This is the battery-powered VC200 “volocopter,” a state-of-the-art helicopter prototype by engineers at German start-up e-volo. From Smithsonian Mag

In the coming year, engineers will continue working on the prototype, which the company boasts will be lighter, safer, quieter and greener than any other helicopter in the world.

That’s because a traditional helicopter uses one rotor to provide lift and a tail rotor to prevent the aircraft from spinning in circles. It maneuvers by changing the pitch of the two rotors. The volocopter has 18 small rotors mounted in a configuration that provides lift without causing the vehicle to spin. It navigates by changing the speed of individual rotors.

e-volo also invented this previously-featured, e-powered multicopter. Related watching: more helicopters, including human-powered ones.

How can the physics and engineering of wind and water change a country? From the world of European travel guides, here’s a quick primer: The Netherlands: Working Windmills.

300 years ago, half of what we know as The Netherlands was under water. Slowly, the former seabed was reclaimed and the Dutch went to work drying the ground with the country’s leading natural resource - the wind. Over 1000 windmills, some still functioning, survive in the Netherlands today, reminding locals and tourists alike of the clever engine that powered the creation of this land.

Either all of these people are quite small or that’s one of the biggest dump trucks in the world. File under: this exists, this is the Liebherr T-284 Ultra Class Mining Truck, 261 tons of off-highway vehicle that’s the size of a house. This video was filmed at the 2012 Minexpo in Las Vegas.

The Verge reports on Anthropomorphism in Robots at the 2014 International CES (Consumer Electronics Show). Anthropomorphism, or personification, occurs when inanimate objects, animals, or things in nature are given human qualities.

There are more robots and more anthropomorphic examples in the archives, including eyebombing, the animated short Omelettethe Otamatone Jumbo, and one of our favorites: Cloudy.
