| 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.
