Solution to the World’s most Critical Problem : Energy Crisis

2. World is suffering from the shortage of energy.
We are actually just totally ignoring the most
available source of energy present in our
environment.
1. Gravitation
2. Buoyancy
I am going to show how these above mentioned
energy sources can be used to generate electricity.
OVERALL IDEA OF THE PROJECT

3. Electricity
Cutting of
Magnetic
flux
Spinning
Movement
of body
External
Force
Basics to produce electricity
The fundamental way of
generating electricity is by
changing the magnetic flux
density.

4. So what we come to know
• We need to spin something (for changing
the magnetic flux density) to produce
electricity
• It may be through water vapors, water
fall, wind or any form of energy which
pulls or pushes

5. Main Block Diagram For the Project
Those green arrow is showing the movement of the wire. This up
and down motion can be converted into circular motion to spin
turbine for producing electricity.

6. How will it work?
1. In the beginning, the whole system will be
in a equilibrium that means the downwards
force (due to the weight of block) is equal
to the Buoyancy of the balloon.
2. At equilibrium situation the weight of the
block will be called Critical Weight(say W)
3. If we increase the weight of the Block by
adding a small object , then Balloon will go
to downwards.

7. How will it work?
4. If we decrease the weight of the Block by
removing that small object , then Balloon will
go upwards.
5. Thus Buoyancy is doing the trick.
6. Hence we are getting a up-down motion and
with that we will rotate a turbine and produce
electricity.
7. We just need a small mechanism for adding
and removing the small object from the block.

8. Principle driving force
The mechanism for adding and removing the
small object from the main block(W) is our
principle input force.
Other heavy lifting is done by the our two
counter forces which are
a. Gravity
b. Buoyancy

9. One Key Thing To Note
• Larger the height of the water tank less the
consumption of driving power
Practical Application of this project is fully
possible and without occupying much space,
this gravity-buoyancy-electricity can serve
electricity to people in very less price
comparing to others.

10. Benefits
• Minimal amount of driving forces ( power )
needed comparing to other sources of
energy. A simple motor driven on solar
energy will do the work as a small object
need to be seated/removed upon the main
block(W)
• No pollution to the environment
• Can be made in small units and stacked one
upon another units. So less space
consuming
• No wastage of any resources

11. Problem solved by this project
• We know the world is suffering from
energy crisis.
• This project is trying to solve this matter
without using any fuel and other
conventional or non-conventional energy
sources.
Uniqueness
• Still there is no use of gravitation and
buoyancy to produce electricity
