Westergaard Solutions

HydroMINE is a disruptive and elegantly simple modular system with a relatively small internal propeller driven by pressure from a stationary hydrofoil structure to a separate, internal flow stream. The internal propeller drives an ordinary electric direct drive generator. The size of the stationary HydroMINE hydrofoil structure is comparable to an equivalent ordinary rotor of the same swept area producing a similar amount of energy. The external floating structure is passive, only yawing slowly with the ocean tide or river flow direction. The internal propeller is isolated from debris and…

Western Research Institute

Western Research Institute will explore technologies based on pyrolysis (thermal conversion) and hydrocracking (a chemical process that upgrades low-quality, heavy gas oils) to convert waste, low-value plastic, and paper polymers into high-energy liquid products suitable as fuel, refinery feedstock, or feed for chemicals manufacturing. The pyrolysis technologies involve heating the polymers in oil media to a temperature high enough to break the chemical bonds to produce a liquid product. The pyrolysis may also be applied to low-level conversion of the polymers to yield a slurry feed for a…

A Z-pinch fusion device has an electrical current driven through the fusion fuel, creating self-generated magnetic fields that compress and heat the fuel toward fusion conditions. While a Z-pinch with no equilibrium flows has rapidly growing instabilities that disrupt the plasma within nanoseconds, the Z-pinch can be stabilized if an axial plasma flow varying strongly enough with radius is introduced. This sheared-flow stabilized (SFS) Z-pinch may be the simplest and most compact of all known controlled-fusion approaches, as it does not require magnetic coils nor any external heating systems…
