Brazilian scientists see new source of renewable energy in atmospheric humidity

by Jasmina Nikoloska

Believing that electricity could be generated from the air, Brazilian scientists are working to discover the processes involved in the formation and release of electricity from water in the atmosphere.

Contrary to the previous belief that water droplets in the atmosphere were electrically neutral and remained so even after coming into contact with the electrical charges on dust particles and droplets of other liquids, the latest evidence has shown that water in the atmosphere really does pick up an electrical charge, Wired UK reported on 27 August 2010.

The research was presented at a meeting of the American Chemical Society in Boston by study leader Fernando Galembeck, PhD, from the University of Campinas (Brazil), who confirmed that laboratory experiments had proven “hygroelectricity”, or humidity, which meant that “water in the atmosphere can accumulate electrical charges and transfer them to other materials it comes into contact with”.

It might sound hard to believe, but a team of scientists from the university is working to develop suitable devices to capture electricity from the air, and then eventually to use it to power houses and businesses.

Although the research is still in its early stages, Galembeck presented…
