The blade is cut from a single piece of 3.5″ (90mm) PVC pipe, with another piece of smaller-diameter pipe serving as the body of the turbine.

The generator itself is a small stepper motor which can be pulled from a floppy disk drive or a scanner. You only need a few parts to make this happen, and chances are you have them sitting in your junk bin already. You can see two AA batteries hanging off the side of this small generator. Hit your parts bin and set aside an afternoon to build a wind turbine that recharges batteries. Posted in green hacks Tagged generator, sustainability hacks, Wind turbine Sustainability Hack: Wind Turbine Battery Charger A great build that harkens back to this awesome webpage about turbine building and living off the grid. The Tech Junkies’ build produces 10 Watts of power but they’re looking to increase that to 500 W with the appropriate gearing. An aluminum hub was fabricated and the whole shebang was put on top of a found steel frame. The team found a wealth of info on blade design on this site and following a few guidelines made six blades out of 8″ diameter PVC pipe. The team connected an inverter (it’s always cool seeing a power meter run backwards) and started fabricating the blades. With a little bit of calculations, they realized they needed about 1000 RPM to get 20 Volts out of the motor. After measuring the voltage output when the motor was connected to a lathe, they discovered the power output was very linear. In the interests of sustainability, The Tech Junkies found an old 1.5 HP DC treadmill motor. The Tech Junkies put up a build log of a wind turbine that ended up being a very easy build. Wind power doesn’t require a semiconductor fab lab (unlike solar panels) and doesn’t have very many environmental consequences (unlike hydro power). With a little bit of thought put into the build, a wind turbine generator can be one of the greenest ways to generate electricity.
The video after the break does a good job of explaining the “blue barrel” construction process, but if you’d rather just see this in action, fast forward to 5:25.Ĭontinue reading “Make A Wind Turbine From 55 Gallon Drums” → Posted in green hacks Tagged clean energy, power generation, vertical axis wind turbine, Wind turbine Sustainability Hacks: Wind Turbine Generator If large blue barrels aren’t your thing, the post also features several other turbine designs, including one made with wood and aluminium foil, and one constructed out of PVC pipe. The tools required to make one of these are relatively simple, so this could make this experiment accessible to those without a vast arsenal of equipment. Although the spouse approval factor of any of these designs is debatable, at $100, the 55 gallon drum design could provide a very good return on investment. Posted in green hacks, Solar Hacks Tagged Wind turbine, windmill Make A Wind Turbine From 55 Gallon DrumsĪlthough there are several vertical axis wind turbines listed on greenterrafirma’s page, the one built with 55 gallon drums was especially interesting to us. 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. Green hacks implement one of two philosophies.
