Episode 132: Space Elevator

Imagine a giant vertical railway stretching 100,000 km from the equator, somewhere in the Pacific, straight up into space. Instead of expensive, polluting rockets, the space elevator offers a smooth, slow electric ascent to Earth orbit. This "bridge to the stars" connects a floating Earth platform at 36,000 km to a massive counterweight located 64,000 km farther out. It is held taut by the Earth's rotation.
