Bo Andersson built a wind-powered generator just because he wanted one to use as a foundation for more experiments. When people said his idea to use a truck "rear end," or differential, to transmit wind power to a generator on the ground wouldn't work, he went ahead and put it on top of a 30-ft tower. Now Bo puts power back into the grid. And he can truly reap the wild wind.
Bo didn't listen to the nattering negative naysayers and got the job done. The reason it worked is because it's been done successfully many times and beginning years back. Differentials from old junked cars, etc. have been a convenient source for mechanical drives since the Model A. Considering he's been around a few years, Andersson may have even seen such a setup or read about one. Actually seeing or knowing firsthand something works is better than any number of people who think they know why it won't. Good for him!
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
