Fly Wheel Powered Liquid-Cooled Radiator

Salutations, Im working on building a liquid cooling radiator system, and I dont want to use electricity. I want to install it on a fly wheel, and use the mechanical energy from the flywheel to power the water pump. I was thinking of using a tesla turbine, and gearing or using a magnetic coupler to transfer the rotation from the flywheel directly to the pump(Tesla Turbine) so as to not waste heat or energy by converting into electricity for an electric pump.

Also I need this cooling unit to cool down a specific section, by ten degrees F in a half of a second. then after the liquid absorbs the heat from this section it should run through heat exchanger fins to disperse that heat, then back through the pump and re-cycle every half second.

I think a tesla turbine would work best, but if you have better pump suggestions it would be kindly appreciated, also Im in need of the best way to flush the water over the heated section so to cool it as quickly and efficiently as possible.

would I require a compressor or would fins work well enough for only a ten degree temperature difference?

I know i will need a thermostat and a flow meter, any other instrumentation i may need?

Thanking you for your cooperation I am,
