GravityLight addresses the fact that more than 1.5 billion people on the planet have no access to reliable electricity. The clean, green LED lamp only requires users to lift a 20-pound weight every 30 minutes. As the weight descends the attached tracks, it powers an internal dynamo which in turn lights the light. It’s the same concept we’ve seen used with hand-cranked gadgets for years, just with less overall effort required of the user thanks to gravity’s help.

The system works like this: Urine is put into an electrolytic cell, which separates out the hydrogen. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas. This purified hydrogen gas is pushed into the generator. 1 Liter of urine gives you 6 hours of electricity. (via A Urine Powered Generator : Maker Faire Africa)

In an effort to debunk tradition and reduce the use of the world’s oil supply—Indian auto manufacturers Tata Motors has planned to release a car powered by compressed air. Called the ‘Tata Airpod’, the tiny car’s engine works by extracting air pressure from its 175-liter tank—and does not contribute to air pollution. Using technology developed by MDI, the car’s tank can be refilled through a charging station, or take in air while driving with the help of its electric engine—for a full tank, it takes two minutes to refill. The Tata AirPod is able to travel at a top speed of 28 to 43 mph (45 to 70 kmh)—and travels up to 200km on a full tank. (via A Car That Runs On Air: The Future Is Here? - DesignTAXI.com)

Created by Aerofex, the rotocraft uses helicopter dynamics to lift and propel this motorcycle-sized vehicle across rough terrain. The vehicle’s first test flight occurred back in 2008, but ultimately ended in flames. But after years of improvements and field-testing, the vehicle has finally achieved driving stability with the ability to execute sharp turns and hover in place. The latest iteration of the vehicle can fly up to 15 feet in the air and reach speeds of 30 miles per hour. (via Star Wars hover bike rides into reality from the Mojave Desert | DVICE)

Contour Crafting uses what is essentially a giant 3D printer that hangs over the space the home will occupy, building up the walls using layers of concrete. The machine can add plumbing and electrical wiring as it goes, leaving a completed shell needing just windows and doors to complete. There are even ways to robotically paint the walls and add tiling to floors and walls. (via Build a custom home in 20 hours using a giant 3D printer | DVICE)
