Stirling solar dish
« on: January 19, 2007, 01:35:58 AM »
How can we make one of this?

http://www.stirlingenergy.com/solar_overview.htm

so far I think this is one of the most efficient ones but I want a bigger one
 yeah ........that's every man's wish ::) ;D

and how about this:

This guy is amazing now someone put his videos online, a shame he deserves the money he was asking for them but let's honor him at least by proliferating the cause >:(

Cheers

Yeah, very interesting!

 Unlike usual solar powered units this little bugger is kinda noisy  :D

Would like to see that 30 foot dish in operation though - lots of Kilowatts!

thanks for the post  kukulcangod

I like also the idea of using stirling engine to use the sun energy. But my problem here is, it needs a reflector to focus sun rays and it need to change the orientation based on sun position which is hard to do. So i seach for alternative ways and i found this flat stirling engine. If i covered the top side with black paint, it will absorb sun light heating the air inside powering the piston and generator. It is also more efficient than conventional stirling because it uses diaphram instead of piston does reducing the friction. Using flat stirling engine, the reflector can be eliminated and doesnt need orientation to the sun.

The main disadvantage is the low temperature rise and therefore low Carnot limit.
