Ocean Energy---An infinitely abundant, eco-friendly source of power

Project Synopsis.

EXPERIMENTAL PROJECT FOR POWER GENERATION THROUGH OCEAN WAVES

The experiment was carried out at Manganpudi Beach, near Machilipatnam, in Krishna District, in the State of Andhra Pradesh, in India.The Equipment, was placed about100 meters from the shore, in low tide. The unit functioned efficiently, in both high and low tides.

The height of the Unit is about 26 feet. The length of the unit i.e. the ocean front occupied by the unit is 6 feet. The width of the unit is about 5 feet.

The weight of the float used, is 1000Kgs to 1500 Kgs. (the weight can be varied as required).

The lifting capacity of the float, is about 2000Kgs (or even more).

There are, about 4 to 8 waves and sometimes 12 to 16 waves, a minute. (i.e. every 15 seconds, there is 1or 2 or 3 or sometimes even, 4 waves).

Each wave, gives mechanical energy, to the turbine, through the float, which is as follows;

1. An upward force, equaling to 2000 Kgs (i.e.the lifting capacity of the float) X height through which the float is lifted by the wave (I prefer, to call it an upward stroke); and,

2. A downward force, equaling to 1000 Kgs (i.e.the weight of the float) X height through which the float falls with the wave (a downward stroke).

Even if, the weight of the float and its lifting capacity is made less, when hundreds or thousands of these units, are placed, singly or in rows of 2 or more units, side by side, without any gap in between the single units or between the rows of units, along the coast, at depths of about 5meters to 10 meters or more of the sea, (so that, the incident wave acting on the single or two or more floats of a row, does not lose any of its energy to the ocean floor, and all the energy contained in that incident wave is used in lifting the single or two or more floats of that row), then, the combined energy, of all the floats, of all the rows, would be enormous.

All the units are interconnected and their mechanical energy, over a stretch of 1KM or more, is brought to a point, to run a single electric generator of a capacity, proportional to the total energy obtained from all the individual units.

In the above Experimental Unit, a Generator of 2 KVA of 1500 RPM was used and several bulbs of 100 Watts were lighted. Video coverage of the Power Produced was taken.

--------------------------------

Regarding ocean wave energy, one estimate puts that with swells of 9 feet, there is the energy of 755MWs per Sq.Mile and with swells of 5 feet there is the energy of 242MWs per Sq.Mile.

It is possible to construct floating Power Units. These floating Power Units are similar to the about units except that they are made to float using the Archimedes principle of buoyancy.It is the relative motion of the float to the unit that drives the turbine.Here too,hundreds or thousands of these units could be interconnected to run single electric Generators of over 100MWs(and possibility upto210MWs or more).Presently,Transmission through cables is a big problem. However, l hope,that young Scientists and Engineers in Universities the World Over will solve this problem through laser beam technology, as many properties of a laser beam, seem to be similar to that of a conductor.

Pollution and Global Warming are very very serious problems.We all sat at the edge of our seats while seeing the movie Titanic, probably because we are all sensitive and humane at our heart.But in reality, we are all on a different kind of Titanic which is moving at full throttle to hit the dooms day.I believe we still have the time to change the course and that too at full throttle.
