I remember as a child, being dragged along to run errands with my mom. We would go to the market, then the pharmacy, the post office, and finally, the bank. While I would complain about the first three stops, I always enjoyed the last one... Not because I liked the money or free lollipops, but rather for the cool pneumatic tubes at the drive-thru. I would sit back in wonderment over how the little vessel could traverse between the teller and customer by what seemed like magic. And while I would later learn that the force behind these tubes was based less in sorcery, and more in physics; I still find the concept to be cool and useful... and apparently I am not the only one.
Take Elon Musk. The South African entrepreneur and inventor who, beyond having a really cool name, is trying to change the world. He has found great success in his ventures; first with Zip2 and PayPal, then SpaceX and Tesla Motors. Now, with his newest undertaking, Mr. Musk is attempting to redefine global transit by designing and implementing the Hyper loop.
