The Paik Nam June Media Bridge project—in Seoul, Korea—is more than a kilometer long (0.67 miles). It has museums, libraries, and shopping malls, but what it really needs are anti-gravity engines so it could fly to orbit.

Those ramps are not engines of any kind, however.(…)

Even the most efficient solar cell loses a lot of energy in the form of wasted heat. But the electron-like particles that photons emit as they enter the cells could be turned into electrical energy, solving the heat loss problem.

When photons, the particles of light,(…)

Look at the giant bubble-wrap that’s going to encircle these identical 25-story towers. OK, OK, it’s actually a honeycomb screen that helps reduce cooling needs. The Abu Dhabi Investment Council sure is lucky to get such shiny, swank new headquarters.

In the nighttime view, it’s easier(…)

Lasers have recently shown they can down a UAV–but they can also keep the drones up in the air. LaserMotive has kept a 22-gram model helicopter hovering for hours at a time on just a few watts of laser power.

LaserMotive won $900,000 from NASA last(…)

Plants are extremely efficient converters of light into energy, setting the bar for researchers creating photovoltaic cells. A team of MIT scientists believe they’ve created a synthetic chloroplast that can be broken down and reassembled repeatedly, restoring sun-damaged solar cells.

While the leaves on a tree(…)
