DIY Solar Absorption Cooler

Solar energy is an increasingly popular way to cut energy costs, cool off houses and protect the environment due to it's reliability and carbon-free efficiency. Solar absorption cooling harnesses the power of the sun to provide air conditioning and cooling fan power much like traditional energy. Building a solar absorption cooler can be done using basic materials, yet the benefits can be enormous. Solar cooling can lower your energy bills while protecting the Earth's natural resources and environment at the same time.
