[ausev] Electric is good, but ...

Thu May 17 01:58:02 GMT 2007

Another person suggested a linear alternator and that
would simplify the system even further. My idea was to
use relatively low-pressure steam anyway. Perhaps
doing away with rotary motion would be more efficient.
 I will add that to my document as a possibility.
Thanks.
