Putting datacenters in space for power and cooling benefits may seem like a grand idea, but an online calculator by Andrew McCalip from Varda Space Industries reveals a harsh reality. His calculations show that a SpaceGPT installation would cost over three times more than its earthbound equivalent. The detailed calculator allows for adjusting various parameters to gauge the feasibility of orbital computing. Despite the allure of space-based data centers, McCalip's analysis and Andrew Côté's engineering insights suggest that the challenges and costs may not justify the move at present. AI computing may still be best suited for Earth due to the significant economic and technical hurdles involved.

Six AI data centers proposed for a small town of 7,000, equal to 51 Walmart Supercenters in 17 square mile area — four out of the seven town council members have resigned from their positions as town fights back

Developers have proposed building six AI data centers in Archbald, Pennsylvania, a small town with a population of 7,000. These data centers would cover 14% of the town's 17-square-mile area and are equivalent in size to 51 Walmart Supercenters. The community is pushing back due to concerns about the impact on local utilities, noise, and light pollution. The fight has led to resignations from town council members and delays in the projects, with President Donald Trump getting involved in urging hyperscalers to address community concerns.

New Jersey datacenter expansion got $77m in tax breaks to create exactly one permanent job — JPMorgan's site already scored $35m and currently employs just 25 workers

New Jersey datacenter expansion got $77m in tax breaks to create exactly one permanent job — JPMorgan's site already scored $35m and currently employs just 25 workers

A JPMorgan datacenter expansion in New Jersey received $77 million in tax breaks to create just one permanent job, marking a high subsidy-to-jobs ratio. The expansion, which is part of a $1 billion investment, currently employs only 25 workers despite the substantial tax incentives. The Industrial Development Agency (IDA) believes the deal will benefit the local economy, projecting a $100 million infusion. While the IDA acknowledges the lack of permanent jobs, they argue that the overall economic impact justifies the subsidy. The situation highlights the need for closer scrutiny of datacenter subsidies and their true economic impact.

Silicon Photonics Lights The Way To More Efficient Data Centers

Silicon photonics is paving the way for more efficient data centers by potentially increasing bandwidth density and reducing power consumption, particularly driven by AI workloads. However, challenges such as process compatibility, thermal issues, and mechanical stress arise due to the use of various materials in photonic interconnects. Integrated electro-optical I/O modules are the desired outcome, but design and process complexities need to be addressed. The article delves into the technical aspects of silicon photonics, including the components involved, such as light sources, modulators, waveguides, and photodetectors, as well as the challenges of integrating optical and electronic components for efficient data transmission.

Half of planned US data center builds have been delayed or canceled, growth limited by shortages of power infrastructure and parts from China — the AI build-out flips the breakers

Half of planned US data center builds have been delayed or canceled, growth limited by shortages of power infrastructure and parts from China — the AI build-out flips the breakers

Shortages of power infrastructure components and parts from China have led to delays and cancellations of about half of planned U.S. data center builds. The trade war between the U.S. and China has forced server makers out of China, impacting the availability of electrical equipment crucial for data center construction. Major tech companies like Alphabet, Amazon, Meta, and Microsoft are expected to invest heavily in expanding AI capacity, but constraints in power infrastructure components are hindering progress. The delays in obtaining key electrical components like transformers and switchgear are causing setbacks in deploying AI data centers, with lead times for high-power transformers stretching up to five years. Companies are turning to global markets to address shortages, with Canada, Mexico, and South Korea emerging as major suppliers for high-power transformers.
