Why Hyperloop is still a deadly scientific fantasy Conceptual image of inside a hyperloop pod. Can you say claustrophobic! With three test tracks and a empty passenger pod built the hyperloop hyperbole is building. What are the real dangers and challenges with the hyperloop theory? I like the simple definition of Hyperloop in RationalWiki - " It involves a tube evacuated to very low pressure in which pods are propelled forward, using magnets, at speeds in excess of 1000 km/h. In essence it is a pneumatic tube on steroids or a magnetically levitated train inside a vacuum tube." The technology currently does not exist except as a theoretical concept. In Canada, Transport Canada has begun a study to evaluate hyperloop. The fact is over 22 studies have been done on high speed rail in this country and we still have no high speed trains although it is a proven safe technology for over a half a century. So why spend taxpayers money on looking at hyperloop?  There ...
