Would be interesting for a crafty person to play around with this at home.. You guys have the luxury of having gas tapped right into all of your homes. NS put their pipeline in and pointed it right towards the USA.
If one could siphon off their home line, and convert their car over it would be pretty slick for a commuter car. May need a compressor setup though, to jam enough in for any sort of range. Maybe arash is interested?? ha
A lot of work and investment to get stations around the country though, so dont drive too far from home.
