  2. Tidal heating - Wikipedia

    en.wikipedia.org/wiki/Tidal_heating

    Tidal heating (also known as tidal working or tidal flexing) occurs through the tidal friction processes: orbital and rotational energy is dissipated as heat in either (or both) the surface ocean or interior of a planet or satellite. When an object is in an elliptical orbit, the tidal forces acting on it are stronger near periapsis than near ...

  3. Line art - Wikipedia

    en.wikipedia.org/wiki/Line_art

    Line art emphasizes form and drawings, of several (few) constant widths (as in technical illustrations), or of freely varying widths (as in brush work or engraving). Line art may tend towards realism (as in much of Gustave Doré 's work), or it may be a caricature , cartoon , ideograph , or glyph .

  4. Tidal heating of Io - Wikipedia

    en.wikipedia.org/wiki/Tidal_heating_of_Io

    Tidal heating of Io (also known as tidal working) occurs through the tidal friction processes between Jupiter and its moon. Orbital and rotational energy are dissipated as heat in the crust of the moon. Io has a similar mass and size as the Moon, but Io is the most geologically active body in the Solar System. This is caused by the heating ...

  5. Tidal stream generator - Wikipedia

    en.wikipedia.org/wiki/Tidal_stream_generator

    Two types of Tidal Stream Generators Evopod - A semi-submerged floating approach tested in Strangford Lough with SeaGen in the background.. A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from the ...

  6. Tidal acceleration - Wikipedia

    en.wikipedia.org/wiki/Tidal_acceleration

    Tidal acceleration is an effect of the tidal forces between an orbiting natural satellite (e.g. the Moon) and the primary planet that it orbits (e.g. Earth). The acceleration causes a gradual recession of a satellite in a prograde orbit (satellite moving to a higher orbit, away from the primary body, with a lower orbital velocity and hence a ...

  9. Tidal power - Wikipedia

    en.wikipedia.org/wiki/Tidal_power

    Tidal stream generators make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use the wind to power turbines. Some tidal generators can be built into the structures of existing bridges or are entirely submersed, thus avoiding concerns over aesthetics or visual impact.
