How to Harvest Vast Tidal Energies: Innovative Tidal Sails Device Further Optimized
In the long sprint to find new sources of clean, low-cost power, slow and steady might win the race -- the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of wate...
