OCEAN WAVE ENERGY: WAVING GOOD BUY?
THE idea of extracting energy from an ocean wave and turning it into electricity is an alluring one. It has the potential to fill in the gaps that are left by wind and sun power plants when it is calm and dark.
We calculate that the cost of producing electricity from the HUG will be around $0 .003 kilowatt hour. That compares with 16 cents a kilowatt hour for offshore wind farms, six cents for the onshore variety and a grid-connected fossil-fuel power station at five cents or more.
HUG Wave Energy Systems are ultra-simple, only three moving parts: the helical turbine, the submersible pump and the electric generator (which is accessible and kept dry). The simple HUG design will operate for decades with no more maintenance than an occasional scrub to remove accumulated barnacles.
The HUG uses higher waves to fill a higher reservoir to a greater water level than the surrounding ocean. The lower Pump HUG has a helical turbine, which engages a submersible pump in order to send water up a HUG pipeline to a second Funnel HUG above the water line on its own barge where its second helical turbine engages an electric generator in a dry environment.
Now let’s explain the real reason for the HUG: HIGH POWER DENSITY Continue reading HUG Wave Energy Systems
