How does electricity get generated? Except for solar, it comes from something that moves. Hydroelectric dams drive turbines, as do wind, tides and waves. And fossil fuels heat up liquids that make turbines whirl.
So, scientists are always on the lookout to harness moving things to create electric energy. And so it was that they thought about the water going to homes and businesses. After all, it’s usually moving along at a speedy pace as it heads to faucets, showers, baths and businesses everywhere.
And now harvesting that energy is becoming a reality in the form of small generators installed at various places in municipal water systems.
