    MIT’s Thermal Resonator Generates Electricity From The Air’s Daily Temperature Cycle

    The active component of the thermal resonator is a foam made up of copper or nickel that is infused with a phase-changing wax known as octadecane, which liquifies and solidifies at certain temperatures. The foamy mix is coated in a layer of graphene, which is an excellent thermal conductor.

    Batteries are currently taking over ground transport with electric cars and trucks, but battery technology is improving so quickly that it is soon expected to spread to air transport soon.

    Here’s How Graphene Makes Photodetectors 100,000 Times More Responsive Than Silicon

    Here’s How Graphene Makes Photodetectors 100,000 Times More Responsive Than Silicon

    “In a way, this mechanism is not too dissimilar to electron-hole recombination in semiconductor photodetectors,” exaplained Lozada-Hidalgo.  While the mechanism may not be too different than semiconductor photodetectors, these devices are based on proton transport as opposed with all current photodetectors today, which are based on electron transport. 

    New Rechargeable Batteries That Use Iron Instead Of Cobalt Could Be A Game Changer For Electric Cars

    New Rechargeable Batteries That Use Iron Instead Of Cobalt Could Be A Game Changer For Electric Cars

    It would be a dull month if a new rechargeable battery project didn’t make headlines amid all the excitement surrounding electric cars. This month’s indisputable winner is the lithium-ion battery that replaces cobalt with iron, and-rather surprisingly-works, at least according to the people who came up with the idea.
