URFC Unitized Regenerative Fuel Cell
A Unitized Regenerative Fuel Cell (URFC) is a regenerative fuel cell (RFC) with both processes done in the same fuel stack. It is a Proton-Exchange Membrane Fuel Cell (PEM) style using usually hydrogen and oxygen. Reasons for development of this compact unitized RFC is less weight and mass.
A URFC combines an electrolyzer that separates the water molecules to make and store hydrogen and oxygen and reverse the process to combine the two elements and make electricity and H2O (water).
Nuclear Fusion Laser Machine
In nuclear physics and nuclear chemistry, nuclear fusion is the process by which multiple like-charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy, which allows matter to enter a plasma state.
Nuclear fusion occurs naturally in stars. Artificial fusion in human enterprises has also been achieved, although has not yet been completely controlled.
