China has yet to respond—but Beijing has multiple options in their arsenal. Nvidia’s A100 , for comparison, is capable of over 600 teraflops and matches the 600 Gbps interconnect speed. Nvidia has already responded by introducing a China-specific chip, the A800, which appears to be a modified A100 cut down to meet the requirements.

New Design for an Artificial Leaf for More Efficient Hydrogen Production

Green Car Congress

Researchers at the State Key Lab of Matrix Composites at Shanghai Jiaotong University, Shanghai, China have described a new design strategy to produce an “Artificial Inorganic Leaf” (AIL), which could lead to working prototypes that capture solar energy and use it efficiently to change water into hydrogen fuel.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. In comparison, increasing the H/C eff ratio of pyrolysis oil from 0 to 1.4

The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. Vard Group is part of NuProShip , a consortium of the Norwegian maritime authority, universities, shipbuilders, and shipping companies that aims to develop a Generation IV reactor for marine vessels. We needed to get the conversation started.”

Tsinghua Researchers Find that Sugarcane Juice is a Good Fermentation Feedstock for Algal Biodiesel

Green Car Congress

Researchers at Tsinghua University in China have shown that sugarcane juice is a good feedstock for biodiesel production, when used to support the growth of the alga Chlorella protothecoides by heterotrophic fermentation. Conversion ratios of sugar/biomass and sugar/oil using SCH were 15.2 There are bottlenecks in this pathway.

Finding The Wisest Ways To Global AI Regulation

And that includes academia, which historically has had a very vibrant role in this field, but since 2014, what we’ve seen is this slow decline of academia in the space in comparison to where industry’s really taking off. I’ve been troubled by that too, especially the sort of vitriol that seems to come out in some of these conversations.
