The Solar Impulse 2 is to be officially presented today, but its construction didn't happen in a day. Watch this video and understand the steps that had to be taken when you're looking towards attempting the First #RTW Solar Flight!

It's a little shaky but if you average out the oscillations I think the result is clear. Again, huge thank you's to A/Prof Emeritus Rod Cross, Helen Georgiou, Alex Yeung, and Chris Stewart, the University of Sydney Mechanical Engineering shop, Duncan and co. Ralph and the School of Physics.

he White Salmon River in Washington state is flowing again as the nearly 100-year-old Condit Dam was disabled with explosives Wednesday. The reservoir draining took about 2 hours. Further demolition is scheduled in 2012. The event is a significant milestone for river restoration and dam removal nationwide.

Watch Richard Ambrose and Jonny Phillips quickly construct a building made of concrete canvas-a material that has all the elements of concrete, but is flexible enough to be turned into any shape. This technology allows people to erect permanent structures in a fraction of the time needed for traditional building techniques.

Watch never-before-seen videos of an MIT-developed lubricant called LiquiGlide that makes anything--syrup, ketchup, paint--slide right out of the bottle so you don't waste a drop. The applications start in the kitchen, but they extend into almost every industry. More Videos

Droplets, pellets, a stick of wood, nuts, screws, diodes, if the object in question is small enough, than this machine can not only lift them into the air and hold it in place, but move them around on all three axes

It takes strength, skill and, most importantly, intellect to erecting intricate webs of sky-high walls and platforms strong enough to hold a legion of construction workers.

The Super Awesome Micro Project: A full sized Lego car, with an engine made from Lego that runs on air.

Glass making demonstration at the Corning Museum of Glass in Corning, NY.

The process of making mirrors from beginning to end.

The show is presented on the Science Channel in the US, Discovery Channel Canada in Canada, and on the Discovery Channel in the United Kingdom.

On June 13th, 2013, the AeroVelo Atlas Human-Powered Helicopter captured the long standing AHS Sikorsky Prize with a flight lasting 64.1 seconds and reaching an altitude of 3.3 metres

This is a video featuring the first ever Raspberry Pi powered espresso machine.

In a robot lab at TEDGlobal, Raffaello D'Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D'Andrea show drones that play catch, balance and make decisions together -- and watch out for an I-want-this-now demo of Kinect-controlled quads.

An old womans bike built for shopping turned into a bomb inspired safety hazzard. This is the final part in my series on the wonderfull pulse jet and what an end.

What can you accomplish in 360 hours? The Chinese sustainable building company, Broad Group, has achieved another impossible feat - building a 30-story tall hotel in 360 hours.

The FLIP (FLoating Instrument Platform) is a research vessel that can rotate to a vertical position. It is currently owned by the Scripps Institution of Oceanography.

So we have all seen a quadrocopter before, but just look at the size and agility of this one. Needless to say that sound is quite scary when it just comes out of nowhere! Turn your volume up for a jumpy ride.

A father who lost his arm in an accident six years ago has been given a new lease of life by a hi-tech bionic hand which is so precise he can type again. Nigel Ackland, 53, has been fitted with the Terminator-like carbon fibre mechanical hand which he can control with movements in his upper arm. The new bebionic3 myoelectric hand, which is also made from aluminium and alloy knuckles, moves like a real human limb by responding to Nigel's muscle twitches. Incredibly, the robotic arm is so sensitive it means the father-of-one can touch type on a computer keyboard, peel vegetables, and even dress himself for the first time in six years.

King Fahd's Fountain, also known as the Jeddah Fountain, is the tallest water fountain in the world. Located in the coast of Jeddah, west coast of Kingdom of Saudi Arabia. The fountain jets water 312 metres (1,024 ft) above the Red Sea. It was donated to the city of Jeddah by King Fahd, hence its name. The fountain is visible throughout the entire vicinity of Jeddah. The water it ejects can reach a speed of 375 kilometres (233 mi) per hour and its airborne mass can exceed 18 tons. It was constructed between 1980 and 1983 and began operating in 1985. The fountain uses saltwater taken from the Red Sea instead of freshwater. It uses over 500 spotlights to illuminate the fountain at night.

This is the streamlined, two-person watercraft that breaches and submerges just like the Orcinus orca after which it is designed. A pilot protected beneath its watertight 1/2"-thick acrylic canopy pushes and pulls twin control levers to articulate the whale's pectoral fins for rolls and stealthy dives. With a finger on the right lever's throttle trigger, steering is provided by dual foot pedals that control the vectored thrust of the craft's 255-hp supercharged Rotax axial flow engine, enabling realistic behaviors such as porpoising or skyhopping.
