radioisotope stirling generator

RSG

radioisotope stirling generator

System Specs

Constructed from durable materials to house and protect the power system in extreme conditions; highly customizable design based on space or terrestrial application.

Heat from the radioisotope heat sources drives a piston back and forth inside a sealed Stirling engine. That motion powers a generator to produce electricity, significantly increasing power efficiency.

Designed with a novel fuel and shielding system to deliver high specific power from strontium-90 or americium-241.
