H2O2 is a terrible coolant. let me explain why:

1. its unstable. Airtight or not, the H2O2 will break down into H2O due to it being moved constantly. When it does it will release that extra Oxygen molecule and you will start to accumulate O2 in the system.

2. its reactive... you dont want any metal in the system... bottom line. Aluminum, copper, and especially silver.

3. breaks down in light, so if you have clear lines it will break down into H2O with just background UV light hitting the lines.

I played with H2O2 a while back, was cool, but really was unimpressive due to the almost soda like carbonation the water seemed to develop with the release of Oxygen from it as it broke down.

The reason they use it in torpedo's is because its fuel.... it reacts so violently in high concentrations (40%+)(stuff you can buy without a license is under 1%, most likely .3%) that it is a excelent fuel for propelling stuff like torpedo's. Even some ICBM scale rockets use a H2O2 and Silver reaction to launch them into space. real H2O2 is so bad you dont want to be any where around it in high concentrations, it will disolve organic matter rather fast, and react with most metals.
