![]() ![]() ![]() Not enough to power a house by any means, but more than enough to charge a cellphone or run a laptop for a few hours out in the back country. With a custom fiberglass spinner, whipped up a very attractive power station that is able to provide about 20 watts in normal conditions and 600 watts when it’s very windy. At high speeds, the generator can produce 80 Volts, so a charge controller – even one based on a 555 chip – was an excellent addition.įor the other miscellaneous mechanical parts of the build, cut the blades of the windmill out of 200 mm PVC pipe and sanded them down a bit for a better aerodynamic profile. The generator for the windmill is based on a Fisher and Paykel direct drive usually found in clothes washing machines, rewired to provide 12 Volts at low RPM. obviously took the latter choice, building a windmill out of an old washing machine motor and a few bits of PVC. The other side of this coin creates green power out of junk. The first is über-technical, with very expensive, high-quality components. With the increase of 3D printer sizes and precision and the variety of printable materials we foresee a future with more renewable energy solutions you can make at home.Green hacks implement one of two philosophies. ![]() Also do keep in mind that you will need a battery to store the electricity and some kind of rectifier / control electronics (both are easily available and simple to build). You will not be able to power your house due to physical limitations and scalability but you could use it in education, to power DIY projects like stand-alone sensors, remote WiFi hotspots or charge your mobile phone in off-grid house. , while all the STL files can be found at: įor what purposes could you use a setup like this? As always you are limited with your imagination. The energy is generated like this: the wind causes the belt to vibrate in a frame that has magnets attached to it that oscillate between copper coils.Ī detailed guide for making a windbelt generator can be found at: It produces far less energy but it is simple and functions under a variety of wind conditions. One of many tutorials can be found here: Īn easier to make alternative to the wind turbine solutions as described above comes in the form of a ribbon generator. If you don’t want to print a turbine, you can make simple HAWT blades with PVC pipes. For a full tutorial on how to make this wind turbine take a look at: AirEnergy 3d printed VAWT wind turbine. ![]()
