Most of you may or not know what pressure, infact, raises the flammability of ceirtan materials.

Lets take insl for example, slow burning, non-conductive, non-explosive.

Now lets put it in a vacuum chamber. Try to burn it, won't work.

What if we put it in a pressure chamber? Buurn baby buuurn!

So how can this be used?

You could technically use Insl as very variable fuel. Your engine's low on fuel? Outer space pressure. Need a boost? Atomic bomb pressure.

Now, high flammability usually starts to burn into plsm. So higher pressure should turn Burning wood into Deadly burning liquid oxygen right? Nope! Surprisingly it retains the same heat, but just burns faster.
