Tackling the #energy demands of #supercomputers through technology and experience: Satoshi Matsuoka, Director of the @riken Center for Computational Science, and Dieter Kranzlmüller, head of LRZ, signed a Memorandum of Understanding to establish close cooperation in the field of #energyefficiency Both #supercomputing centers rely on water-based cooling and aim to advance technology for thermal optimization as well as for the recovery and reuse of #wasteheat: https://www.lrz.de/en/news/detail/riken-r-ccs-and-lrz-collaborate

We certainly will need to preserve the #tech and #knowledge to build these and consider using #WasteHeat that way more often than not, because it is #simple, #efficient, has no moving parts and thus not failure points.

  • It certainly would make it easier and simpler to build a lot of #passive #sensors and also enable more #FrugalComputing just by virtue of being a non-moving, no-maintenance deal.

In case anyone gets reminded by this design: Yes, the Russians did abuse the same principle for RTGs like the infamous Beta-M...

We are introducing a #CO2neutral heating system on the Garching research campus, using #wasteheat from the #supercomputer and #geothermal sources. This is expected to reduce emissions by around 30,000 tons per year: http://go.tum.de/752215

TUM will save 30,000 tons of CO2 per year in the future

The TUM Research Campus Garching will be supplied with CO2-neutral heat in the future – saving 30,000 tons of CO2 per year.

Findland's underground data centers now heat entire city blocks using only server waste heat. The heat is captured and redirected into district heating networks, warming homes, businesses, schools, and even saunas.

This is next-level circular economy: turning digital infrastructure's biggest problem (cooling) into a city-wide heating solution. Zero waste, maximum efficiency.

All essential for energy efficiency which will reduce the cost of the renewable energy networks, and reduce cost to the end-user

I continue to believe that #WasteHeat is probably a much bigger factor in global #ClimateCollapse than most people are willing to consider. It's not just #greenhouse gas #emissions. All the fuel we burn, all the power we generate, all produces not insignificant thermodynamic losses. 2/3rds of electrical power generation is lost as waste heat, before it reaches the end user, and a large proportion of what is actually consumed is also lost as waste heat. Then there's direct combustion of fuels.

This NYC high-rise is using heat pumps and waste heat to cut fossil fuels

The cutting-edge, state-backed project at 345 Hudson could be a model for other big buildings sprinting to comply with the city’s building decarbonization law.

Instead of wasting heat we could be putting it to use. We could do this for buildings across Canada #energyefficiency #wasteheat #SustainableLiving

These Ottawa-area buildings are heated with industrial waste, as reuse technology gains steam | CBC News

Residents of a new development in Ottawa-Gatineau are using industrial waste to keep their homes warm: specifically, waste heat from a local paper plant. Heat is being thrown away all around us — but it can be captured to heat buildings in a more efficient and climate friendly way.

We need more of this - but there seem to be all sorts of legal - not technical - restrictions that limit this clever use of #WasteHeat from summer aircinditioning. It's important because #HeatPump efficiency depends on the temperature of the source of extracted heat. ANd peak demand for heat energy occurs just when air source heat pump efficiencies are lowest. ANd the size of the electrical grid depends on peak demand - the higher the peak demand, the greater the capital investment.

So why aren't we looking at how to enable community/district systems that do the same thing?

To Slash Carbon Emissions, Colleges Are Digging Really Deep

A growing number of colleges and universities are using deep underground pipes to heat and cool their buildings without burning fossil fuels.

There are technologies that can harvest energy and store waste heat for later use. This heat can be captured, stored, and distributed to heat homes and businesses, reducing greenhouse gas emissions. Technology is already available to do this, and it would significantly impact our ability to achieve net-zero heating systems. Reusing waste heat is a win-win for the environment and the economy. #WasteHeat #NetZeroHeating #SustainableEnergy https://www.weforum.org/agenda/2023/08/reuse-waste-energy-net-zero-heating-systems/
How to reuse waste energy for net-zero heating systems?

Reusing waste heat energy can help us reduce our reliance on fossil fuels, improve air quality and help us achieve net-zero emissions.
