[Milsurplus] Little "Field Day" Genny - ethanol/gasoline

[Richard]

It's not only not hot enough, it's very corrosive.  25 or 30 years ago I 
visited a geothermal test site in the Southwest, and everything was 
dripping green or red with corrosion.  I suppose it's site-specific, as 
geothermal is successfully used in Iceland.  It wouldn't be easy working 
with a Witch's brew that gushes out of the ground corroding everything 
it touches.

Otherwise smart people are looking toward self-interest.
