Generation of Electric Power, Harnessing

Atmospheric Pressure

Raj Kumar Parashari

Abstract— This paper reports a metod / technique to produce huge amount of electricity by harnessing atmospheric pressure .It also discusses unique features and further scope of the project .Calculations suggests that power generated is large enough to meet the need of electric power for the globe .It should also reduce effect of global worming .

Index Terms— Atmospheric pressure, Bernoulli’s theorem, Electric generator, Electric power, Efficiency, Partial vaccum, Pressure difference,

1 INTRODUCTION

ith the continuing damand of electric power ,it has be- come mandatory to look for alternate sources of energy
.Sun energy and all of it’s derivative ways such as wind energy ,ocean energy etc could provide only limited and spe- cific use baring hydroelectric power .Hydroelectric power which has it’s own limitations such as amount of rain fall , large catchment area , cost of making dams etc. What I feel is that solution lies within ever lasting our own atmosphere.

A & B vertical towers filled with liquid. M & N are AC – generators.
To pump X – Water coming out through the outlet will be col- lect in a large container and then will be lifted up with the help of pump X to recharge vertical towers.
To pump Y –This inlet will be used to pump out air / gases within the metallic box.

(In recharging)
If we take efficiency consideration of all pumps and other factors such as non ideal nature of water, we expect net useful
power produced ≈ 1 MW from single unit with ten towers. So
produced electricity will enough to light ~ 500 houses with
requirement 2.0 KW each.
(c) Water that collects within the chamber will not be able to come out all by itself. To solve this problem, we will install two such systems side by side. When first system is active oth- er will be idle. Once the water reaches up to turbine level in first system, the electronic gadgets will perform following ac-
tions :—
Note: — To reduce evaporation rate of water , we can use suitable liquid at appropriate temperature and we will need to run vaccum pump continuously for the evacuation of evapo- rated gases.
Note: — the height of supports holding the dynamo should be
increased.
* This number can vary as per requirement (Calculation shown for 10 towers).
** For radius of the pipe = 8cm and velocity = 25 m/s, so the
mass of water entering the chamber per second = A v ρ

(i) Should switch off first system and switch on second system
(ii) Should open valve V1 (attached just after pump Y; not

shown in the diagram) so that air gushes in to the chamber and helps the water to evacuate all by it self .Once it is done create vaccum again. All this should be done before water lev- el in second system reaches up to the turbine height .Now the cycle can be repeated .

2 UNIQUE FEATURES UTILITY AND FURTHER SCOPE

(i) Relatively pollution free production of power
(ii) Low cost /unit of electricity
(iii) First time atmospheric pressure harnessed for the production of power.

3 UTILITY AND FURTHER SCOPE

(i) Such type of systems can be installed any where within the city as per requirement.
(ii) Above I have illustrated using one example. (In general
power delivered to the turbine will be proportional to cube root of height and square of radius of pipe. For improving result we can increase radius or height of towers or both)
(iii) Further similar system can be installed deep inside sea to
harness power.
(iv) Work is continuously done by the atmospheric pressure and hence will help to reduce global worming.
