主题：奥巴马政府：电池车非零排放，超内燃机 -- 过来看井大

所谓“悍马三的dust to dust energy cost是每英里1,95美元. 而日本动力车的dust to dust 耗能是没英里3.3美元”，你引的文章自己就说了

If reporters had dug a little deeper, they would have clearly seen what the podcast interview exposed: the Hummer H3 looks a whole lot better than the hybrids because it uses "crude old technology that has long ago been paid for," according to Spinella. On the other hand, the hybrids are new and complex, and the cost of the R&D energy required to make the necessary transformation of our cars from oversized, high-emissions gas guzzlers to something new and better has not yet been amortized over any significant period of time.

悍马因为是老旧技术，现阶段基本上没有R&D费用， 而hybrid 这上面有巨大的overhead.
