Hydroelectric generators produce electricity by harnessing the force of running water. This may seem like a novelty or impractical for home use, but you’d be surprised.

Looking to harness the power of water right at home? In this comprehensive video, we'll guide you step-by-step on how to make ...

But, you'd get more power faster, sooner, by simply hand cranking a small generator. A treadle-powered device would cost less, and charge faster, and weigh less in a backpack than this 'gizmo ...

A hydroelectric generator is small enough to be carried as a backpack and weighs less than 30 lb.

There are already plenty of gadgets that allow people to charge their mobile devices while off the grid. Most of those products utilize solar power, while a few have gone the thermoelectric route.

Siphons are one of those physics phenomena that, like gyroscopes, non-Newtonian fluids, and electricity, seem almost magical. Thanks to atmospheric pressure, simply filling a tube with liquid and p… ...
