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!
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
