Take a look at that baby. This is what Wal-Mart envisions as the future of trucking in America, and natural gas engine manufacturers like Westport Innovations (NASDAQ:WPRT) might want to take note, because this Capstone Turbine (NASDAQ:CPST) powered truck could be one of its biggest threats in the long haul trucking market. Not only does this truck take advantage of cheap natural gas, but its fuel efficiency could potentially blow any previous truck out of the water. 

This may be a concept truck for now, but if Capstone and Peterbilt can prove this to be an economically viable competitor in the long haul trucking market, it could very quickly change the market dynamics. Find out why Capstone partnering with Peterbilt and Wal-Mart could be the prefect way to gain inroads in this huge market and what it could mean for other natural gas engine manufacturers by tuning into the video below.
