Hi guys,

I want to thank everyone that took the time to read my post today. I'm Sean and I'm working on a concept to double the range of an electric car using renewable technology. I want to get some input from some EV hobbies that have work on building/converting their own EV to get an understanding on how the community view the technology.

Below is a link to a survey I built to collect your feedback:

Also I would love to chat with some of you guys via skype if you are available.

My goal is to build the first 1000 miles per charge EV, and this is just my first step towards that goal, Your support would be greatly appreciated.

Best Regards

P.S. Please feel free to comment and I will answer any question to the best of my ability.

Update:
I'm not trying to sell anyone a false bag of goods, I know the limitation of these technologies. I only want to know what's a good ROI to aim for with these technology for EV practitioner to see it as a good investment. Once I know that, I will know whats worth your time and money.

I wasn't impressed with the article, even a tesla can get 460 miles @ 20mph (which looks like the cars top speed)

edit: 450 mile real world record

and they are making a DISPOSABLE battery...

how much time/energy does it take to make new batteries out of the old ones?!?

I don't think 1000 miles between battery swaps is going to be nearly as convenient as plugging in when I get home, and there is simply no way in hell it will cost less with distribution and refurb and whatnot.

the electrical/mechanical efficiency drops at low load, and wind resistance/etc take their hit at high speed (note, added a link to 450 mile record).

re: aluminum car, if you packed a tesla sized pack in a streamliner, it would go very far (and probably hit peak efficiency at a lot faster than 20mph).

sorry for the edits, but here is a streamlined 1000 mile example from 2011: http://www.popsci.com/cars/article/...-ev-distance-record-driving-1000-miles-charge just a 23kwh battery, air resistance sucks more than anything.
