Thermoelectric Heating Comes In From the Cold

Before architect César Martín-Gómez could send his latest thermoelectric experiment to Antarctica in 2018, he had to make sure that soldiers from the Spanish Army could get it right on the first try. In the laboratory, he could always run the experiment—a scale model of a solid-state thermoelectric heater—a second time if...

ExxonMobil to Build CCS Pilot Plant with FuelCell Energy Using Carbonate Fuel Cell Technology

ExxonMobil’s affiliate Esso Nederland BV plans to build a pilot plant at its Rotterdam manufacturing complex to test a breakthrough technology that could significantly reduce CO2 emissions from key industries. The pilot plant aims to obtain data on performance and operability of the carbonate fuel cell (CFC) technology, jointly developed with...

Artificial Intelligence and NASA’s First Robotic Lunar Rover

When NASA’s VIPER (short for Volatiles Investigating Polar Exploration Rover) lands on the surface of the Moon on a mission to better understand the environment where NASA plans to send astronauts as part of the increasingly complex Artemis missions, its journey will be guided by the ingenuity of its human...

DARPA-Funded Research Leads to Quantum Computing Breakthrough

A team of researchers working on DARPA’s Optimization with Noisy Intermediate-Scale Quantum devices (ONISQ) program has created the first-ever quantum circuit with logical quantum bits (qubits), a key discovery that could accelerate fault-tolerant quantum computing and revolutionize concepts for designing quantum computer processors. The ONISQ program began in 2020 seeking...

NASA’s Webb Identifies Methane In an Exoplanet’s Atmosphere

NASA’s James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas and water vapor. While water vapor has been detected in over a dozen planets to date, until recently methane – a molecule...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
