adding batterys
 

i have heard of people more then doubling their city mileage in their hybrids by adding many more batterys.   is this true?   makes some sense, but double?

Yep, this british company messes with priuses to get 102 MPG out of the box, you gotta plug in, but damn, for that kinda mileage who cares? Anyway, they just added more batteries, so depending on the batteries you add it seems very possible.

102 MPG Prius

Re: I found an article about it for an article I wrote
 

Been there, done that. Just remember, you gotta pay for this stuff and you gotta pay for the grid charge. It just doesn't make sense financially. The Prius at the tour de sol last year got 102 MPG. But after the run, they made them recharge the batteries with the engine. They ended up with less than 70 MPG. Heck, with the right techniques, anyone can get 70 MPG with a Prius as long as temps are 60F or above. And Im not talking about pulse and glide. I'm just talking about the standard fuel saving drivng techniques.

yup
 

Yup the only way to go is to add high output solar panels on the top of the car so that you get energy for free as you park or drive in the sun. Anything else is burning fuel somewhere else and wasting energy in the conversion. Actually if you add solar panels to a regular car you lighten the load on the alternator while driving and keep the battery topped off when parked to offset losses and any alarm battery loading. The only advantage of having larger batteries in Hybrid would be to absorb more braking energy on long downhills. The lead foam carbon batteries being developed with make larger batteries more economically viable with lower cost higher energy density and longer life. Look for them later this year early next year.
