Silent But Deadly: The EU Wants Electric Cars to Add Sounds for Safety

Last week, the European Parliament ruled that all electric and hybrid cars must add artificial engine noise so that pedestrians can hear them coming.

A Hovercraft That Isn't Afraid of Giant Waves

In order to float across land and water, the giant air-trapping skirt around the base of a hovercraft needs to keep a tight seal at all times.

Finally, Someone Made a Visor For Your Car's Side Mirrors

Most cars have wipers on the front and back windshields, and some even on the the headlights.

Four Insane 60s Military Prototypes That Crashed and Burned

If the music‘s anything to go by, pretty much everyone was on something in the ’60s — and that includes the engineers. BAE Systems has recently dug up some totally batshit-crazy ideas that were seriously being kicked around by its ‘crack’ team of engineers, and they’re both totally ridiculous and dangerously awesome. » 6/18/13 9:00am 6/18/13 9:00am

The Dodos We Made: 26 Propeller-Driven Machines That Cannot Fly

So you think the airscrew is strictly for planes? Guess again. Look at these mighty prop-driven machines created by some of the most talented engineers and designers the world 'round. Sure, they can't fly, but their twisted blades help them wade through water, ice, snow, mud, glide on rails, and rule the road. » 5/07/13 10:00am 5/07/13 10:00am

Pontoon Treads Let This Tank Tear Across Land and Water

Many wonderful things have come out of the US Military's Defense Advanced Research Projects Agency—or DARPA—incuding the internet. But none are as insanely awesome as its new CAAT (Captive Air Amphibious Transporter) which is essentially a tank that floats on water thanks to its oversized inflatable treads. » 8/10/12 11:00am 8/10/12 11:00am

Instructions for Building Your Very Own Awesome, Mario-Inspired Go-Kart

Remember the Chibikart—that awesome, Mario-inspired go-kart built by MIT student Charles Guan? We loved it in an only-an-MIT-student-could-come-up-with-something-this-sweet sort of way. Luckily for us, Guan has just polished off the finishing touches on a newer, more accessible design that he says can be built even by… » 6/01/12 8:00pm 6/01/12 8:00pm
