The first thorium salt reactors in over 40 years were just switched on in Europe – ScienceAlert

http://www.sciencealert.com/researchers-have-conducted-the-first-thorium-salt-experiments-in-over-40-years#.WaUkb5ppSUB.facebook Netherlands-based nuclear power provider, NRG, are taking a gamble. They’re conducting experiments that could see a shift from uranium-based nuclear power to thorium. There has been the historical battle between using uranium or thorium as a nuclear fuel. Uranium provided a potential source of weapons-grade plutonium. A significant advantage of using thorium over uranium is it doesn’t

People Are Using Old Laptop Batteries to Build Their Own Versions of Tesla’s Powerwall

https://futurism.com/people-are-using-old-laptop-batteries-to-build-their-own-versions-of-teslas-powerwall/ Tesla’s Powerwall was intended to provide a convenient way for homeowners to store electricity for future use, such as when the power goes out. But with a $5,500 price tag, they haven’t been affordable for many consumers.  Some who had been interested in the tech, however, decided to try to make their own: constructed their own powerwalls by utilizing
