gg .. ...I am betting it will be batteries such A123 or VLNC feeding efficient wheel hub motors directly (UQM) ...no transmission ,the wheel hub motor being the transmission. I share your view for future electrical transportation .. I've also researched the various publically traded companies in this space ie ALTI/UQM/VLNC/ZBB/VRBPF.pk etc and wonder if any of them are capable of commercializing their technologies prior to burning thru their available capital ?? Just can't pull the trigger on any of the stocks .. Triff ..

gg cox: "Depending on the volume of the air tanks and the pressure, you could graph the loss of power and distance travelled as the air in the tanks deplete moving the car." very true. exactly the same for batteries. gg cox: You would probably have no problem climbing a long hill on fully charged air tanks...how would you do climbing same hill on a quarter of original pressure and volume?Similiar to batteries ...no? Have you ever used air tools?If using air sander for example, you can feel the loss of power, and hear it, as the air in the compressor tank goes down to the cut in point of the compressor and build again to cut off." i think we have a misunderstanding. i meant that if one leaves a charged tank alone for a few days it will have the same pressure(power) when you return as when you left, provided it doesn't leak. a battery on the other hand would show a measurable loss of power. i know you know these things, that's why i said we have misunderstanding. (VRB might not show a loss of power but can't as yet be scaled down to car sized batteries.) on a different note..scuba tanks would not be functional for diving unless they weighed as much as they do. i believe stronger tanks made of material such as kevlar or another material could be manufactured than would drastically reduce the weight of the tank(storage system). then you would have a storage system that is light weight and remain with the same power it was stored with until it was used. hopefully compressors could be built much lighter in the future.
