The energy and mineral-rich state of Western Australia has agreed to build the nation's first commercial wave energy farm. It will use a system called Ceto, developed by WA's Carnegie Company. The technology consists of anchoring submerged buoys to the seabed, driving pumps by the motion generated by waves. The pumps push water under pressure to drive hydroelectric turbines on shore. Carnegie claims a number of key advantages for the system, including the fact that submerged buoys are not affected by storms and are able to adjust to a wide range of wave heights and directions. Carnegie also says that, unlike wind, waves can be predicted days in advance, allowing operators to match supply to demand. Read more here
