Correct, It is a potentialy very deadly solution even with the best technology and has real and hidden costs that just keeps on costing. The savings on your electricity must always be subsidized by the state to remain affordable and sustainable. You can never pay off this debt even years after you have paid for the original capital cost and it always poses a constant danger both locally and nationally. It has it's limited and careful role to play as part of the energy program. But it must never be considered an energy solution from feelings of desperation. This is no easy fix in every sense of the word.
