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.

Nuclear fusion research promises to harvest the excess energy carried by energetic neutrons when Deuterium and Tritium hydrogen isotopes are fused together to form -particles. Pressure and density conditions needed for these fusion reactions ensure that these charged constituents, together with the free electrons, form a fully ionized plasma at temperatures of about 100 million Kelvin. Any contact with material walls would instantaneously cool the plasma and must be avoided. In the axisymmetric toroidal vessel of a tokamak, a hot plasma is confined primarily by magnetic Lorentz forces. Strong helical magnetic fields that trace out nested toroidal surfaces help to thermally insulate the plasma from the walls and support it against its own pressure gradient. To lowest order, a fluid model of the equilibrium considers only this force balance in the poloidal cross-section of the tokamak, as expressed analytically by the Grad-Shafranov equation.
