Active Solar Heating Systems - A solar water or space-heating system that use pumps or fans to circulate the heat-transfer fluid from the solar collectors to a storage tank subsystem. 

Active solar heating is more efficient and involves a liquid circulating through tubes. The tubes are typically encased in a box under glass and mounted on a roof. As the liquid is heated, it circulates through the pipes to heat water or the entire house (see Figure 9-5). 

Active Solar Heating. Active solar heating systems transfer a sun-heated fluid (air or water) from an exterior south-facing collector to the point of use or to a storage facility. In air systems, the storage facility is a hed of rocks, and in water systems, tanks of water. 

Active Solar Heating. Solar thermal technologies can be used for water heating, space heating, air-conditioning, and process heating. The most common types of solar water heaters are glazed flat-plate... 

The activity that characterizes a comet is driven by solar heating. As the comet approaches the Sun, jets of dust and gas erupt from active areas (Fig. 12.1), as they periodically rotate into the sunlight. The nucleus becomes surrounded by a spherical coma formed by the emitted gas and dust. Emitted gas becomes ionized due to interaction with solar ultraviolet radiation, and the ions are swept outward by the solar wind to form the comet s ion tail. A separate dust tail commonly has a different orientation, reflecting variations in the velocities of solid particles and ions. A popular term describing comets is dirty snowballs , although that description probably understates the proportion of rock and dust relative to ices.

Comets are not stable near the Sun and they are short lived in regions of the solar system where they exhibit cometary activity. Active comets are derived from two major reservoirs where they can be stored in adequate long-term isolation from solar heating and planetary perturbations. These reservoirs are called the Oort cloud and the Kuiper Belt. It appears that virtually all comets with low-inclination orbits with orbital periods less than 30 yr are derived from the Kuiper Belt while others come from the Oort cloud. 

Activity Research different ways that people capture solar energy, and what they use it for. Design a solar oven or other solar heat device. Explain how the energy is transferred from the sun through the device.
