no great problem just needs a bit of thought

1.175 Kw/sec

The rotational energy will surely be 'I omega squared/2' where I is moment of inertia. You must get your basics right or your sums will not be reliable.

Do you not understand, McQueen, that Force is not Energy. It is Energy that takes you from A to B. I can use a car jack to lift a 10tonne vehicle by a few cm, which requires an enormous force (100,000N), the amount of actual Energy I put in would be a few hundred kJ.

You are missing out on the whole argument, we are talking about gases under pressure, like when a scuba tank is punctured and takes out a whole block of buildings!!! So, yes power is present and it can be harnessed usefully!!!
