What If #OmniPath Morphs Into The Best #UltraEthernet?
Many #HPC centers in #US – importantly #Sandia and #LawrenceLivermore as well as the Texas Advanced Computing Center (#TACC) – wanted an alternative to #InfiniBand or proprietary interconnects like #HPE/#Cray’s Slingshot, and they have been funding the redevelopment of Omni-Path. And now, #CornelisNetworks is going to be intersecting its roadmap with Omni-Path switches and adapters with the #UEC roadmap.

Sites with #radioactive material more vulnerable as #ClimateChange increases #wildfire, #flood risks

Climate change increasingly threatens research laboratories, weapons sites and power plants across the nation that handle or are contaminated with #radioactive material or perform critical energy and defense research.

"The Nuclear Regulatory Commission [#NRC] considers only historical #ClimateData rather than future projections in licensing decisions and oversight of #NuclearPowerPlants, according to a General Accounting Office study in April that recommended the NRC 'fully consider potential #ClimateChange effects.' The GAO found that 60 of 75 U.S. plants were in areas with high flood hazard and 16 were in areas with high wildfire potential."

Sites with radioactive material more vulnerable as climate change increases wildfire, flood risks

Climate climate change increasingly threatens research laboratories, weapons sites and power plants across the nation that handle or are contaminated with radioactive material or perform critical energy and defense research. The Department of Energy recently required existing sites to assess vulnerability to fires, floods and other disasters. Now the agency division that oversees active sites will decide how to consider future climate risks when issuing permits or licenses. The General Accounting Office is urging the Nuclear Regulatory Commission to do the same for nuclear power plants.

Cautiously optimistic about all the scientific breakthroughs that feel like.. MAYBE they could be in the realm of possibility after all? 🤞😖🤞

U.S. lab says it repeated fusion energy feat — with higher yield

The achievement is another key step — albeit in a journey that may take decades to complete — in the quest for an unlimited source of cheap and clean power.

How They Did It: Fusion Ignition with NIF Laser Scientist

How did we achieve nuclear fusion? Neil deGrasse Tyson and comedian Chuck Nice learn about human-made thermonuclear fusion, the world’s most powerful lasers, and harnessing nuclear power with operations manager of The National Ignition Facility at Lawrence Livermore National Labs, Bruno Van Wonterghem. Can we make fusion happen with less than 300 million jules? Find out about the NIF and the work being done in nuclear energy. We discuss quantum tunneling in the sun and the energy needed to overcome repulsive forces. Is our fusion hotter than the sun? What are deuterium and tritium? Discover helium 3 and heavy hydrogen. What is the difference between a powerpoint laser and the world’s most powerful fusion lasers? Learn about the physics of lasers and what wavelength of laser is best for nuclear fusion. Can we make our most advanced lasers better? We explain what plasma is and whether fusion will be scalable. Will we one day have nuclear fusion power stations or portable fusion reactors attached to our cars? What is in store for the future of Lawrence Livermore National Labs? How can fusion be improved? Thanks to our Patrons Gavin Mallow, Willest74, Isaac Labbe, Allen, and Beefcake for supporting us this week. NOTE: StarTalk+ Patrons can watch or listen to this entire episode commercial-free.

* 1.25 MJ of #fusion energy produced

but
300 MJ were needed to produce the laser beam in the first place

This seems to be the summary of the #LLNL #LawrenceLivermore #breakthrough -

"“You’ll need gains of 30 to 100 in order to get more energy for an energy power plant,” Dr. Herrmann, program director for weapons physics and design at the Livermore, said."
