What a shame that the low bid mentality has doomed such a great invention as the Sterling engine, which operated with no water needs or the use of long loops of fluids, such as with other CSP systems. Imagine what would happen if we all only bought low bid items; we would be surrounded by junk in most categories. Not to imply that PV is junk, but the Sterling engine system is worthy in it's own right. There is too much emphasis placed on only the bottom line. We do not use that in other areas of life for good reason. Often times quality and other concerns show that the best value over time is found by first considering need, local conditions, and long term usability, then price. I hope the new owners will continue the design and it will not disappear.

Yeah its a shame, I've wanted one of those in my yard, ever since I heard of SES, back in 2000!

aligatorhardt,

These stirling engines do not offer any benefit over PV. Just moving parts and the reliability issues that come with them. You think the long fluid loops of solar trough technology is a disadvantage. Think again. They enable heat storage in large tanks to generate on demand solar power.

The solar power tower does not have these long loops. Will that be the winning technology for on demand solar power with cheap storage?

The progress means that even good technologies are found in museum. After 150 years, CSP is no exception

Some industry pundits have long said that PV would be the "Crazy Eddie" of energy production. Someday making ALL other forms of energy production obsolete. It's looking more and more like those pundits were correct.

New CSP and storage innovations from Shec Energy:

With the unique solar receiver design,I understand the conversion efficiency is around 30 % and heat storage at 850 degrees C, much higher than molten salt.

John writes in comment #5: "Some industry pundits have long said that PV would be the "Crazy Eddie" of energy production. Someday making ALL other forms of energy production obsolete."

As I recall, "Crazy Eddie" started off with a cult following but ended up in prison for fraud and his business went bankrupt. This seems like a Freudian slip to me.

Solar insolation for London is roughly a factor of ten higher in July than its value in January yet the largest demand for energy is for heating. This alone should suggest that solar PV is not going to make "ALL other forms of energy production obsolete."

Stirling Engines are really neat... but @Anne_van_der_Bom makes a point.

CSP is flawed in it's overconsumption of water (you think peak oil is a problem, wait till we hit peak water)

PV is flawed insofar as energy production remains intermittent.

Ultimately, I doubt "ALL other forms of energy production..." will ever be obsolete...

except maybe Nuclear fission. That's bad idea jeans.
