A hydroelectric power plant uses a plurality of windmills connected to compressed air generators to produce pressurized air. Pressurized air is used to drive water through a turbine to produce electrical power. The water is recycled and the power plant includes reserve pressurized air tanks to allow the plant to continue to operate when the wind levels are not sufficient to produce high pressure air. The power plant is designed to be operated on a continuous basis based on wind power. When the wind subsides and the reserve capacity has been exhausted, electricity can be drawn from the local utility supplier. When excess power is generated by the power plant, electricity from the power plant can be added to the grid of the local electricity supplier.

A device according to claim 1, wherein the differential comprises at least one planet-carrying annular gear rotating about the first and second shafts and coupled in rotation with a rotary portion of the braking system. 3. A device according to claim 1, wherein the differential acts as a multiplier from the first shaft to the second shaft when it is slowed down or blocked by the braking system. 4. A device according to claim 1, wherein the first and second shafts are co-rotating shafts. 5. A device according to claim 1, wherein the first and second shafts are contra-rotating shafts. 6. A device according to claim 1, wherein the braking system includes at least one disk brake. 7. A device according to claim 1, wherein the braking system includes a retarder. 8. A device according to claim 1, wherein the differential is placed together with the braking system outside an intermediate casing. 9. A device according to claim 1, further comprising an electronic computer enabling the braking system to be controlled and calculating the braking pressure that is required to adapt the transfer of energy from the first shaft to the second shaft. sing; a plate member terminating with a trailing end including a front section and a rear section inclined with respect thereto at a shallow angle; a plurality of ribs arranged in a parallel array transverse to said front section and said rear section and normal to said plate member, said ribs defining therebetween separate horizontal longitudinally extending slots for each of said spindles in movement in said closed paths, said rib having a tapered entry end engaging said front section at the front end of said slots, a center section engaging said rear section, and a tapered exit end at the rear end of said slots and projecting rearwardly beyond the pressure plate, whereby cotton traversing said slots are compressively engaged between the spindles and said ribs throughout the length of said slots for increasing cotton retention on the spindles. 6. The pressure plate as recited in claim 5 wherein said entry end is generally triangular. 7. The pressure plate as recited in claim 6 wherein said exit end is generally triangular. 8. The pressure plate as recited in claim 7 wherein said center section has a constant height. 9. The pressure plate as recited in claim 8 wherein said ribs have a planar top wall parallel to said rear section of said pressure plate. 10. The pressure plate as recited in claim 9 wherein said exit end is defined by the rear portion of said top wall and a trailing wall extending from the end thereof to the end of said rear section.
