This article outlines how to build a low-cost solar panel to heat water. It uses components normally available from glazing companies, home improvement and car parts shops.

Steps

1. Get a double-glazed unit for the sunlight to pass through. Glaziers and window manufacturers sometimes have scrap units for patio doors or large windows that can be bought very cheaply. Glass with a low-emissivity coating such as Pilkington K glass is ideal.
2. Get a single-panel room radiator that is slightly smaller than the glass unit. Scrap yards sometimes have old radiators, or ask a plumber who is refurbishing a central heating system.
3. Build a strong wooden box to fit the double-glazed unit. Use 12mm plywood for the back and 150mm x 50mm timber for the sides. Make sure it is deep enough to accommodate 50mm of insulation plus the radiator. The glass should exactly fit the box on three sides but overhang the box on the fourth side so that rain water will drip off the glass when the box is set at an angle.
4. If the box will sit on a flat surface build a support so that the box can be installed perpendicular to the sun. In the UK an angle of 35º from horizontal works well.
5. Treat the outside of the box to make the wood water resistant.
6. Glue aluminum kitchen foil to the plywood inside the box.
7. Screw two radiator brackets inside the box to support the radiator.
8. Insert a layer of 50mm thermal insulation slabs over the kitchen foil.
9. Fit the radiator onto the brackets and drill 20mm holes in the side of the box where the pipes will come out. You can route one pipe inside the box to make both pipes exit the same side of the box if your installation requires it.
10. Plumb in the radiator so that two pieces of 15mm copper tube extends 100mm from the outside of the box. Use threaded straight connectors rather than radiator valves to fit pipes that go straight out of the box.
11. Spray the front of the radiator matt black using heat resistant paint, such as that used for spraying the radiant parts of coal and gas fires.
12. Screw two angle brackets onto the bottom edge of the box and bend them up to stop the glass sliding off the box.
13. Run a bead of silicone sealant around the edge of the box and place lengths of electrical tape over the bead so the glass doesn’t stick to it.
14. Place the glass on the box and leave the silicon to set. This will create an airtight seal between the glass and the box and increase the thermal insulation.
15. Screw L section UPVC strips to the three sides where the glass is flush with the box to prevent rain ingress. 45º mitres on the two corner joints makes a smart finish.
16. Get rubber engine hose with an internal diameter of 15mm from a car parts shop and attach it to the 15mm copper tube with jubilee clips. If your hose is slightly too big solder straight connectors onto the ends of the tubes to increase their diameter.
17. Finished. You now have a solar panel ready to heat water. In order to have a functioning system you will also need a water tank, a water pump and (if the pump does not run on mains electricity) a photovoltaic panel and control unit to power the pump.

Learn To Build Wind Turbines

How would you react if your neighbor told you she was going to build wind turbines? Pretty impressed? The truth is that it is not difficult to build wind turbines and many homeowners are taking the challenge to build their own wind turbines as a cost-effective means to utilizing renewable energies. It isn’t exactly snap-your-fingers easy to build wind turbines either, but with the proper plans and a motivated builder you can be building wind turbines in no time.

It is definitely your best bet, before setting out to build wind turbines, to purchase an instruction manual or guide to follow. Remember that you get what you pay for when it comes to instructions. Make sure you find a manual that is easy to read with detailed instructions. There are also many online resources and forums to help guide you through your wind turbine building process.

To familiarize yourself with the basics, before you get started on your project to build wind turbines, there are four basic components to wind turbines. To build wind turbines you must be familiar with the towers, the batteries, the turbines and the tail and propeller assembly. The tools generally required to build wind turbines are simple as well, you will need wrenches, a saw and a drill. There may also be a need for additional tools depending on how of the wind turbine you will be building yourself.

One part that you will probably be ordering when you decide to build wind turbines is the motor. The motors on wind turbines do require regular maintenance and oiling for continued efficiency, but this is a small price to pay for the excellent energy these systems provide. In addition to the motor, you are definitely going to need a good-sized workspace. Depending on your target energy output, your propellers or blades could get up to 8 feet in diameter (4 ft blades).

It takes a little work to build wind turbines, but there is really nothing overly complicated about the process and generally the process can be fairly inexpensive once you are operational and your electric bills are dropping each month. Building wind turbines is also a fast growing occupation worldwide as technicians are tough to find. So learn how to build wind turbines for yourself and take advantage of the opportunities free electricity and know how can provide.

Find out just how easy it really is. Yes you can do it, a great family project. Just click the following link to the wind generator plans. You will get the Wind Generator book at the low price of only $19.97.
