Renewable energies in our country are an alternative for rural sectors to access electricity. Jorge Egúsquiza, shared with us one more alternative to generate power based on a gravimetric generator that uses the force of gravity on a non-equilibrium system to produce movement and generate electricity. To get an idea of how this generator works, we share with you the description of the gravimeter generator explained by Jorge himself:
“A gravimetric engine is that mechanism that uses gravity, to produce a movement. In this case the movement is produced by adding or removing a weight “and” to another weight 2 which in turn is in a non-equilibrium position, when both of them hang from a bar whose center oscillates on a pivot, with respect to a weight 1 ”
Following the following equation: Weight 1 = Weight 2 + y / 2
Let there be two weights 1 and 2 hanging from the ends of a structural bar, not solid, in the center of which there is a cylindrical hole, which contains a bearing that is attached to a pivot which in turn is inserted into a strong wall and has maximum resistance that allows you to hold both weights in the air without showing greater fatigue.
Weight 1 for illustrative purposes is 50 kilos and Weight 2 is 49 kilos. where it is true that
50 Kilos = 49 Kilos + y / 2
so y / 2 = 1 and therefore y = 2 Kilos
At this moment, Weight 1 is lower than Weight 2
Directly below Weight 1 is one end of a hydraulic lift that operates according to the Pascal principle and the Principle of incompressibility of liquids.
This hydraulic elevator, which is a liquid contained in a system of communicating vessels between two pistons.
The Piston A whose area is “a” and whose weight is 2 kilos and is in an elevated position, this is, moved upwards in its maximum stroke that is “c”, because at the other end of the elevator the Piston B whose area is “b” and whose weight is 50 Kilos including the weight of the crank that is subject to it and its maximum height or stroke is also “c”. And where it is true that:
Area of A = Area of B and therefore
a = b
what configures a hydraulic lift whose ratio is 1 to 1 ”
For those of you who do not feel comfortable following the mathematics, we share the following video where Jorge details the operation of the generator:
The unconventional gravimetric generator has been designed to provide electric power to those inaccessible areas and especially to the desert areas adjoining the sea in order to obtain drinking water from seawater. Mathematical calculations and physics studies will determine the most suitable weight ranges, heights and maximum possible yields.
