Commonwealth Fusion Systems Signs PPA with Italian Energy Company Eni

By Zachary Skidmore Google-backed nuclear fusion firm Commonwealth Fusion Systems (CFS) has signed a Power Purchase Agreement (PPA) with Italian energy firm Eni for power from its ARC power plant in Chesterfield County, Virginia. In July, CFS became one of the first fusion firms to sign a PPA with a...

New Entanglement Breakthrough Links Cores of Atoms, Brings Quantum Computers Closer

Quantum entanglement — once dismissed by Albert Einstein as “spooky action at a distance” — has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum practitioners, the reality is rather more mundane: entanglement is a kind of connection between particles that is the quintessential feature...
Once complete, ITER will run fusion experiments using five times as much plasma as the largest reactors in operation today.

5,500 Superconducting Wires Survive Intense Testing for World’s Largest Fusion Reactor

By Gayoung Lee  Stakeholders around the world are vying to realize nuclear fusion—a fossil fuel alternative that promises maximum energy generation with minimal environmental risk. Behind the efforts to build the world’s largest fusion reactor is an equally gigantic global collaboration: ITER, which has just announced a major advance in its quest...

The Future Is Frozen: How Cryogenics Is Redefining Food Innovation

  By Douglas Hoon By Douglas Hoon, CTO and Co-Founder, Cometeer, Inc  Key takeaways: Once relegated to the cold backrooms of industrial storage, cryogenics is now stepping into the spotlight as one of the most promising frontiers in food innovation. Long seen as a basic preservation tool, freezing is being reimagined—not...

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
