China Starts Building Double Speed Maglev Test Track

China is building new faster prototype maglev train line. China existing high-speed trains are almost all faster versions of conventional steel wheels on steel rail trains. China only has one 19-mile long high-speed maglev train line from Pudong to the Shanghai International Airport. China has the longest network of conventional high-speed rail in the world. …

Pressure Changes Magnetism and Can Improve Electronic Device Performance

Oak Ridge researchers used pressure to manipulate magnetism in thin film materials used to enhance performance in electronic devices. They used neutron scattering at Oak Ridge National Laboratory’s Spallation Neutron Source to explore the spacial density of atoms and observe how magnetism in a lanthanum-cobalt-oxide film changed with applied pressure. Above – Researchers developed a …

Breakthrough for rechargeable non-aqueous magnesium-metal battery that would be twice as good lithium ion batteries

Scientists at the Department of Energy’s National Renewable Energy Laboratory (NREL) have discovered a new approach for developing a rechargeable non-aqueous magnesium-metal battery. Scientists have pioneered a method to enable the reversible chemistry of magnesium metal in the noncorrosive carbonate-based electrolytes and tested the concept in a prototype cell. The technology possesses potential advantages over …

Magnetospheric Protection from Galactic Cosmic Radiation for long space missions

An optimal shielding configuration has been realized during a phase I NASA NIACstudy, and it is referred to as a Magnetospheric Dipolar Torus (MDT).A This configuration has the singular ability to deflect the vast majority of the GCR including HZE ions. In addition, the MDT shields both habitat and magnets eliminating the secondary particle irradiation …

Advanced Vasimr plasma drives and SpaceX BFR trip times

The Vasimr rocket is on track to a 100-hour continuous firing this summer of the company’s VX200SSTM VASIMR® prototype at a power level of 100 kW. This would produce about 2 newtons of propulsion. It would be superior to current ion drives and would be 10-60 times more fuel efficient than chemical rockets. Some comments …

Toyota has reduced the rare earth materials used in electric vehicle magnets by 50%

Toyota has developed the world’s first neodymium-reduced, heat-resistant magnet. Neodymium magnets are used in various types of motors such as the high-output motors found in electrified vehicles, use of which is expected to increase rapidly in the future. The new magnet uses significantly less neodymium, a rare-earth element (“rare earth”), and can be used in …

China developing faster and slower maglev trains

A new generation of Chinese medium-to-low-speed maglev trains can run at a maximum speed of 160 kph. China will operate five to twelve magnetic levitation rail lines with maximum speed of 160 kilometers per hour in cities including Chengdu, Wuhan and Guangzhou by 2020. More than 12 Chinese cities, including Tianjin, Hangzhou and Shenzhen, are …

China’s planned supersonic maglev transport in evacuated tubes

China Aerospace Science and Industrial Corporation (CASIC) has said it will build a supersonic superconducting magnetic levitation (maglev) tansportation system. Nextbigfuture covered the CASIC announcement a few days ago. There is some additional information about the staging of development plans. NOTE: This is not a hyperloop. CASIC is looking to make partial to fully evacuated …
