50 Best Inventions In 2009 (Four)

23. semi mechanical beetles

The Pentagon in the United States is funding a team of engineers at University of California, asking them to invent a way to remotely control beetles flying.

Leading engineers Mike Mahabi and Misaki Sato Takashi can control these small objects to take off, circling, or even return to the manipulator by embedding tiny radio antennas and electrodes into insect optic nerve leaves, flying muscles and brain.

These bad beetles have to carry a tiny battery on their backs.

24. violin in time and space

In September 1st this year, a group of experts were asked to judge the quality of the 5 violins by ear instead of eye.

One violin was made in modern times, but it was specially handled by Professor Francis Schwartz of Switzerland.

As a result, 113 professional listeners in the audience thought that Schwartz's violin was genuine, and only 39 tickets were genuine.

There was a theory that the violin produced by Mr de la Di Wali was the best quality because the climatic conditions of his age produced the best wood quality.

25. Nissan pure electric vehicle leaf

This is not the world's first electric vehicle, but the world's first volume oriented pure electric vehicle for the global market.

Nissan's leaf, which was released in August this year, has a maximum speed of more than 145 kilometers per hour and can run 160 kilometers in the case of electricity.

The plant, which is located in southwest Tokyo, will start production next autumn and will produce 50 thousand leaf a year.

26. machine Penguin

Inspired by the beautiful and smooth swimming posture of penguins, the Forster engineering company in Germany has developed a machine Penguin aquapenguin.

Aquapenguin, like penguins, can quickly soar under water, can pass smoothly or turn around in narrow places, and they can even swim backwards.

27. Honda u3-x unicycle

Honda's u3-x "personal mobile device" employs the omni-directional mobile technology of the famous robot ASIMO of the company. The driver only needs to adjust her gravity center to operate the u3-x unicycle in any direction.

U3-x has a maximum speed of 6 kilometers, less than 10 kilograms, and can run for an hour when it is full of electricity.

28.youtube music master

Kutman, the Israeli musician, spent two months building his thruyou website. The YouTube maniac intercepted all the music playing videos he could find from the world's largest video website, and then cut them into a perfect hodgepodge with his magic scissors hands, which could be the best decadent magic Award for youtube. It also made Kutman a popular Internet celebrity.

29. dandelion rubber

Scientists have known for a long time that the seeds of dandelion contain rubber. But because the seeds of Taraxacum mongolicum seeds mature slowly, they gradually exudate and solidify in the air. Dandelion rubber is very difficult to extract.

Scientists at the flo Hall Institute adjusted a key enzyme in dandelion, thereby changing this characteristic, making the rubber extracted from dandelion seeds more efficient than 5 times.
