The system turns light of white-glowing molten silicon into electricity using specialized PV cells. The researchers claim that the concept could store electricity at around half the costs of pumped hydro. A single system comprising two ten meter tanks could power 100,000 households.A team of researchers at the Massachusetts Institute of Technology (MIT) has proposed a new energy storage concept, which they claim is far cheaper than current energy storage technologies. The MIT team points to the scalability of its so-called "sun in a box' concept, saying that a single large system could power ...Den vollständigen Artikel lesen ...
