In terms of latent heat
and efficiency, water is the best way to absorb heat for a given mass. If the cost (of containing the water) is a great concern, solids such as stone, gravel, concrete, brick, or soil may be used but will generally have a lower efficiency absorbing and releasing the heat. Water is used in automobiles and buildings for the heat transfer system (usually mixed with an antifreeze).
If volume or weight is a great concern phase change materials
such as paraffin wax have very high values of specific heat, but are expensive
. They are used to line fire proof safes and airplane black boxes
.
If the concern is absorbing solar energy
, it depends on the temperature you are aiming for.
At lower temperatures (such as heating Swimming Pools or residential air), the absorption rating is more important than the emissivity.
At higher temperatures (hot water) you will want the surface of the absorber to have low emissivity. The best surface has a high aS
/E ratio such as oxidized stainless steel, oxidized nickel, black chrome or various commercial selective surface coatings

Darker materials tend to absorb solar heat, while lighter materials reflect it.

Sorry I have no clue. I would love to help you if I could.
No
Black surfaces with large area absorb heat best (a powder for example that is black).
Darker materials tend to absorb solar heat, while lighter materials reflect it.

thetons absorb the excess heat
Simple materials can be used like black plastic or metal pipe. You want materials that will absorb heat and transmit that heat to the liquid.

The best material is copper of alumninium.
Sham wow, sponges, rags, basically any common household materials.
Good absorbers of heat radiation are like basically materials which are dark in colour. Because for some reason they tend to absorb more radiation than light coloured materials.
Glass traps solar heat. Greenhouses are made of glass so they absorb heat for the plants.
