Liftport space elevator
Plans for a space elevator as a cheaper, safer alternative to riding on explosives have encountered a hitch. New Scientist reports that:

humans might not survive thanks to the whopping dose of ionising radiation they would receive travelling through the core of the Van Allen radiation belts around Earth. These are two concentric rings of charged particles trapped by Earth’s magnetic fields.[Source]

Liftport plan to get around the problem by increasing the shielding on the lifts. Shield mass will entail 100-tonne lifters for a passenger complement of 20.

Wikipedia have an entry of the physics and history of the concept of space elevators.
