UK mini data center start-up hails energy savings from heat reuse at entertainment center



British startup Deep Green has set its sights on accelerating the rollout of heat reuse schemes in data centers across the country after deploying its first heat recovery unit at an entertainment center in Exmouth, Devon.

The company specializes in providing mini data centers dubbed “digital boilers,” which consist of servers whose waste heat is converted into hot water that can be used by local businesses.

Exmouth Leisure Center is now home to the first deployment of a digital boiler and the company claims the installation will reduce gas requirements by 62%, cut carbon emissions by 25.8 tons and save owners more than £20,000 a year in energy costs.

The Exmouth installation consists of 12 servers running power-hungry AI, machine learning and video rendering workloads, and their heat is captured using immersion cooling technology and transferred free of charge to the existing hot water system.

The company said the cost savings could be an attractive factor for other entertainment center operators, given that many have faced a 150% increase in energy costs since 2019, with about 79% of them facing closure as a result.

The company said it plans to continue to roll out Exmouth with similar projects in Bristol and Manchester in the coming weeks.

This technology can also be used by other types of businesses that have constant heat needs, such as bakeries, distilleries and apartment buildings. “In addition to swimming pools, this technology can provide 30% of industrial and commercial heating needs,” the company said in a statement.

Mark Bjornsgaard, Deep Green’s CEO said that as many businesses struggle with rising energy costs, its technology could make a huge difference to society.

“The current data center infrastructure is inefficient, consumes huge amounts of energy and generates huge amounts of waste heat,” he said. “However, at the same time, there are many businesses that need heat and face rising electricity bills.

“By moving data centers from industrial warehouses to human centers, our ‘digital boilers’ put waste heat to good use, saving local businesses thousands of pounds on energy bills and reducing their carbon footprint.

“Organizations that are serious about supporting society and reducing carbon footprint should not forget the huge impact of their computing needs,” said Bjornsgaard. “Now Deep Green provides the answer.”

Jane Nickerson, Swim England’s CEO said it’s encouraging to see places like Exmouth innovate to get through the energy pricing crisis.

“At a time when so many pools are struggling with skyrocketing energy bills, it’s great to see pools using such innovative solutions that can help facilities operate more sustainably, both environmentally and economically,” she added. .

Transport problems

The idea of ​​reusing data center waste heat is not new, but the idea has struggled to gain momentum in the past because the amount of warm air generated by these facilities is extremely difficult to transport over long distances.

The approach that Deep Green takes, where data centers are co-located with recipients of this heat, is one way to address this problem, and an idea that others have adopted as well.

For example, Computer Weekly previously reported on some data centers in the Scandinavian countries whose waste heat is pumped directly to nearby fish and lobster farms, so the creatures need the ambient temperature they need at all times.

For now, colocation giant Equinix recently embarked on a similar ramp-up at one of its data centers in Paris, whereby its waste heat is being used to power an urban rooftop farm.

Considered the first of its kind in France, this project, curated by Reid Brewin Architects (RBA), consists of a 430-square-meter climate-controlled greenhouse used to grow seasonal fruits and vegetables. above the data center.

“It is increasingly important that we step up our actions and mitigate the environmental impact of an increasingly digital world,” said John Hutchinson, director of the RBA. “Sustainability and environmental protection are at the heart of everything we do, and this opportunity has already inspired our customers to take further initiatives.”

Baidu shares are recovering from a sharp fall after the demonstration of the ERNIE chatbot, a ChatGPT-style service.



Hong Kong

Shares in Chinese search giant Baidu surged the day after it opened. ERNI Botit’s a response to the ChatGPT craze.

Its shares rose 14.3% on Friday in Hong Kong, making it the biggest winner in the Hang Seng index.

. They also rose 3.8% in New York during US trading on Thursday.

The day before Baidu

was the biggest loser of the same index. Its shares in Hong Kong fell 6.4% after a public demonstration of its bot failed to impress investors. Since February, more than 650 companies have joined the ERNIE ecosystem, CEO Robin Li said during the presentation.

The cancellation comes after the company said more than 30,000 businesses signed up to test its chatbot service within two hours of its demo.

“The high degree of interest from enterprises is positive, and we expect Baidu to continue to meet the demand of Chinese enterprises for generative AI,” Esme Pau, Macquarie’s head of Chinese and Hong Kong Internet and digital assets, told CNN.

She said the company’s stock rebounded on Friday as some users, including analysts, shared positive feedback about their own experiences with ERNIE, suggesting the bot has more advanced capabilities.

During the presentation, Baidu showed how its chatbot can generate a company newsletter, come up with a corporate slogan, and solve a math puzzle.

But its shares fell on Thursday because the demo was “pre-recorded and not live, leaving investors skeptical about the reliability of the ERNIE bot,” according to Pau.

The Baidu demo also came just days after the launch of GPT-4, which “raised the bar for ERNIE,” she added.

GPT-4 is the latest version of the AI ​​technology used in ChatGPT. The service wowed users this week with its ability to simplify coding, quickly create a website from a simple sketch, and pass exams with high marks.

Pau noted that Baidu’s shares were already “slightly down” ahead of Thursday’s software showcase, highlighting pressure from investors who raised expectations after the GPT-4 launch.

“ERNI also doesn’t have [same] multilingual capability like GPT-4 and not yet improved for English queries,” she said. “In addition, the ERNIE launch did not provide sufficient quantitative indicators compared to the GPT-4 launch earlier this week.”

Like ChatGPT, ERNIE based a language model that is trained on vast amounts of data on the Internet to generate compelling responses to user queries.

Li said Baidu’s expectations for ERNIE were “close to ChatGPT or even GPT-4.”

But he acknowledged that the software “isn’t perfect yet,” adding that it was first launched for corporate users. The service is not yet available to the general public.

Baidu announced its chatbot last month. Some critics say the service will add fuel to the ongoing rivalry between the US and China over new technologies.

Li tried to shake off that comparison at the time of launch, stating that the bot “is not a tool of confrontation between China and the United States in science and technology, but is the product of generations of Baidu technicians pursuing the dream of changing the world through technology.” “.

“This is a completely new platform for us to serve hundreds of millions of users and empower thousands of industries,” he said.

Baidu says its service stands out for its advanced understanding of Chinese queries, as well as its ability to generate different types of responses.

“ERNIE Bot can create text, images, audio and video from a text prompt, and is even capable of voice transmission in several local dialects such as Sichuanese,” the company said in a statement.

By comparison, GPT-4 can also parse photos, but currently only generates text responses. in accordance with its developer, OpenAI.

Baidu is not the only Chinese firm working on such technology. Last month, Alibaba

announced plans to launch its own ChatGPT-style tool, adding to the roster of tech giants to join the popular chatbot.

For now, Baidu has a first-mover advantage in China, according to analysts.

“We believe ERNIE is three to six months ahead of its potential competitors,” Pau said.

On Friday, Baidu also announced a milestone in its transportation business, saying it is the first operator in Beijing to be allowed to provide driverless car hailing services in the city.

Companies are not allowed to charge passengers in the capital for a new service yet. Previously, the driver was required to be in the front passenger seat to take control in the event of emergencies.

Baidu provides commercial driverless taxi services in the cities of Chongqing and Wuhan.
