HN discussionYes, you are right. And manufacturers are packing more and more wattage in the same space over time. Thanks for mentioning immersion cooling as a potential solution to this; as a shameless plug, we are working very hard to make immersion cooling not exotic anymore at Submer ( https://submer.com ), solving all the problems we saw of the previous state of the art and helping with some of the biggest problems in the da…

HN discussionWe have been following this since Microsoft launched project Natick in 2015[1]. Comupting has a large effect on our planet, data centers consume over 6% of the world's electricity (more than India) and generate over 4% of the world's CO2 emmissions (twice that of commercial air-travel)[2]. The approach taken by Microsoft is a nice PR-stunt but we think it's impractical/difficult to carry out maintenance and leads to…

HN discussionI'd love to discuss your research. We've been working low-profile during the last years doing a lot of R&D and experimenting with different fluids and components. Mineral oil is ok for experimentation, but for long term material compatibility and fire risk I wouldn't recommend it. FWIW I co-founded https://submer.com where we've developed an all-embedded computing immersion cooling solution that is virtually compati…

Coincidentially at Submer we help data centers (rack servers, cloud, HPC, colos, miners, supercomputers…) become more sustainable, efficient and scalable thanks to our sustainable active immersion cooling technology. Apart from the ‘Submerge’ meaning, Submer is also the acronym of our company values, the first being ‘Sustainable’. We are also backed by impact investors like Norrsken VC and PlanetFirst. If inter…

on “Ask HN: What are ethical companies like Patagonia and some digital counterparts?”They are using Submer's SmartCoolant: https://submer.com/smart-coolant-liquid/ . In short, this appears to be a test of an existing commercially-available product.

on “Lighting a Fire Under Liquid Immersion Cooling”Yes! A very long and tough journey but extremely exciting times... In 2015 we founded Submer ( https://submer.com ) with my brother-in-law (I know... we knew each other very well and for more than a decade) to try to solve the biggest problems in the data center industry with a highly-efficient liquid immersion cooling technology. These problems are now in an inflection point where all are converging. Among others:…

on “Ask HN: Any Hardware Startups Here?”Hi HN! Datacenters and cloud providers consume 6% of the global electricity (more than India) and generate 4% of the global CO2 emissions (more than 2 times commercial air travel). After 2 years of hard work, we've been able to finally introduce the first Open Compute and hyper-scale compatible Computing Liquid Immersion Cooling solution this morning in the Open Compute Global Summit in San Jose, CA. With this techn…
