Wave energy, the emerging renewable resource behind wind and solar, is gaining traction as innovators advance the technology of wave-energy converter devices.
For a U.S. Dept. of Energy design-build competition that drew 92 submissions, the judges on Nov. 16 selected one such device, which started as a garage project, for the $1.5-million top prize. The judges awarded two other submissions $500,000 and $250,000, respectively.
