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 ...

Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces ...

Harnessing a principle known as triboelectrification, researchers have worked out the optimal way to generate an electrical charge in a relatively simple way. The breakthrough could provide a ...

Power outages are a huge pain, and can seriously disrupt your life. Stop worrying about what will happen to the food in your fridge or your pipes in the winter should you lose power, and invest in a ...
