Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The paper describes the electric field in stellarator equilibria and discusses the methods of how to compute the electric potential. The momentum balance in a given magnetic field including viscous and friction forces is considered in the frame of a multifluid model. A general ambipolar condition on closed pressure surfaces is derived that is still valid if magnetic surfaces do not exist. The need for an extended model originates from the singularities of the plasma current in the ideal magnetohydrodynamic model of stellarator equilibria, where parallel current density becomes singular leading to singular parallel electric fields. Viscosity and friction forces eliminate these singularities. The paper investigates the mathematical implications of the extended plasma model and discusses the existence of solutions using the methods of functional analysis.
