I don't have time to do calculations, but maybe the mechanism is as follows (if this video is not a fake): the electrode (or the leads) cause a crown discharge, charges are captured by fog droplets, and then the charged fog droplets move in the electric field. EDIT: See also ...

Also, at lower temperatures the air cannot hold as much water vapor so lower temperatures may not feel as cold as higher temperatures.

Compare to the energy that the Earth surface receives from the sun, how much power comes from the inner melted core ? Very little. The Earth's surface emits about 503 watts per square meter (398.2 W/m2 as infrared radiation, 86.4 W/m2 as latent heat, and 18.4 W/m2 via conduction/convection), or about 260 petawatts over all of the Earth's surface ...

From the Wikipedia article on fog: Sound typically travels fastest and farthest through solids, then liquids, then gases such as our atmosphere. The distance the water molecules are from each other, and temperature, are the reasons sound is affected during a fog condition. Molecule effect: Though fog is essentially water, the molecules are barely ...

According to this link sound (especially high frequency sound) is more attenuated in fog, because it is dispersed by the (billions of) air-water interfaces of all the droplets. This is one reason why a fog horn is a very low sound - low frequencies travel further, especially in fog. For echolocation you want to use high frequencies, and fog is more ...
