Vacuum technology is also used in some non-transparent insulation products called vacuum insulated panels. An older-established way to improve insulation performance is to replace air in the space with a lower thermal conductivity gas. Gas convective heat transfer is a function of viscosity and specific heat.

Dielectric breakdown - or how electricity finds the "path

This is a normal operation to switch the load off from the hoover dam. The reason no one looks panicked is because this happens every time they switch off the power from the dam. Because of the immense distance of the overhead line the cables take an incredible about of charge and this is the result of breaking said charge.

Gas-filled tube - Wikipedia

A gas-filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope.Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge.
