DIY vertical axis wind turbine

DIY vertical axis wind turbine
This vertical axis wind turbine (VAWT) uses five 3” PVC pipes cut in half for blades rotating on three kids bicycle wheels to spin an Ametek 38 volt motor or a wind blue alternator. The whole thing spins in a frame that is a 12 feet high and 2 foot square box that is able to sit on his deck. In total it cost him about $125 plus time, a bit more if you use the wind blue alternator. Video of the vertical turbine in action after the break.

How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. Gold Recovery Wait don’t throw those old electronics in the garbage, there’s gold in them there things. How about putting it in your pockets instead of someone else’s pocket? Laptops, phones, cameras, and the like are filled with gold plated circuit boards even printers and scanners have gold, silver, and copper, even platinum in them. Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities.

Wind Power Generators Annual Output (KWH/year) = 0.01328 (D^2) (V^3) source... Where D^2 is the blade diameter in feet squared, and V^3 is the wind velocity cubed in mph -- this is the year round average wind speed -- see wind maps below. So, a 10 ft diameter wind turbine in 12 mph average winds might produce about (0.01328)(10^2)(12^3) = 2300 KWH/year Note that the energy produced is proportional to the cube of wind speed -- having enough average wind speed is everything in wind turbines. Use the wind maps discussed below and a wind survey of your site to determine if a wind turbine will actually payoff. The graph is of the wind energy equation shown above for various wind speeds and turbine blade diameters

DIY 360 Degree SODAR Device First off, why did we decide to call this thing SODAR? SOnic Detection and Ranging, or SODAR, is a lot like SONAR and RADAR. However, we don't feel comfortable calling it SONAR because we have no desire to use it for navigation and we aren't under water. Also, it's definitely not RADAR as we are using ultrasonic pulses, not radio waves to find objects. With the technicalities out of the way, here are the project's objectives: 1) To create a freely rotatable SODAR system that can continuously detect objects 2) To create a UI that displays objects similarly to radar 3) To make it as portable as possible To accomplish objective #1, we need a way to prevent wires from tangling while the motor spins.

Make a Wind Generator Make: Projects With a motor and some piping, it’s easy to enjoy free energy forever. There are no limits to what you can do with wind power. It’s abundant, clean, cheap, and easy to harness. Solder smoke air filter I know how to solder. I've been avoiding it as much as possible for a long time due to the really crappy soldering iron I've had. As an early Christmas preset, my fiance bought me an Aoyue 937+ solder station. There are better but it's been the best solder station I've ever used. So I've gotten back in to soldering things rather than just twisting and clamping wires or using solderless breadboards.
