AHAha! scaled up RC technology :) maybe you can do the solar charging also :)

I saw a citroen 2cv converted that did 60kms and weighed the same as the factory model yet accelerated at 3 times the speed.

Gov and Big wigs couldnt let Serbian technology rule over Edisons as that would ruin cartels.

With high Oz dollar, Lithium batteries are getting cheaper however I would have loved Zebra batteries before they were bought by GE the Rsholes never to be liscenced for EVs. The Zebras used molten sodium aluminumchloride (NaAlCl4) cheap as chips but now only used in remote locations for telco and other comms bases/antennaes etc would have solve base load energy storage issues of wind or solar hands down. Wasnt the most powerful battery for EVs but young technology and even Rolls Royce and Mercedes Benz had EV prototype limos using them.
