Peltier questions

I can't do that Dave

2006-12-18, 1:25 pm

Hi,

I did a search but most results were concerned with cooling. The fan on
this website uses a Peltier set up to run a motor.

http://www.modernoutpost.com/gear/d...an_airplus.html

At $125 it seems a little excessive in cost. I have found a 50W Peltier
for $15 and am now wondering what would be involved in making a few of
these for my home.

I live off the grid by the way and have 550W of solar and 450W of wind
so anything I can get that offers relatively free power to move heat
will be a great help.

Thanks in advance.

Dave

ThermoElectric Technology is a very viable Remote Power Source, but
isn't really very efficent, when compared to ICE.
I have a Propane powered 240Watt TEG (ThermoElectric Generator) that
burns 1 USG of Propane every 24 Hours. NO Moving Parts, is an advantage,
but 5760 WattHours/Per Gallon isn't considered Efficent in anyones book.
I use the waste heat to keep my Power/Well House above Freezing, and
that helps mitigate the inefficency, but still, it isn't really the best
use of those BTU's you buy in the Propane. Now when you figure in the
OEM cost of the unit, ($5KUS) just about everthing looks better. I got
mine basically for free, for hauling off a MountainTop when the Radio
Site was abandoned, and a friend with a heliocopter. I also got a
AbsolyteII 800amp/hour 24Vdc Battery Bank that was only 3 months old,
at the same time. Not a bad score, but if one had to front OEM costs,
he better have "More Money than Brains".......

That must have been a pretty capable helicopter, nothing like the R22's that are
buzzing over my house all day. How many trips for the batteries?

Thanks Bruce,

I wasn't sure where the Peltier was in the scheme of efficiency. I
guess I will pass.

Appreciate the help.

Just one trip per bank, we were using a modern version of the French
"Alloette". These can sling load a 500 USG Diesel Fuel Bladder to
8000 feet with no problems. Big turbines are your friend. Nice to have
friends, with "Cool Equipment", and contacts with US Govt. Contractors
that would rather have someone else dispose of all the Old Stuff coming
off these Mountain Top Sites.

Bruce in alaska keep seeing you on the Stak but you never Chat....

It must be great to have friends in high places.
