Hackaday Prize Entry: Modular, Rapid Deployment Power Station

Posted on by

After a disaster hits, one obvious concern is getting everyone’s power restored. Even if the power plants are operational after something like a hurricane or earthquake, often the power lines that deliver that energy are destroyed. While the power company works to rebuild their infrastructure, [David Ngheim]’s mobile, rapid deployment power station can help get people back on their feet quickly. As a bonus, it uses renewable energy sources for power generation.

The modular power station was already tested at Burning Man, providing power to around 100 people. Using sets of 250 Watt panels, wind turbines, and scalable battery banks, …read more

Typhoon-proof Wind Turbine

Posted on by

While wind energy is rapidly increasing its market share across the world, wind turbines are not able to be constructed everywhere that they might be needed. A perfect example of this is Japan, where a traditional wind turbine would get damaged by typhoons. After the Fukushima disaster, though, one Japanese engineer committed himself to building a turbine specifically for Japan that can operate just fine within hurricane-force winds. (YouTube, embedded below.)

The “typhoon turbine” as it is known works via the Magnus effect, where a spinning object directs air around it faster on one side than on the other. This …read more

The Most Straightforward Wind Turbine

Posted on by

We can all use a little more green energy in our lives at home. So when [ahmedebeed555] — a fan of wind power — ran into durability troubles with his previous home-built turbine, he revised it to be simpler than ever to build.

Outside of the DC generator motor, the rest of the turbine is made from recycled parts: a sponge mop sans sponge, a piece from an old CD drive case acting as a rudder, the blades from a scrapped fan, and a plastic bottle to protect the motor from the elements. Attach the fan to the …read more

VR and Back Again: An XRobots Tale

Posted on by

Our friend [James Burton] from XRobots has engaged in another bit of mixed-reality magic by showing how one can seamlessly step from the virtual world into the real world, and back again. Begone, green screens and cumbersome lighting!

Now, most of what you’re seeing is really happening in post-production — for now — but the test footage is the precursor for a more integrated system down the road. As it works now, a GoPro is attached to the front of a HTC Vive headset, allowing [Burton] to record in both realities at the same time. In the VR test area …read more

Hackaday Prize Entry: Dave Thomas’ Desert Dryer

Posted on by

It seemed utter madness — people living in hot desert climates paying to heat air. At least it seemed that way to [David Thomas] before he modified his tumble dryer to take advantage of Arizona’s arid environment.

Hanging the wash out to dry is a time-honored solution, and should be a no-brainer in the desert. But hanging the wash takes a lot of human effort, your laundry comes back stiff, and if there’s a risk of dust storms ruining your laundry, we can see why people run the dryer indoors. But there’s no reason to waste further energy heating up …read more
