Abstract
An engine driven by an expanding gas and utilizing a liquid seal in an inexpensive construction which by virtue of the low temperature differential required between inlet and outlet gas is particularly well adapted for use in converting collected solar energy to mechanical or electrical energy. The engine may also be adapted for use as a compressor.
