Nanotechnology is quietly rewriting the rules of how small machines get their power, turning the ambient vibrations, motion and even humidity around us into usable electricity. Instead of stuffing ...

A hydroelectric generator produces electricity by harnessing the kinetic energy of running water. Now you can not only find stationary larger-scale hydroelectric generators but also portable micro ...

Japan’s Ricoh has designed a micro hydropower system for sewage plants that could potentially be used in combination with ground-mounted solar or floating PV. The system features a sustainable water ...

A tiny generator a centimetre across and three millimetres high has produced more than a watt of electricity, enough to power a cellphone. The experimental device, created by researchers at the ...

Researchers at the University of Texas at Arlington have designed a miniscule wind turbines with a micro-generator that can be used to recharge mobile devices. Smitha Rao, a university research ...

Access to an RF signal generator can sometimes be a little tricky for electronic enthusiasts and developers due to the cost implications. ERA Instruments is hoping to change this with the launch of ...

A new digital wristwatch called the Sparc MGS has been created by Ventura Watches which uses its own built-in motion micro-generator to provide it with the all power it needs to run its LCD display.
