Hygroelectricity could be the Next Big Power Source

Hygroelectricity, or humid electricity could be the next big power source. We’re already making great progress in pulling electricity from the motion of the air & from the photons that stream through it, but what about pulling electric charges right out of the air itself?

1161 Hygroelectricity could be the Next Big Power Source

Researchers have solved a mystery about how electricity forms in the atmosphere, and in doing so may have found a way to pull electricity right out of the air.

Research unveiled today at the National Meeting of the American Chemical Society has defined the mechanism by which water vapor in the air become charged, a discovery which could lead to devices capable of creating electricity from the atmosphere’s own charges.

For a long time, scientists though that water droplets adrift in the atmosphere remained electrically neutral even after attaching themselves to dust particles or other particulates in the atmosphere. But recent evidence has suggested otherwise, which led Dr. Fernando Galembeck and his colleagues to dig deeper. What they found, and then proved in the lab, is that in fact water in the atmosphere does pick up a slight charge.

Aluminum phosphate and silica are two particles found commonly in the atmosphere. By using small particles of them,  researchers showed that in the presence of water vapor silica particles become more negatively charged. Aluminum phosphate grows slightly more positively charged. This building of charges in humid air can accumulate and be transferred to other objects, explaining phenomena like the charge buildup where steam escapes from boilers that had baffled scientists for centuries.

Galembeck and company call the quality “hygroelectricity,” meaning “humid electricity.” The property could lead to generators that pull charge right out of humid air to power buildings, as well as to panels that prevent lightning from striking in certain areas.

    Wonderful blog! I truly love how it? s easy on my eyes as well as the data are well written. I am wondering how I can be notified whenever a new post has been made. I have subscribed to your rss feed which need to do the trick! Have a nice day!
