As we approach the extent to which powerful processors can be miniaturized the engineering has to move in a new direction.
At IBM that direction is a brain-inspired 3D architecture, staking processors and memory in close proximity. But it is a solution with the same old problem. How do you remove all the heat?
One possible answer; Electronic Blood.
The art of liquid cooling has been demonstrated by Aquasar and put to work inside the German supercomputer SuperMUC which – perversely – harnesses warm water to cool its circuits.
SuperMUC consumes 40% less electricity as a result.
But for IBM to truly match the marvels of the brain, there is a third evolutionary step it must achieve – simultaneous liquid fueling and cooling.
Just as blood gives sugar in one hand and takes heat with another, IBM is looking for a fluid that can multitask.
Vanadium is the best performer in their current laboratory test system – a type of redox flow unit – similar to a simple battery.
First a liquid – the electrolyte – is charged via electrodes, then pumped into the computer, where it discharges energy to the chip.
Redox flow is far from a new technology, and neither is it especially complex.
But IBM is the first to stake its chips on this “electronic blood” as the food of future computers – and will attempt to optimize it over the coming decades to achieve zettascale computing.
Many great achievements in engineering have looked to nature for as a path to success. IBM is exploring the compact efficiency of the human brain as a model for getting more out of a more compressed package.
“Ninety-nine per cent of a computer’s volume is devoted to cooling and powering. Only 1% is used to process information. And we think we’ve built a good computer?”
“The brain uses 40% of its volume for functional performance – and only 10% for energy and cooling.”
Michel’s vision is for a new “bionic” computing architecture, inspired by one of the laws of nature – allometric scaling – where an animal’s metabolic power increases with its body size.
Can they built it better, faster, even stronger…? Will it cost 6 million dollars? Can they get that power into a form factor anyone can use at a price they can afford. It’s not as if they have not done it before.
We’ll just have to wait and see.

Computer aided or assisted design has evolved thanks to the robotic revolution and innovations that made 3D printing a reality. Today’s designers and craftsman can exchange the hand-tools they used to use for digital design tools and equipment that allows them to turn their imagination into a part or product in a fraction of the time. And not just where they are, but anywhere in the world where the equipment and materials are at hand, without ever having to leave their workshop.
