- Actually, a switch to hydrogen would be much easier that electrics.
- first, piston engines will require new fuel systems and heads, rotories only
- a new fuel system. This is a minimal tooling and desgin change when compared
- to eletrics, which change the entire weight balence of the car, requiring
- changes to structure, suspension, drive drain, controls, new ways of operating
- all the accesories that run on engine vacume (power breaks, power steering, etc)
- among other things. actually to make hydrogen work will be best option.
- the major problem with hydrogen is storage and transport. metal hydride storage,
- where the H2 is dispressed in the metal's atom lattice until it is realeased by
- heat, is as I remember a bit heavy, but does work. The goal is to get a fuel
- that has the same energy to weight ratio as gasoline, and as of today nothing
- comes close. (except for prehaps some other HC fuels, but they produce other
- emissons that there is no way at present to control)
