Hydrogen from the air?

post-image

Scientists in Australia have produced extremely pure (99+%) hydrogen using moisture captured from the air and electrolysis powered by the sun. The technology is known as Direct Air Electrolysis (DAE) and poses a very real promise for water-scare regions.

Even more impressive when you think that it can operate in locations with relative humidity levels as low as 4%. As a point of comparison, the average daytime relative humidity at Uluru (Ayers Rock) in the central desert of Australia is (apparently!) 21%.
