This is exciting. This article on MIT website is about the new way to use solar power, or rather a way to use it more like the plants. During the day using the power of the sun and with some basic accessible materials splitting water into oxygen and hydrogen storing them and at night when sun is down reversing the process and combining it back into the water using a fuel cell.
This is quite wonderful news and an idea that could bring energy independence to any home. I am just affraid that somehow the big guys who would loose money on this would prevent the widespread use of the technology or find a way to make it prohibitively expensive.
