3 part movie, wow. too bad he has 50% battery left after only a 15 mile drive. i couldnt make it to work!

I remember seeing that car awhile back, I think it's cool.
Here is a link to a company I found awhile back that has a kit for the Festiva. http://www.e-volks.com/geo.html

thats a load of batteries..... i think someone should come up with a pedelstiva

This is what I want to do with mine, Jay Leno has a couple of Festivas' and I think one is electric.

That kit isn't too badly priced, but man, it says it can only hit 55 mph.

I think a diesel/electric hybrid would rock. Run the electric around town and when the battery gets low fire up the diesel to charge it and cruise out on the highway.

i would love to do the EV conversion kit but what im thinking is, why not figure out a way to hook up a generator to charge the batteries via the cars movement.. theres got to be a way to do it.. then you never plug the thing in ever again. the #2 kit is 72V DC right? so get a generator that can put out over that amount and some thing to prevent the generator from overcharging your batteries. same concept as a gas powered car's alternator. what kind of voltage does a alt put out? whats to stop someone from taking one or 2 alts and doing a chain and sprocket setup on the rear wheels to generator power for the batteries?

It doesn't quite work that way. The generator wouldn't make power equal to whats being used to move the vehicle.

[MTec007]

i dont understand that. there has to be something out there that can put out over 72V DC current at whatever RPM's the tires spin at. or if not, if that dont work there is one more tire in back, that should surly do it. if not, use the from two tires as well. there a lot of spinning going on, and it could be put to use! i wish i was a electrical engineer, i would do it then.

i didnt say cheap did i?

SR200.24 125 amp. 24 volt high current modular alternator compatible with both positive or negative ground vehicle electric systems. Requires A or B type external voltage regulator - order regulator separately. (NOT recommended for welding applications).
Approx.Ship.wt.= 24 lb.
GO TO Detailed 125A 24V Alternator Specifications

$725.00

4 of those will do it definetly.

after that you could rock some flexible solar panels on the roof for extra umph

[big_ty2003]

I think you would need to get some unobtainium to make that work.

[bhazard]

Its never gonna make more than what its using. That would be "unlimited energy" something that just doesnt exist.

[MTec007]

i dont get it. if its putting out combined at 96V and 500amps and the motor is only using 72v then whats the problem? heck you could weld sprockets to the half shafts and hook as many alternators up as you can fit under the hood, with the batterys in the way

We offer our Kit #2 standard with an ALLTRAX 7245 PWM(pulse width modulation) controller. This controller is rated at 24-72 volts DC and 450 amps. The Alltrax Controller is programmable via a computer and an adaptor cable (RS-232 TO USB). For higher performance see Kit #3.

450 amps? thats covered too!

If you were an electrical enineer you would understand why this wouldn't work. You are constantly going to be losing energy.

Here I did your work for you and googled it...

A generator to recover energy upon braking would help put some charge back in the battery pack, but if you hook up a bunch of alternators to the axles you'll increase the load on the electric motor and make it use even more energy!

What Mtec007 was describing was essentially a "perpetual motion machine," which goes against the most basic physics laws. Won't happen.

Think "friction" when you are planning these things.

Yes dude, alternators aren't free energy. They actually put a decent drag on whatever they're hooked up to. And the more power they generate the more energy they use.
