Lift working with Advantage of Gravity and Density difference

Project Abstract / Summary : Introduction:
In present days Escalators are extensively needed and used because of aggressively emerging multi floor buildings, apartments, Industries, public sector constructions etc. Lots of energy is being used by them, we need to reduce the energy being used by them. Our project deals with that area.

Basic Principle:
Using of density difference between lift (object to be lifted) and medium in which it is operated we can reduce energy. Lesser the density difference between lift and medium, lesser will be the energy required to lift the object. For example energy required to lift an object in liquid medium is lesser than in air medium.
Lifts has commonly two strokes moving Down and Up
While coming down: use of gravity:
• In this case, lift consisting of load is having density
greater than water, hence lift slides downward in the
cylinder container.
•Lift having density slightly greater than water will fall under gravity in water medium.
• Then water flows into the opening provided at the centre of the lift as shown in fig.
•This is the only way for water to get displaced.
• Hence the lift will come down slowly.
•we need to maintain the constant velocity of lift around 1.5 m/s.
•Here the amount of water flowing in the opening provided is directly proportional to falling velocity of the lift.
•Therefore we can control the velocity of lift by controlling the flow rate i.e by controlling the diameter of the opening.
• For controlling the diameter of the opening provided and flow rate, flow control valve can be used.
• When the lift starts accelerating due to gravity, we need to reduce the flow rate by reducing the diameter by mechatronically operated flow control valve.
•For controlling the diameter of the opening, we can also use manually operated valves, which need to be operated by operator regularly.

While going Up:
•We Know that lifting of object in the water is easy i,e requires
less energy than in air because of relatively lesser density difference
•Lift without load will become less denser than water which
brings lift up due to buoyancy force..
• If people enters the lift we need to lift up the lift which can done by simple conventional techniques chain drive or rope drive connected to motor running at constant velocity.
•Which also uses lesser energy than the conventional lifts which are being used now.
•In case only if down stroke is required we can operate this system with total energy free.
Total free energy system can be achieved by proper design.
• When lift is at top position the density of (lift + humans/materials inside it) is higher than the water or fluid used and lift comes down with free energy due to its weight.
• When humans/materials goes out of the lift the density of the empty lift should become lesser than water then lift goes up naturally due buoyancy force.
Advantages:
• If we fix the dynamo in the hole or pipe, using the flow rate in pipe we can generate electricity in both Down and Up strokes of the lift, since water has only that way to displace for motion of the lift.
• It is a flexible system that, we can utter velocity of the lift depending on type weather lift is used for humans or materials of different kind by uttering the program if mechatronic system is used for controlling velocity during downward motion of the lift.
• Uses gravitational energy to its operation which is absolutely free.
• Generates electricity from gravity which is absolutely free from pollution.

Sir, done mini demo and succeded upto certain extent.

Why did you choose to work on this project topic : Sir I am interested in perpetual motion mechanisms which are not possible but it is important to semi perpetualize the systems by using free energy like gravitational energy, buoyancy force, which will definitely reduce the energy required by the system, and present lift systems consumes more energy during upward stroke and even in a downward stroke, which can be overcame by this idea. These are the reasons which make me to work on this project.
