1. A power system for providing an uninterruptible power supply comprising:
- a first generator means for supplying energy to a primary load;
a second generator means connected to an electrical utility, said first and second generator means being connected by a common shaft, said first generator means being electrically isolated from said electrical utility;
prime mover means connected to said common shaft, said prime mover means for supplying mechanical energy to said shaft; and
controller means interposed electrically between said second generator means and said secondary external load, said controller means causing said second generator means to become disconnected from said secondary load upon interruptions in said secondary load.

Abstract
A power system for providing an uninterrupitible power supply comprising a first generator connected to a primary external load, a second generator connected to a secondary external load, and a prime mover connected to said first and second generators by a common shaft. The first generator is electrically isolated from the secondary external load. The prime mover is an internal combustion engine that supplies rotational movement to the common shaft. The secondary external load is an electrical utility. A thermal recovery system is connected to the internal combustion engine.
