Free Valve Technology- "Inside Koenigsegg"

[BriK]

Hydrogen and this free valve technology are mutually exclusive-- this impacts the contruction and operation of an internal combustion engine, no matter what fuel is being used. It already seems clear that there's no silver bullet to solving for the 2016 CAFE standards-- engine technology, fuel technology, hybrid technology, aerodynamics, materials, weight, etc. are all being considered.

That said, I'm not deeply knowledgeable about alternative fuels and advancing automotive technologies, and I really don't want to be at the start of, or center of, a politically-charged debate about things for which I have limited knowledge and zero control. (More simply, I don't wanna debate this.)
