Hi Paul:

Regarding "perpetual motion" I think you are dooming inventive ideas to perpetual failure.

How about a mechanisim using conventional sources of stored power that while in use recover about 80% to 85% of the power that was expended in the first instance. Start with 50% if you do not yet achve adaquate inspiration.

I have been thinking and dreaming about such mechanism for quite a while in my spare time. When one gets the efficiencie higher it will be very useful.
