    I don't know about this kit... but for about $10K you can convert your car to 100% electric... with that you'll get about 100 miles on a charge, and a charge will cost about $2 in electricity.

    just search youtube for "electric car"

    Electric motors are quite small (about the size of a watermelon) and can either bolt directly to your drive shaft or to an existing transmission depending on how you want it setup.

    The problem with electric motors is the storage of electricity. Most custom electric builds just use an f-ton of batteries... you literally kill 100% of your storage space with batteries. Most of them use up all the extra space in the engine bay for batteries too.

    It's a great concept... no oil to change, no cooling system to explode, no gas to fill up, no fumes, no, no engine vibrations, no engine noise (though that's a bad thing for some ) and electric motors can easily make just as much torque as any internal combustion engine... Again the problem is the power storage.

    In terms of "energy density" even though combustion engines have really low efficiency in terms of power output for the potential energy stored in the fuel, if you were to hollow out a car battery and fill it with gas it would contain WAY WAY more "energy" than that same battery fully charged.


    Most GOOD gas/electric hybrids use special "motors" in the wheels that also serve as the brakes and act like generators when braking...

    this helps alleviate the electric energy storage problem to a certain degree since every time you stop you're recycling your momentum and storing it back as electricity (obviously there are losses due to friction in everything but every little bit helps).... the Prius and others doe this which is why they don't need to be plugged in... and it's also why they get better city mileage than highway mileage (on the highway you rarely brake so you rarely have electric energy available to augment the combustion engine)

    ------------------

    Is this guys "kit" snake-oil... I don't know
    is it possible that someone could make a kit for ~$7K-$10K that would put motors in the wheels and cut your mileage in half... ABSOLUTELY.

    motors cost $2K-$3K a piece, the rest of the cost is batteries and regulators which cost about $100-$200 a piece, and then of course random other small parts to make everything fit together. If someone were to develop a slightly cheaper more purpose built motor (since the motors people use are off the shelf industrial motors) and combine it with a small low cost battery system they could easily price in that range and double your mileage.

    check out http://www.grassrootsev.com/ to see some of the motors and conversions people have done.

    I don't know anyone who has built an electric car personally but I do know a few people who have built fully electric motorcycles... search youtube for "quit gas" to see one of them.

    You are right on the money, twistedsymphony

    Converting a gas vehicle to hybrid is a lot of work and sounds expensive. Im skeptical about the performance too. Its much better to convert to all-electric. You wont get the range of a hybrid (you will get about 30-60 miles for an EV, more if you use AC instead of DC), but it will work fine. I just bought a Porsche 914 that has been converted to all-electric and am going to install fresh batteries and get it running in the next month or so (its been sitting for a couple years, needs a little bit of work).

    I am very skeptical about shoehorning a hybrid AND batteries into a car. Its hard enough to fit all the batteries for an EV.

    And re the prius conversion to all-electric: you can get that done now by certified companies that will NOT void your warranty.

    Im done with all-gas (except my VX of course) which I will use on the weekends and for longer trips. I plan on bicycling and using the 914 EV for every possible trip I can.

    EV Porsche 914! Where are the pix, that sound really cool!
    Cars designed by spreadsheets make sense. Cars designed by engineers make history.

    Mine needs some work, but you can view these fine specimens to get an idea of what other people have done

    Im going for a Rat-Rod look to mine: flat black with a big "Electric shock danger" sign on the doors and hood instead of a skull and crossbones

    neat 'o' rama! I had no idea so many people were playing around with this conversion. Thanks for sharing!

    There seems to be quite a few 914s converted to EV... I guess the light mid engine setup makes it a good platform

    other cars converted to electric: EVALBUM COM

    I'd love to go 100% electric... but my commute too far, for an EV to be practical.

    I've been looking into Solar Hot-water for my home... they can supposedly reduce your home heating costs as much as 80% which is quite handy. these days it costs me a grand to fill my home heating oil tank, and that gets done 4 times a year

    If battery tech was to improve such that they were half their current size with double their current range, and roughly the same price, I'd probably convert nearly every car I own.

    EDIT:
    Wouldn't you know what article I came across on my daily visit to hackaday.com Apparently MIT found a way to store engery with water that is more efficient than modern batteries.
