The best inventions of 2005

Time magazine has just introduced the best technology innovations of 2005, from clean motorcycles, smart ropes . to personal water purifiers.

Super speed bike: This ENV car looks really muscular. Weighs 100kg and is made of aluminum, the car can reach a speed of 80km / hour thanks to the engine powered by hydrogen batteries. Project director Andy Eggleston said the proprietary technology allows fuel cells to generate more energy than normal batteries.

ENV runs smoothly with a hydrogen tank weighing about 150g ($ 4 / bottle). Such a bottle can help the car run 160km. Intelligent Energy says it will go on sale in 2007 for less than $ 10,000.

Smart ropes: Ropes can save firefighters or climbers as long as they are not frayed or abruptly cut off. For added security, experts at the Squid Labs Laboratory in the US have built a rope with conductive metal fibers. The wire can detect the weight it is carrying and warns users whether the payload is too large through a message.

Smart cords can also be used to anchor boats, tie valuable items or in rescue operations.

Laser labels for agricultural products: Instead of using paper labels, more and more packaging and distribution companies are testing the use of natural light as labels. In fact, this is a new technique that uses lasers to engrave information such as origin, types . on the skin of fruits and vegetables without making them dark or rot.

Inventor Greg Drouillard (USA) tested this technique for pears. As a result, the laser-labeled area is completely edible. This technique helps suppliers of goods to write more specific information, such as when pears reach a sufficient level to eat .

Taste of anti-fat: Chef David Burke of New York City created 18 flavors that smell like high-calorie foods.

Made from natural or synthetic ingredients, these flavors do not contain fat or calories.

A typical flavor of this flavor has chocolate. The price of each bottle is $ 5.95.

Funny robot: Japanese firm ZMP is selling a robot for $ 7,000. Nearly 40cm tall, Nuvo bipedal robots are capable of dancing, talking, playing music, announcing time and even shaking hands.

Nuvo, meaning '' Let's dance '' , can react to 40 simple commands in Japanese and take photos with a camera mounted on top and pass it to your mobile phone. 15 motor mounts in the body help Nuvo perform fun games such as banana plantation, turn head and walk freely in the house.

Personal water purifier: In early 2006, Switzerland's Vestergaard Frandsen will launch a water purifier for about 3 dollars. Called LifeStraw, the tube contains seven types of filters, including meshes, activated carbon and iodine.

Tubes can prevent waterborne diseases such as typhoid and diarrhea - the perpetrator kills at least 2 million people a year in developing countries. LifeStraw can also create safe drinking water for visitors, victims of storms, earthquakes .

Nemo tent: At $ 395, this Nemo tent can be inflated thanks to a foot pump, without the need for aluminum poles like a conventional tent.

This is a product of Cam Brensinger - a consulting firm for NASA in a space suit design project.

The Nemo tent shows that space technology has been applied to everyday life. The company said the tent could be erected in less than a minute.

Automatic doors: Designed in Japan, this door is only open so that its shape matches the shape of the person or object passing. This feature saves energy, maintains a constant temperature in the room and can prevent dust or other materials from getting inside.

In addition to people, doors can be used for small objects, such as parcel or garage access.
