Response to Treant (Reply #38)

Sat Aug 2, 2014, 09:29 AM

60. It's a thruster that requires no reaction mass.

Up until this gadget was invented, thrusters had to obey Newton's 3rd Law - for every action, there's an equal and opposite reaction.

So you had to carry fuel, or more precisely, reaction mass. To move forwards, you have to throw something backwards. A rocket works by squirting fuel and oxidizer into a combustion chamber, lighting it on fire, letting it explode violently, and let the exhaust gasses of the explosion shoot out the back to push the rocket forward.

This gadget for all intents and purposes pulls subatomic particles out of nothing, and throws them out the back, instead of throwing reaction mass that was brought along. Pretty cool, assuming it works!
