ALTERNATIVE FUELS for my 22R yota!....

i saw a website w/a video the other day of a guy that turned his 22R into a hydrogen running engine... anyone seen this? or does anyone have info on changing a gas engine to hydrogen (or something of the nature)

my dads friend/neighbor owns a machine shop and has offered to machine EVERY single part i need if we can find some literature, vids, etc to read up on this !

it looked like it could have been done in a weekend (seemed to be mostly top end parts)

i cant find the site or vid for shit.... why in the hell didnt i save it

I have a 22r and i would love to do something like this. ill be watching this thread
