* You Don't Really Want A Patent, Do You?
* Don Lancaster's Patent Avoidance Library.
Don discusses many of the pitfalls of obtaining and keeping patents. He makes a convincing argument that there is no need for obtaining a patent unless the gross sales are greater than $12,000,000.

("Receiver Axis" Lighting Heliostat similar to the Silbermann mechanical heliostats of the 1830's. It uses the pantograph bisector mechanism. It's a bit difficult to recognize the "Receiver Axis" function since the mirror moves in AZimuth ALTitude but its there. The receiver axis in this case is Vertically oriented. Note!! even though the mirror moves in AZ/ALT this must be called a "Receiver Axis" heliostat mount.)

(Basically a Receiver Axis Heliostat. The mirror is composed of Fresnel mirror segments arranged as multiple rotatable slats. The segments in each slat are slanted to accomplish concentration with a fixed focal length in the plane 90 degrees to the Sun/Receiver line.
The slats are rotated with a rather complicated mirror adjusting mechanism to accomplish concentration with a variable focal length in the plane of the Sun/Receiver line.
I have described this variable focal length problem a number of times on the usenet as long ago as 2001, (probably earlier).
This is an interesting method of doing this.
This appears to be a rather complete all mechanical solution.

Tensioned reflector support system
(The Russell Concentrator Reflector Heliostat is one of the important basic solar concentrator types. It has spawned many imitators and variations. The Russell Trough is not considered to have Fresnel characteristics even though the mirrors are composed of long thin strips. It is a true heliostat having geometry that constantly change throughout the day.)

The "Minto Wonder Wheel" is horribly low in efficiency due to the wasted energy needed to heat and cool the thermal mass of the liquid just to get expansion of the gas. Baer attempts to minimize the heating of the liquid and maximize the heating of the gas. Though not perfect, Baer's design is much better than Minto's.
Minto didn't patent his wheel claiming to give it to the world. Actually he gave it away as it was never going to be very useful except in very special applications such as a moving sculpture.)

The storage tank was a light weight fiberglass pressurized to 3500psi. The high pressure was reduced through an expansion pressure regulator to 500psi.

( <Robert L. McWilliams III >in an email to me wrote:
I did some serious and time consuming digging around, but I think I have at least narrowed down the time frame. The earliest reference I have to a patent for dichlorodifluoromethane (CFC-12, R-12, Freon 12) is 1934. It was originally patented by a joint venture company formed by E.I. DuPont de Nemours and General Motors. Freon was originally trademarked in 1931 by E.I. DuPont de Nemours and covered all of their halocarbon products. Allied Chemical Corporation began producing its own dichlorodifluoromethane in September 12, 1951 under the trade name of Genetron. 1951 - 1934 = 17, the number of years granted an original patent so 1934 looks like the year that R-12 was patented. The original patent number is 1,953,216.

Vertical-axis wind turbine with two-phase sails
(Flapping Sail with interesting method to control the opening and closing of the sail by mechanical communication through connecting lines. The sails are triangular. As I see it, the basic improvement is in the mechanical communication through connecting lines. Similar patents without the communication lines are: DeBerg and Weisbrich. I believe these two patents are direct prior art because they, along with Green, maintain the shape of the sail by use of a single strait spar and flexible lines. Less similar prior art are: Chen and Goldwater. These patents maintain the shape of the sail using lines and meshes. Barnard obtains the sail shape with a single curved spar and without the use of either lines nor meshes. Other patents, Hillman and Rhodes, communicate the position of the working sail to the idle sail by use of a rotating shaft. This mechanism is similar to Green's use of communicating lines. All the flapping sail patents have similarities to Green's flapping sail patent.
