Molten Salt Heat Energy Storage and Efficiency of Conversion of Heat to Electricity

MIT researchers have a new energy storage design that will store heat generated by excess electricity from solar or wind power in large tanks of white-hot molten silicon. It converts the light from the glowing metal back into electricity to get energy back out. It should be vastly more affordable than lithium-ion batteries. It should …

Wireless power that is 97 percent efficient could revolutionize highway transportation

Stanford researchers have designed a new technology that could lead to wireless charging of electric vehicles while they cruise down the highway. This wireless transfer scheme has an efficiency of 97 percent. The transfer range is one fifteenth of the wavelength. The range is 2 meters for a 10 megahertz system. The transfer efficiency can …

Robin Hanson discusses futurism

Here are three observations on futurists by Robin Hanson 1) Most folks I know who self-describe as future-oriented seem obsessed with the latest tech press releases. hey constantly circulate links on new tech gadget demos and analyses. Which might make sense if “the future” meant the next ten years. But if “the future” means the …
