The hyperloop has finally carried human passengers. Virgin Hyperloop conducted a test in the desert outside Las Vegas, with two people traveling in a pod through a nearly airless tube at 100 mph. Therefore, engrafted emitters on the metallic substrate consist of the original CNTs in the paste and the catalytic grown ones. The metallic substrate was fabricated as the cathode into the vacuum-sealed diode tube (See Fig. 2.) and the vacuum level in the tube was kept below 5 × 10 − 5 Pa. The anode is one copper pole with the water cooler . I can’t not mention tube bag because it is just that good. It is just what it sounds like – vacuum bag in the form of a lay-flat tube. It comes in diameter from 100mm / 4″ to 1.2m/4′ and in a variety of bag materials. It is perfect for sliding items into for envelope bagging.
