Disassembled Everhard-Thornley detector from (Philips XL30), showing (from left) the +300V grid and tube, transparent cylindrical light guide, golden clamping nut, and the internal assembly with scintillator disc (+10 kV) on the top. A common photomultiplier would be on the rear side of light guide and is not shown.
To be energy positive, a fusion device must recycle these ions back into the fuel mass so that they have thousands or millions of such chances to fuse, and their energy must be retained as much as possible during this period. The fusor attempts to meet this requirement through the spherical arrangement of its accelerator grid system.
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

3G Bridge is currently actively used in the EDGI and DEGSICO projects as the job bridging technology between service and desktop grids. 3G Bridge enables interconnecting different grid technologies by migrating jobs between them. This way it allows to move specific type of applications to an adequate execution platform, and enables load sharing ...

Illustration of the "reference directions" of the current (), voltage (), and power () variables used in the passive sign convention.If positive current is defined as flowing into the device terminal which is defined to be positive voltage, then positive power (big arrow) given by the equation = represents electric power flowing into the device, and negative power represents power flowing out.
The negative voltage of the accelerator grid prevents electrons of the beam plasma outside the thruster from streaming back to the discharge plasma. This can fail due to insufficient negative potential in the grid, which is a common ending for ion thrusters' operational life.
