A memory alloy spring engine includes a spring (1) made from a memory alloy, a driving stem (6) and a heat resource. The memory spring (1) is connected to the driving stem (6) and configured to move the driving stem (6) when being compressed and deformed by an external force, to restore to an original shape after being compressed and then heated, and to move the driving stem (6) again after being cooled and then compressed and deformed again so as to move the driving stem (6) up and down along therewith in continuous repeating cycles. The memory spring is equipped with a polyhedral glass ball (3), the polyhedral glass ball (3) is configured to collect sunlight from different angles and to conduct solar heat to the memory spring (1) so that the memory spring is heated and thereby restored to the original shape. The engine may utilize natural heat energy (solar energy or geo-heat) and combustible fuel alone or in combination to generate electricity according to different locations or different times.
