A diagram of a dust-powered vacuum cleaner, controlled by a mouse in exchange for cheese & not being trapped.
The dust is swept up by a pair of brooms into a bucket conveyor belt, into a boiler. There it is burned to generate steam to power the vacuum.
In addition to powering the wheels and brooms, the steam also gets used to power a furniture lifter arm with a large hand on the end.
This is an idea that I wish really existed: a dust-powered vacuum cleaner. Alas, it doesn't seem to be practical.
