@Tom Scott, A thought, maybe (or maybe you already done similar video), maybe you would find it interesting in doing a video explaining electrical power and the limitations of channeling electricity for very long distances without losing a lot of the energy in the resistance of the cables. Say, for example why we can't set up massive solar energy farms in say the Sahara desert and channel the gained energy through cables all the way to Europe. <br>I got the thought from current issues in Sweden with Northern Sweden producing a lot of energy but have little means of channeling the energy to the southern parts, (It's basically an issue of putting too many nuclear reactors offline/maintenance and the wind/solar not producing enough, forcing since weeks ago now, the start-up of an oil-burning plant, a plant usually only there as a last-resort for harsh winter months), anyway, the part within parenthesis is just to explain why I thought of this whole "electricity, demand and limitations of distance with current technology".
