Electric Buses – Batteries instead of overhead wires?

I’ve always believed that the big breakthrough in public transit would come from eliminating the restrictions of a fixed power grid. So, the Proterra battery-powered bus might be the right direction.

Electric cars might be sexier. But Ryan Popple, who was an early employee at Tesla, is now convinced that electric buses are more interesting.

Proterra, the startup Popple runs, designed a sleek new electric bus that drove 258 miles on a single charge in a recent test. That’s farther than most tiny electric cars can go and also farther than a daily city bus route.

Why NASA Didn’t Just Send Over A Rover To Look For Water On Mars

Mars is basically a pretty arid place, so it’s pretty astonishing that the Mars Reconnaissance Orbiter was able to spot signs of liquid water on the planet’s surface.

But even more astonishing in a way is that one of the places where signs of water was spotted is a mere 50 kilometers from where NASA’s Curiosity rover has been exploring. After all, Mars is a pretty big planet, and signs of water have been spotted in only a handful of places.

The curious case of whistled languages

Whistled Turkish is a non-conformist. Most obviously, it bucks the normal language trend of using consonants and vowels, opting instead for a bird-like whistle. But more importantly, it departs from other language forms in a more fundamental respect: it’s processed differently by the brain.

What people in 1900 thought the year 2000 would look like

The series of paintings, made by Jean-Marc Côté and other French artists in 1899, 1900, 1901 and 1910, shows artist depictions of what life might look like in the year 2000. The first series of images were printed and enclosed in cigarette and cigar boxes around the time of the 1900 World Exhibition in Paris, according to the Public Domain Review, then later turned into postcards.
