The video below is an explanation of the Hyperloop, the futuristic mode of transportation in which passengers climb into pods that travel at speeds of up to 700 MPH though tubes with very low air pressure.

Here’s a report on the EV adoption curve that discusses its limiting factors, e.g., technical limitations, production challenges, and consumer uncertainty.
Yes, the industry is experiencing a 50% per annum growth rate, which sounds great until one realizes that 50% of a small number is itself a small number. (more…)
