Florida-based Matteran Energy has developed a new technology using blazing-hot solar energy to produce cool, refreshing air. Pricey photovoltaic cells? I think not! Matteran's solution uses thrifty thermal-collection technology, heating a synthetic fluid with a very low boiling point (around 58 degrees F) to create steam that drives a specially designed turbine. This technology is not so new, however Matteran's developments will have significantly increased the system's efficiency for small-scale use, providing relief from the heat and from Con Edison.
