Energy from rubbish to power Addis Ababa

Posted on Thursday, February 22nd, 2018 by

Rapidly increasing urbanisation in Africa means two things: more waste and greater demand for electricity. In Ethiopia’s capital, Addis Ababa, a new waste-to-energy plant is set to tackle both problems at the same time, by helping to dispose of three-quarters of the city’s rubbish while generating enough electricity to power a third of […]

Your gadget’s next power supply? Your body

Posted on Tuesday, February 13th, 2018 by

Searching for a power outlet may soon become a thing of the past. Instead, devices will receive electricity from a small metallic tab that, when attached to the body, is capable of generating electricity from bending a finger and other simple movements. That’s the idea behind a collaborative research project led by University […]
