Oceans are a tough place for any technology, but Australia's AquaGen has plans to generate power beneath the waves even in the middle of the Perfect Storm.
The company's SurgeDrive equipment can be set up in "wave farms," a matrix of bobbing power-generating buoys connected to a very stripped-down version of an oil-drilling platform. The lines tying the buoys to the platforms also transport the generated electricity.
The buoys generate power while sitting on the energy-rich ocean surface and riding the waves, using the waves' energy to turn a turbine. In stormy conditions the buoys are simply pulled below the surface, where the more muted wave action will allow them to continue generating power without being damaged.
Since the buoys disassemble into smaller generating units, repairs are easy. Simply remove the broken SurgeDrive from its wave farm matrix to fix on land, while the rest of the farms continues generating power.
