Chinese researchers have made public a new maglev train prototype they developed. Running on high-temperature technology, the high-speed train will run on liquid nitrogen which is much cheaper than liquid helium.
Chinese officials and press received the prototype last week in Chengdu. Southwest Jiatong University hosted the unveiling and witnessed test runs.
The prototype has leveraged several new technologies; such as a low-resistance locomotive shape, a light-weight carbon fiber body, and a superconducting maglev with a capacity for both high-temperature and large load.
Traditional railway trains run on wheels but maglev (also referred to as magnetic levitation) trains are propelled above a guidance track. The Southwest Jiatong University is the birthplace of the superconducting maglev technology.
From the 1980s, the school has worked to advance technological innovation and theoretical research. The university partnered with China Railway Group Limited, China Railway Rolling Stock Corporation and other companies and institutions in 2020 to begin on the prototype’s manufacture. Other than that, they needed to manufacture the test line and build the train’s transit system.
Wu Zili, a senior engineer in SWJTU, was interviewed by the South China Morning Post. He mentioned the train’s systems achieved superconductivity at about one-fiftieth of what liquid helium systems cost. He explained that ordinary superconductors required -269 degrees Celsius while high-temperature superconductors could only work with liquid nitrogen at -196 degrees Celsius.
The engineer added that the train had a self-maglev feature. The train was capable of remaining suspended without extra energy. The train is intended to move at a record speed of 385mph (800km/h.
Future editions of the train are expected to rise to a speed of 500mph (800km/h) because of low vacuum tunnel technology. Trials for an even better maglev prototype were running last year at Shanghai Tonji University.
SJTU is working on other innovations besides the maglev train. An urban rail vehicle running on wireless power supply is also in the works.
The Future of Road Safety
In the wake of a tragic accident in Las Vegas that claimed nine lives, the National Transportation Safety Board (NTSB) has reignited a crucial conversation about road safety. The board’s recommendation for all new vehicles to be equipped with Intelligent Speed Assistance (ISA) technology, as reported by NBC News, marks a significant step towards reducing the alarming rate of speeding-related fatalities on U.S. roads.
Understanding ISA Technology
ISA technology is not a novel concept; it has been a subject of discussion and development for years. Unlike traditional speed limiters that impose a flat speed cap, ISA systems use GPS and sign recognition to adapt to the speed limits of different zones, effectively preventing vehicles from exceeding these limits. This technology represents a more dynamic and context-sensitive approach to managing vehicle speed.
The Road Safety Crisis
The urgency of implementing ISA technology is underscored by the harrowing statistics of road fatalities. In the U.S. alone, over 12,000 people lost their lives in speeding-related crashes last year, with hundreds of thousands more injured. Speeding remains a common factor in auto fatalities, making it a critical target for intervention.
The Hurdles to Adoption
Despite the clear benefits, the adoption of ISA technology faces several challenges. The NTSB’s recommendation, while influential, does not carry regulatory or enforcement power. The National Highway Traffic Safety Administration (NHTSA), which oversees vehicle safety standards, has yet to adopt this recommendation. Moreover, the response from auto manufacturers has been tepid. The Alliance for Automotive Innovation, representing most domestic auto manufacturers, emphasizes driver education and awareness over technological interventions.
The Argument for ISA
Advocates for ISA technology argue that traditional approaches to curbing speeding, such as driver education and awareness campaigns, have not been sufficiently effective. David Zipper, a visiting fellow at Harvard University’s Kennedy School, points out that focusing on car design and integrated safety technology could be more impactful. The idea is to make it physically impossible for drivers to exceed speed limits by a significant margin, thereby reducing the risk of high-speed accidents.
The Broader Perspective
While ISA technology is a promising tool, it is not a panacea for road safety. Experts like Isabella Chu, associate director of the data core at the Stanford Center for Population Health Sciences, advocate for a holistic approach. This includes revolutionizing road design to prioritize the safety of all road users, not just vehicles. However, as comprehensive road redesigns are a long-term goal, ISA technology serves as an effective interim solution.
The Path Forward
The path to widespread adoption of ISA technology is fraught with challenges, including regulatory hurdles, industry resistance, and public skepticism. However, the potential benefits in terms of lives saved and injuries prevented are too significant to ignore. As Chu optimistically notes, if the argument for ISA technology is just and its merits are clear, there is hope for eventual adoption.
In conclusion, the NTSB’s recommendation for ISA technology is a crucial step towards enhancing road safety. While there are obstacles to its widespread implementation, the potential to save thousands of lives annually makes it a pursuit worth advocating for. As technology continues to advance, it is imperative that we harness its potential to make our roads safer for everyone.
