Water And Sea surge Primed Hydro-Electric Atoll Dams - WASPHEAD

Considerable concern must arise from the obvious limitations on all wind turbines and wave harvesting mechanisms.Particularly their susceptability to the vagaries of the weather however efficient the technology of turbine design, 100% is as nothing if there is no wind at all.
   As the percentage of the grid supplied by turbines increases, the more pressure there is to build conventional back-up power stations and the notion of reducing the CO2 footprint will get lost when they come into play; the hitherto unannounced costs for such back-up is a further issue. Conventional battery technology is still too costly and underdevoped to be considered as a storage mechanism.
   Hydro-electricity (ie waterhead storage) has been around for over a century and now accounts for about 35% of global electricity production.
   It still offers the crux of a solution to rationalizing renewable energies. Of course it requires an ocean of water and that is precisely where the waterhead will be placed.

A Safe Dam Complex to Extract Store and Convert

A conceptually single but integrated multi-faceted structure, effectively resulting in a massive multi-purpose dam, which is constructed from, and which is compartmentalized internally by, compacted inter-connected and isolatable silos for the purposes of construction, safety and economy. It is preferentially sited on the sea bed and raised high above sea level to capture wind, wave, tide and solar energies, and convert and store that energy as a waterhead. It provides the facility to convert that water head into hydro-electricity in a controlled manner to best sub-serve the needs of a national grid.
The fabric of the silos accommodates the machineries for this. The storage facility can accommodate pumped water from any other machineries outside its boundaries, ie wind turbines in hundreds if not thousands, in the sea surrounding the island contributing directly to the water head, instead of producing electricity.
Provision for covering the silos allows this to be specially contoured so as to enhance flow of wind over the pure wind turbines sited on and over it. Dedicated silos at its periphery provide housing for a particular mechanism in which flotation drums, fitted with marginal turbine cusps, can both rotate and slide up and down on fixed vertical spindles, to capture the energy of tide and wave. The abutting or overlapping lids of the silos offer an immense sky-facing surface for solar power and the collection of rainwater in silos located at the periphery of the complex.
The silos, by virtue of their large numbers and size, their abutment and confluent cover, have the appearance of, and are effectively, islands which may be square kilometers in area and of some three hundred meters in height. Such heights presents to the turbines thereon the better wind conditions or increased wind shear than occur at sea level.
