Generating Power with Wind, Water, and Solar

Posted on by

It is three weeks after the apocalypse. No zombies yet. But you do need to charge your cell phone. How do you quickly make a wind turbine? If you’ve read this project, you might reach for a few empty water bottles. This educational project might not charge your phone without some extra work, but it does illustrate how to use water bottles to make a workable air scoop for turning a crank and possibly generating electricity.

That takes care of the wind and water aspects, but how did we get solar? According to the post — and we agree it …read more

Wind Turbine Pushes Limits Of Desktop 3D Printing

Posted on by

There was a time, not so long ago, when hype for desktop 3D printing as so high that it seemed you could print anything. Just imagine it, and your handy dandy magical 3D printer could manifest it into reality. But now that more people have had first hand experience with the technology, the bubble has burst. Reality has sobered us up a bit, and today we’ve got a much better idea of what can and cannot be printed on a traditional desktop 3D printer.

But that doesn’t mean we aren’t surprised from time to time. As a perfect example, take …read more

Climate models reveal that renewable energy projects in the Sahara could spark a twofold increase in local rainfall, enabling vegetation to take hold. Continue reading Wind and Solar Farms Could Make it Rain Regularly in the Sahara Desert→

Power Generation Modules Mix and Match Wind, Water, and Hand Cranks

Posted on by

What’s great about the Power Generation Modules project headed by [Cole B] is the focus on usability and modularity. The project is a system for powering and charging small devices using any number and combination of generator modules: wind turbine, hand-crank, and water turbine so far. Power management and storage is handled by a separate unit that acts as a battery bank to store the output from up to six generators at once. There’s also a separate LED lamp module, designed to be capable of being powered directly from any of the generator modules if needed.

The hand crank is …read more

Making Music with the Wind

Posted on by

[Niklas Roy] built a windmill-powered music box for his backyard, and it was so awesome all the neighbors wanted to take a picture of it. Someone even liked it so much that he stole [Niklas]’s windmill in the middle of the night. (We kind of don’t blame them, it’s a gorgeously clean build.)

In the past few weeks [Niklas] has been mass-producing 20 windmills for the KIKK Festival 2017 to be held in November in Namur, Belgium. The windmills will operate in a cluster, and all play “Für Elise” when the wind blows. However, each one is driven independently and …read more

Daisy Kite Wind Turbine: Now You Can Buy One

Posted on by

The Isle of Lewis is the largest of the Scottish Outer Hebrides, sitting in the North Atlantic off the west coast of the Scottish mainland. It is the first landfall after thousands of miles of ocean for a continuous stream of Atlantic weather systems, so as you might imagine it is a place in which there is no shortage of wind.

It is thus the perfect situation for a wind power startup, and in the aptly-named Windswept and Interesting Ltd it has one that is pushing the boundaries. Their speciality is the generation of power from spinning kites, arrays of …read more

Ask Hackaday: What Are Magnetic Gears (Good For)?

Posted on by

Magnetic gears are surprisingly unknown and used only in a few niche applications. Yet, their popularity is on the rise, and they are one of the slickest solutions for transmitting mechanical energy, converting rotational torque and RPM. Sooner or later, you’re bound to stumble upon them somewhere, so let’s check them out to see what they are and what they are good for.

What Are Magnetic Gears?

Where conventional gears use mating surfaces of mechanical interlocking teeth, magnetic gears employ alternating magnetic fields to transmit torque. For a long time, magnetic gears have only played a minor role in engineering. …read more
