The silicon semiconductor industry has chugged along for more than 50 years. Like a steamroller, it has trundled over bumps and holes, while defying repeated warnings that it was running out of fuel or was about to be overtaken by flashier competitors.

So we technologists are understandably reluctant to speculate about the end of silicon. And yet, speculate we must. After decades of steady improvements to the efficiency and speed of our computer chips, brought about by physically shrinking the dimensions of silicon transistors, we’ve reached a point where the massive effort to miniaturize those switches ekes out only very modest gains in performance. The steamroller still rolls, but it’s slowing down, and the maintenance and upkeep on it are fast becoming unsustainable.

AI Could Make Air Conditioners 10x Better

Hyperganic is using AI to design new heat exchangers that can be 3D printed in metal

White steam curls out of an object composed of black pipes that twist helically. A cutaway shows a convoluted inner structure.

Hyperganic partnered with TRUMPF to algorithmically design this heat exchanger based on physical principles found in nature. They are now partnering with Krailling and Strata Manufacturing to build a more efficient residential air-conditioning system with 3D printed heat exchanger

The energy we spend on cooling indoor spaces has tripled since 1990, and it’s going to triple again by 2050 as developing and middle-income countries embrace air-conditioning. Researchers are putting a lot of sweat into innovative cooling technologies that consume less energy, but none seem ready for prime time in the near future.

“Air-conditioning innovation is like nuclear fusion, always twenty years in the future,” says Lin Kayser, CEO of Hyperganic, an AI-based design software firm based in Munich.

Electric vehicles are gaining in popularity around the world, especially with the high cost of fuel. But some of the current EV models aren’t a good fit for owners who can’t wait around for hours for their batteries to charge, such as taxi drivers, delivery people, and ride-hailing services.

One startup trying to solve this problem is ARC Ride, in Nairobi, Kenya.

Accelerate Time to Market with Calibre nmLVS Recon Technology: A New Paradigm for Circuit Verification

One thing is clear…tapeouts are getting harder, and taking longer. As part of a growing suite of innovative early-stage design verification technologies, the Calibre nmLVS Recon tool enables design teams to rapidly examine dirty and immature designs to find and fix high-impact circuit errors earlier and faster, leading to an overall reduction in tapeout schedules and time to market.
