In fact, it's impossible to reach orbit this way, as any orbit would
have to contain the point it left the device from and it would have to
have the same velocity vector there (in a inertial coordinate system in
which the Earth rotates). So, any such orbit would have to cross the
Earth's surface. A rocket motor has to be used after launch to change
the orbit. A hyperbolic escape trajectory is, of course, possible
without using a rocket engine.

Going up "tens of thousands of feet" is only a tiny part of energy
