  2. Solar mirror - Wikipedia

    en.wikipedia.org/wiki/Solar_mirror

    A solar mirror contains a substrate with a reflective layer for reflecting the solar energy, and in most cases an interference layer. This may be a planar mirror or parabolic arrays of solar mirrors used to achieve a substantially concentrated reflection factor for solar energy systems.

  3. Space mirror (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Space_mirror_(climate...

    Space mirrors are designed either to increase or decrease the amount of energy that reaches a planet from the sun with the goal of changing the impact of UV radiation; or, to reflect light onto or deflect light off of a planet in order to change the sun's lighting conditions.

  4. Heliostat - Wikipedia

    en.wikipedia.org/wiki/Heliostat

    The mirror is aligned to reflect sunlight along the same polar axis in the direction of one of the celestial poles. There is a perpendicular secondary axis allowing occasional manual adjustment of the mirror (daily or less often as necessary) to compensate for the shift in the Sun's declination with the seasons.

  5. Concentrated solar power - Wikipedia

    en.wikipedia.org/wiki/Concentrated_solar_power

    Lightweight curved solar-reflecting mirrors are suspended from the ceiling of the glasshouse by wires. A single-axis tracking system positions the mirrors to retrieve the optimal amount of sunlight. The mirrors concentrate the sunlight and focus it on a network of stationary steel pipes, also suspended from the glasshouse structure. [49]

  6. Znamya (satellite) - Wikipedia

    en.wikipedia.org/wiki/Znamya_(satellite)

    The Znamya project (Russian: Š—Š½Š°Š¼Ń, meaning "Banner", Russian: ā“˜) was a series of orbital space mirror experiments in the 1990s that intended to beam solar power to Earth by reflecting sunlight. The project was the brain child of Vladimir Syromyatnikov, who served as the project's lead engineer. [1]

  7. Heliograph - Wikipedia

    en.wikipedia.org/wiki/Heliograph

    A heliograph (from Ancient Greek į¼„λιος (hįø—lios) 'sun' and γρĪ¬φειν (gráphein) 'to write') is a solar telegraph [1] system that signals by flashes of sunlight (generally using Morse code from the 1840s) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter. [2]
