http://greenpowerscience.com/ A large Fresnel Lens (moderate Fresnel groove) solar focused on a copper lens tube with a 12 V pump (powered by two 6 watt solar panels) with water circulating through the unit. Water, seven gallons, was raised from 63 F to 106 F in one hour. It is not super efficient as heat is lost at the open top of the glass tank. This is designed to illustrate one method of solar heating a swilling pool with a Large Fresnel Lens. TESTING HDD AQUA BLOCK.
http://pipetalk.stores.yahoo.net/ PIPEtalk Industrial Pipe Estimating shows how to heat your pool. So many of you have asked why can't we use a magnifier glass to heat the pool water. As normal, PIPEtalk continues to think outside the box. Here is a method using 1-1/2” PVC pipe, aluminum plate/angle, threaded rods, four large linear Fresnel lens, a single direction sun tracker, a timer, battery and solar battery charging system. The system would be more efficient with metal pipe. Now we answer the compelling question, "how can I use a magnifying glass to heat the pool" for you! Each "hot spot" is 210 degrees. The result is about a half-degree rise in the water temperature (5300 Gal) over an eight-hour day using a one HP pump. Valves slow the water flow rate through the solar system...
This Lens is one of my giant solar Fresnel Lens in my personal collection. It is a spot lens measuring 1.4732m x 1.143m and has a 1500mm focal length. http://greenpowerscience.com/ This lens delivers 1.6 sq m of concentrated sunlight to a 25mm area. We are developing a quad section version of a lens slightly larger than this one.
http://www.homemadepowerplant.com/?hop=adonpub Charls Shults illustrates how he is able to generate six kilowatts of solar energy at a fraction of the cost of current photovoltaic solar panel systems. With his system, you are able to supply your home with electrical power and hot water for about $6,000 instead of the $50,000 plus for a conventional photovoltaic solar panel electric system, which he states is the norm.
Solar scorcher that I finished building. Fresnel lens came from a free, 50" Toshiba rear projection TV. Framed up with 2x2, but I still need to build an adjustable table in order to place things within focus of the lens, or near focus, depending on the application. If you want your comments to remain, do not use foul language. I remove comments with foul language, whether your comments intentions are good or bad.
This solar water lens that is almost 30 inches in diameter is grid free energy and can burn through wood quickly. It delivers a very large powerful focal point that is only useful around noon in the summertime when the sun is directly overhead. The material is crystal clear vinyl shower curtain. This lens concentrates about 500 watts of solar heat energy to a focal point of 1 inch optimal with a 3-6 inch scatter.

Solar Fresnel Lens and a Tevana Tea vacuum container + steel wool nanoparticles. Superheated http://www.greenpowerscience.com/ steel wool creates nanoparticle surface structure. The steel wool has a vast surface area, when superheated dry, the smooth shiny surface structure opens up creating structural crevices less than 100 nanometers that act as nanoparticles. Any previously mirrored metallic object that is dulled with heat alone has this micro structure. This is different than sanding. The direct contact with the aqueous solution allows for optimal heat transfer from the heated metal surface to the water. Steel wool is a good choice over mud bath nanoparticle suspensions as the skeletal structure allows for enhanced area coverage in 3 dimension vs that of a 2 dimensional mud bath. G...

Fresnel Lens solar water filtration systems offer an off grid option to clean water This solar distiller can deliver .5 GPH The Fresnel lens concentrates sunlight to a common focal point that creates a steam boiler allowing for rapid distillation with the sun. http://greenpowerscience.com/ If you are concerned, add 10mg Na to each liter. Also, eating food with water, all minerals are mixed with fluid in the stomach converting distilled water into mineral water. Distilled water is not magic, if you add a splash of milk to tea made with distilled water, you now have 10x the calcium of regular mineral water. http://www.eves-best.com/distilled-water-myths.htm Distilled water is very good for you. The only areas it may cause a problem is developing nations that have near famine conditions. ...
Finally! A working mini solar tower powered by a fresnel lens that turns a turbine, a paper turbine. It's nowhere near powerful enough to turn a PC fan. This one is built like a screen/matrix solar air heater and isn't much like a solar tower like the 5 previous versions. I'm using my fresnel lens and mirror solar cooker setup for the structure. Watch my "Where I use Math" video to see the chimney formula I used for this project: http://youtu.be/l6YGoN689qs Version 7 was the final version and was able to turn a paper turbine and got a boost from an actual tower, but did not generate electricity.

I state that I have stuff for sale on ebay and you can see all those items at http://search.ebay.com/_W0QQsassZaltonfilmguy1QQhtZ-1 or by following the ebay links on my main website www.NickBrianWalters.com My Vlog with updates on new uses for the setup. This time I'm heating up water for a bath with the giant fresnel lens. I also state that my black/mint tea came out great, that I'm furthering my work in the garden, and other tips and such.
This was starting to boil, my tripod was on uneven grounds and decided to take a hot bath. I will try it again! OOOPPS!
Heating a swimming pool with Fresnel Lenses is possible but simply pointing one at clear water does nothing. A dark target is required to absorb the concentrated sunlight. Fresnel Lenses do not amplify light, they concentrate light. An obstructions blocking the path of natural sunlight light a lens simply redirects light from a larger area to a smaller area. The better option is to sink large dark objects to the bottom of your pool where sunlight can expose the dark object. Square area is square area so a one meter square Fresnel Lens concentrated to a dark target in a swimming pool will collect the same amount of solar energy as a one meter square black sheet of plastic or metal. Since the objects are submerged, metal and plastic are equally as effective due to equal surface area in an aq...
This simple experiment illustrates the intersection between optics and thermodynamics.
The large fresnel Lens is used to distill water and DESALINATION of seawater. What Happens When You Boil large volumes, it is less effective than smaller batches. This is Part 4. BOILING 5 gallons is very hard to DO. I WANT TO ALSO USE THIS TO BOIL WORT IN THE FUTURE http://www.greenpowerscience.com/
Fresnel Lense Project - 5 Paralel Lense (PART 1) This project is using 5 fresnel lenses in paralel, for the purpose of using mirrors to bounce the magnified light energy into a single location to power a larger solar stirling engine, or for the immidiate result of steam generation to power a steam engine that will be outfitted with an electrical generator. The goal of this project is to produce 500 continuos watts of elecricity while the sun is out. Next step, is to get the steel pipe mounted and fitted, so water can be turned into steam.

Here I supervise my son as he starts a fire using the basic materials we've gathered into our PSK ( personal / pocket survival kit ). This is NOT an Instructional, Tutorial, or How-To video but is for entertainment purposes only. He used a magnifying lens (not glass but 4x acrylic fresnel type), jute, scrap wood tinder, and vaseline (petroleum jelly). Things learned: 1) Preferebly don't start a fire right next to a bundle of leaves. 2) Blow horizontally away from you instead of straight down if possible. 3) Position yourself so that the wind is blowing from behind or from your side (you are at the mercy of the direction of the sun however).
Let the water drops fall down upon your chest
and carry away with them all your stress.
Let the steam begin to rise and fill this room
with the intoxicating smell of your perfume.
I will touch your neck, kiss your shoulders,
assure you that this is not over.
I will hold you close and put your lips to mine.
As long as there’s hot water baby
this is what we’re doing with tonight.
The flicker of the candlelight reflects it all:
one shadow of us dancing on the wall.
Don’t hold back baby just hold on, and feel my arms
