It can't possibly be that it sucked and no one wanted to own one except as a vanity item, right?
My Dad and I tried to put together an electric R/C (remote control) car in the late seventies using the technology of the times.
The problem wasn't the motor or the controller, they worked just fine. The weak link was the
battery.
All that was available were drycells that go into your flashlights and NiCads that had to be combined in massive numbers to get the required voltage and amperage so it ended up being really heavy. We even tried a big ole GelCell motor cycle battery but it was so heavy the car could barely get out of it's own way.
I think the best we could do at that time was about 15-20 seconds of decent acceleration before the battery was drained. Quick chargers weren't widely available so recharging was an overnight process.
Things are different nowadays.
Light weight, high capacity Lithium Polymer and Lithium Ion batteries (Think of them as large fuel tanks) are widely available and getting rediculously cheap. And that's the key to making modern electric cars a success.
I switched to all electric for my model airplanes about ten years ago because modern batteries and modern electronic are vastly superior to the fuel engines that we used to use. Powerful, Quiet and Clean.
What doesn't get talked about, and this is not discussed amongst the "Green Crowd", is that electricity still has to be generated for all these electric cars. They seem to think windmills and solar will fill the bill.
It won't.
We need Oil Exploration and drilling, on shore and off shore as well as Nuclear Power to keep up with the demands all these batteries will be placing on the Electric Power Grid.
