computer that operates on water droplet

Hello everyone!
Here i am again with some tech news for you.
The US researchers have achieved a tremendous achievement in the field of technology, they have built a fully functioning computer that runs clockwork-but instead of electrons, it operates by the movement of tiny magnetised water droplets. The ultimate goal is to use the computer to control and manipulate the matter as the same the normal computers manipulate the information.
Although this new water-based computer could do theoritically everything a normal computer can but its process is much slower than the normal computers. But the team is working very hard  and planning things into their mind for their invention.
"We already have digitalis computers to process information. our goal is to build a completely new class of computers that can precisely control and manipulate physical matter," Manu Prakash, lead researcher and bioengineer at Stanford University, said in a press release. "Imagine if when you run a ste of computation that not only process the information but the physicall matter is also manipulated by the machine. We have just made this possible at the mesoscale [ 10 microns to 1 millimetre].
In this work we finnally demostrated a synchronous, universal droplet logic and control," he added
Prakash came up with idea about 10 hears ago. It was easy to work on how to control the water droplets make them move around the maze of an iron bars but finding a way to synchronise these movements proved to be a tough challenge.
In regular computers it is clock that perfectly times every single movement within the system, but Prakash's computer after a very very long struggle find something to do the same with water it was the idea of rotating magnetic field.
