Use this if you want. It will decrease your manufacturing cost.

Mechanism that 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.

Mechanism that increase energy efficiency.
 As shown in figure sliding plates can slide over fixed plates.

Stationary plate is simply supported horizontaly on sliding plates. Lubrication is provided at contact surfaces of stationary plate and sliding plates. Weight or load or force (mg) is applied at center of stationary plate. This load is equally devided and applied on each sliding plate in vertical downward direction (mg/2). This mg/2 cos(alpha) helps  sliding plate to slide in nearly downward direction.

            Figure is in cross section. as shown in figure, there are two cases. in each case there are two pulleys of same diameter. each pulley is of exactly circular shape.In first case 50 k.g weight is fixed with each pulley as shown in figure. The center of each pulley is fixed. Between these two pulleys there is a stationary plate. plate will remain stationary, while rotating the pulleys because centers of pulleys are fixed. 100 k.g weight is put on this plate. The force or weight of plate is applied on these two pulleys in vertical downward direction. now we try to rotate slowly first pulley in clockwise direction and second pulley in anti clockwise direction. lubrication is provided between the contact surfaces of stationary plate and pulleys.
In second case two pulleys of same diameter. 50 k.g weight is also fixed with each pulley, but there is no stationary plate and 100 k.g weight. Now we try to rotate slowly first pulley in clockwise direction and second pulley in anti clockwise direction.
As free body diagram in first case we can rotate pulleys using less moment of force. we can lift mass using less energy.

1. In case 1) the moment necessary to rotate each pulley is

m=(-g/2cos(bita)+g1*cos(alpha))*r
where:
g is weight of plate (=100 kg)
g1 is given weight (=50 kg)
alpha and bita are angle of rotation of each pulley
r is radius of pulley
2. In case 2) weigt of plate g=0

Uses and Advantages:

1. It will decrease manufacturing cost.

2. It will decrease electricity Bill.

3. It will help to reduce green house effect.

4. It provides clean energy.

5. It is cheap and available at every place.

6. It can use for both linear as well as for circular motion also.

7. It will improve quality of people’s life by giving clean and cheap energy.

8. It will help to reduce carbon dioxide in environment.
