It sounds as if they can regulate processing speeds efficiently with such a system:

Stanford assistant professor Manu Prakash has spent almost a decade thinking about such a device, ever since he was a graduate student. The many and varied components required of a fluidic computer have slowly coalesced in his mind over that time, with the most fundamental component of all – an accurate operating clock to drive the logic – being the crucial element in bringing his invention to fruition. Ultimately, Prakash built a rotating magnetic field to synchronize the flow of all the droplets in a precisely timed manner, and act as the clock.

“The reason computers work so precisely is that every operation happens synchronously; it’s what made digital logic so powerful in the first place,” says Prakash. “In this work, we finally demonstrate a synchronous, universal droplet logic and control.”

“We already have digital computers to process information,” says Prakash. “Our goal is not to compete with electronic computers or to operate word processors on this. Our goal is to build a completely new class of computers that can precisely control and manipulate physical matter. Imagine if when you run a set of computations that not only information is processed but physical matter is algorithmically manipulated as well. We have just made this possible at the mesoscale.”

This is revolutionary and we hope you like the video!
