Maglev track could launch spacecraft into orbit


An interesting proposal from the scientists that brought us the Maglev, “ Currently, launching 1 kg (2.2 lb) of payload into LEO by costs about $10,000. The researchers estimate that StarTram could do the same for just $50. For space travelers, Startram could decrease the cost from $20 million (the current cost of sending a person to the International Space Station) to about $5,000.”

Michio Kaku: We’re Born Scientists But Switch to Investment Banking (and More Culture Around the Web) | Open Culture


MK quotes:”I have nothing against investment banking, but it’s like massaging money rather than creating money. If you’re in physics, you create inventions, you create lasers, you create transistors, computers, GPS. [If you’re an investment banker, on the other hand] you don’t create anything new. You simply massage other people’s money and take a cut.”
