accumulated over the past four decades. With tight supplies have come higher prices, and some major helium users are turning to conservation methods to keep their budgets from soaring and their gas supply from drifting up, up
To fuse Hydrogen in his device, [Carl] first evacuates a vacuum chamber. Deuterium (Hydrogen with an added neutron) is injected into the chamber, and aspherical cathodemade of Tungsten is charged to 75 kV. The deuterium gas is heated and confined by the cathode and fuses into Helium. The...
A star expands to become a red giant when it has fused all the hydrogen in its core into helium. If the star is in a binary system, its envelope can overflow onto its companion or be ejected into space, leaving a hot core and potentially forming a subdwa
