This morning in Switzerland, the Large Hadron Collider successfully ramped its twin proton beams up to 3.5 TeV for the first time. This is the highest energy a particle accelerator has ever achieved. The next step: collide the two beams, at a combined energy of 7 TeV.
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.
