Ocean research, navigation, seafloor mapping, object-tracking (sonar, for example)—they all rely on sound, which is still the best way to transmit information through water. So we wanted to build the ultimate hydrophone, one that could listen to the quietest sounds and the loudest sounds and could work anywhere, even six miles underwater, where the atmospheric pressure is 1,000 times as much as it is up top. Whale ears were our inspiration.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
