Sustainable computer chips set to supercharge AI

By Zarkon Group,

Spotted: It is clear that AI represents the future of computing, but today’s most popular AI chips (GPUs) are expensive and require huge amounts of energy, which is incompatible with both broader use outside data centres, and a low-carbon future. Now, EnCharge AI, which was spun out of the lab of Dr Naveen Verma at Princeton University, is building on new research outside of the GPU model to accelerate AI capabilities for a broader range of users.

To create chips that can handle modern AI in smaller and/or lower-energy environments, the researchers turned to analogue computing. The team designed capacitors to work with the analogue signal to switch on and off with extreme precision. By having this computation done directly in memory cells (in-memory computing), they created a chip that can run powerful AI systems using much less energy.

EnCharge’s PR Account Manager, Yhea Abdulla, explained to Springwise that, “It’s all geometry-based, aligning wires that come in a capacitor (no extra parts, costs, or special processing). They combined this with their research in in-memory computing (IMC) to enhance computing efficiency and data movement issues, bringing in the value of analogue without the historical limitations.”

EnCharge has recently been awarded an $18.6 million (around €17.2 million) grant by the US’s Defense Advanced Research Projects Agency (DARPA). The funding will be used to further develop the chip technology as part of DARPA’s Optimum Processing Technology Inside Memory Arrays (OPTIMA) programme to unlock new possibilities for commercial and defense-relevant AI workloads not achievable with current technology.

From climate forecasting to food waste and cancer detection, AI has already grown to the point where it is becoming incorporated into many aspects of daily life. This makes it vital that we reduce the energy needed to run AI applications.

Could ceramic chips reduce emissions from high-heat industry?

Could ceramic chips reduce emissions from high-heat industry?

By Zarkon Group,

Spotted: Although we are seeing some progress towards climate goals in certain areas of the economy – such as mobility and electricity generation – industries that require very high process temperatures remain difficult to decarbonise, and are overwhelmingly dependent on fossil fuels like natural gas.

Now, Estonian cleantech startup Efenco has come up with a creative solution to reduce emissions from industries that require temperatures above 300 degrees Celsius. This novel technology can be applied to natural-gas-powered processes in the short term, but will also improve the efficiency of combustion processes run on hydrogen – a clean fuel that is tipped to play an important role in industry as the world moves away from fossil fuels.

The company, whose name is a shortened version of efficient energy conversion, has created High Energy Ray Ceramic (HERC) technology that makes high-temperature combustion of gassy fuels more efficient. Using a patented cold plasma technique, the company’s ceramic chip recycles heat from typical industrial heating systems to produce higher temperatures with fewer emissions. 

Plasma is a high-energy state that enhances chemical reactions. In the case of commercial heating for steel, pulp, and paper manufacturing – as well as district heating and cement production – the HERC technology has the potential to eventually improve the combustion efficiency of natural gas by 40 per cent and hydrogen by up to 75 per cent. So far, however, the HERC prototype has demonstrated an 18 per cent combustion efficiency gain.

No external source of energy is required to make the HERC chips work, and they can be easily installed into existing gas boilers. No additional machinery or expertise is needed.  

Overall, use of the HERC chips can make significant reductions both in terms of fuel costs and carbon emissions. Efenco currently has six partnerships in place and is working towards the elimination of 77 million tonnes of carbon emissions by 2030 through the installation and use of its technology. Having recently raised €4.5 million in funding, the company plans to continue advancing the development of the chips and begin designing a version for domestic and small-scale use.  

Improving efficiency and usefulness while reducing environmental harm is the focus of many technologies, with Springwise’s database including examples of a high-performance magnet that does not use any rare earth elements and a nano aerogel that cuts refrigeration emissions.
