Collaborate Disseminate
There are plenty of rocket experimenters toying with various liquid-fueled contraptions at the moment, and [Sciencish] is one of them. He grew tired of using air-pressurized fuel delivery systems in …read more Continue reading 3D Printed Turbo Pump Hopes to Propel Rockets To The Sky
Wind turbines are a fantastic, cheap, renewable source of energy. However, nothing lasts forever, and over time, the blades of wind turbines fatigue and must be replaced. This then raises …read more Continue reading Can We Repurpose Old Wind Turbine Blades?
After spending 18 months building an entirely new form of flight control software, California’s Jetpack Aviation has completed flight testing on its first prototype of the Speeder, a jet turbine-powered flying motorcycle. Top speeds on the final versio… Continue reading Jetpack Aviation’s flying motorcycle prototype aces first tests
Wind energy isn’t quite as common of an alternative energy source as solar, at least for small installations. It’s usually much easier just to throw a few panels and a …read more Continue reading Full Size 3D-Printed Wind Turbine
Denmark’s Vestas is looking to become an industry leader in offshore wind, and has introduced the V236-15.0 MW turbine to take the fight to GE. The new design’s blades offer the largest swept area in the world.Continue ReadingCategory: Energy, ScienceT… Continue reading Vestas reveals offshore turbine with world’s largest sweep
It’s really beginning to feel as though the problem of climate change is a huge boulder rolling down a steep hill, and we have the Sisyphean task of trying to reverse it. While we definitely need to switch as much of the planet over to clean, green energy as soon …read more

Imagine traveling back in time about 2,200 years, to when nothing moves faster than the speed at which muscle or wind can move it. Think about how mind-shattering it would have been to see something like Hero’s Engine, the first known example of a steam turbine. To see a sphere …read more

When you think of renewable energy, what comes to mind? We’d venture to guess that wind and solar are probably near the top of the list. And yes, wind and solar are great as long as the winds are favorable and the sun is shining. But what about all those …read more

There’s more than one way to light up a strip of LEDs. Have you tried building your own hydroelectric power plant to do it? Well, now you can. Replicating [Matic Markovič]’s entry into the 2020 Hackaday Prize is bound to teach you something, if not many things, about the way …read more

We’ve all got a pretty good mental image of the traditional wind-powered generator: essentially a big propeller on a stick. Some might also be familiar with vertical wind turbines, which can operate no matter which way the wind is blowing. In either case, they use some form of rotating structure …read more
