RE: [Solar Turbine] Solar Power Generator Review

[b...@windwavesandsun.com]

This work is better compared to SOPOGY than to Ausra.
I note in the discussion that (Marcin?) asserts the receiver should be the width of the mirrors plus some 11mrads or so of error, while Xiao points out that even a Compact Fresnel design like ausra uses a curved mirror, and thus the receiver is much much smaller than the mirror width.

To curve or not to curve is a fundamental question because every other dimension is based on the method of curving (one cannot curve a 3" piece of flat glass - but one /can/ curve a suitable length of flat glass). The option of molding a curve is I think cost-prohibitive in this context.

Servo motors are quite cheap, one needn't plan on making them from scratch.

Please view the discussion I had with Gang Xiao, inventor of a trough
system that he claims is better than Ausra and much cheaper than other
large troughs. He's intending this for the home market, and he
expressed interest in collaboration on the steam engine, as that's
also his engine of choice.

See his work:

I am inquiring on his licensing arrangements and fabrication
requirements.
