This is actually great instant coffee. This Fresnel Lens is one of our new lines that have been custom made for a small lens with a very long focal length. This allows for good greating without the lens getting too close to the heating surface. This is a UV material estimated at 5-7 years. This will be our new line of Spot lenses once the process is fine tuned. Also page magnifiers have a very small focal point and a very short focal length. Music Purchased from Stock20.com Excellent music for productions.
This solar stove took about 10 minutes to throw together and we actually use this on almost every sunny day. It can cook frozen chicken, or turkey burger meat in under 20 minutes. This is a much safer method of cooking than the Fresnel Lens.

Boil water just by placing it in the sun. www.greenpowerscience.com This is a simple process to make your owns solar evacuated vacuum tubes from any bottle and a vase from Walmart.

www.greenpowerscience.com This illustrates an easy way to transfer power from one place to another. It is very inefficient but does work. A better solar panel would yield better results.

www.greenpowerscience.com This is a 75 cu ft Solar over that took about 5 days to build. Every connection is sealed with silicone. The maximum air temp measured with all the mirrors in place reaches 221 F with 70 F outdoor temperature. We have a bit more work to do as 2 collection panels are wood and cannot handle the heat of the mirrors. The floor is plywood an is not affected. Without the mirrors the maximum temp achieved is 201 F. Raising 75 cu ft is a task. This oven gains about 3 F every minute up to 150 F when exposed to sunlight with no mirrors. After that it increases 1F every minute. Woods ignition temperature is higher than what we will be needing so the frame works well and is an excellent insulator.
This video was shot on a cold Florida Day. 46F. The water was 56F. and reached a source temperature of 135F. After the 2 feet drop and outdoor leaching the collecting temperature was 97F. The purpose of this video is to illustrate how a fine mist can create some instant steam and hot water. If the flow was .25 of this, solid steam would result. Too fine of a stream and the Leidenfrost Effect would prevent proper absorption. I will do a video illustrating the effect soon. This is an alternative idea for more efficient steam production. You gain the small SPI of the hose and flash steam volume. This would need to be modified to do that. Video on that soon too I hope:-)
