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.

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.

Go to Sidebar 1, Maintain Temperature Stratification in Your Tank Go to Sidebar 2, Rust Never Sleeps: Open Loop vs. Closed Loop Hot water represents the second largest energy consumer in American households. An investment in a solar water heating system will beat the stock market any day, any decade, risk free. In this article I'm going to cover the most common options for solar water heating, basic principles of operation, and some historical perspective on what has worked and what has not. Below: A Typical Solar Flat Plate Water Heater. A Checkered Past, A Bright Future Solar thermal's past is a good example of why everyone should be skeptical of government involvement in energy. The intention was to stimulate sales for solar thermal systems. The solar thermal industry has been purged of the tax credit telemarketers and overnight experts. Turn the thermostat down. Caution!

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.

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.

Plans For Various Passive Solar Heaters The Do It Yourself Passive Solar Window Heater How To Make A Passive Solar Heater. This is a very simple and inexpensive project. There are many passive solar heating projects out there, but we must admit, we were very sceptical at first. In the cold November mornings, what help can a simple bit of styrofoam and aluminum foil really provide? So we decided to make one and see how well it works. How this works: When the sun shines, the black painted area will absorb the heat from the suns rays. Make your own passive solar window heater Paint your solar heater black Homemade passive solar window heater in action In the photos above you can see the homemade passive solar window heater. First choose a south facing window and measure the window frame and decide if you want to cover the window completely or not with your solar heater. Cover the backing with aluminum foil on one side. Take the whole thing outside on a warm day and spray paint it all black. Pros and cons of this design.

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.

7 Solar Water Heating System Designs by Michael Hackleman (Rob Harlan is a general and solar contractor with 25 years of experience with solar water heating systems in Mendocino County, California. Rob primarily designs and installs photovoltaic systems today.) MH: Rob, will you give a brief history of the last 30 years of solar-water heating system design and implementation? Rob: Solar-water heating systems got a real boost in the 1970s when tax credits were offered by state and federal programs to help folks make the investment. These systems were intended primarily for domestic hot water, i.e., showers, dishwashing, cooking, and clotheswashing. They were also popular for heating the water in pools and hot tubs. MH: As I recall, a lot of manufacturers also disappeared when the tax credits went away. Rob: Some designs were indeed flawed—poorly implemented, overly complex, or incorporating untested ideas. Rob: And—on active systems, a controller turns a pump on and off as solar heat is available. Rob: Freezing protection. Rob: True. 1. 2. 3.
