Energy Ink’s self-charging battery extracts energy from humid air

Shares in Strategic Elements jumped 40 per cent when news broke that its experimental battery had moved from the milliamp-hour range to the amp-hour range. The company is keeping its technology secret, but journalists have learned that the battery’s basis was developed by Dr Deway Chu of the University of New South Wales and CSIRO. According to the doctor’s recent publications, it involves extracting energy from humid air.

According to some calculations, half of all solar energy reaching the Earth is spent on evaporating the moisture that covers 71% of the planet’s surface. In other words, moisture in the air is a kind of energy carrier, which Deway Chu has learnt to extract. He created a generator of hydrons (hydrogen ions – ed. Techkult) by treating graphene oxide with hydrochloric acid. The details of the technology are hidden, but in simplified form it looks like this: if one layer of a special plate is left dry and the other is wet, hydrons are formed, which migrate from the wet part to the dry part, which generates an electric current.
