Power your house with 5 liters of water per day

Sounds fanciful, but this is MIT talking…

MIT will announce its patent next week of a cheap, efficient, manufacturable electrolyzer made from cobalt and potassium phosphate. This technology, powered by a 6 meter by 5 meter photovoltaic array on the roof, is capable of powering an entire house’s power needs plus a fuel cell good for 500 km of travel, with just 5 liters of water.

The process, loosely based on plant photosynthesis, uses solar energy to split water into hydrogen and oxygen gases. When needed, the gases can then be re-combined in a fuel cell, creating carbon-free electricity whether the sun is shining or not.

It’s not in production yet. Let’s hope will be, and soon.
