Functional Stirling Engine with Electricity Generator!

Description

A fully functional Stirling engine that even generates electricity to light up an LED! A marvel of engineering and an excellent science demonstration. Some products allow building multiple units without increasing the price—please send a message. The price is non-negotiable! I only sell in person in the Barreiro area and nearby. I can ship by mail, but only with advance payment via MBWay, and shipping costs are borne by the buyer. #motorstirling #science #engineering #electricitygenerator #experiments #education #technology #diy #innovation #gadget
