What materials conduct the most solar energy?

Question by Corneille Alphonse: What materials conduct the most solar energy?
I was assigned to create a solar power cooker, therefore I need to know what materials conduct the most solar energy.

Best answer:

Answer by J S
Air conducts solar energy because it allows it to pass through.

For a solar cooker you want to deflect or concentrate the solar energy, and maybe focus it onto something that absorbs the energy to create heat.

To deflect, you need a reflective surface, something with low emissivity and high reflectivity.
To absorb you need a dark or rough surface, high emissivity, low reflectivity

  1. Silicone is prolly your best bet for such a project. However, if you
    have to actually ‘eat’ the food, I’d try using small mirrors angled
    against one another, sort of a mirror chamber.

    You can buy really cheap mirrors at the 99 Cents store or
    Dollar Tree. Good luck with your project :)
