The prolific [Peter Waldraff] is at back it with another gorgeous micro train layout. This time, there are no plugs and no batteries. And although it’s crank-powered, it can run …read more Continue reading Crank-Powered Train Uses No Batteries or Plugs
Scoring an interesting bit of old gear on the second-hand market is always a bit of a thrill — right up to the point where you realize the previous owner …read more Continue reading Generator Control Panel Unlocked with Reverse Engineering Heroics
If you live somewhere prone to power outages, you might have thought about buying a generator. The problem is that small generators are cheap but — well — small. Big …read more Continue reading That’s not a Junker… That’s My Generator
Here in the West, power going out is an unusual event. But in more remote regions like the Himalayas, reliable electricity isn’t a given. A group of local craftspeople, researchers, …read more Continue reading Open Source Waterwheel
Collecting energy from various small mechanical processes has always been something that’s been technically possible, but never done on a large scale due to issues with cost and scalability. It’s …read more Continue reading Harvesting Mechanical Energy from Falling Rain
With a slogan like “The Future is Ecclectic,” we’d expect some interesting things from INNengine, a startup based in Spain. The company is showcasing a “one-stroke” engine that works as an opposed piston with a wavy twist.Continue ReadingCategory: Auto… Continue reading INNengine “one-stroke” waves away conventional engine design
A thermoelectric generator (TEG) can turn a temperature difference into electricity, and while temperature differentials abound in our environment, it’s been difficult to harness them into generate practical and stable …read more Continue reading Passively Generating Power Day and Night Takes The Right Parts
Although many groups are developing power-generating “smart fabrics,” the technology is often too complex to be scaled up to commercial use. Now, however, scientists have devised a simple method of embroidering electrical generators onto regular fabric… Continue reading Embroidered patches allow existing fabrics to generate electricity
With an ability to turn friction into small amounts of electricity, triboelectric generators may one day be used in clothes that turn movement into power, in battery-free brain implants, and a host of other scenarios. Scientists working on cheap and ea… Continue reading Simpler, cheaper electrical generator can be made with store-bought tape
Harvesting energy from the wind has been a commercially viable way of generating clean energy for around three decades now. Wind turbines are a reliable, proven technology but they do …read more Continue reading Go Fly a Kite
