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.

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.

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.

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.

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.

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.

Do you want to have your mind blown? Watch this. (This will cost you 13.5 minutes) Hugh Herr, Director of Biomechatronics at MIT University delivers an amazing talk that will touch your soul. I was in the audience. I was almost in the back row. For the opening few minutes of the talk, I couldn't see his feet. So imagine what happened when I finally stood up and saw his legs.

This is what happens when you sync your camera shutter to the speed of helicopter blades.
