Elon Musk's Hyperloop: Shit's gettingreal-ish

Hyperloop Transportation Technologies plans to break ground on a section of Elon Musk's Hyperloop early next year. From National Geographic:

This (five mile) stretch, near the new town of Quay Valley along Interstate-5 midway between Los Angeles and San Francisco, is estimated to cost $100 million and could start carrying passengers in 2018 after extensive safety testing.
