Tidal power is now a legit source of renewable energy | Grist
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.)
