I noted in the Technology section that you are using bent glass panels. Have you considered mylar? It would significantly decrease weight and cost. You could even make them portable.

Hi, I love this design. It's very practical.
however, you have a serious mismatch between the dish and the collector. I expect you have fixed this by now, but the diameter of the black cylinder must be slightly larger than the width of the mirror strips. The design in these photos is throwing away at least half the power.

Another thing, the collector needs to protect the hot surface from the relatively cold air around it. The backside of the cylinder needs to be insulated, and the front side needs to be recessed within a cavity that shields it from the air. A surrounding skirt would capture more hot air around the hot surface and protect it from heat loss.

it would be really cool if you make available a kit of rods to create the frame and the metal axis to mount the frame on a post. Then people could erect their own post and find their own mirrors locally. The frame is the real technology here IMHO. A tracker mechanism would be another box you could sell. Give us the technology in a form we can put up ourselves and you will have a huge market. Selling the whole thing as a unit will price it out of reach of many people.
Good luck,
John

Another thought, some of us want to hang stirling engines out there instead of steam generators. That adds a LOT of weight. The two axis rotator at the post needs to make provision for a really healthy frame or pole extending from the rotator to the heat collector with the option to counter weight the collector behind the dish. I'm asking for a design that is not custom designed for a single type of pole but has the strength to support 1000 pounds passing through a hole in the rotator mechanism along the axis of the dish. That way, we can hang most anything out there on the end of that arm and convert with a Stirling or thermoacoustic arrray. All the volume in the shade of the collector needs to be available for the Stirling engine since it seems impractical to place the engine beyond the collector due to the long focal length.

When can I buy one?

I want to be able to convert

Hi, My apologies. My comment about the solar collector size being too small was wrong. I see now it is oriented across the mirrors and the dimensions appear to be reasonable, assuming the mirrors are not distorted from the proper curve.

I think that solar is the way if you love somewhere that has a lot of sunlight. I love solar energy anyhow.

Thanks a lot for these pics up.
