Forget the garlic. Put away your crucifix. IBMers in Zurich are working on a way to protect you from a 21st Century’s demon called ‘Vampire Energy’— the power used while you leave your gadgets and appliances turned off and plugged in. By developing a transistor that regulates energy usage, this innovation aims to cut your devices’ power consumption by as much as 90%. This could save U.S. households billions in power costs. A scary good trick, and an even better treat! Happy Halloween, everyone.
