Sounds like a great power generator and heater for use in Antarctica.

The reason you do not want to shut it down, is because it needs energy to start the reaction and another boost of energy to kick it into self-sustaining mode.

In there business model, they did mention that one of the byproducts is heat. There are definitely some more challenges for them ahead, but that is what the field tests are for.

Steem on,
