Iíve seen drink fountains for dogs that kind of look similar, where they pump water from a reservoir from below up to bowl on the top. Keeps the water moving and not stagnate / stale etc. and the water lasts for a week rather than a day Ė They look similar and perhaps are but they use a standard pond water pump with flexible tubing, not using an impeller like Teslaís design does.

I believe (at least the oneís Iíve seen) chocolate fountains use an Archimedes like screw to lift the viscous chocolate / olive oil mixture to the top.
