Kender Solar Engine

Dear Forum,
Is anyone familiar with this one? It is a Stirling engine that uses a
turbine instead of pistons. Here is their website:
http://www.kendersolar.com/
Do you think this is feasible? How likely do you think is it that they
can make it work as advertised?
They claim that the energy extracted by the solar panel produces more
energy than what it takes to drive the compressor to circulate the
helium, and results in: "The system produces 39 kW of power (47 kW by
the turbine, less 8 kW for the compressor). That is equivalent to 53
horse power, or enough energy to supply energy for 12 homes."
Thanks!
Mike

"It is a Stirling engine that uses a turbine instead of pistons." Simply NOT true.

From their own home page they say "Similar to a heat pump or a Stirling engine." They do not claim it to be one! Take note that it is in development and they are looking for investment capital.

I apologize. I am no expert on the technology. That's why I am looking for opinions!
Best regards,
Mike

If you will do a little research on Stirling engines you will find that they operate on a gas, usually air but sometimes on helium or hydrogen. Never on a liquid/gas via phase transition. Follows is a link to Dr. Izz's online text book information on thermodynamics and Stirling engines. http://www.ent.ohiou.edu/~thermo/

Lastly try subject searches using the Yahoo search engine.
