DIY (Do it Yourself) Projects — Solar Photovoltaic Panel Projects

Photovoltaic cells (PVs) are a very different technology from solar water heating, and use light to generate electricity. They are particularly well suited to sites where a grid connection would be difficult or expensive or that are only used in the summer. For an independent power supply, solar works well with wind as there is a good balance of both over the year. Solar electricity, like electricity from other renewable energy sources, doesn’t produce carbon dioxide or harm the environment.

Although start-up costs are higher than other renewable technologies, PVs have key advantages:

  • there are no moving parts to fix so they are relatively easy to install and maintain
  • they can be sited in urban areas and are not restricted in the way that wind and hydro-power systems are
  • they can replace other roofing materials, for example tiles. The cells are embedded in a flat, waterproof material to form ‘modules’, which make ideal cladding material for walls and roofs
  • they need not take up any additional land space.

How Do Solar Hot Water Heaters Work?

 With the rising cost of fuel and concern over carbon footprints, many homeowners are turning to green technologies such as a solar water heater. These hot water heating systems not only lower your fuel costs over the lifetime of the system but will also help the environment by cutting back on harmful carbon emissions. Developing a set of workable solar hot water heater plans could be your first important step toward leading a “greener” lifestyle.

Basics

The U.S. Department of Energy provides a complete breakdown of the basics of solar hot water heater systems. As they explain, there are basically two types of solar hot water heaters: active systems, which contain circulating pumps and controls, or the passive systems, which don’t. Both of these plans will require solar panel collectors and storage tanks for the water.

The solar storage tanks will need to be well-insulated to lock in the heat and keep out the cold. You could opt for a two-tank storage, where your system would preheat the water before it enters your conventional water heater. Or you could decide on the single-tank storage option, which combines the back-up heater with solar storage within the same tank.

Getting Started Making Biodiesel

Getting Started Making Biodiesel
by Graydon Blair

Welcome to the wonderful world of Biodiesel. It is a fun and rewarding hobby in which you can make your own fuel to run in diesel engines.

Biodiesel is most commonly made by chemically altering an organic oil through the use of a catalyst and an alcohol, typically Methanol. The chemical reaction that occurs through this process breaks down the oil molecules and replaces the glycerine portion of the molecule with an alcohol molecule. The glycerine falls to the bottom and is drained off resulting in Biodiesel.

The Biodiesel is then typically washed, to remove any extra impurities and is then used as a fuel in a diesel engine without making any modifications to the engine.

Biodiesel is known chemically as a ‘fatty acid methyl ester’. Which is just a fancy way of saying it’s a product made from Methanol and an organic oil with fatty acid chains in it. It is easily made and has many benefits, including environmentally friendlier tailpipe emissions and improved engine performance.

To get started making Biodiesel, there’s a few things you need to know.

DIY (Do it Yourself) Projects — Solar Cooking

Successful solar cookers were reported in Europe and India as early as the 18th century.  The increased use of glass during that period helped inventors to trap heat & hot air.  In 1870, Augustine Mouchot invented a fairly portable oven for the French Foreign Legion.  It could bake a pound of bread in 45 minutes or 2 pounds of potatoes in one hour.

Around the same time, W. A. Adams developed an eight-sided mirrored oven which reflected light through a glass cone located in the center of the oven.  This oven could cook a 12 pound turkey in 4 to 5 hours.  This is still a popular design today.  We actually use a large model, very similar to Adam’s oven.  In this oven we can cook 60 pounds of food at a time

From The Sun, To The Outlet:  You can have as many panels as you want, but until you have the right electronics, the power created could be useless. The power you are creating has to be stored, or at night time you will have no power. For this we use batteries. Not just your everyday AA batteries though, we need what is called a deep cycle battery. Deep cycle batteries are made to be discharged, and charged back up, many many times. If you did that with a normal car battery, it would not live very long. Deep cycles are use in boats for trolling, in golf carts, and even in some forklifts. If you like to scrounge, ask around your forklift dealers, and certain manufactures(they all use forklifts) for the ones they thow out. Golf courses can be good as well.

How To Make A Solar Power Generator For Less Than $300 – Fearsome Homepage:  Using parts easily available from your local stores, you can make a small solar power generator for $250 to $300. Great for power failures and life outside the power grid. Power your computer, modem, vcr, tv, cameras, lights, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your highrise. I keep mine in my bedroom where it powers my cd player, turntable, lights, modem, laptop, and (ahem) a back massager. I run a line out the window to an 8" x 24" panel on the roof.
