Today I want to visit my children again. Since they live at the other end of Vienna, I will not walk or ride the old electric bike. At this longer distance, of course, I fly with my drone, where I have already fully charged the accumulator via the solar chassis of the vehicle. Actually, I want to use my new energy box, but the drone connections do not fit yet. The mobile energy box contains a nuclear fusion reactor and provides me with so much electrical energy to power my home, drone and much more. I like this energy producer, because he is handy small, produces no harmful radiation and he generates clean electricity for years. I can take it anywhere and use it where energy is needed. What we have already learned from the past few years, often the manufacturers of devices do not agree on which worldwide connectors are used. However, it is important that this energy box must be operable and contagious everywhere so that this power generator can be used sensibly.
