   Most power plants using oil use bunker c, a fuel
you have to heat to 260 deg f. to get it to flow.     
 Fuel oil is kerosene , a slightly better fuel than
diesel and rarely used in power plants.

    An electric car puts this energy to use at 70%
eff.  A hybrid eff. is only 20 to 50% eff. with the
same energy, re the Prius only getting 37 to 50 mpg
when tested by real people.

     Most production built  ev's get under 150 whrs/
mile. Mine should get under 100 whrs/ mile. On 14kw
that's 140 miles. Try that with a Prius type hybrid.

       No , see above.

   Wind is a good way to go as it only cost 6 cents/
kw. Hemp and other biomass is another good source.

     Less than 10% as most will be charged off peak

      Most power plants run on bunker c, it,s whats
left after taking all the good stuff out of crude oil.
                                                      
I'm building a hybrid now but will try to rarely use
the ice. You do this best by having a ev with 60 to
100 mile range and a small ice dc genorator of about 5
hp/ 1000 lbs. This also eleminates the need for a
second car saving much money. A Prius type hybrid
shutting on and off will have a hard time passing
emissions as it has had.                jerry dycus
