One important thing of a pump with a pendulum is that the work is alleviated or in simple terms it makes work rather easier when is compared with a traditional hand water pump. By the use of pendulum based water pumping system we can increase the efficiency of the plant and reduce the effort, cost of production, production time, and manpower requirement. The research done fill today is concentrated on the working and effectiveness of the mechanism only. Considering all of the advantages of the mechanism it was decided to use it for lifting water with the help of reciprocating pump such that the input to the mechanism is given by humans which is comparatively less than the effort applied by humans to lift water using hand pumps directly.
The designed pump consists of a normal hand pump and a pendulum; held together into a mechanism by a metal structure. This pendulum pump aims to provide a solution for lifting water manually, which requires a large human effort when operated continuously. It is based on a very simple principle of the pendulum, lever two-staged oscillator mechanism. With the help of this principle, the reciprocating motion of the piston in the pump is obtained using the oscillation of a pendulum. The pendulum pump was designed using different calculations and was fabricated adding frame, springs, pendulum to normal piston pump for the actual experimentation. The project purely deals with the mechanical aspect of the pendulum pump, where an experimental approach is implemented to conclude.
The pendulum, lever, and piston assembly are modeled by a separate dynamical system and then joined into the many degrees-of-freedom dynamical systems. The present work includes friction while studying the system dynamics and then simulated to verify the system’s harmonic response. The study showed the effect of the pendulum length variability on the whole system’s performance. The vertically excited parametric pendulum with variable length in the system is established, giving faster and longer oscillations than the pendulum with constant length. Hence, more and richer dynamics are achieved.
Energy requirement of the world is increasing day by day for the reason that of utilization of energy at a generously proportioned size with the population enlargement. This paper is about generating power by using a move backwards and forwards in such a way that when it swings the mechanical energy is generated and it is converted into electrical energy by pendulum and is stored in a battery.
The objective of this project is to decrease human effort to pump water and save electricity. With the help of link mechanism and spring force we can able to convert oscillatory motion to linear motion. So, the energy consumption of this system will be lowest. Use of pendulum based pump can reduce human effort, increase efficiency and save time. Its eco-friendly and maintenance and production cost is also less.
This work is based on the problem of drinking water supply in rural areas of Colombia. A water pump with a pendulum designed by Veljko Milković is cited as a cheaper way to solve this problem. For the purposes of this thesis, measurements and tests of a prototype pump with a capacity of 20 liters/h and raising water to a height of 1 meter were performed. The work below is in Spanish.
The pendulum generator deals with the power generation from the mechanical energy that has been wasted in many day today real time applications. The pendulum setup has been made, that is whenever it has been kicked off the kinetic energy of ball makes the pendulum to oscillate, generates the electrical energy.We can implement the pendulum-based power generation system in real time application wherever the vibration produced. We can implement a pendulum-based power generation system in such dynamic application we can generate power from it.
Various analyses like length ratio, weight ratio and efficiency test were conducted with the fabricated oscillator. Oscillator is constructed with a telescopic pendulum which facilitates the adjustment of length. The pivot position as well as the weight ratio of the lever is varied throughout the experiment and the optimum location and weight ratio corresponding to maximum discharge is found out. Maximum efficiency of oscillator utilized forpumping the water corresponds to 92.07%.
This paper deals with energy production from gravity. Moreover, this paper is also intended to gain the useful and green energy by using gravity effect. In this paper, two-stage mechanical oscillator with gear mechanism, cam mechanisms and dynamo is fabricated to conduct the experiment. The process of this machine is that when the pendulum is applied with the input energy, the pendulum oscillates on the free moveable pivot point and this oscillation effect can move the lever arm to produce the second oscillation motion as same as seesaw arrangement system. Meanwhile, at the other edge of the lever arm, the output can be available as impact effect. This effect can be used as the output energy to drive the other mechanisms such as hammer, water pump, electric motor, and generator for the useful energy.

This paper discusses the significanceof a pendulum pump which can be used as a complementarydevice for pumping water and is made to replace hand pumps. One vitalqualityof a pump with a pendulum is that the work is alleviated or in easyterms it makes effortrather easier when is compared with a conventionalhand water pump. It is due to this underlined qualitywhich enables the pendulum pump to be used as an efficient mode in the irrigation of lesserlots, water-wells and can also be used in extinguishing fires even by agedcitizensand children.
The main importance of a pendulum pump is that the initiation energy for starting the process of pumping, swinging of the pendulum, is considerably minimum when compared with the work required to operate hand pumps. The most important feature of this is: The effect of creating the free energy in the device made of: 1. Oscillating pendulum-lever system, 2. System for initiating and maintaining the oscillation of the Pendulum
This project is indented to develop a free energy device that works on gravity. A simple mechanism with new mechanical effects represents the source of clean energy. This gravity machine has only two main parts: a massive lever and a pendulum. The interaction of the two-stage lever multiplies input energy into output energy convenient for useful work.
As we know nowadays the main problem in the rural areas of our country is electricity or energy. So we have decided to make a convenient and efficient machine which is capable to generate electricity and supply it to the rural parts of the country. This is the machine whose objective is to generate electricity from Gravity Energy which is easily available. Input to this machine is movement of the pendulum due to gravity, which is freely available. And this motion of the pendulum is converted into usable mechanical or electrical energy. This way we get continuous energy.
There area lot of availability of mechanical energy in the environment. This mechanical energy can be converted into other form of energy like electrical energy. Here we developed a pendulum motion based power generator that sustains its motion with low maintenance providing voltage output peaks from a reciprocating mechanical structure. The reciprocating effect of our device is enhanced by using gear mechanism that is composed of shaft with a dynamo. his paper is a platform of developing a sustainable, low maintenance system to generate electrical energy.

Hand water pump is the best solution to lift the water without using electricity. But it requires a large human effort which is not feasible for long time. When we need the supply of water continuously this is not the best solution to lift water continuously. So Hand water pump with pendulum is the best solution for pumping water without using the hand pump. This is providing alleviation of work, because it is enough to move pendulum occasionally with little finger to pump water, instead of large swing.
This paper discusses the importance of a pendulum pump which can be used as a supplementary device for pumping water and is made to replace hand pumps. One important feature of a pump with a pendulum is that the work is alleviated or in simple terms it makes work rather easier when is compared with a traditional hand water pump. It is due to this underlined feature which enables the pendulum pump to be used as an efficient mode in the irrigation of smaller lots, water-wells and can also be used in extinguishing fires even by old people and children.
Hand water pump with a pendulum is a very simple solution for pumping water. It provides alleviation of work, because it is enough to move the pendulum occasionally with a little finger to pump the water, instead of large swings. Work is alleviated because easier, long-lasting and effortless use of the hand water pump has been enabled. Input energy for starting the process of pumping, in form of occasional pushing of the pendulum, is much less than with typical hand pumps. The operation of the machine is based on forced oscillation of the pendulum, since the axis of the pendulum affects one of the arms of the two armed lever by a force which varies periodically.
The purpose of this project is to explain the practical functioning of two-stage mechanical oscillator, i.e. to demonstrate the possibility of practically generation of excess energy in the form of electrical energy by using two-stage mechanical oscillator. Our object is to develop such mechanism which is used in hand pump for rural application with minimum investment. The project would discuss the dynamics of the body when a gravitational force acts upon it.
We initialized our project with an objective to reduce the human effort. The purpose of sucking the water from the ground, they were installing the piston pumps on every village. The reason behind the choice of piston pump is due to its less maintenance and less installation cost. But we were planned to replace that reciprocating motion with an oscillating motion. This method may be an already existing one, but the way of application is quite different in our project. Hence according to us by slight modification of an existing piston pump for adapting to the oscillating motioned piston pump, we can obtain the required amount of water with a minimum effort and with a low cost.
This paper consist of working of reciprocating pump which is driven by a compound pendulum. It provides the energy required to lift the water from a tank placed approximately several meter below the ground level. Basic application of the mechanism will be for watering the garden which will be operated by means of operation opening and closing of entrance gate. Paper consists of basic concept, design of pump and compound pendulum mechanism and fabricationed model. The concept can also be implemented in the rural areas, having the problem of electric supply. We aim at making a prototype for providing some mean for pumping of water by the pump which requires less human efforts, considering cost effectiveness, easy to operate and portable mechanism
Our project is such an attempt which tested the ongoing research on the over unity power generation based on the experiments of renown Ser-bian inventor VeljkoMilkovic and we intend to specify about how the prototype developed in such a man-ner would throw light into very interesting scientific investigations carried upon invisible energies existing around us.
Energy harvesting is an emerging technology that derives electricity from the ambient envi-ronment in a de-centralised and self-contained fashion. Applications include self-powered medicalimplants, wearable electronics and wireless sensors for structural health monitoring. Amongst thevast options of ambient sources, vibration energy harvesting (VEH) has attracted by far the mostresearch attention. Two of the key persisting issues of VEH are the limited power density comparedto conventional power supplies and confined operational frequency bandwidth in light of the random,broadband and fast-varying nature of real vibration.
In the arena of vibration energy harvesting, the key technical challenges continueto be low power density and narrow operational frequency bandwidth. While the conventionhas relied upon the activation of the fundamental mode of resonance through direct excitation,this paper explores a new paradigm through the employment of parametric resonance. Unlikethe former, oscillatory amplitude growth is not limited due to linear damping. Therefore, thepower output can potentially build up to higher levels. Additionally, it is the onset of non-linearity that eventually limits parametric resonance; hence, this approach can also potentiallybroaden the operating frequency range. Theoretical prediction and numerical modelling havesuggested an order higher in oscillatory amplitude growth
This paper presents the conceptual mechanism to run the reciprocating pump by the two-stage oscillator. It provides the energy required to lift the water from a tank placed approximately 2.5 meter below the ground level. Basic application of the mechanism will be for watering the garden which will be operated by means of opening and closing of entrance gate. Paper consists of basic concept, design of pump and two-stage oscillator mechanism and fabrication of the model.
