I think it is clear enough: the question is about SOLID tide...not about oceans and seas

The tide moves a huge amount of water twice each day, and harnessing it could provide a great deal of energy - around 20% of Britain's needs for instance.

Although the energy supply is reliable and plentiful, converting it into useful electrical power is not easy.

Only around 20 sites in the world have been identified as possible tidal power stations.

To learn more I've suggested some resource materials in the sources section for you.

Sorry, a lot of answerers here aren't very quick. Maybe you can write more slowly for them :-) The asker is referring to the fact that the earth's solid bulk rises and falls due to tidal forces.

The problem with using this displacement to perform work is that you would need something for this displacement to push or pull against. Things *on* earth will just rise and fall with the surface. You would have to, for example, drill a hole to the center of the earth, throw down a rope, and anchor it to the core. The rope would then stretch and relax with the tide. This could be used to perform work on a generator. Not very practical.

Ocean tides avoid this problem because water is a fluid. It flows laterally to maintain an equipotential surface, allowing it to increase in height *relative to* the land because the land lags behind due to its greater inertia. This differential allows water to be dammed and discharged through a turbine when the tide goes out.

no but I have imagined it, and yes it is real, because of the quantum accumulation of static electricity produced when geo locations are flexed by the elastic bubble like shape of the earth within its atmosphere. The same should be true of any planet with an atmosphere that rotates on an axis.

there's ways of designing batteries that take the chemical action of H20 being forced to electrolosis itself through an exact frequency that Andrija Puharich figured out was probably around 4.6 hz or something...

batteries can essentially exactify this low low frequency from nuisance designs in what i guess is mostly just a way of containing energy through resonant field harmonics that orchestrate the chemical anomalies seen in atomic stabilities that ultimately reflect something like the limitations fo originality in fractal coherence and structuralizational tactics involving the limits of human perception given a specific medium such as directable currents existing in ac/dc and ac/dc even coming to form something called "xc" which is a chemical idiosyncratic method of absolving the instabilities as dependent upon a specific unlocking/relocking that is almost exclusively a solar battery gone on steroids.. sorry to say this but there's even infinite energy through proper use of magnetism and copper constructs and the 7.4hz harmonic which still remains to be "proven"..

really if u want the formulae for prime numbers of series x its done this way: take a 3-d ellipse of magnetic foci and a skin/ vibration of 7hz w/ a very steady flux of 6-8 as a foci diameter.. this results in a specific tendency to store vibrational energy that essential = x where x is the number of complete 6-8 vibrations where prime series x is the amount of temporal distortions of 7hz that equate to a merging of the 2 foci where they exist as a non conformist / non existential compilation sequencing

Yes, and there exist models of such devices as use the tides to generate electricity. The Dutch are light-years ahead of the rest of the world in this regard, I believe...

The amount the Earth's crust is lifted by the moon's gravity is too small to harness economically.

No. Their displacement is quite insufficient.

you haven't, you are about as bright as a 3 watt light bulb.
