Dry Friction and the Milkovic Effect

[Merg]

Pendulum Gravity Team from India   

Student project: Veljko Milkovic's Pendulum Pump (replica)     

Video #1: Gravity Energy Machines
This project is made by Harshil Padia, Amey Patel, Jatan Desai and Vinay Sawant who are the students of Shri. Bhaghubhai Mafatlal Polytechnic  from the Department of Mechanical Engineering. This is their last year Diploma Project. This video is intended to show their work from last 2 years.  They are still working on this project...

Page is all about the project we are doing called GRAVITY ENERGY MACHINE
Our Present Project is all about "THE PENDULUM PUMP". It's made with the objective to reduce the efforts of farmers to draw water using hand pumps. This project is basically an attachment to conventional hand pumps which reduces the efforts required to draw water. This is achieved using double oscillating mechanism which gets advantage of gravity and inertia of its own pendulum to draw water. Mission in to make a device that efficiently utilizes the energy available from gravity.

It is interesting to be recalled and noticed that the collision of the ball and cart itself, in this Veljko Milkovic's demonstration of the pendulum cart, does not dissipate the huge energy.

Newton's cradle is the right proof for this.

It's demonstrated that a soft swing of the pendulum is way more efficient than the sudden impact on the carts wall. The impact has great losses, but that is caused by the material of the wall and its fragile construction. If the wall didn't move or absorb at all, the ball would bounced back and forth several times causing the cart to travel just as far as the pendulum demonstration does.
