IBM has unveiled a prototype of a new brain-inspired computer powered by what it calls "electronic blood".
The firm says it is learning from nature by building computers fuelled and cooled by a liquid, like our minds.
The human brain packs phenomenal computing power into a tiny space and uses only 20 watts of energy - an efficiency IBM is keen to match.
Its new "redox flow" system pumps an electrolyte "blood" through a computer, carrying power in and taking heat out.
Only 1% of a computer is used to process information. And we think we've built a good computer?”
Dr Bruno Michel IBM Zurich
A very basic model was demonstrated this week at the technology giant's Zurich lab by Dr Patrick Ruch and Dr Bruno Michel.
Their vision is that by 2060, a one petaflop computer that would fill half a football field today, will fit on your desktop.
