Imagine hefting 200 pounds as though it were a mere 12. Raytheon Company has just released a full-body suit that could make the Iron Man fantasy become a reality.
Called the XOS-2 Exoskeleton, it essentially grants the wearer superhuman strength (and also looks really awesome). The new suit has made significant improvements over its predecessor, the XOS-1, which was first demonstrated two and a half years ago.

Some people choose not to ride a bicycle to work or school because it would simply be too inconvenient; not every place has a bike rack outside, and sometimes the chain grease can make for a messy commute.
Well, now you don’t have to worry about those problems, thanks to a new chainless bike that can be easily disassembled.
Designed by Hungarian engineers, the Stringbike uses two steel cables attached to pulleys, which move on swinging discs as you pedal. The discs replace a traditional round gear system, and they can be changed depending on your needs.

Ever wonder how cars can make turns without skidding? Well, you have engineers to thank – more specifically, those who invented the differential (a device which allows the wheels of a car to turn at different speeds).
This vintage engineering tutorial, made by the General Motors, clearly and engagingly explains how differential gears work. Posted on YouTube last year, it has now received close to a million views – not bad for something made in 1937!

As upsets continue to shock viewers of the US Open, engineers at Prince Sports are watching their patented O-Technology hit winners up and down the court.
The concept seems simple – tiny round, oval, or trapezoidal holes placed strategically along the frame of a tennis racket.
But this subtle design feature has many benefits. Not only does it make the racket lighter, but it also reduces drag and enlarges the area on the strings referred to as the sweet spot.

If you need examples of cool things engineers can do in college, consider this: mechanical engineering students from Ohio State University work together building alternative-fuel race cars as part of the Buckeye Bullet team.
Not cool enough? Well, the team just broke the electric car land speed world record with their most recent vehicle, the Buckeye Bullet 2.5.
Racing on the Bonneville Salt Flats in Utah last week, the Bullet 2.5 reached a peak speed of 320 miles per hour and logged a two-way average speed of 307.66 miles per hour.
