RIM DRIVE ADVANTAGES
No Gear Box: Turbine produces power in wind speeds from 4 m/s through 20 m/s without the use of expensive gear boxes.
Weight is Down Low: The liquefaction system, compressors, generators, etc. do not put pressure on the tower system since they are located at the base of the tower.
No Cranes Needed: There is no need for heavy cranes to install the machines since they are assembled at ground level.
Drives up to 36 components: Each blade can direct drive up to 36 individual components simultaneously.
Long Service Life: 100 year service life on totally recyclable marine grade aluminum blades.
Easier to Maintain: The blade lowers to the base on its own power for repairs or maintenance
More Powerful: Blades are more powerful per square meter of blade swept area than existing machines.
Less Turbulent: The semi-open center design creates less downstream turbulence and allows for installation of more units per square mile
Scalability: Stayed blade systems are scalable to multi-megawatt sizes (possibly > 100MW per machine)
Less Capital Investment: Requires much less capital and O & M cost per KW than conventional three bladed machines.
Locally Available Components: All components of the system are locally available in most countries.
Flywheel Effect: The system has a flywheel effect that absorbs wind gusts, eliminating most turbulence problems.
No Bird Problems: Slower operating rpm and multiple blades means no bird or bat kills.
