Periodic Vortex Wind Generator

This project has both pure research and applied device components.

The pure research agenda is related to the topoiesis [More] research. In that case, we focus on formal support for the complex logics we encounter in the real world. The most common examples come from the “soft” worlds of human behavior, narrative as a basis for cognition and analogical reasoning. But there are non-human-related problems in the physical world that are equally challenging and amenable to the same approach. One problem area is concerned with biomolecular dynamics where the system has non-linear behavior, and any individual cell, molecule or such exhibits quantum behavior with apparent non-monotonic “reasoning.” Existing abstractions are rather poor at modeling key dynamics in this domain, and two-sorted, categorical logic systems can fill that need.

An analogous problem occurs at a more human level regarding behavior every bit as complex: the behavior of wind as it flows amidst complex objects. We have had some very good modeling tools that get us part of the way there, but they just cannot handle many of the non-linear complexities. So we have extensive test environments for say, new aircraft and aircraft engine designs, like SCRAM jets. We developed an early form of topoiesis to address this problem, thinking of vortices and virtual vortices as collaborative agents. It seems to provide a new set of tools for these problems in compressible fluid structures.The more advanced version of this theoretical work is contributing to the Eidetic Streamer [More].

The “applied device” part of this project concerns wind turbines for generating electricity. The current method has wind affecting a shaped blade which turns. An axle drives a generator. Disadvantages of this approach are: expensive towers are required; the works are at the top of the tower and therefor hard to maintain; the turbine requires a minimum breeze, below that it will not turn; the turbine has to shut down when the wind is too high, discarding that power; birds are killed (already in the millions); turbines respond slowly to a change in wind direction or speed, throwing away energy. The harder the wind blows, the faster the axle turns, making direct AC power infeasible. Even in a perfect, frictionless turbine with a perfectly efficient generator and constant wind at the optimum speed, the efficiency is very low; 17-31% of the energy is captured. In the real case, it hovers around 3-5%.

Our design is superior in all these respects [More].
