Dr. Frits Bliek and his team at Ocean Grazer  are building an "Ocean Battery" that brings hydrodam technology to the sea.

On this episode of Here's an Idea™, Bliek, CEO of the Netherlands-based energy company, talks about an innovative idea for power that involves plastic bags, underground reservoirs, and a big drill.

How Does the Ocean Battery Work?

The battery pumps water from underground reservoirs into flexible bladders, just above the seabed. When there is a demand for power, the water, pressurized by the sea, is routed through hydroturbines in the tube to generate electricity.
