All hail fuel cell - it is advancements like that that will form concepts such as the BakVac possible, but not anytime soon though. Instead of dragging around a vacuum cleaner with the very clear and present dangers of tripping yourself up, why not carry the BakVac vacuum on your back instead? that is definitely the more convenient method of doing things, and at least you know you

won’t be tripping up anytime soon. Unfortunately, such a concept can only be realized once fuel cell technology has caught up in order to be of such practical use. Whatever the case is, the future is definitely an exciting one.
