Andy Green, the first and only person to break the sound barrier in a car, is set to return to Utah's Bonneville Salt Flats this week with an ambitious goal – to break his own diesel-powered land speed record using a hydrogen-fueled vehicle. The retired Royal Air Force fighter pilot aims not just to earn another accolade but also to demonstrate the potential of hydrogen as a clean energy alternative. Green will be driving the JCB Hydromax, a 32-foot long, bright yellow car powered by two hydrogen internal combustion engines with a combined power of 1,600 horsepower. The event, scheduled for Tuesday, marks an important step in showcasing the capabilities of hydrogen technology and its potential to replace diesel in high-speed vehicles. Green is also targeting world records for hydrogen internal combustion engines and electric vehicles during his attempt. If successful, this will be a significant milestone in the ongoing global trend towards sustainable energy solutions. The Bonneville Salt Flats, a remnant of a prehistoric lake bed, has been a hotspot for land speed record attempts since 1914. Green's attempt comes a year after a fatal accident during Speed Week, underscoring the risks involved in such high-speed endeavors. Despite these challenges, Green is optimistic about his chances and the future of hydrogen technology.
