South Korea Developing 'Near-Supersonic' Train Similar To Hyperloop
The South Korean government plans to unveil a high-speed train that can travel at near-supersonic speeds capable of cutting a five hour journey to just 30 minutes. It's reminiscent of the Hyperloop, a proposed mode of passenger and freight transportation that propels a pod-like vehicle through a near-vacuum tube at more than airline speed. Huffington Post UK reports: According to the Korea Railroad Research Institute, it plans to unveil a "hyper tube" format train in the "not too distant" future. Speaking to the South China Morning Post, the government-owned organization said: "We hope to create an ultra-fast train, which will travel inside a state-of-the-art low-pressure tube at lightning speeds, in the not-too-distant future. To that end, we will cooperate with associated institutes as well as Hanyang University to check the viability of various related technologies called the hyper-tube format over the next three years." While this sounds very similar to the low-pressure concept designed initially by Tesla founder Elon Musk it seems as though the KRRI wants to go even further and create a system that will leave Hyperloop looking like a Hornby set. By throwing all their resources at the project, South Korea is hoping to skip past maglev, a still-new propulsion system that uses electromagnets to actually levitate trains above the air. While this removes some of the friction that comes with using conventional wheels, it still doesn't remove the brick wall of friction that is air itself. By building a low-pressure tube however and placing the train inside it you can effectively create a train that could travel at eye-watering speeds.Read more of this story at Slashdot.
