Temperature is how fast things hit each other.
Density is how often things hit each other.
Time is how many times things hit each other.

So... temperature is velocity of things. Why waste your time heating a
bunch of stuff up to some sort of temperature when you can just
accelerate one bunch of stuff one way and another bunch of stuff the
other and have them hit each other in the middle?

At least you know you've given them enough temperature in the first
place.

The crux of the open test tube is...... having given them that
energy..... can you recover it in an efficient manner. If nothing
happens can you get back what you've put in. Better still, if something
does happen have you got a way of getting that energy out.

Your average sledge hammer is a closed system with all things blatting
off right left and center. Pitiful, poisening one hit rubbish.

If you can recover the energy you put in then density and time are no
longer such an issue. You just recycle the bits and the energy. Fire two
beams at each other. Do it in solenoids, recover the energy and recycle.

Simple Ay?
