[EVDL] CSIRO motor compromise.
The 98% efficient CSIRO solar vehicle motor is a bit expensive like 10k dollars. What is a good compromise today for a brush less motor that is affordable and powerful enough to allow a 500 to 1000 pound vehicle to keep up with traffic. I need to get under 100 wh per mile. I've heard of some motorcycles that can do 75 wh per mile which would be very good but I'm skeptical that they really achieve that kind of efficiency. My vehicle will be much more efficient than a motorcycle. Lawrence Rhodes -- next part -- An HTML attachment was scrubbed...

My vehicle will be much more efficient than a motorcycle. Much depends on what you mean by keep up with traffic. If you want low energy consumption, an ebike, not a motorcycle, is the way to go. Even an indifferently optimized ebike can usually manage 20 Wh/mi. With some pedaling, you can often cut that in half. Of course, the traffic it can keep up with tends to be two-wheeled and pedal- fitted. PS - Addressing EVDL posts to ev-requ...@lists.evdl.org is kind of futile.
