2. Space Shuttle thermal protection system - Wikipedia

   en.wikipedia.org/wiki/Space_Shuttle_thermal...

   The light gray material which withstood reentry temperatures up to 1,510 °C (2,750 °F) protected the wing leading edges and nose cap. Each of the orbiters' wings had 22 RCC panels about 1 ⁄ 4 to 1 ⁄ 2 inch (6.4 to 12.7 mm) thick. T-seals between each panel allowed for thermal expansion and lateral movement between these panels and the wing.

3. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   t. e. A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non- water heating devices such as solar cookers or solar air heaters.

4. Multi-layer insulation - Wikipedia

   en.wikipedia.org/wiki/Multi-layer_insulation

   The metal coated plastic layers and the scrim separator are visible. Multi-layer insulation ( MLI) is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics. Also referred to as superinsulation, [ 1] MLI is one of the main items of the spacecraft thermal design, primarily intended to reduce ...

5. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   Even though the HTF contains glycol to prevent freezing, it circulates hot water from the storage tank into the collectors at low temperatures (e.g. below 40 °F (4 °C)), causing substantial heat loss. A drainback system is an active indirect system where the HTF (usually pure water) circulates through the collector, driven by a pump. The ...

6. Seasonal thermal energy storage - Wikipedia

   en.wikipedia.org/wiki/Seasonal_thermal_energy...

   A number of homes and small apartment buildings have demonstrated combining a large internal water tank for heat storage with roof-mounted solar-thermal collectors. Storage temperatures of 90 °C (194 °F) are sufficient to supply both domestic hot water and space heating. The first such house was MIT Solar House #1, in 1939.

7. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   Hot water to domestic appliances. A small tank water heater. Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.
