Old Energy From Still Air Photo
I happen to dig up an old photo from Dec 21, 2004 when we did our first public demonstration of Lead-out/Bring-in energy in Tai Po, Hong Kong.
I was using the supersoaker water gun to explain that Energy from Still Air was used. Initially, I was hoping to use the water rocket but the supersoaker was easier to carry.
The adiabatic expansion of air (rapid expansion of the compressed air) will lower the temperature of the air and water gun. That thermal energy accounts for the extra energy other than pumping.
The Hidro uses similar energy.
