So far, at least hydro-electric power, coal power, wind power, solar power, and wood power are well known. Until a few days ago, I had never heard of stone power. Then I learn about a quarry in a mountain in Bremanger i Norway, where the Bremanger Quarry company is extracting stone and dumping the stone into a shaft leading to its shipping harbour. This downward movement in this shaft is used to produce electricity. In short, it is using falling rocks instead of falling water to produce electricity, and according to its own statements it is producing more power than it is using, and selling the surplus electricity to the Norwegian power grid. I find the concept truly amazing. Is this the worlds only stone power plant?
