Generator

KAIST's device can generate electricity from bodily heat (Image: KAIST)

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a lightweight, flexible and high-efficiency thermoelectric generator that can harness your body heat to generate a small amount of electricity. The device could be used to extend the battery life of low-power wearable devices.  Read More

The three young inventors of the Pluvia system, which uses rainwater runoff to generate el...

When we complain about the rain, other people will often say "Yeah, but it's good for the plants." Well, thanks to a microturbine-based system created by three students from the Technological University of Mexico, it's now also being used to generate electricity for use in low-income homes.  Read More

The Sinewave Reactor's USB port replaces the bike's stem cap

While companies such as Dahon and Nokia already offer products that let you charge your phone with power generated while cycling, both systems do somewhat clutter up the handlebars and stem. Sinewave Cycles' new Reactor, however, is mostly integrated into the bike's existing steerer tube, keeping external hardware to a minimum.  Read More

The humidity-driven flexing of a spore-covered piece of latex rubber (right) drives the mo...

Ozgur Sahin believes that water evaporation is the largest power source in nature. In an effort to demonstrate the potential of this untapped resource, Sahin and his fellow researchers have created prototype electrical generators with rubber sheets that move in response to changes in humidity thanks to a coating of bacterial spores.  Read More

Professor J.C. Chiao and his postdoc Dr. Smitha Rao of the University of Texas at Arlington have developed a MEMS-based nickel alloy windmill so small that 10 could be mounted on a single grain of rice. Aimed at very-small-scale energy harvesting applications, these windmills could recharge batteries for smartphones, and directly power ultra-low-power electronic devices.  Read More

Big Rig provides electricity and energy to perform useful tasks – just add pedal power (Ph...

If you'd like to live off-grid but still retain access to power when you need it, then New York-based company Pedal Power might have you covered – providing you don't mind putting in the legwork, that is. The firm has launched a Kickstarter campaign for its two stationary bike-like gadgets that are claimed to produce enough electricity to run a laptop when pedaled.  Read More

The primary niche is to clip the generator to the top of existing solar panels in large ar...

Crowdfunding has come to the small wind generation field with an Indiegogo campaign intended for an interesting target niche: a small wind generator designed to be clipped onto solar panels. According to his pitch, Michael Ring has not only created a prototype, but calculated possible energy returns, targeted a price point and lined up suppliers for initial deliveries and has turned to Indeigogo to get his small startup off the launch pad.  Read More

The SunSocket uses mono-crystalline solar panels

To get the most out of solar panels they need to be facing the right way. Systems that track the sun are often used in large solar power stations and some larger home installations, but most flat panels for portable applications just lie there. Colorado-based Aspect Solar has come up with the SunSocket Solar Generator, a lightweight, portable, self-contained solar power system consisting of a battery and solar panels that brings the advantages of automatically tracking the Sun to small applications.  Read More

The current wing is an inflateable wing specially built by a kitesurfing manufacturer for ...

The University of Delft has a program devoted to kite-based generation systems, with 20 years of research and development under their belt since Wubbo Ockels, the first Dutch astronaut established it. Now, members of the team are exploring practical niches where the compromises of kite-based power might pay off. One has just completed a trip through Kenya, Tanzania and Senegal discussing opportunities for rural African kite generation with governmental agencies, universities and companies in the renewables space.  Read More

NRG's Power2Serve

One of the pressing needs in the event of a large-scale disaster or emergency is power. With Power2Serve, energy provider NRG is addressing this need head on in the form of 68 feet (21 m) of truck and trailer equipped with 40 kW of electrical generation and a Wi-Fi pavilion which people can use to communicate and keep abreast of events.  Read More
