TIDAL POWER ~ new technologies

twin turbines with tanks web

This concept drawing shows a 5-vane involute-spiral-vaned water turbine mounted on 4 pilings in a tidal current. Above the water turbine and a platform is mounted an involute-spiral-vaned wind turbine.  This concept is explained in detail in another area of this website.  These are both drag-propulsion devices, which have the potential of harnessing much more power than lift devices from slow-moving fluids, especially water.  The involute spiral has the unique property of creating a non-constricting path through the turbine, which is essential for harnessing maximum power from water, which is non-compressible and 800 times as concentrated as wind power.

Both turbines are connected to generators which provide power for electrolysis of water to produce hydrogen and oxygen for storage in the two cylindrical tanks below. This allows remote on-site storage of variably-generated electricity converted to hydrogen, which can be directly transferred to ships to power their own engines and to transport elsewhere.

Many variations on this design are proposed for different situations.  It is especially promising for harnessing tidal power here in Puget Sound, Washington, where vast tidal flows surge in and out of this large inland sea daily. I will be happy to discuss this more with interested parties.

H2O_Ship1 in water-spud anchors

Here is another tidal power-to-Hydrogen device proposed by Dr. Elijah Bonesteel.

A hollow ferrocement hull is anchored in a river or tidal current, where the paddle blades are turned by the water to generate electricity, which is used to electrolyze Hydrogen and Oxygen from water, storing it in compartments in the hull. Note the person on deck for scale.
