MIT's Self-Assembling Solar Cells Recycle Themselves Repeatedly, Just…

Plants are extremely efficient converters of light into energy, setting the bar for researchers creating photovoltaic cells. A team of MIT scientists believe they've created a synthetic chloroplast that can be broken down and reassembled repeatedly, restoring sun-damaged solar cells. » 9/02/10 4:40pm 9/02/10 4:40pm

The Next Alternative Energy Source: Electricity Out of Thin Air

It's been coined "hygroelectricity", which means "humidity electricity", and scientists are already in the early stages of developing devices to harness it. What is "it" exactly? "It" is electrically charged water droplets hanging in the atmosphere. » 8/26/10 12:00am 8/26/10 12:00am

Cheap, Printed Solar-Powered LEDs Could Change 1.5 Billion Lives

Photovoltaic cells printed on sheets aren't news, nor are LEDs and ultrathin lithium batteries. What's news is a combination of the three which can help give light to 1.5 billion people who live in impoverished areas without access to electricity. » 11/03/09 8:40pm 11/03/09 8:40pm
