The dish is number one priority right now. To design and build the 20 foot rectangular frame. I plan to use an aluminum grid of 2" tubing to support the individual mirrors. The tubing will be rolled into a radius of 13 feet allowing the collector to be out in front of the dish so that the reflected rays come at the receiver collector more head on...Strait in.
The mirrors made to be 4' equilateral triangles as first choice or if that proves to be to expensive then 4' square mirrors. Each design needs to have three mounting points for ease of adjustment. They can be made of anything light weight, cheap and durable. Aluminum, plastic or Evacuated mylar film over a support and mounting frame, or any other material.
If anyone can give quotes on any idea for a mirror this size please do get in touch. [Contact Me]
I think this in itself would be an endeavor that would bring in some capitol. Do it your selfers would buy these mirrors and use them in their own projects. This would help to finance the rest of the project.
The base will be steel for strength and durability. For now paint but Galvanization would be best. Plasma cut gears welded to rolled tubing to keep cost down and yet to handle the wind load. Driven by gear motors.
East to west axis should work as an electric clock driven by a ac 60 cycle gear motor, and north to south guided by a sun follower electronic devise. This way it could work any where on this planet without modification. At this point we need people that can draw prints of this so that it can be made.
