The good part: "Researchers at MIT claim to have found a novel new way to store energy using nothing but cement, a bit of water, and powdered carbon black – a crystalline form of the element.
The materials can be cleverly combined to create supercapacitors, which could in turn be used to build power-storing foundations of houses, roadways that could wirelessly charge vehicles, and serve as the foundation of wind turbines and other renewable energy systems – all while holding a surprising amount of energy, the team claims. "
The bad part: "According to a paper published in the Proceedings of the National Academy of Sciences, 45 cubic meters of the carbon-black-doped cement could have enough capacity to store 10 kilowatt-hours of energy – roughly the amount an average household uses in a day. A block of cement that size would measure about 3.5 meters per side and, depending on the size of the house, the block could theoretically store all the energy an off-grid home using renewables would need."
I don't know nearly enough about electricity and batteries...pershap @Doctor-Phibes can opine?

The saying, "Lite is just one damn thing after another," is a gross understatement. The damn things overlap.

I don't really know enough about them, either. Batteries do tend to have a much shorter life-span than houses, so I think that would be a major concern. Supercapacitors are being used quite a bit more now in electronics - often to provide a short-term high output.
This does sound like something we could conceivably get involved with at work - my company has a lot of links with MIT, and also does a lot of work with using renewables safely with buildings.
