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!
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
