What we’re seeing is Lichtenberg Figures form from an electron beam getting zapped into an acrylic prism. The electric trail of the lightning strike is so badass. It’s like trapping a lightning bolt in a glass box forever, a force of nature on display. »

Researchers at Rensselaer Polytechnic Institute and MIT have developed a battery that uses carbon nanotubes and paper to make a flexible battery that can be cut by scissor and could eventually be printed. The energy density is fair, at about 110mAh/gram, and small prototypes are powerful enough to power small fans.… »
