Lets see if we can find some perspective to place this in... As electric vehicles near production, the effeciency, size, and power-weight ratio will lead to designing vehicles with motors at the wheels. Either two motors or four motors on each vehicle. Now let us look at a minimal electric vehicle with current technology. Probably a sub-compact with a strong light-weight chassis, a lot of light-weigh t materials, batteries, and two electric motors on the rear wheels. This would give it 40 Horsepower. How does this compare with current vehicles? Hmmm.. I have a beat-up 1975 Mercedez 240D. This is a compact car and fairly heavy. The diesel engine is a 2400 cc power monster with a whopping rated 65 horsepower. Now, I use every engine elixir I can waste my money on, so I am probably getting most of my 65 horses. I am seldom left at the light by anyone (more of a tribute to my wild diesel driving style.) Most of us have been annoyed by diesels creeping through the light ahead of us. But these are often cars over 15 years old that probably have barely over 40 horses left in their engines. Now lets compare this to our minimal EV. We will have a car with Two thirds the weight of my car powered by two thirds the horses. This wouldn't change my driving style... I am looking forward to being one of the first people in the world to get a deal on an early model Flywheel powered Electric Used car (Its my style.) It all seems possible to me... Ted..
