We feature a lot of off-grid power projects here at Hackaday, whether they’re a micropower harvester or something to power a whole house. Somewhere in the middle lies [esposcar90]’s 3D-printed ...

For anyone with even the slightest bit of engineering interest, wind turbines are hard to resist. Everything about them is just so awesome, in the literal sense of the word — the size of the blades, ...

Clean, portable energy generators are a terrific technology but for the most part, they’re limited in the amount of energy they can produce. At best, the average mobile energy generator yields just ...

Thanks to the development of new, lightweight rotors, engineers in Germany have created a small wind turbine that excels at ...

Led by the Advanced Structures and Composites Center (ASCC), the WIND REWIND team’s project “Blades for Large-Format Additive Manufacturing” marks a significant milestone in their mission to advance ...

Wind tunnel tests revealed that the turbine can reach up to 450 revolutions per minute and deliver a power output of 2,500 ...

The U.S. Department of Energy (DOE) has announced an award of $2,849,000 to the Composites Manufacturing Simulation Center (CMSC) of Purdue University (West Lafayette ...

Incorporating machine learning, MIT engineers have developed a way to 3D print aluminum alloys that are five times stronger.

Wind energy is a vital component of a portfolio of clean, sustainable power. Those slow-moving turbine blades you see rotating at wind farms are constructed largely manually, and low-cost labor keeps ...

(Nanowerk Spotlight) Water contains tremendous untapped energy, but very little of it is being harnessed currently. On a large scale, dams harvest hydroelectric power, while tidal and wave energy ...

Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams.

Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design ...
