How is hydrogen peroxide used to propel a torpedo?
Explain the mechanics of how hydrogen peroxide propelled a torpedo.
answers (1)
Most of the vehicle engines get the oxygen for combusion from the air around it. Hydrogen Peroxide (H2O2) is used in torpedos because it does not need an oxidizer.
Here is a good reference I found online.

A combination of hydrogen peroxide and silver serves as an ideal fuel. The hydrogen peroxide needs to be extremely concentrated to perform the task.
It contains about 90 per cent oxygen, in contrast to the hydrogen peroxide commonly available, which typically has a concentration of 3 per cent only. When silver and hydrogen peroxide interact chemically, the silver acts as a catalyst.
This reaction frees the extra oxygen atom to produce water, generating a lot of heat in the process. The heat turns water into steam, which the engine can eject at a very high speed through a rocket nozzle.
This ejection of high-speed steam powers the torpedo towards its target.

If the silver and H2O2 catalyst work in water then will it also work in air, as a form of propulsion? Could you fly a plane on steam power?
