have to spend 20 minutes getting a free charge.

    Not many of us would do that, especially considering that we could eat/pee/check our messages while our car was charging.


    If batteries did not improve enough to reach the "threshold of acceptability", about 180 miles, then swapping would be a very good way to solve the long distance travel problem.

    Better Place's swapping system was even faster than Tesla's, 73 seconds vs. 90 seconds.

    To make battery swapping work the best approach would probably be to greatly standardize EV batteries. At least only a few different sizes/shapes. Keep inventory levels low at exchange stations.

    Then, lease batteries rather than selling them. That way there would be no concern about losing control of your battery and ending up with an inferior one.

    You might pay a 'mileage fee' for the distance you drive on a leased battery which you charge on your own and an 'exchange fee' when you do a quick swap.

    Leasing would make the initial purchase price of EVs lower. As long as the cost worked out to about the same cost as owning over the life of the vehicle there should be no complaint.

    But I think we'll see "200 mile" EVs that can be recharged to 90% capacity in less than 20 minutes soon. In less than three years is my best guess.

    Back in the very early 1980s I switched my business from ledger books, paper tape adding machines, and typewriters to Apple II computers.

    Around me other business owners were saying things like "I'd never trust a computer", "They're too expensive", "Computers will never replace paper records". And look at us now.

    Yes, EVs are still expensive. Without the federal subsidy they wouldn't pay for themselves.

    And yes, ranges are low. They have enough range for about a third of all drivers but not 100%.

    The Apple II was incredibly limited and expensive 'back then'. Technology marched forward.

    I'd like to see your vehicle find it's way home after you've been out for dinner and drinks! Or get it's fuel from your lawn! Besides, a horse will keep you warm for days! Let's see your vehicle do that without refills.

    Mr. Wallace:

    You have punctured your own arguments for EVs. They require SUBSIDIES!! The Germans are moving away from Solar and WInd because they are just too damned expensive to support. Guess what they are moving to? That's right, COAL!!!

    As for fossil fuels going away, that remains doubtful. There is just too much demand for them. They are still by far the cheapest form of energy known to Man and you can argue for their demise all you want, they are not going away in your or my lifetime!

    What this article also doesn't mention is that all batteries lose their charge-holding capability in cold weather faster than in warm weather. So, for colder climes, you'll be buying batteries at a faster rate. Maybe in a few decades from now, but not now.

    We are in the MF community because we are, presumably, smart investors. Many of these very impassioned comments are tinged with political bias, one way or another. The question for us is not whether EVs are good or bad or the inevitable future or not but only - would you invest in Tesla stock? All you folks out there who are so encouraged about the future of EVs, have you invested in ANY of the companies in that ecosystem? If not, well stop boring me. BTW, I have not done so.

    I have been very happy with my Prius hybrid since 2005. A plug-in hybrid could be the best of both worlds, with a broad selection of range/cost for many different driving patterns. I am considering one for my next vehicle. My commute is only 2 miles, but I often take MUCH longer trips for both business and pleasure. A lengthy recharge would be, for me, a deal-stopper.

    One factor that often gets missed in the analysis of EVs is the inefficiency of the electric grid.

    Depending on how far one is from the generation, losses can exceed 50%, on top of the relatively low efficiency of most fossil fuel plants.

    Fossil fuels are only "cheap" because so many of the costs are externalized onto the public- disease caused by toxic pollution in the air and water, contaminated water from pipeline spills and fracking, mercury spread over the land from burning coal, wasting millions of gallons of water fracking each well, etc. The biggest externalization would be global warming.

    Put the true costs into the price for fossil fuels and they make solar and wind cheap by comparison.

    Solar is getting cheaper and more capable all the time, and some day soon we'll all be able to have little power plants on our rooftops. As batteries improve, we'll be set.

    I just drove my cousin's Tesla S and all I can say is wow, what a car. Crazy acceleration, super quiet, refined, tons of room. It leaves a BMW M5 in the dust. He loves it and I can see why. The giant iPad on the dashboard works very well for all controls, interior is classy, seats super comfortable and adjustable. I can't wait to see what they can do with the lower cost model. I didn't think Tesla would pull it off, but they have.

    Aesop Institute is an elaborate fraud, operated by Mark Goldes.

    Mark Goldes, starting in the mid-seventies, engaged for several years in the pretense that his company SunWind Ltd was developing a nearly production-ready, road-worthy, wind-powered "windmobile," based on the windmobile invented by James Amick; and that therefore SunWind would be a wonderful investment opportunity.

    After SunWind "dried up" in 1983, Goldes embarked on the long-running pretense that his company Room Temperature Superconductors Inc was developing room-temperature superconductors; and that therefore Room Temperature Superconductors Inc would be a wonderful investment opportunity. He continues the pretense that the company developed something useful, even to this day.

    And then Goldes embarked on the pretense that his company Magnetic Power Inc was developing "NO FUEL ENGINES" based on "Virtual Photon Flux;" and then, on the pretense that MPI was developing horn-powered "NO FUEL ENGINES" based on the resonance of magnetized tuning-rods; and then, on the pretense that his company Chava Energy was developing water-fueled engines based on "collapsing hydrogen orbitals;" and then, on the pretense that he was developing ambient-heat-powered "NO FUEL ENGINES." Goldes has even claimed that Jacob T. Wainwright already patented an ambient-heat-powered engine 100 years ago - even though Wainwright himself certainly never made any such claim, at all. Wainwright's only patent for a turbine or engine was not for any ambient-heat-powered engine, but for a pressurized-gaseous-fluid-powered engine. The innovation of the patent was the use of water to reduce speed - not any use of ambient heat.

    Goldes' forty-year career of "revolutionary invention" pretense has nothing to do with science, but only with pseudoscience and pseudophysics - his lifelong stock-in-trade.

    I have spent months investigating the career of Mark Goldes, Aesop Institute's Perpetual Scam Machine.

    1976: Goldes seeks investors with fraudulent claims to have developed a nearly production-ready, road-worthy, wind-propelled, wind-rechargeable "windmobile" that could reach 60 mph. Goldes has never developed any roadworthy windmobile.

    1998: Goldes fools the gullible US Air Force with his "room temperature superconductor" scam, receiving over four hundred thousand dollars in "Innovative Research" grants. Goldes has never produced any superconductor.

    2005: Goldes seeks investors with fraudulent claims that his company, MPI, is developing "Magnetic Power Modules" based on "Virtual Photon Flux."

    2008: Goldes seeks investors with fraudulent claims that "MPI is also developing breakthrough magnetic energy technologies including POWERGENIE (Power Generation of Electricity by Nondestructive Interference of Energy)." The basic idea of POWERGENIE is to generate electricity from sound energy, by blowing a horn at a magnetized tuning rod. Goldes claims to have "run an electric car for more than 4,800 miles with no need to plug-in." According to Goldes, "[MPI] Revenues from licenses and Joint Ventures are conservatively projected to exceed $1 billion annually by 2012."

    2009: Goldes seeks investors with fraudulent claims that his latest scamporation, Chava Energy, "has been developing enhanced theoretical and practical paths that lead towards commercialization of energy conversion systems that utilize hydrinos." He now claims to be "developing a Self Powered Internal Combustion Engine – SPICE(tm) powered by hydrinos." ("Hydrinos" are pure fiction and do not exist.)

    "For over 20 years Mark Goldes has claimed his company MPI has been developing machines that generate energy for free. In over 20 years his company has not presented one shred of evidence that they can build such machines...

    "For the past five years Mark Goldes has been promising generators 'next year.' He has never delivered. Like 'Alice in Wonderland' there will always be jam tomorrow, but never jam today."

    - Penny Gruber, December 2008

    - Gruber's comment was written almost five years ago - but it's just as true today - except that MPI, Goldes' corporation that he claimed would bring in one billion dollars in revenue from his horn-powered generator in 2012, is now defunct, having never produced any "Magnetic Power Modules" - just as his company called "Room Temperature Superconductors Inc" is also now defunct, having never produced any "room temperature superconductors." Evidently there's a limit to how many years in a row the same company can claim it will finally have something to demonstrate "next year." Now Goldes has a new scamporation, Chava Energy.

    Goldes' current favorite scam is an engine that would run on ambient heat - which is clearly ruled out by the Second Law of Thermodynamics. But of course, the laws of physics always make an exception for the scams of Mark Goldes.

    Mark Goldes is a textbook-ready example of a highly talented con artist who clearly takes pleasure in fooling people with his ludicrous claims, artfully peppered with pseudoscientific rubbish.

    Make no mistake: Mark Goldes' scamtastic Aesop Institute is a ZERO-STAR nonprofit.

    Let's look at just one example of Goldes' offerings in "revolutionary new technology:"

    Most Ludicrous Scamvention: Mark Goldes' "POWERGENIE"

    One of the most laughable of Mark Goldes' many invention scams is his "POWERGENIE" horn-powered generator. The brilliant idea of this revolutionary breakthrough is to blow a horn at a magnetized tuning rod, designed to resonate at the frequency of the horn, and then collect the electromotive energy produced by the vibrations of the rod.

    I'm not making this up.

    POWERGENIE tuning rod engine explained - from the patent:

    [The device incorporates] "an energy transfer and multiplier element being constructed of a ferromagnetic substance... having a natural resonance, due to a physical structure whose dimensions are directly proportional to the wavelength of the resonance frequency..."

    "In this resonant condition, the rod material functions as a tuned waveguide, or longitudinal resonator, for acoustic energy."

    "Ferrite rod 800 is driven to acoustic resonance at the second harmonic of its fundamental resonant frequency by acoustic horn 811, resulting in acoustic wave 816 within the rod having two nodal points... Bias magnet 801 produces magnetic flux 802 extending axially through both nodal points developed within rod 800... The sum electromotive force of coils 820 and 821 develops electrical current and power in resistive load 830."

    - But the patent doesn't tell us who is going to volunteer blow the horn at the rod all day. Perhaps it will come with an elephant.

    Goldes claimed in 2008 that this wonderful triumph of human genius would bring his company, Magnetic Power Inc, one billion dollars in annual revenue by 2012. Magnetic Power Inc is now defunct, having never produced any "Magnetic Power Modules" - just as his company called "Room Temperature Superconductors Inc" is also now defunct, having never produced any "room temperature superconductors."
