A demonstration of one of the first 19th century attempts to
produce an environmentally sound economic and efficient power
source. The heat from a small candle sends this Stirling Engine
model into oscillation almost immediately. Easy to construct this
unit very visibly demonstrates the Stirling Engine principle. A
test tube acts as the cylinder and four marbles work as a transfer
piston. As air is heated on one end of the transfer cylinder it
causes the air to expand and move into the cooler end of the
cylinder. Here the air cools and contracts causing the cylinder to
lower and the cycle begins again. Instructions included.
