50 Best Inventions In 2009 (Six)

38. folding loudspeaker box

The origaudio agency in Chicago sent a gifted answer to the weight problem of speakers. The power is only one of Watt's cardboard speakers. The square speakers are only 7.6 centimeters long, light and not occupied. They can be packed into the slot of laptop bags after they are opened, and they can only get a pair for only 16 dollars.

39. flying rat

If a few mice can't find the north, they may be able to master the key to safe space travel.

NASA's Jet Propulsion Laboratory is trying to use a magnetic field to allow rats to float in mid air to simulate weightlessness in space.

The results of the experiment will tell scientists how to avoid astronauts' weight loss and how to adapt to long-term space life.

40. food racing

The world's first food racing car has been made by the University of Warwick in the UK: its steel wheels are fused with carrot fiber, with potato starch in the mirror, and the cashew shell in the brake board.

It is worth mentioning that this special racing car is driven by Biodiesel Blended with chocolate and vegetable oil.

In addition, the cooler is coated with a special material, which has the "special function" of pforming ozone emissions into oxygen.

41. super swimsuit

Italy swimsuit brand arena has developed a high-tech swimsuit that can exceed the speed of "flying fish".

In this summer's Rome World Championships, German swimmers Paul Biderman wore this super swimsuit to participate in the 200 meter freestyle freestyle, which allowed Phelps to taste the first defeat in individual competitions in 4 years, but this series of super swimsuits has not been allowed to be used in international competitions.

42. high speed helicopter

The fastest helicopter today can barely reach 290 kilometers per hour.

Helicopter manufacturer Sikorsky has developed a x2 technology helicopter that breaks through the "glass ceiling" of the hour.

X2 can speed up to 467 kilometers per hour while ensuring the stability of the fuselage. This speed is almost comparable to that of a small turbojet.

43. eyes

At the age of 9, Canadian producer Rob Spence, 37, was injured and his right eye was permanently damaged.

This year, with the help of many scientists, spears installed a false eye with a super miniature camera. This special eye will record all things seen by spears in video form and become the first "eye begger" in the world today.

44. spider silk

This year, British textile expert Simon Pierre and American fashion designer Nicholas Godley presented a 3.4 Metre long spider silk to the world.

The spider silk was made in Madagascar, an African island country. It used millions of unique local golden spiders, and it took four years to make them.

45. the king of paper airplane

In April of this year, takuotoda, chairman of the Japan Paper Aircraft Association, set a world record for the longest flying time of paper airplanes, 27.9 seconds.

Takuotoda also successfully persuaded the Japan Aerospace Exploration and development agency to invest 90 million yen in the next three years to support toda in sending paper airplanes to space to study lighter and safer spacecraft.

46. smart bullets

High tech bullets should be able to point out where to fight.

Where, and this is the original intention of the US Army developing xm25 launcher launcher, which can explode in mid air, so that the enemy hiding behind the bunker will lose its combat capability.

The operator can program the bullet implanted in the microchip to launch it to the target, and control its distance by controlling the number of revolutions in the gun chamber, so that it can explode in a precise position in the air.

47. 3D camera

Fuji Corp launched the world's first 3D camera this year.

The 10 megapixel vanguard camera has two cameras. It imitates human eyes in a distance. It can take pictures of the same object at different angles at the same time.

48. new varieties of cloud

Members of the international view cloud Association have been in a carnival this year. Since 1951, "cirrus circa" has been included in the "international cloud map", this is a new cloud that has been recorded for half a century.

49. steam rocket vehicle

In August 25th this year, Charles Bernetus, a British driver, broke a record that lasted for more than a century, driving a car like a rocket.

The steamed car also has a lovely nickname: the fastest kettle in the world.

50. machine bride

The robot HRP-4C, which is 1.6 meters tall and weighs 43 kilograms, has many girls' dream perfect bodies.
