Cooling is set to become the world’s single largest use of electricity in buildings by 2050. The majority of new demand will come from emerging economies with hot and humid climates and a growing middle class. As a result, air conditioning represents one of the largest risks to our climate.
One of eight finalists in the Global Cooling Prize, Transaera uses a novel sponge-like material that grabs moisture from the atmosphere, enabling their air conditioner to cool the air more efficiently. The AC then uses the heat it generates—instead of wasting it—to dry the material for the next cycle.
