Hi Bob,
You know, I’m not the smartest kid on the block, but I see
these heavy school buses running around town (Erie, PA)
using…is it propane, butane, natural gas?…is it CH4
or C2H6…I don’t know the chemical formula…but in any
case, they seem to do fine, even 70 miles per hour out
on the Interstate highways. And they’ve been doing it for
years.
So….why can’t we in N. America, build our cars to run
on the same substance? Natural gas is certainly cheap,
propane isn’t too bad cost wise. Why don’t we see this type of vehicle in the mix of hybrids, solar paneled cars, etc. Is there a disadvantage that I don’t see here?
Clear Skies,
Tom Whiting
