No they aren't. They give these cells to John to generate publicity, in order to get OEM's interested in purchasing them for production auto applications.

There is nothing we can show the industry they don't already know. There are thousands of professional engineers working on EVs in big companies like GM, Tesla or VW. They are not stupid.This is really a great project, exactly what is necessary to show the industry, and the world, what an efficient vehicle is capable of. Since the general public is most concerned with range, this could be as important as the racing efforts, maybe more so.

Creating / encouraging public / consumer demand is a very worth while investment ... that is why there are $Billions spent on Advertising.It took Tesla building the Roadster to catch the public eye and get the industry motivated to start building actual EV's. It's not a practical car, and the industry could have built something similar, but they lackd the vision and motivation.
DC motors are flying apart at high RPMs (been there, done that - twice) and suck efficiency wise at low RPMs.What are the problems? Have you have problems with your DC motors on the highway? I would think direct drive would excel on the highway and have trouble with stop-and-go or steep hills.

They aren't marketing to you, or ev enthusiasts in general. They are targeting the general public, and to many of them more vehicle mass is a good thing as it is perceived as safer. Many of the public also care more about how many kids, dogs, and groceries they can fit than they do about Cd. You can give them what they want or try to take on the job of educating them, which generally gives low ROI I think. So far manufacturers have added electric motors mainly to give more power and improved acceleration in the kinds of vehicles they know sell, since they know increased performance also sells, and increased mileage isn't as much an issue until gas prices go up over $4.00/gal. I drive a little electric Swift and think it works fine for most of my driving, but that is not what many of the public think, and if you want to sell in high volume to get costs down as you said, you have to target the majority of the public. I think when gas prices go much higher, there will be more interest the the type of vehicle you described, and once the manufacturers see the market is there, they will start building them.My biggest problem with the industry is they aren't attacking the range issue the correct way. Since the batteries are still the most expensive part they should put more emphasis on getting the most out of those batteries, which means greater emphasis on aerodynamics and weight savings. The LEAF could have had a much better cd and could have been lighter, both of which would have increased it's range significantly. Good aerodynamics shouldn't cost any more to build than poor aero. Light weighting might cost more but it's probably cheaper than adding more batteries, and once the design is done and volume production kicks in the extra costs of lightweight design and materials will be reduced per vehicle.

I have recently built our AC system into the BMW. I won't be using DC much any more. Only one project is still using DC - the off-road buggy we're building.Got it. So does this mean you'll be using trannies or going to AC?
