The Betz limit is based on an extremely crude model for an actuator disk. If you want to compare the performance of the product of a billion dollar industrial development program, let's at least use a respectable benchmark.

The wind turbines basically extract energy from the moving air. The Betz limit is essentially the maximum percentage of energy that is possible to extract from the air (the limit has to do with the fact that the air need to keep moving). When you use 1 blade, when energy is extracted from one part of the disk the other side is relatively unaffected. In order ...


It is less economical to harness this energy/materials. From the perspective of the company, money is better spent on their immediate business needs such as locating large resources or improving the thermodynamic efficiency of their refinery. Reasons it may be less economical include: Intermittent flow; flow may be zero for long periods, with intermittent ...


I think this is a situation of "the devil is in the details', and of course, cost. In the US, gas from a few wells would not likely be of sufficient volume; but several/many wells could be combined (detail = pipeline plan and control). There are wells, mostly Middle East that do have enough flare gas. As a point of reference the last local power gas ...
