That made a fool of the big manufacturers and endangered their patents and repair profits.
My grandfather made his car and tractors on his farm run on wood gas during WWII.

If the government simply said, this is what we want at the tailpipe, do it anyway you see fit, we’d see a lot of innovation.
Instead, the government dictates.
