Answer to Question 1

You should not invest. This is what is known as a perpetual motion machine. The
second law of thermodynamics says that this cannot work as advertised. There is energy in
the air, but for a thermal engine to work, there must be a low temperature reservoir and a
high temperature reservoir. There is just one reservoir here, so the machine could not work.

A
