Nano to begin drilling next week in Illinois
It’s been a good month for Nano Nuclear in the state of Illinois. On October 7, the Office of Governor J.B. Pritzker announced that the company would be awarded $6.8 million from the Reimagining Energy and Vehicles in Illinois Act to help fund the development of its new regional research and development facility in the Chicago suburb of Oak Brook.

A very important field of stellarator theory is based on the kinetic equations. This paper reviews the kinetic equations and the reduction of the phase-space dimension by averaging of the fastest time scales. The difference of stellarators to axisymmetric tokamaks is discussed, and the main aspects for stellarator confinement optimization in the neoclassical theory are analyzed. Stellerator-specific applications of the kinetic theory are given in examples.
