You know, "Real Genius" is both good and kind of terrible as a movie. Archive: https://archive.today/UxOr4 From the post: >>Wireless power transmission is moving from lab curiosity toward real-world utility, at least if the Defense Advanced Research Projects Agency's latest test is any indication. DARPA says the Persistent Optical Wireless Energy Relay (POWER) team program managed to transmit more than 800 watts of power from a laser emitter to a receiver located 5.3 miles (8.6 kilometers) away during a 30-second transmission. To celebrate the achievement, POWER used some of the transferred energy to make popcorn - an homage to Real Genius, the 1985 Val Kilmer film where slacker grad students thwart a plot to weaponize high-energy lasers. For reference, 800 watts isn't a ton of electricity, but it's enough to run a small fridge, lights, or an RV setup. It's a practical start, assuming the tech scales as DARPA intends. And it's not just about popcorn and personal gadgets - DARPA has its eyes on the battlefield.
