You're welcome.

No Thank You Frank!!!!!

I'm pretty sure it would have to be separate; otherwise the alternator would try to recharge the batteries, resulting in lower efficiency.

so when can we expect to see a prototype?

Would you use it to re-start also? Seems like a good idea to me. What sort of batt setup are you looking at?

Have you considered storing the energy as compressed air? An air motor is very compact. Have it pump air into an (LP) gas tank (in the spare tire well?) while braking, then use that compressed air to drive the motor during acceleration. If I calculated correctly, you can store about 100 Joules of energy per litre of tank and atmosphere of pressure. So a 5-gallon tank pumped up to 100 psi has enough energy (13 kJ= 3.6 Wh, ignoring losses) to accelerate a 2400-lb car to about 11 mph. Not too bad, relatively cheap and needs only a very primitive controller. This is sort of a surge regenerative energy concept like they're designing for Formula 1 cars.

I've been looking for places on my car to couple the energy in. The only place I found was the inner CV joint housings on either side of the differential. These are sturdy, 100-mm-diameter cylinders that you could theoretically attach a drive belt or rubber roller to.

Ok -- I just signed up and I just found this site -- and wow -- what a bunch of open minded folks -- thank goodness. Ok -- I call this idea a Hybrid Adapter -- or HYBRAD -- as we are adapting to the situation at hand and making a hybrid out of our existing car.
There are a few ongoing projects -- please go to my wiki page which is hosted at the PESWIKI project -- link at http://www.hybrad.com

These HYBRAD efforts are all still on the ground floor as far as I'm concerned -- it is a good time to get in and produce some solid results -- modifying your ICE car and making it a hybrid is not rocket science -- but you have to put some effort into it. I'm building my "fifth wheel" out of a Ninja 250. This other guy built a "pusher trailer" -- see the wiki page.

I'm looking forward to working with you all and really glad I found this place.

Welcome to EM! Sounds like you're working on a ground-up Electric version of these "EV Extender's" :

Mike Chancey's Civic Pusher Trailer


EV Pusher Trailer


Idea: The shape of the trailer could accommodate a tear-drop "boat tail" shape to "complete" the aerodynamics of a car.

I think that a trailer is a lot more intrusive than a fifth wheel, which is in turn a lot more intrusive than the OP's idea. But perhaps with that intrusiveness comes even greater effectiveness?

The trailer can often offer an aero benefit as well. Budget can impede this design tho.
