Ten 200-ton buoys - each measuring 45m by 12m - are being installed off the coast of Oregon to build America's first wave power farm. They'll power 400 homes by harnessing "the energy of wave motion". Worth $US60 million?
Of course, of course. Clean, renewable energy is almost always worth it. The trouble with wave farms is that they haven't shown much success yet. They're currently about six times as costly as wind farms, are easily damaged by large waves, and the first ones didn't work out so well:
The world's first commercial wind farm opened in 2008 in Portugal, but power production was suspended due to financial difficulties. Moreover, two years ago, a Canadian-produced wave power device sank off Oregon's coast.
