We saw the force in the greatest of rivers and took it for our own. We thought, here is a massive amount of free energy. Let us take it to light and heat our homes and to run out computers and power our mills and factories. By slowing the waters we heated the rivers and killed some fish. Is that bad?

I read in the portland business journal about geothermal plants. Now we're trying to take heat out of the earth. How could that be a problem? The earth's core is a swirling ball of super-hot fluids. One might think that surely we cannot have an impact by dropping our pipes and poles to heat water which turns the turbines. This is a new, massive amount of free energy. You might want to invest.
