1. Huge heating grids would require electricity wouldn’t they?Think about it.

2. The steam has to be under pressure. A lot of pressure! It is that pressure that cranks the reactor. The steam must always be contained within a “closed loop” system. It can not interact with anything or it will escape. I do not believe the heat generated from a grid system would be very easy to capture, pressurize and contain.

3. As one said, what will power the heating grids?

4. Still uses fuel…sun would be better but costs are not feasible.

5. Coal is never clean therefore not green. Clean coal production has been shown to be incorrect greening.
   To answer your question… They [who ever “they” are] could, but the energy factor would be very high for both and very energy efficient. Why go there when there are so many other viable ways to go?

6. First of all, heating grids will require humongous amount of electricity. Second of all, you just need to start the fire for burning coal; for water you need a constant amount of energy. Plus it takes longer to make steam out of water than coal.

7. Actually they already do boil water that way. Ignore all the silly facetious answers above. Geothermal energy uses the heat from the earth’s core to boil water. It rises in the pipes inserted down perhaps 1-2 miles. the steam rises to the surface and drives turbines and produces electricity. This form of energy production is now becoming economically feasible and you will see a lot more of it in the near future.
