Magnetic catapult to space?

Magnetic Catapult a feasible advanced earth launcher.
February 11, 2008
"A 9000 meter long magnetic catapult was proposed in 2003 by Warren D
Smith, mathematician at Temple University. It was designed to launch 5
meter long, 1 meter diameter projectiles at 2250 gees of constant
acceleration with a launch velocity of 20km/s (twice earth escape
velocity, Mach 58). It would cost about $2-20 billion to build and
operating costs would be $10-100 million/year. This system is not a
railgun and is not a coilgun."
