It's going to take a scientific breakthrough to truly get these vehicles to mass market. Battery powered or hydrogen fueled, which will it be?
If true, the little-noticed concession is a serious setback for GM and a large swath of the automobile industry. It would also represent a victory for actors from ExxonMobil to Tesla Motors that have placed bets against the ability of scientists to create a breakthrough automobile battery. Exxon and other oil super-majors say electric cars will grab only a slender market niche for at least another quarter century and probably longer, and Tesla’s Elon Musk is gambling that he can keep using off-the-shelf batteries to power his otherwise technologically dazzling vehicles.
