New
Scientist: Ships that harvest energy from the waves and
store it in batteries could one day generate electricity from
the world's oceans more cheaply than today's wave-power
devices, writes Helen Knight for
New Scientist. The ships would sail to a suitable
location, drop anchor, and start generating electricity from
wave energy. Once their batteries were fully charged, they
would return to shore and feed the electricity into a grid.
Unlike conventional wave-power devices, the ships would not
need undersea cables to link to the electricity grid, which
would cut a significant fraction of the overall cost.
