The 3rd Global Conference on Renewable Energy and Energy Efficiency for Desert Regions (GCREEDER 2011), supported by the Energy Center of the University of Jordan, Jordan Ministry of Higher Education and Scientific Research (Scientific Research Fund) and the Jordan Engineers Association (JEA),  was held in Amman, Jordan, April 26-28, 2011. 

Cam Follower Mechanism and energy efficiency

Submitted by Jigar Y. Patel on

You can see practical model of cam follower mechanism for clean energy.
Follower move little bit and help cam to rotate 6 times more peripheral
length. Cam can rotate 360 degree using two followers. You can get full
research at my blog at

Mechanism To Increase Energy Efficiency.

Submitted by Jigar Y. Patel on

View the figure attached. It is about using Cam for increase
energy efficiency. Cam are generally used to open and close valve of IC
Engine. I am going to show you another use. Left side initial position.
Right side final position. Redius of cam continuously decrease.Sliding
weight (MG) applied on Cam. With the help of rope weight(MG*Cos(b)) is
fixed with cam. We consider b as 45. So cos 45=.70. This fixed weight
should be 0.70 MG. Which balance the sliding weight applied on cam in
tengential direction. As sliding weight come down the fixed weight go
up. But the twist is the redius of cam decrease nominal continuously.
So sliding weight come down little bit and fixed weight go up much
more. We consider sliding weight come dowm H2 height and fixed weight

Mechanism to increase energy efficiency

As shown in figure two pulleys can rotate about their axis. Stationary
plate is simply supported on these two pulleys. Now the weight of
stationary plate applied on each pulley in vertical downward direction
is Mg/2. This Mg/2 will divided in two parts. One is tangential and
second is towards the center. Tangential part will help to rotate
pulleys and toward the center part will generate the friction.

Force is stationary and it can help to rotate pulleys at some angle.
