Although there are several vertical axis wind turbines listed on greenterrafirma’s page, the one built with 55 gallon drums was especially interesting to us.  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.  The tools required to [...]

With a little bit of thought put into the build, a wind turbine generator can be one of the greenest ways to generate electricity. Wind power doesn’t require a semiconductor fab lab (unlike solar panels) and doesn’t have very many environmental consequences (unlike hydro power). The Tech Junkies put up a build log of a [...]

Hit your parts bin and set aside an afternoon to build a wind turbine that recharges batteries. You can see two AA batteries hanging off the side of this small generator. You only need a few parts to make this happen, and chances are you have them sitting in your junk bin already. The generator [...]

Instructables user [Dustyn] recently constructed a wind-based lantern to provide a bit of free, renewable light in urban settings. The project is based around a vertical-axis wind turbine, which she says are better suited to these environments since wind often comes from all different directions. Despite their lower efficiency compared their horizontal-axis brethren, this style [...]

You can build a copy of this vertical wind turbine in a weekend and it won’t cost you all that much. Applied Sciences developed the hardware and they’re sharing all for the build details. You will be taken through every part of the build starting with the fin assembly which is made from stove-pipe material. [...]

Feeling brave and ready to strap on this jet pack? Well, that’s not all of it. What you see above is just the manifold with two nozzles that can be aimed for control. The gas turbine engine that is being designed for the project will attach to the large circular coupling on top. The finished [...]
