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.
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://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...
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.
Lightouse fresnel lens solar collector with sun tracking. This a solar collector that uses fresnel lens and precise solar tracking. As a result it can absorb the solar radiation all the hours of the day with high efficiency. It can be used as steam generator, house heating and for warming up water for general use. It includes overheating protection, rain or snow recognition and automatic cleaning of the collector glass if needed. Also the display you see in the video shows input, output , ambient temperatures and sun power as well as the power of the collector in calories, watts or percent. These values are also stored in the memory for future evaluation. The cost of this solar collector in terms of calories produced, is much lower than the conventional solar collectors.
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 powered water distiller using fresnel lenses.
Using a large Fresnel lens and parabolic mirror to boil 5 gallons of water or wort. This is the extended version. Part 1 of a 4 part series boiling 5 gallons of water. This is a very hard task and while I could have easily boiled 1 gallon, I wanted to test the limit of the lenses. Watch all the videos, there is a lot of info. http://www.greenpowerscience.com/
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. ...
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...
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.

http://www.greenpowerscience.com/ This is the trough mirror and a Fresnel Lens set. The water was shot in with a hose to produce flash steam. Ball bearing were used as ammo. A few modifications from this learning experience and we can launch 200 yards.
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 is a part of my ongoing water desalination challenge
In 2010, I went on an extended tour of China to several solar manufacturing plants and facilities. This is a compilation of those tours. The main owners of the solar panel factories were giving me the tours. I was able to see how photovoltaic panels (PV) were manufactured as well as solar thermal panels. Here is my DIY Solar and Wind book that was published on Amazon: http://www.amazon.com/gp/product/1508454310/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=1508454310&linkCode=as2&tag=erilaysyoucha-20&linkId=URNF3DPORKY4M5YR Barnes and Noble Nook version of my DIY Solar and Wind Book: http://www.barnesandnoble.com/w/books/1121302120?ean=2940151676939&itm=1&usri=2940151676939 Many people have send me messages asking me about books or info on the panels that I used.

Hot Water Circulation is the lowest cost heating I have found to heat 1800 sq. ft. using my Gas Water Heater with a 110 gallon storage tank for both Heating, Hot Water. My Gas bill runs about 18 dollars a month in the summer and 70 in the winter and also includes gas cooking, and so far I have not had a problem running out of hot water.
This is a fun project and I hope you consider doing this easy DIY system to help your energy efficiency. In this "how to" part we will build the frame for the panel.
It's been almost a year since I installed this Solar Hot Water Heater to generate hot water for my summer shower. This video is an update covering how the unit is performing and holding-up. I also discuss some of the science behind how the unit actually works. A few months ago, we had a (weak) hurricane come through the area. Some small limbs blew off a nearby tree and fell on the unit. They caused no damage. If you are interested in installing one of these units, and have any questions, feel free to contact me via Skype. My user name is: john_by_the_creek. When you send a contact request, please reference "solar water heater".
This is an awesome little parabolic solar cooker. That it breaks down and can be stored in a small pouch makes it perfect for a tiny house. Finding the focal point is easy. I had a bit of trouble with it because the table it was sitting on is a bit un-even. You may have better luck setting it on the ground. https://www.facebook.com/thesunjuicer http://www.sunjuicer.com/
I have been working on this for years. This one will bring up water temps by 55 degrees on a sunny day. Copper would be the best long term for this unit but my budget will not allow that expense. I would love to see someone do it though. I use to sell these video's but I had a change in heart I hope Y'all enjoy

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
