A team of engineers designed, constructed, and tested the ACES alternative water energy system using a water tank to cool a house in summer as well as heat a house in winter.
The heart of ACES is a large ice bin, shown on this page in three different versions. ABOVE: The tank can be incorporated into the basement structure of a building. RIGHT. A possible alternative to indoor energy storage is a vinyl-lined pond with a floating insulated lid. BELOW. A third distinct possibility is an insulated galvanized steel bin which can be built above grade.

This seemingly magical process — which is known as the Annual Cycle Energy System (or ACES, for short) — is not based on magic at all. Rather, it is firmly founded on two very scientific speculations.
