I know a number of ya'll follow developments in solar energy, which could
have implications for more energy available on our farms. Here is an
article about an acoustic engine that could be driven by solar heat. I read
about this device about 2 years ago in Science News....This is cool. This
stirling engine could conceivable drive heaters and refrigeration units.
Simple, driven by acoustic waves in helium gas.
Check it out
Ted.

Ted,
Any engine 10% more efficient than others sounds interesting. How do I
get more information?
Thanks!

Hi folks,
a guy from another list is asking for subscription info for this and the =
hydroponics list. Due to the crash I mentioned in my previous post, I don=
't have this info anymore, and want to ask you to send it to me. Thanks =
alot!
Uwe

Thanks Ted,
As a long time alternative energy and self-suficiency buff I was glad to
hear about this. It really has my curiousity going. Not much detail in the
Fox article. I'm looking for more.
I'm familiar with the sterling engine but can't imagine how the sound,
generated in this engine, powers one. I have seen sterlings used with solar
concentrators. This must be more efficient than going direct from the solar
to the sterling.
Let us know if you find out anything else on this.

How does an engine that runs on no fuel and is perpetual, produces 240 volt
50 Hz and the by-product is oxygen sound as an efficient product?
An Australian company has just gone public float on the share market
recently and is having their plant built in Germany to begin production
within the year.
It's called I think the "linear energy" engine.

Come on folks - this is getting ridiculous / insulting !
If there is energy coming out, there is:
energy going in, or something being used up.
It may be better, cheaper, cleaner, and more efficient (all of which I know are
possible). But there is no engine / turbine / machine that runs on "nothing".

Carolyn, What are you referring to? Did I miss something? Please bring
this old sailor up to speed.

Hi Ted,
I figure she's referring to Andrew's post below.
The closest thing to perpetual motion that's actually working is OTEC (Ocean
Thermal
Energy Conversion) which uses the temperature differential of the surface
and deep
waters.

I've seen some preliminary specs on this OTEC stuff and it looks great. It
is not "an
engine that runs on nothing".
Here is a link that explains it. http://www.pcj.com/OTEC.htm
The graphics on the above page didn't make sense to me - I think most of
these systems
*pump* the cold water to the surface and use the temperature gradient in a
somewhat
similar manner to the way the cooling loop of RV(propane) refrigerators
work. I have
seen much better descriptions of how this all works on anohter site, but
can't find the
URL to send along.
another source at http://charging-ahead.com/ states:
Of all the oceanic resources studied over the years by the U.S. Department
of Energy,
the DOE has found that Ocean Thermal Energy Conversion
(OTEC) could make the largest potential contribution to U.S. energy systems.
OTEC power
plants exploits the temperature difference between
warm surface ocean water and the colder water found deep below the waves;
the "thermal
gradient" is used to operate a heat engine to produce
electricity. But OTEC requires construction of a relatively high-cost
central station
power plant that is unlikely to be broadly commercialized anytime
soon.
I have no idea what any of this has to do with fish culture, but it is an
interesting
topic anyway.

I first heard of it in Marshall Savage's book 'The Millennial Project'
several years
ago. Great potential there for clean energy. A OTEC type system cold work using
waste heat from manufacturing processes. I love to see them running at steel
mills,
conventional power plants, etc.
You can learn a great deal about OTEC at http://www.luf.org
1278 hits when I searched the site for 'OTEC' just now.
To bring this thread full circle (back to aquaponics), an OTEC would also
create an
artificial upwelling zone by bringing nutrient rich waters from down deep and
creating a virtual aquatic Eden in otherwise barren areas.
