50 Best Inventions In 2009 (Three)

15. folding electric vehicle

You can think of it as a mini version of the ferris wheel because you don't need to pedal on it, it will whiz forward.

The folding mini electric car, named yikebike, brings convenience to the workers.

It is reported that the electric vehicle is running at speeds of up to 20 kilometers per hour.

16. vertical farms

The vertical farm was first proposed by Dickson Depomya, a professor of public health at Columbia University.

Valcen, Texas, has become the pioneer of "vertical farm" and has created a revolving hydroponic farming system.

It is reported that rotary design can give plants and vegetables adequate sunshine and nutrition.

In addition, compared with traditional farms, vertical design can make all plants save more water.

The most important point is that vertical farms can grow more plants and vegetables without requisition more land.

17. skin of the earth

This year, NASA and the United States CISCO worked together to develop a global central system called "earth skin".

It is reported that the new global "central system" can link the sensors of sea, land, air and even the space station to collect the tracking and monitoring data of global climate change as much as possible, so as to enable enterprises to better cope with and prevent climate change.

The system, which will be established in 2010, will also monitor the illegal logging of tropical rainforests.

18. cheap intelligent prosthesis

For poor people with disabilities, jaipurknee is their Savior.

The smart limb designed by several students from Stanford University is only $20.

It is worth mentioning that this intelligent prosthesis includes 5 plastic pieces, four hard shells and four screws.

Therefore, there is no need to use special tools when installing, and it can be installed in a few hours.

19. financial product supervisory authority

The purpose of the consumer financial protection agency is to ensure that financial products are not controlled by large enterprises and that the loan agreement provided by the lender to customers is "clean and simple".

20. microorganisms producing electric currents

We should be grateful to some special microorganism. It is Geobacter.

The microorganism created by researchers at the University of Massachusetts can generate electricity from mud and sewage.

According to researchers, the energy output of this new microorganism is 8 times that of ordinary microorganisms.

This new achievement will promote the further development of microbial fuel cells.

21. fans without blades

James Dyson, the inventor, sent us a revolutionary electric fan "air multiplier" without a leaf.

Its working principle is to suck the air from the vent of the base, and then continuously spray it out of the annular gap through a built-in supercharger.

Because there is no fan blade, this fan is safer than the traditional fan, it also keeps the traditional fan tilt, swing and wind speed regulation.

22. "copy" pets

In 1997, when the famous cloned sheep "Dolly" came out, Lo Hoson began to imagine whether he could copy a "copy" for his mother's pet dog "Misi".

In 2007, he founded the company's "bio art" to bring the idea to reality.

In 2009, BioArts cloned the puppies they wanted for 5 customers, priced at $144 thousand each.
