1. The system compresses air in a steel tank using an electric motor and compressor, heating the air. 2. The hot air then cools the surrounding water in a condenser, heating the water. 3. When the air pressure exceeds a limit, it moves to steel cylinders where pistons connected to a generator shaft are used to produce electricity while further cooling the air.

6. MECHANISM
The motor rotates the shaft and forces the piston to and fro
compressing the air in the tank. As it is an adiabatic process the
internal energy remains constant and temperature of the
system(air & steel tank) rises. As the water surrounds the tank the
heat from the system spontaneously flows to it. Hot water will then
rise higher against cold water and move into the water tank and
cold water will flow down in the condenser. Ones the pressure in
the tank has crossed its limit the air will flow to the cylinder,
immersed in water, containing piston attached to a shaft connected
to a dynamo. As the pressure will increase the piston will rise,
rotate the shaft, and make the dynamo work producing D.C.
current. Ones the piston has moved to the highest position the
cooled air is then ready for use. When one of the two pistons has
raised up the other will simultaneously move down. The flow of air
in either of the cylinders will be regulated by an electrically
controlled valve. This alternate motion will help work the dynamo
and produce current. The current could be stored in a storage
battery and used via inverter.

8. PRIMARY COOLING
When the air is compressed in the tank the pressure increases
keeping volume constant. As we know ‘PV=nRT’, where ‘ΔV=0’.
Thus ‘n’(no. of moles) increases, and correspondingly the energy
associated with ‘n’ also increases. Due to the increase in internal
energy of the system, having constant volume, the energy density
increases and temperature raises rapidly. This excess of heat
spontaneously flows to the walls of the steel tank. The heat is then
absorbed by the water(in condenser) surrounding the tank. During
this process only air will be cooled and water will be heated but no
electricity will be generated.

9. SECONDARY COOLING
When the air pressure in the tank crosses its limit the air will move
in either of the cylinders pushing the respective piston up. These
pistons are connected to the shaft which makes the dynamo work
via gears. This air has to do some work to push the pistons higher.
This work is converted into electrical energy. As all the energy can’t
be converted to electricity, some energy gets converted into
thermal energy which is again absorbed by water. In this process
electricity is regenerated and air is cooled again.
