Ocean boosters like to compare the kinetic energy stored in the sea to a ginormous oil reserve that’s never going to run dry. It doesn’t matter if the sun shines or the wind blows. The tides turn. You can set your watch to them. The trick is how to generate cost-effective, renewable electricity from that limitless, ceaseless motion.

Oscillating hydrofoils. Tidal kites? Seriously. And it gets more out there.
