Water-based Computers: An Innovative Invention

[ShayanJ]

This is really interesting, so I thought I share it.
These people succeeded in finding a way to build all the logic gates using a system that manipulates water droplets using magnets and a magnetic field. Its slower than current computers but they have other (interesting) applications in mind. But to me, the mere possibility of such a thing and that there are people who actually did it, is really interesting.

Why use water that evaporates when you can use air?

A pneumatic device without solid moving parts can store data as a mode of turbulence. Such devices were being built in the 1960s.
There are pneumatic logic gates. http://hydraulicspneumatics.com/other-technologies/book-2-chapter-2-air-logic-circuits

i read the article and watched the video they had. one question i have is especially after watching the video is where is the control to specify a droplets pathing ?
seemed they followed almost random paths depending on how many options were possible.

I do see you could use the water bridging circuits even if all it did was a circle over a set of predetermined pathways.
