A wind turbine is a very simple machine: how to build it. And how to convert a bike to electric - GT Aggressor 1.0 part 1 and GT Avalanche 2.0 part 2

We are looking for permanent photovoltaic cells suppliers.

Solar photovoltaic (PV) systems.

Today there are three forms of commercially available solar cells - monocrystalline, polycrystalline and thin-film. Each of these technologies has its benefits and demonstrated strengths. Due to their higher efficiency and longer useful life monocrystalline cells have been the technology most favoured by industry, however, the trend and future seems to lie with thin-film which typically has demonstrated lower cost per watt, cell efficiencies and life expectancy.

Wind energy systems.

The wind is a renewable energy source, continuously generated or replenished by the forces of nature. Renewable energy technologies, such as wind energy systems and solar photovoltaic (PV) systems, which use sunlight, convert renewable resources into usable forms of energy that can complement or replace conventional energy sources.
Wind is very complex process, which can be described very simply.
The sun heats the earth at different rates depending on weather an area is below clouds, in direct sunlight, or covered with water. The air above the warmer areas heats up, becomes less dense, and rises. The rising air creates a low-pressure area. Cooler air from adjacent higher-pressure areas moves to the low-pressure areas. This air movement is wind.

					Designed and manufactured by Li-ion battery experts at Tenergy Corporation, the battery packs and modules offered here are pre-wired and configurated with protective circuit board (PCB). These battery packs are ideal for use right away or for making battery packs by connecting them in parallel or in serial for higher capacity or voltage.
					Better performance in driving electronics and huge money saving are the two major reasons to buy NiMH (Nickel metal Hydride) rechargeable batteries. They can be charged up to 500-1000 times and last longer than alkaline or NiCd batteries.
					We are offering a wide selection of Tenergy Brand high capacity NiCd rechargeable batteries. We provide these batteries to you at great saving opportunities. The volume discount tables listed in each cell.
					Extraordinary Long Cycle Life -Best can up to 2000 cycle life, would be over 8 times life of Lead Acid and 3-4 times of Li-ion. Wide working temperature range —From -4 F to 150 F (-20 C–+70C) Extremely cold and extremely hot weather will not effect its performance. Flexible Form Factor - Small in size and light in weight 1/3 weight of Lead Acid and 65% weight of NIMH. No memory effect.
					We are offering a rich selection of chargers for rechargeable batteries and packs. Categorized below are chargers for NIMH and NICD single cells (AA, AAA, C, D, 9V); NIMH and NICD battery packs (2.4V to 60V); Li-ion and Li-Polymer batteries and packs; and RCR123A batteries. Please selected the category to choose the right chargers for you.

Permanent Rare Earth NdFeB magnets (for rotors, motors, generators, alternators, or custom built wind turbines).

A wide and growing variety of strong Neodymium Magnets in stock and ready to ship. These are strong magnets in a nickel-plated steel casing that allows the magnets to be easily installed into a generator of a small wind turbine project or hydro power station’s rotor. The shapes in the stock include discs, cylinders, blocks, cubes, spheres, rings, cones, pyramids, triangles, stars. One style of magnets comes with a hook attached, which can be incredibly handy on your fridge, in your locker, garage or shop.

Neodymium Magnet Safety

The neodymium magnets are extremely strong, and must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Neodymium magnets are brittle, and can peel, crack or shatter if allowed to slam together. Eye protection should be worn when handling these magnets, because shattering magnets can launch pieces at great speeds.
