The effect on whales has been well documented—its akin to you or I standing next to a jet engine without ear protection.
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.
