Using Sun's Energy to Split Water Means Solar Power All Night
phorm writes "Reuters is carrying an article about a recent MIT development which may pave the way for solar-energy to be collected for use in low-input periods. According to Reuters, the discovery of the a new catalyst for separating hydrogen+oxygen from water requires only 10% of the electricity of current methods. This would allow storage-cells to function as a form of battery for other forms of energy-collection, such as solar panels. The new method is also much safer (and likely environmentally friendly) than current methods, which require the use of a dangerously caustic environment, and specialized storage containers." sanjosanjo points out coverage of the process at EE Times, which features the MIT group's press release.
Lets say your house needs 5000 W.
Let's not. That's more power draw than the total available service into most houses; and most houses don't exactly draw at max for 8 hours straight. Divide your numbers by 5, and you have a more reasonable estimate.
