Tidal power is now a legit source of renewable energy

Tidal power, produced from the force of our planet's oceans sloshing to and fro, has always seemed like a neat idea. But the challenges of making it work -- imagine giant underwater propellers having to withstand strong currents and the unending assault of the sea -- made it seem less than realistic. But now manufacturing giant Siemens is throwing its weight behind tidal power startup Marine Current Turbines , which has had a 1.2 megawatt demonstration turbine operating beneath the waves of Northern Ireland's Strangford Lough since 2008. Siemens' interest is simple: Tidal power is super predictable. (Predictable as the tides, even.) As Peter Fairley reports at Technology Review : Solar and wind farm operators struggle to predict tomorrow's output, and bad forecasts can wreak havoc with power transmission planning and market prices. In contrast, the gravitational pull of th...
