Tokamak Energy, the Oxfordshire-based private fusion energy venture, has announced that its ‘ST40’ spherical tokamak reactor has achieved plasma temperatures of over 15 million degrees Celsius, hotter than the centre of the Sun.
A team of researchers from MIT has come up with a novel way to convert temperature fluctuations into electrical power. Instead of requiring two different temperature inputs at the same time, this ‘thermal resonator’ system takes advantage of the swings in ambient temperature that occur during the day-night cycle.
Researchers have long pondered the origin of delicate crisscross faceted patterns that are commonly found on the surfaces of broken material. Typical crack speeds in glass easily surpass a kilometre per second, and broken surface features may be smaller than a millimetre. Since the formation of surface structure lasts a tiny fraction of a second, the processes generating these patterns have been largely a mystery.
The chemical industry is turning CO2 into high-performance plastics after a European joint initiative was launched. The consortium of 14 partners from seven countries, led by Covestro, plans to investigate how CO2 and other waste gases from the steel industry can be used efficiently and sustainably to produce insulating materials and coatings.
Vodafone has created a unique virtual reality (VR) experience using waterproof VR-goggles to allow divers to experience the thrill of swimming with sharks. As part of a technology event in the Netherlands, divers went under water with virtual South-African Great White Sharks, all hosted in a swimming pool.
