Solar Water Heating Projects and Plans

Solar Water Heating Projects and Plans
Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can save as much as $7000 by building your own system. There are just over one hundred projects with full construction details listed below -- all free. The projects range from simple batch heaters for warm climates through closed loop and drain back systems that will work in any climate. One of the systems is our own $1,000 solar water heating system that has provided a solar fraction in excess of 90% through our cold Montana winter. My thanks to the people who have built systems, and then taken the time to send in pictures and descriptions for others to use.

Illustrations US Hot Springs | HSE Home Page | Build your own Hot Tub Recycle A Refrigerator Into A Solar Water Heater Related Content CD and DVD Recycling The CD Recycling Center of America announced that it has chosen the United States Postal Service as ... Design and instruction about how to recycle a refrigerator into a solar water heater. Recycle a Refrigerator Into a Solar Water Heater Everyone knows that refrigerators are good for storing cold. Ever go riding or walking through the countryside . . . and discover an old, abandoned Frigidaire, Kelvinator, or what-have-you just sitting there collecting dirt, leaves, and field mice? For a while, I felt good knowing that I was helping to clean up the countryside, and recycle tons of valuable metals (thereby reducing the need for mining). "Surely," I said to myself, "there must be some useful function that a precision-made, well insulated 'cabinet' can serve." The Solar Water Collector The "shell" of the collector was easy enough to make: All I did was nail together a 5 inch by 2 foot by 4 foot box out of scrap lumber and wood paneling. OK. Miles K.

10 Clever Architectural Creations Using Cargo Containers: Shipping Container Homes and Offices Cargo Architecture: 10 Shipping Container Homes & Offices Article by Urbanist, filed under Offices & Commercial in the Architecture category. With the green theme growing in popularity across every stretch of the world, more and more people are turning to cargo container homes for green alternatives for office, and even new home, construction. There are countless numbers of empty, unused shipping containers around the world just sitting on the shipping docks and taking up space. The reason for this is that it’s too expensive for a country to ship empty containers back to the their origin in most cases, it’s just cheaper to buy new containers from Asia. The result is an extremely high surplus of empty shipping containers that are just waiting to become someone’s home or office. There are plenty of benefits of to the so-called shipping container architecture model. The world’s first hotel built from recycled shipping containers has popped-up in Uxbridge, West London.

Basking in the Sun Heat as Something Useful In physics classes, I often catch myself repeating the mantra that heat is a disordered, useless state of energy that is generically the endpoint of an energy flow process. For example, the energy allocated to the fast-spinning wheel of an upside-down bicycle will slowly drain away as the wheel stirs the air, makes sound, and suffers friction at the bearing. Every one of these energy paths results in heat, until 100% of the invested energy is dissipated and the room is a tad warmer as a result. The asterisk is that the overwhelming majority of our societal energy consumption makes use of heat—over 90% in the U.S.! Radiant Heat The Sun transmits its energy to Earth across the emptiness of space via radiation. Summing over the area of the spherical Sun, at 109 times the radius of Earth, we find the total radiant power of the Sun to be a whopping 3.9×1026 W. Passive Solar: Putting Heat to Use Drab Winter?

$350 Solar Heated Hot Tub Search The Renewable Energy site for Do-It-Yourselfers Brian's Description: Here's some info on my project. I didn't take many pictures, but the construction is pretty basic. I framed the collector box with 2"x6" lumber and 1/4" plywood, the size is about 26" x 8'. The pump came from Lowes and is the Garden Treasures MD170 fountain pump. We are real happy with our choice of the 150 gallon Rubbermaid stock tank for our tub. I am using 3 sheets of the 3/4" blue Styrofoam for the tank cover. I did spend about $400 on this project, but did already have some of the materials. Tank $120 Pump 30 Urethane ins 90 (with shipping) sheet insulation 50 CPVC 75 I had most of the wood already, used sections of a old water hose between tank and collector, with pool noodles for insulation. I'm sure I left out some details, so feel free to ask questions. Brian And, the this note on performance from Brian: Was in the hot tub last night at 110 deg, still 106 tonight without running it today.

Solar Water Heating System Basics What is Solar Water Heating? Solar water heating collectors capture and retain heat from the sun and transfer this heat to a liquid. Solar thermal heat is trapped using the “greenhouse effect,” in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation. Two principles govern solar thermal collectors. Second, heat loss is more rapid if the temperature difference between a hot object and its environment is larger, in this case between the temperature of the collector surface and the ambient temperature. The most basic approach to solar heating of water is to simply put a tank filled with water into the sun. A more common collector is called a flat plate collector. This is quite simple, but there are some very technical factors involved in making the collector as efficient as possible. Another popular type of collector is called evacuated tube, which has a long, skinny absorber that is inside a glass tube.

One Per Cent: Grid-scale battery could keep going and going... Hal Hodson, technology reporter We need a big battery for when the sun doesn't shine (Top Photo Corporation/Rex Features) A new battery technology may pave the way for cheap, long-lived power storage that can quickly pump electricity into the grid to compensate for fluctuating renewables like wind and solar. Developed by Yi Cui and colleagues at Stanford University in California, the battery's key advantage is its electrodes, which can run for a thousand charge cycles without degrading. Battery electrodes typically degrade over time as ions in a battery cell repeatedly slam into them and are ripped away again. By coating the negatively charged cathode in copper hexacyanoferrate and using an anode made of activated carbon and a conductive polymer - compounds that allow electricity-carrying ions to move easily in and out - the team were able to build a prototype battery with electrodes that didn't lose capacity over time.

VC Confidential: Why Great Companies Get Started in the Downturns I have always been amazed by how many of our success tech stories, as well as Fortune 500 companies, started during drastic down turns. Innovation does not take a holiday, and in fact, thrives during difficult times when pain & need are greatest. While the current downturn is historic, it pails in comparison to the 22 year depression the US experienced from 1873 to 1895, triggered by the Vienna stock market crash. During this extended drought, a large number of Fortune 500's & major corporations started including Eli Lilly, IBM, Merck, Hershey's, Gillette, Alcoa, J&J, Chevron, GE, AT&T, Abbott, Lilly, Coors, Johnson Controls, Bristol-Myers and PPG to name a few. During the great depression (1929-1939), Texas Instruments, HP, 20th Century Fox and United Technologies all launched. Other periods: during the Oil shock & market crash (1973-1976) Microsoft, Genentech & Apple started.

A Homemade Solar Water Heater I've long been impressed by the simplicity of many of the homemade solar water heaters developed by MOTHER EARTH NEWS' researchers. And now I want to tell their energy-conscious readers about a solar "breadbox" device that I've come up with. My unit's absorber/storage tank was salvaged from a discarded water heater. I welded legs onto the cylinder and installed an inlet fitting to send the cold water to the bottom of the tank. Then I painted my creation with "hi-temp" flat black paint. The tank sits in a plywood box, the inside of which is generously insulated with fiberglass. My creation's only moving part is an insulated door/reflector that I open every morning and close at night (it's angled just right for catching the low-slung winter sun, making the box even more efficient in January than it is in July). The exterior surfaces are covered with durable sheet aluminum.
