World problem solved

Keep adding water ever couple of months.

Course, if we did this, it would end oil production and we would end up with a ******* of pissed off middle eastern countries who rather dislike the fact that their underground plant-goo is worth less then a metal condom.

Yes, because the only thing we make out of oil is fuel. Plastic, medications, etc, all come from magical fairies.

Do you have a permit to generate that amount of power? Is your property zoned for it? How much in taxes will the Gov charge you?

I'm not OP so don't ask me. What if the government did it? What if it was just the same as you already pay for taxes, seeing as there is an unlimited supply of water?

put it in a vacuum where the water cant escape

How do you hermetically seal around the portals?

have the entire machine in the vacuum and have the wires with the energy lead out. you can seal around those
