RECOVERING HEAT ACROSS THE GLOBE

Air energy and heat storage system
Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal. [pdf]
Can the back of the sun generate electricity
When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of electricity.. When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of electricity.. An MIT team has developed a novel system for capturing and storing the sun’s heat so it can be used to generate electricity whenever it’s needed. The new system is simple, durable, and inexpensive.
