  2. Solar pond - Wikipedia

    en.wikipedia.org/wiki/Solar_pond

    Solar Evaporation Ponds in the Atacama Desert. The largest operating solar pond for electricity generation was the Beit HaArava pond built in Israel and operated up until 1988. It had an area of 210,000 m² and gave an electrical output of 5 MW. [3] India was the first Asian country to have established a solar pond in Bhuj, in Gujarat.

  3. Floating solar - Wikipedia

    en.wikipedia.org/wiki/Floating_solar

    Floating photovoltaic on an irrigation pond. Floating solar or floating photovoltaics (FPV), sometimes called floatovoltaics, are solar panels mounted on a structure that floats. The structures that hold the solar panels usually consist of plastic buoys and cables. They are then placed on a body of water.

  4. Water aeration - Wikipedia

    en.wikipedia.org/wiki/Water_aeration

    Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms. [1]

  5. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    Solar roof ponds for solar heating and cooling were developed by Harold Hay in the 1960s. A basic system consists of a roof-mounted water bladder with a movable insulating cover. This system can control heat exchange between interior and exterior environments by covering and uncovering the bladder between night and day.

  6. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    In an indirect-gain passive solar system, the thermal mass (concrete, masonry, or water) is located directly behind the south-facing glass and in front of the heated indoor space and so there is no direct heating. The position of the mass prevents sunlight from entering the indoor space and can also obstruct the view through the glass.

  7. Solar water heating - Wikipedia

    en.wikipedia.org/wiki/Solar_water_heating

    When a solar water heating and hot-water central heating system are used together, solar heat will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain to provide for supplemental heat. However ...
