"Near limitless energy". ..

OK what are the limits? Preferably absurd answers please..

Since everyone else gave a joke answer I'll take a stab in the dark and say the upper limits would be the availability of hydrogen and physical limitations in transforming heat output into electricity. The hydrogen is the most common element but 96% of it is currently produced from fossil fuels. After that, it would be how well you can scale up turbines to efficiently convert heat to electricity.

If you have fusion energy, creating H2 from water via electrolysis is a joke. You can do it at home. It only requires a lot of energy. But with energy from fusion it will become super easy, barely an inconvenient

Well. Assuming the cost of splitting water is lower than the energy produced from the same amount of hydrogen.

It is muuuuuuuuuuch lower. The actual energy is incomparable, like an ant vs superman level of energy.

The energy in practice it'll be extracted from H2 has to be much higher for the process to have a practical use
