"Tiny Magnets" Imagine you have a cohesive, but ferro-fludic-plug (in the oil and gas industry, its called a PIG I think) But you have a gelataneous, ferro-fluidic plug that is capable of flowing through the complex path of a Tesla Valve - you could direct the plug to flow through the trace magnetically. You could have "passing lanes where the ferro-fluid can exit the valve through another ferro-fluid "door" on the side of the trace - such that you can block, unblock tesla valves with a captured blob of a ferro-fluid that can be stored in the side reservoir. and in a weightless environment, you can use the megnetic ferro-plug to pump fluid continuously this way was the ferrofluid could loop back to an earlier spot through the side channel that only it can enter... If the channels are for micro fluidics, and you have electrical traces along the channels, they could be used to magnetically move things around/open close pathways... and given the current materials that they can print, surely they can print the precise particles needed for the ferrofluid - especially if they are shaped like bucky balls that may be able to be directed to form perfectly packed "walls" where they particle geometry all nests and stacks in a more crystalline pattern? I wonder if this method could allow for micro-fluid-hydraulics, where you can pump the micro hydraulic fluid via ferro-fluids, relying on the tesla valve to allow for forward pressure, and to release pressure, you open a back valve in the same manner.... with a tesla valve in the oposite direction, idealy have them in a helix where one helix is direction a and the other is direction b - and you can have ferrofluid gates at any cross member spine btwn the helix, just as dna... but made out of carbon nanotube bucky ball particles hahah
