Lunar Power for all

Fancy trying a little Lunar Power to crisp your breakfast toast tomorrow?

Thanks to the gravitational pull of the Moon and the Sun,
the Earth’s ocean flows to produce high and low tides.

Put enough turbines in that flow, Worldwide, and you can generate
enough electricity to make everyone toasty.

As non-renewable fuels run out, tomorrow’s energy
has to come from Solar power on sunny days and Lunar
power 24 Hrs in every day of every year.

The Story of Lunar Power and one man’s life work to tap the energy of the tides for the benefit of all. (Based on a true story)

Is Lunar Power a hydro-electric power?

Yes, but hydro-electric turbines placed in rivers
use collected rainfall, so these depend upon the Sun’s
heat to evaporate water to create rain clouds.

However, turbines under sea water, placed in a good tidal flow, only
rely on the Moon staying exactly where it is.

Is Tidal Power new?
Not really. Before the year 1615, Sir John Carew used tidal power to mill corn and
from 1998, visitors to Carew Castle, Pembrokeshire, Wales, have been
able to see the 11 hectares (27 acres) tidal mill pond by the castle and watch the
mill’s reconstructed machinery grind corn.



A kind message on power from water that I received from the one and only Lucas Wyrsch

Dear Grant of the HoBB,

Thank you so much for your great comment and for sharing!

I like the L.M.L.F. (Large Mass Low Flow Turbines) concept that works with the Coriolis force!

Newton’s laws of motion govern the motion of an object in a non-accelerating inertial frame of reference.

When Newton’s laws are transformed to a uniformly rotating frame of reference, the Coriolis and centrifugal forces appear.

Both forces are proportional to the mass of the object.

The Coriolis force is proportional to the rotation rate and the centrifugal force is proportional to its square.

The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object’s speed in the rotating frame.

The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame.

Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work, for example, electricity generation, water desalination, or the pumping of water into reservoirs.

Machinery able to exploit wave power is generally known as a wave energy converter or WEC.

Wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents.

Wave power generation is not currently a widely employed commercial technology although there have been attempts at using it since at least 1890.

In 2008, the first experimental wave farm was opened in Portugal, at the Agu├žadoura Wave Park.

Tidal power, also called tidal energy, is a form of hydro-power that converts the energy of tides into useful forms of power – mainly electricity.

Although not yet widely used, tidal power has potential for future electricity generation.

Tides are more predictable than wind energy and solar power.

Among sources of renewable energy, tidal power has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability.

However, many recent technological developments and improvements, both in design, e.g. dynamic tidal power, tidal lagoons, and turbine technology, e.g. new axial turbines, cross flow turbines, indicate that the total availability of tidal power may be much higher than previously assumed, and that economic and environmental costs may be brought down to competitive levels.

Historically, tide mills have been used, both in Europe and on the Atlantic coast of North America.

The incoming water was contained in large storage ponds, and as the tide went out, it turned waterwheels that used the mechanical power it produced to mill grain.

The earliest occurrences date from the Middle Ages, or even from Roman times.

It was only in the 19th century that the process of using falling water and spinning turbines to create electricity was introduced in the U.S. and Europe.

The world’s first large-scale tidal power plant, the Rance Tidal Power Station, became operational in 1966.

Have a great and happy day!
