Addressing Liquid Cooling Gaps in AI Data Centers

Curated by Shubham · TechCapsules · Jun 23, 2026

AI-summarised brief · reviewed before publication

xMEMS engineers Tom Tarter and Henry Neynavaee highlight the limitations of liquid cooling in AI data centers. Liquid cooling effectively manages heat from high-power processors but leaves secondary components exposed, leading to temperature-related issues and throttling. To address this, the engineers propose localized, solid-state micro-cooling that targets specific hotspots with minimal power consumption. This approach aims to maintain thermal balance across the entire server, rather than just cooling the highest-power chips.

💡 Why It Matters

· Closing thermal gaps in AI data centers can significantly reduce operating expenses, particularly for hyperscale operators.
· By minimizing the need for high-power fans, data centers can lower their energy consumption and extend the lifespan of critical components.

Tesla just trademarked MEGAPOD: here’s what it is

Tesla has trademarked 'MEGAPOD' with the USPTO, listing it as modular data center hardware systems for artificial intelligence computing. The application describes MEGAPOD as self-contained units integrating servers, AI processing hardware, networking components, power distribution, and cooling systems. This filing aligns with Tesla's AI compute strategy, which includes deploying AI agents on parked vehicles and dedicated compute units at Supercharger stations. The modular hardware platform could support scalable, rapid deployment of distributed compute resources, complementing Tesla's other AI infrastructure efforts.

💡 The MEGAPOD trademark application suggests Tesla is preparing to launch a modular AI computing platform, potentially enabling edge or regional AI inference without relying on centralized data centers. This move could accelerate Tesla's AI ambitions, particularly in the context of its Digital Optimus project, which aims to develop AI agents capable of handling complex digital tasks.

SpaceX confirms third massive compute deal at Colossus data center

SpaceX has confirmed its third massive compute deal at the Colossus data center in Southaven, Mississippi. The deal, worth approximately $6.3 billion, grants Reflection AI immediate access to NVIDIA GB300 chips at SpaceX's Colossus 2 data center. In return, Reflection will pay SpaceX $150 million per month, starting July 1, with either party able to terminate the agreement after 90 days' notice. This deal highlights SpaceX's strategy of commercializing its Colossus supercomputing infrastructure, originally developed for Elon Musk's Grok AI models.

💡 The Reflection contract underscores SpaceX's growing influence in the AI infrastructure market, where demand for advanced training and inference capacity is surging amid chip shortages. By transforming its data centers into flexible revenue sources, SpaceX is diversifying its income streams beyond traditional rocket launches and Starlink operations, positioning itself as a leader in the lucrative AI sector.

FERC Mandates Fast-Track Data Center Grid Access, Shielding Ratepayers from Costs

Federal regulators have issued orders to six major US grid operators to eliminate bottlenecks preventing AI data centers from connecting to the power grid, with developers bearing the connection costs. The orders, approved by the Federal Energy Regulatory Commission, cover grid operators serving 200 million Americans and aim to integrate large energy loads into the bulk electric grid while protecting consumers. The rules require grid operators to submit reliability reports and reform pricing structures within 60 days. This move addresses AI power demand as a national infrastructure crisis requiring federal coordination, shielding ratepayers from costs.

💡 By shielding ratepayers from AI infrastructure costs, FERC's orders protect household electricity customers from shouldering the financial burden of data center connections. FERC's move sets a standard for responsibly integrating large energy loads into the grid.

Bill Gates to Google, Microsoft, Amazon, Meta & every company building data…

Bill Gates has expressed concerns that some data centers being built by companies like Google, Microsoft, Amazon, and Meta may not be profitable due to high electricity costs. He stated that the next generation of chips will arrive before the current ones have paid for themselves, and that no community will absorb higher power bills for a hyperscaler's bet that may not pay off. Gates' comments are significant as his own company, TerraPower, stands to profit from the buildout, but he is warning that some data centers will lose their investment and leave hosting towns with significant infrastructure costs. The White House has pledged to cover the cost of new power generation, but backlash against data centers continues, with 70% of Americans opposing a data center near their home. Gates' warning highlights the potential risks of the current data center buildout frenzy. His comments emphasize the need for companies to consider the long-term costs and benefits of their investments.

💡 Gates' warning underscores the potential for data centers to become stranded assets, leaving towns with significant infrastructure costs and no economic benefits. His comments also highlight the disconnect between the industry's growth plans and the concerns of local communities.

Meta offers paid training for AI data center jobs

Meta is investing $115 million in its America's Workforce Academy to train workers for skilled trade jobs tied to AI data center construction. The program is open to qualified veterans, recent graduates, and career changers, and will cover tuition, airfare, lodging, and a daily stipend during training. Participants will be trained for jobs such as fiber technicians, electricians, and welders, with a job offer guaranteed upon graduation. The program will be piloted in Ohio, Indiana, and Texas, with the goal of creating a faster path into trade careers without college debt. Meta's investment aims to address the need for trained workers in AI infrastructure construction.

💡 By offering a debt-free path to skilled trade jobs, Meta's program addresses a critical labor shortage in AI data center construction, potentially easing the buildout of AI infrastructure. It also gives Meta a stronger jobs message amid growing community scrutiny of data centers.

Abu Dhabi’s MGX weighs multi-billion deal for Singapore-based data centre operator DayOne:…

Abu Dhabi's MGX is considering a multi-billion dollar deal to acquire Singapore-based data centre operator DayOne, marking a significant step in its global expansion into technology. DayOne operates and develops data centres across South-east Asia, Hong Kong, Japan, and Finland, and has been planning a US initial public offering targeting a valuation of $20 billion. MGX has been working with an investment bank to prepare for the potential transaction, but a deal may not proceed and DayOne may still opt for an IPO. The acquisition would be MGX's first in Asia, as it pursues international expansion with over $100 billion in assets.

💡 MGX's potential acquisition of DayOne underscores the UAE's aggressive push into the AI sector as part of its economic diversification efforts. It would also cement MGX's position as a major player in the global technology industry, with investments in some of the largest AI companies worldwide.
