    Well, none of the technologies are actually 'new', with the possible exception of biodeisel in a picky way. The other major ones being looked at are hydrogen and natural gas. Sorry, but I can't give you any numbers.

    Some people are working on Ultra Capacitors that can hold a lot more energy then a battery, even better then EEstores Ultra Caps.

    What are capacitors in detail ?
    I don't get how two plates that aren't in contact are able to store high voltages.

    as far as efficiency, biodesiel i hear is similar in efficiency to convetional diesel, but just better when it comes to emissions
