A Bicycle Made Of Cardboard (featured above)
Alfa bike I.G. Cardboard Technologies, Israel
Israeli inventor Izhar Gafni recently developed a low-cost, eco-friendly bike made almost entirely of recycled cardboard and rubber. Tight folding of the cardboard gives the frame sturdiness, and the material is treated with waterproof resin so the bike won't turn into mush when it rains. Gafni hopes to have the bikes in production by 2014, with a price of about $20 each.
A Lamp Powered By Weights

Turns out there's another green source of energy: gravity. Therefore, a product design firm in London, recently invented the GravityLight. Co-founder Martin Riddiford and designer Jim Reeves spent four years developing the light in their spare time. The hanging device hooks to a bag filled with 20 pounds of material, such as sand. Lifting the weight for a few seconds, then letting it drop, creates enough energy to power the light for 30 minutes. The team, which recently raised nearly $400,000 on Indiegogo, is producing more than 1,000 lamps to give away in India and Africa.
A Virtual Coach For Job Candidates
Jizen i-maginer, France
I-maginer, based in Nantes, France, is developing technology to help job candidates be less nervous during interviews. The company, which makes 3-D simulation software, recently created Jizen, a program that simulates a job interview. Jizen features a computer-generated interviewer who peppers the user with questions. As the interviewee responds, Jizen uses a webcam and wearable sensors to analyze the user's body language, facial expressions, breathing patterns, and heart rate. Afterward, the program shows users when they displayed signs of nervousness. I-maginer plans to launch similar simulations to aid with public speaking and stress management.

Moneual, an electronics manufacturer, has a new take on the smart watch. The company is making a device for the deaf that alerts the wearer about important sounds. The watch uses audio recognition to detect things such as ringing doorbells, crying babies, and dinging oven timers. Then, it vibrates and flashes a message on the LED display ("Honk! Honk!" for a car horn). The device, which is still in the prototype stage, won a "best of innovations" award at this year's Consumer Electronics Show.
