(Answer) (Category) The Solar-AC FAQ : (Category) Solar cooling examples : (Answer) Solar intermittent ammonia absorption icemaker
The ISAAC (intermittent solar ammonia absorption cycle) is basically just an oversized Icyball with long cylinders in place of spheres for the evaporator and absorber chambers. The solar collector is a parabolic trough. The design is based on Donald Erickson's work. Erickson, I think, heads Energy Concepts Company which produces ISAACs for developing countries. --Art

An ISAAC was featured in Home Power Magazine #53. This online version of the article (in PDF format) is a good quick read with pictures.
