    Electricity from waste heat thanks to a pyroelectric nanogenerator

    How Nanogenerators works



    Taking advantage of the triboelectric effect, Professor Zhong Lin Wang and his team at Georgia Tech are harvesting wasted power with nanogenerators that capture mechanical #energy from sources ranging from walking to ocean waves. The #technology is also used in a new type of self-powered sensor capable of detecting very minute vibrations. [VIDEO] #physics

    The Tycho supernova remnant is the result of a Type Ia supernova explosion. The explosion was observed by Danish astronomer Tycho Brahe in 1572. More than 400 years later, the ejecta from that explosion has expanded to fill a bubble 55 light-years across. In this image, low-energy X-rays (red) show expanding debris from the supernova explosion and high energy X-rays (blue) show the blast wave - a shell of extremely energetic electrons.
