Impressive to see the complex engineering and manufacturing that goes into something we see so "simply" as a vacuum.
Nuclear power plants (I suppose you could say the same for any other, but this example was given using nuclear power) exist basically so that, a few miles away someone can plug their vacuum cleaner into the wall, hit a switch, and have it work, without having to give it any thought whatsoever. All the complexity of nuclear power, so that you don't have to think about it.
I think this analogy is especially appropriate here, as the design goals of Dyson are similar. Intense engineering so that you have something that does a simple job exceedingly well without additional problem solving required by the user.
