How Does This Energy Conservation System Work?

Click For Summary

Homework Help Overview

The discussion revolves around a proposed energy conservation system involving a ball, a turbine, and a generator. The original poster questions how this system adheres to the principle of conservation of energy, while also raising a separate question about the dynamics of a rider on a stationary versus moving bike.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the mechanics of the energy system, questioning the feasibility of pushing the ball through the valve without work. There is also consideration of the energy loss involved in the turbine's operation.

Discussion Status

The discussion is active, with participants offering differing opinions on the energy dynamics at play. Some guidance has been provided regarding the energy loss in the turbine, but no consensus has been reached on the overall functioning of the system or the rider's question.

Contextual Notes

The original poster expresses uncertainty about their English and acknowledges previous discussions on the rider's question, indicating a search for clarification on these concepts.

A system is developed as shown in the diagram attached. The ball is initially given a push so that it falls onto a turbine connected to generator which produces electricity. After rotating the turbine the ball fall down a narrow tube with a valve into the water again the ball rises again and is again given a slight push and the whole process is repeated again and again. In this way energy is being "created". The question is: How does this machine obeys the principle of conservation of energy?
Secondly, Why does a raider raiding a bike falls when the bike is stationary but does not fall when its moving? I know that this question has been asked before but I can't find it.
Any help will be appreciated.:smile:
(Pardon me for my bad english.)

Do you think it is possible to push the ball through the valve and into the water without doing any work?
 
No I dont. In my opinion the KE of the ball will be used to open the valve...
 
And, of course, the ball will have lost some of its energy in turning the turbine.
