  •  why that way? (0+ / 0-)

    Doesn't it make more sense to just fuel internal combustion cars directly with biodiesel, rather than losing energy converting to electricity, and having to build an entirely new infrastructure?  What advantage is there in doing it your way?

    Liquid hydrocarbon fuels (gasoline, diesel, alcohol, etc) solve a LOT of problems, and there's already infrastructure in place for them.

      it's less efficient to power a vehicle directly with biodiesel than it is to power it with electricity. Even with current technology, electric vehicles have a lower operating cost per mile (1.5 to 4 cents per mile) than gasoline powered vehicles (roughly 15 to 25 cents per mile).

      I'm an engineer working on an Electric Vehicle project with several other engineers locally. We've amassed some pretty good data on the subject.

      The biggest problem with EVs has always been how much range you can get on Lithium Ion or Lead Acid batteries. The cost of the electricity is relatively trivial.

      A regime is at it's most dangerous when it believes it's own propaganda...but that is also when it is most vulnerable.

        Seems to me that it would be best use of biofuels to supplant costly diesel fuel stocks, especially for commercial users such as locomotives, trucking, and off highway equipment, and at somepoint JetA.

        Fossil fuel generation of electricity for recharging of electric vehicles, while not ideal, isn't going to have much of an adverse impact for quite a few years, or at least until electric vehicles become commonplace.

        Better it would be to begin incorporating solar PV, wind and additional nuclear into the grid and use offpeak capacity of the powerplants for recharging vehicles.
