I know nothing about motor vehicles, could you tell me if truck engines or automobile engines for that matter, can be easily adapted to liquified natural gas? Would it be necessary to make changes in the engines? I have heard T. Boone Pickens on the radio talking about putting the country’s trucks on LNG.

I’m still poking around; if I find something more concrete, I’ll copy you on it.
