>>	Anonymous Mon Oct 4 14:57:09 2010 No.1848137 You can jump in midair? Even if you could, you need to jump up faster or equal to the speed you're falling to neutralize your momentum. Otherwise you'll just reduce your falling speed slightly before splattering onto the concrete.

>>1848129
Then it's possible to survive if he were able to jump with an absurd amount of force--enough to shoot the table beneath him and stop his velocity relative to the ground.

He'd have to already be able to jump with the force to bring him up to the top of the building.

Magnetic lines of flux travel through the air from one magnetic pole to the other. Magnetic shielding doesn't actually block them; it just changes where they pass through. The device doesn't work (it's been tries countless times before).

>>	a Mon Oct 4 15:38:09 2010 No.1848295 >>1848278 The gained energy will be less or equal than the inputed energy. Inputed energy includes the magnetic energy. At best you will transform magnetic energy to electric energy.

>>1848281
There's no such thing as magnetic "energy." You don't wear them down like batteries or something. The only reason they lose magnetism is because heat energy eventually causes the atoms' spins to become scrambled.

There's as much "magnetic energy" as there is "spring energy." You'd have as much luck building a perpetual motion device from springs.
