A gearbox can be placed between the crankshaft and the power generator, to increase the rpm of the second shaft. The main use of motor A is not to generate electricity but to synchronize the rotation of the crankshaft to the chosen speed. The vacuum pump does not need to be constantly on, maybe a couple of times a day for 1 minute or less to restore vacuum to a specific value. The liquid compartments can be at the upper half to facilitate the flow of the liquid inside the units due to the weight. The device works 24/7, so home batteries could be charged during night to collect and store surplus power from just one device. Other units can be applied, this would probably need the use of a second belt.

PROJECT FOR THE PRODUCTION OF ELECTRICITY
The aim of this project is to generate electric power using a device (O.D.) made of a
container, a crankshaft, a liquid pump, vacuum pump, and units which have a function
similar to that of a piston, any fluid can be used which is most appropriate, maybe a low
viscosity oil.
DESCRIPTION:
The container is divided into compartments, in this example there are 8 but it can be more.
One set of compartments are filled with liquid, the others are partially filled with liquid but
contain also vacuum in the upper part.
The number of units can be any, in this example there are 4, they are positioned on the top of
the container. Each unit has a piston which is linked to the crankshaft through a connecting
rod, their function is to move the crankshaft, which causes the rotation of a rod linked to a
power generator producing electricity which is transferred to a battery.
When a piston moves upwards it causes the liquid to pass inside the unit from the
compartment at the back.
The downward movement of each piston is a consequence of the action of the vacuum
contained in the compartment in front of the unit, the pressure exerted by the air outside the
container moves the liquid present inside the unit into the compartment containing the
vacuum. This pressure causes also the upward movement of the other pistons.
The movement of the crankshaft can be also assisted by a motor (motor A in the images)
which keeps a constant speed.
The passage of the liquid in and out of each unit is allowed by means of a shaft which has a
hollow space and is located at the base of each unit, this shaft is connected to a gear which in
turn is connected to a synchronous belt which is moved by a motor (motor B in the images),
which rotates in alternating sequence in opposite directions, so that each time the belt moves
it causes the rotation of these shafts by 90 degrees first in one direction then in the opposite;
the time between one rotation and the other equals to the time that the piston takes to
complete one upward or downward movement. When half of the pistons move upwards the
other half move downwards.

2. When a piston is moving upwards the hollow space of the shaft is facing the compartment at
the back of each unit and the liquid flows inside it and in the unit; and when the piston is
moving downwards the hollow space of this shaft faces the compartment containing vacuum,
in front of the unit.
To prevent the liquid to completely fill also the compartment containing the vacuum a pump
moves the liquid from these compartments to those at the back of the units (in the example
shown specifically from compartment 1 to compartment 2, 3 to 4, 5 to 6 and from 7 to 8).
A second pump is also used to form the vacuum inside the compartments.
