Google and Commonwealth Fusion Systems Sign Strategic Partnership

Credit: Commonwealth Fusion Systems Google and Commonwealth Fusion Systems (CFS) today announced a new global milestone, a bold partnership to develop, deploy and scale clean, secure fusion power. Google signed a power purchase agreement (PPA) for 200 megawatts (MW) of electricity from CFS’ inaugural ARC power plant, which CFS expects...

Korean Cable Corp Signs Deal Next-Gen Superconductors

Image source: Taihan/SuperNodeA leading Korean cable company has signed a deal with an Irish firm to develop “next-generation” superconducting cables for the offshore wind industry. Taihan will work with Dublin-based SuperNode on the design and roll out of polymer-based transmission cables which promise to “significantly” enhance efficiency and simplify installation...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Seeking technical publication that explains the science behind the cryogenic treatment of aluminum

Would you know of a technical publication that would list the benefits and explain the science behind the cryogenic treatment of aluminum, specifically a 356-T6 aluminum cylinder head casting? Eddie Phillips

Source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K

Can anyone recommend a source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K? Also, I would be interested in finding a facility that can measure this information. Any information will be greatly appreciated. William Einziger, GE Healthcare

Looking to purchase new LN2 freezer: any suggestions?

I will be purchasing a new liquid nitrogen freezer soon, but I am limited by space restrictions. The freezer cannot be more than 38 inches wide. However, it would be beneficial if the freezer holds a high number of racks such as 24. In addition, we prefer not to purchase...

Affordable flow meter to measure LN2 flow through a pipeline

I am trying to find out if anyone knows of or has used an affordable flow meter that can measure liquid nitrogen flow through a pipeline. It doesn’t need to be very accurate as it’s really to allow people in different departments to allocate cost rather than for scientific measurement....
