The Future of Smart Cities

A new technique produces long-lasting movies of nonluminous objects with just a few hundred femtoseconds between frames.
When the Wright brothers pioneered their first flight in 1903, they dreamed of transforming the way our world connected. It’s safe to say they would be astonished at the progress of aviation. From that 59 second flight traveling a distance of 852 feet, we have established a world where there is an airport in nearly every major city, giving people the opportunity to see the globe in ways the Wright Brothers dreamed of.
Scientists have taken a major step towards creating an aircraft of the future, one powered by an ion drive rather than using moving parts and fuel like conventional aircraft.
In a paper published today in Nature, a team led by Steven Barrett from the Massachusetts Institute of Technology (MIT) described how they created a so-called electroaerodynamic-powered plane, one that uses solid-state propulsion, meaning no propellers or jet engines with expendable fuel.
“The future of flight shouldn’t be things with propellers and turbines,” Barrett says in the video below. “[It] should be more like what you see in Star Trek, with a kind of blue glow and something that silently glides through the air.”
