Real Engineering looks at the economic and physical challenges of supersonic flight, and how Boom, a high tech startup hoping to bring back these faster-than-sound planes as a method of rapid, luxury transcontinental flight.
Future Interfaces Group shows off Electrick, an intriguing way to convert virtually any sort of object into a touch-sensitive surface using conductive materials or sprays, and connecting an array of electrodes. It’s not as precise as a touchscreen, but it can sense X/Y positions.
Stuff built from carbon fiber looks cool, but what makes it so amazing is its incredible ability to be manipulated to serve a variety of lightweight structural needs. Real Engineering takes a look at this awesome woven material and explains what makes it so work so well.
Korean firm ETI Co Ltd. has developed a road barrier that could dramatically reduce the degree of injuries from collisions. The trick is that it helps disperse impacts into rotational energy along its conveyor-like rollers. Though it could send cars flying back into traffic.
This marvel of modern engineering at China’s Three Gorges Dam is capable of lifting 6.7 million pounds of boats, water, and people to a height of over 34 stories. It takes 40 minutes to get to the top, shaving more than 2 hours off of the previous route over the dam.
Start out with a 360º ride through Switzerland’s Gothard Base Tunnel, then take a tour of the myriad platforms, elevators, and walkways that surround the 35.5 mile long tunnel that runs through the base of the Alps. The video is narrated in German, but it’s self-explanatory.
If you’ve ever used that spray foam insulation, you know how insanely the stuff expands when exposed to air. Watch how Polylevel puts these properties to good use, as a similar foam manages to raise heavy slabs of concrete and sidewalks like nobody’s business.
It used to be that most airplane wings were straight, but it turns out the design caused instability as flight speeds increased. Real Engineering takes a look at the science behind the swept wing design which is commonplace on today’s planes. Learn more here.
