Imagine eliminating the costly gearing of the GEC proposed multiple generators and replacing the risky rotor with much smaller, more robust and more cost effective rotors directly driving a multiplicity of smaller generators, then costs may be expected to be even lower. This is what the patented WARPTM approach accomplishes. Marketed by PE ENECO Texas LLC, it is an advanced design consisting of a stacked array of frame modules on which small wind turbines are mounted. Only WARPTM also utilises its "tower" as capture area to amplify and groom all local level winds for best and very cost effective energy recovery by small high capacity wind turbines. We invite the wind industry to take a look at its benefits.
Wind turbine rotor size is again nearing the failed size limits pursued by the US aerospace industry in the early 1980s. Consequently, an investigation by Global Energy Concepts Inc (GEC) under the wind turbine WindPACT Drive Train Study program, being conducted for the National Renewable Energy Laboratory, is assessing design options which may lead to cost and system improvements. Unfortunately, the study is limited to the nacelle-enclosed part of turbine drive trains. GEC's results so far show that multiple "smaller" generators are more cost effective than single large ones, even though they are still packaged in a large and tailored gear assembly associated with a single massive rotor.
