Saving Earth from an Expanding Sun
... an ionosphere). Now you no longer have the armature of a dynamo but that of a motor. You’re cranking against Earth’s magnetic field and the electrodynamic tether rises. Space elevators Clearly this is a relative of the now-famous space elevator...

Evolution of volatiles on the Moon
...), the fundamental process of reconnection provided a pathway for the early Earth’s evaporated atmosphere to travel along the magnetic field lines all the way to the Moon, where the volatiles could be stored in the lunar soil - protected...
