Andries made a comment (probably off list) regarding 1250 F being the
practical upper limit for super heated steam --

Andries -- take a look at:

1300 to 1400 "C"

And last -- in 1995 --

Present Status of World Geothermal Energy Development

 The total capacity of geothermal power generation in the world was
approximately 7,231 MW as of 1995. Geothermal power generation is playing a
major role in countries with a small demand for electricity, such as the
Philippines and El Salvador.

Folks;

Waste heat retrieval is all about delta T's - that is difference between
top temperature and lower temperature.

Just how small can that be??

Well -- the Japanese are planning some big projects working with a delta T
of just 18 degrees C.

Guess they have more of an eye to the future than fossil fuel dependent
countries that believe the present situation can go on for ever and one day.

Hit:

OTEC(Ocean Thermal Energy Conversion) and Experimetal System 

(Yes -- I know Experimetal is not spelled correctly -- but the above is a
copy/paste -- so what can I say?)

Also -- browse around -- you may be slightly shocked regarding just how far
Japan has gone into refrigerant cycle systems - and at a "large" scale.

I get the feeling this list believes I have "invented" this technology out
of thin air.

Not true -- I simply have adapted this technology to solving an efficiency
problem we have with acquiring boiler systems of reasonable cost that can
produce power at high efficiency. Big difference.

However -- it is easy for me to demonstrate -- through prior art on this
subject -- that refrigerant cycles are indeed a well developed science --
even if it is regarded as next to black magic by members of this mail list.

Remember -- I am supposed to be the "provincial" mentality guy -- stuck
here in technology backward little Belize -- not you folks!

Refrigerant extraction of waste energy in a traditional bagasse fired
boiler -- as we have here in Belize -- would more than "triple" power output.

But unfortunately -- that industry is dead! We can't count on bagasse fired
in fire tube boilers much longer.

Maybe in another 1000 or so years though -- next turn of this wheel of
human existence.
