Hyperloop Transportation Reality Accelerates

Hyperloop One forms new partnerships with global infrastructure giants Welcome to the future. High energy efficiency coupled with electric propulsion yield an energy elegant, carbon free mode of transportation. And to enable on-demand transport, Hyperloop pods are much smaller than most planes and trains and are designed to depart as often as every 10 seconds. Image:…

A New Approach

MIT develops nontoxic way of generating portable power; Battery substitutes produce current by burning fuel-coated carbon nanotubes like a fuse March 14, 2016: The batteries that power the ubiquitous devices of modern life, from smartphones and computers to electric cars, are mostly made of toxic materials such as lithium that can be difficult to dispose…
