Building smart homes that are networked to run as efficiently as possible is supposed to be one of the technological fixes to our current energy consumption problem. But what’s often lost in all the heady talk about innovating our way to a greener future is the fact that those wireless networking technologies also consume power, reducing the net benefit.
Wiring large building for fire safety systems, climate control mechanisms, and other public safety monitoring schemes consumes a lot of wire -- imagine how much feet of copper connects every room, corridor, stairwell and broom closet in a building like the Empire State.
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.
