The Hyperloop is a large pneumatic tube, similar to the system used by some hospitals to transport documents, samples and medications in a more efficient manner. New York City also relied on a network of pneumatic tubes to transport mail during the first half of the 20th century. Elon Musk unveiled the first sketch of his long-teased Hyperloop transportation system. For human travel, Musk plans to mount a large fan to the front of a pod, which would re-direct high pressure to the rear of the capsule, facilitating even higher speeds. The cost of the project has been estimated to fall between $6 billion and $7.5 billion. Musk has not only spent his week re-imagining how we may travel in the future, but he is also doing his part to keep humanity safe from a potential robot uprising by donating $10 million to the Future of Life Institute for research on how to keep artificial intelligence safe. He has previously expressed his concern about robots, saying artificial intelligence has the potential to be "more dangerous than nukes." Sponsored Content by Taboola
