 | How a NASA engineer created the modern airplane wing
Once dubbed "the man who could see air," NASA engineer Richard T. Whitcomb used a combination of visualization and intuition to revolutionize modern aviation -- by turning the shape of the airplane wing on its head. Today, nearly every commercial airplane bears the marks of Whitcomb's several innovations.

 | Chairless exoskeleton to solve long-standing problem
The Chairless Chair is a new innovation for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. Operating a switch on the strap turns the flexible construct into a stable seat. Two small FAULHABER DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

| | Videos+: Technologies and inspiration in action | Super Hornet cockpit: 'Scrolling' through the battle space
Take a tour of the next-generation touchscreen technology that is the future for the Boeing Block III F/A-18 Super Hornet. The Advanced Cockpit System (ACS) is a 10-in. x 19-in. display that pilots can use the same way we use phones and tablets in our daily lives. (Sorry mechanical switch makers, pushing real buttons is largely a thing of the past. But look at all the space that's been freed up!)

World's first commercial 3D-printed concrete housing project taking shape
Eindhoven, a city in the south of the Netherlands, is the site of a unique 3D-printed housing project called Project Milestone. The first of five planned 3D-printed concrete homes will begin construction this year. After each house is completed, it will be rented out by a leasing company and occupied. The houses feature non-traditional, boulder-like structures and weird shapes, which are perfect for highlighting the advantages and capabilities of this materials-saving new process.

Why do electric cars only have one gear?
Why do electric cars use just a single gear, rather than using traditional transmissions like you'd find paired with internal combustion engines? Electric motors can get away without numerous gears because they are high revving, remain fairly efficient across a very broad rev range, and produce a great amount of torque at low RPM. Jason Fenske from Engineering Explained talks about the pros and cons of electric-car technology and gets into the nitty gritty of gearing.

Pushing the limits of motorcycle design and manufacturing
Matt Chambers, founder and CEO of Confederate Motors, talks about the impact that 3D Systems' Quickparts rapid parts and prototypes service has on his design-and-build business. With the exception of some engine components, wiring, wheels, tires, and lighting, 3D Systems makes every part of the super-boss P51 Combat Fighter motorcycle, saving a tremendous amount of time and hassle for Confederate Motors by being able to consolidate part production with one primary vendor. Quickparts is now part of 3D Systems On Demand Manufacturing.
