The water-powered clock: the most eco-friendly timepiece ever?

It doesn't need batteries, solar panels or winding, it just needs water. The Water Powered Clock sounds like something out of mythology, but it's real and it's turning H2O into energy somewhere near you.

All you have to do to keep the clock ticking is change the water every six months. It uses "the latest electrochemical technology" to power the digital display with water and there are no emissions or waste. Shaped like cans, the clocks are available in four colours.

It's not an alarm - water obviously isn't that powerful yet, but it does look quite cute and displays the time on the digital panel at that front. Pair it up with Efergy's showtime water-use monitor as a green present for the eco-warrier in your life.

Even better, get GreenStamp's water-powered clock making kit and let your green friend experiment with what liquids make the clock run. A good one for kids.

New hydrogen-storage method discovered

Sunday, November 22, 2009

Scientists at the Carnegie Institution have found for the first time that high pressure can be used to make a unique hydrogen-storage material. The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) under pressure to form a previously unknown solid with unusual bonding chemistry. The experiments are the first time these elements have been combined to form a stable compound. The discovery debuts a new family of materials, which could boost new hydrogen technologies. The paper is published in the November 22, 2009, advanced online publication of Nature Chemistry. Read more...
