See successful flight of a human-powered helicopter
A human-powered helicopter (HPH) is a helicopter powered solely by one or more persons carried on board. As in other human-powered aircraft, the power is usually generated by pedalling. It remains a considerable engineering challenge to obtain both the power-to-weight ratio and rotor efficiency required to sustain a helicopter in flight.

ATLAS robot is approximately 6 feet tall and weighs about 330 pounds. The ATLAS is made out of aircraft-grade titanium and aluminum with blue LED lights mounted inside its chest. The humanoid owes its agility and balance to an onboard computer that receives information from a laser rangefinder and stereo cameras that survey and gauge the robot’s immediate surroundings.
The Kouris Centri-Turbine Generator (Water Vortex Turbine Generator) invented by Paul S. Kouris The idea for the “KOURIS ‘CENTRI-TURBINE’ GENERATOR” came to Mr. Kouris while he was completing his education in jurisprudence/ philosophy in the mid-l970s.

Two Australians have invented something similar to an automated pool cleaner -- but for marinas, harbours, ports and even inland waters like rivers and lakes -- that sucks up garbage, while filtering out the water. They're calling it the Seabin, and it recently was successfully crowdfunded on Indiegogo. Check out how it works:
Amazing invention Sound Extinguish Fire:The fire extinguisher uses low-frequency sound waves to douse a blaze. Engineering seniors Viet Tran and Seth Robertson now hold a preliminary patent application for their potentially revolutionizing device
The first robot, Foundation Robot, shuffles around the footprint of the building on caterpillar-style tracks, following a pre-defined route and using a sensor to steer itself around the shape. Like your standard 3D printer, it squirts out building material, which is made up of 50 percent marble powder and 50 percent polymer for a lightweight but strong substance, in layers.
