Carbon-Based Magnets

Virginia Commonwealth University (VCU) is developing a new magnet for use in renewable power generators and EV motors that requires no rare earth minerals. Rare earths are difficult and expensive to process, but they make electric motors and generators smaller, lighter, and more efficient. VCU would replace the rare earth minerals in EV motor magnets with a low-cost and abundant carbon-based compound that resembles a fine black powder. This new magnet could demonstrate the same level of performance as the best commercial magnets available today at a significantly lower cost. The ultimate goal…

Crosslink Aerogels

Virginia Commonwealth University (VCU) will develop innovative methods to produce aerogel-on-glass windowpanes for window retrofits. Silica aerogels are porous materials that can be used to control heat transfer across windows. However, widespread use of silica aerogels in windows has been limited by their mechanical fragility, difficulties with transparency, and high manufacturing costs. The team will use newly developed cross-linked aerogels that significantly improve the mechanical strength and durability of aerogels. Aerogels are typically produced through either air drying or…

Capability in Theory, Modeling, and Validation for a Range of Innovative Fusion Concepts Using High-Fidelity Moment-Kinetic Models

As fusion machines move toward a burning-plasma regime, liquid first walls and blankets may be needed to handle first‑wall heat-flux, reduce erosion, and eventually to convert energy and generate tritium fuel. Repetitively pulsed fusion designs may require extreme electrode survivability, where the electrode may be solid, liquid, or a combination of both. It is critical to address how plasma dynamics in the fusion plasma will couple with both liquid-metal and electrode-material dynamics for fusion energy to become realizable. This Capability Team will use fluid and reduced kinetics, including…

Advanced Stirling Power Generation System for CHP

West Virginia University Research Corporation (WVURC) and their partner, Infinia Technology Corporation, propose to demonstrate an advanced Stirling power generation system for residential CHP applications. A Stirling engine uses a working gas housed in a sealed environment, in this case the working gas is helium. When heated by the natural gas-fueled burner, the helium expands causing a piston to move and interact with a linear alternator to produce electricity. As the gas cools and contracts, the process resets before repeating again. Advanced Stirling engines endeavor to carefully manage…

Sheared Flow Stabilized Z-Pinch Performance Improvement

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…
