To the sea we go?

A moment moving downstream…

There's a cycle, of course. It evaporates. Falls from the sky. Then makes its way to the sea to do it all over again. It's good sometimes to stop and stare at just a moment in the journey. Energy in action. // That's one reason harnessing river currents has made hydro power such an important source of energy for centuries. New England rivers are riddled with dams – some working, others in ruins – that powered mills and the early days of electricity. And out west, the Hoover, Grand Coulee and other dams tower in proportion. But damming river currents can cause problems – from cutting off fish migration routes to altering the wider ecosystem. Not a lot of talk about expanding river dams anytime soon. // But what about harnessing the water's power as it stalls in the cycle, lingering in the ocean? There, at land's edge, the ebb and flow moves currents that are clean. Energy untapped. Not a lot of talk about tidal power, either. But it seems something worth considering in a world that needs to cut its use of oil, gas, and coal, and fast. There are a few big efforts at damming bays, but those too come with big impacts. The question is how to tap the tides more deftly. That means caring again about the natural cycle. And stopping to study that rise and fall that happens twice a day, as reliable as the moon in the sky above. #water #power #travel #journalism #energy #maybe #tides
