What: A 10,000-year storage facility for radioactive nuclear waste
Where: yucca mountain, nevada
Cost: $58 billion
Crux: Approximately 60 miles of access and emplacement tunnels to house stainless-steel waste casks. A robotic transport system of gantries, cranes and railcars.
A reader inquires: Why don't we just take all the nuclear waste, throw it into a rocket, then launch the rocket into the Sun? Would this make the Sun explode?
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.
