water crisis is over

An important step toward realizing the dream of an inexpensive and simple “artificial leaf,” a device to harness solar energy by splitting water molecules, has been accomplished by two separate teams of researchers at MIT

Scientists have created the world’s first practical artificial leaf that can turn sunlight and water into energy, which they claim could pave the way for a cheaper source of power.
A team at Massachusetts Institute of Technology (MIT) says that the artificial leaf from silicon, electronics and various catalysts which spur chemical reactions within the device,that can be used to  break water into hydrogen and oxygen which can then be used to create electricity in a separate fuel cell.
A practical artificial leaf has been one of the Holy Grails of science for decades. Placed in a gallon of water and left in sun, these artificial leaves could provide a home in the developing world with basic electricity for a day.One can envision villages in India and Africa not long from now purchasing an affordable basic power system based on this TECHNOLOGY.

new technologies

Independent car:Due to shortage of petrol car making companies are making such cars which work without petrol.They run with hydrogen,gas or ethanol,these types are not easily available.But a french company has made a  which work with solar energy .Its name is Venturi.It work with air and solar energy efficiently and if both are not available it can run efficiently with electricity.


Clock in mobile:A Chinese company has invented a wrist watch but it has properties of  a good mobile.It has a GB card,FM,MP3.MP4 player,bluetooth,1.3 megapixel camera and camera.It has a 200k colour lcm screen.Upto 100 to 200 minutes can be talked from it.It can be used in two ways as hand free and bluetooth.It has a small stitch technology.

CARS

1. Bugatti Veyron Super Sports $2,400,000. This is by far the most expensive street legal car available on the market today (the base Veyron costs $1,700,000). It is the fastest accelerating car reaching 0-60 in 2.5 seconds. It is also the fastest street legal car when tested again on July 10, 2010 with the 2010 Super Sport Version reaching a top speed of 267 mph. When competing against the Bugatti Veyron, you better be prepared!

2. Pagani Zonda Clinque Roadste $1,850,000. One of the most exotic cars out there is one of the most expensive. It can go from 0-60 in 3.4 seconds with a top speed of 217 mph.
We have a tie for 3rd place:
3. Lamborghini Reventon $1,600,000. The most powerful and the most expensive Lamborghini ever built is the second on the list. It takes 3.3 seconds to reach 60 mph and it has a top speed of 211 mph. Its rarity (limited to 20) and slick design are the reasons why it is so expensive and costly to own.
3. Koenigsegg Agera R $1,600,000. The Agera R can burn 0-60 in 2.8 seconds, reaching a maximum speed of 235 mph. It has the parts to reach 270 mph, but the supercar is electronically capped at 235 mph. With the completion of certain paperwork, the company will unlock the speed limit for one occasion.
4. McLaren F1 $970,000. In 1994, the McLaren F1 was the fastest and most expensive car. Even though it was built 15 years ago, it has an unbelievable top speed of 240 mph and reaching 60 mph in 3.2 seconds. Even as of today, the McLaren F1 is still top on the list and it outperformed many other supercars.

5. Ferrari Enzo $670,000. The most known supercar ever built. The Enzo has a top speed of 217 mph and reaching 60 mph in 3.4 seconds. Only 400 units were produced and it is currently being sold for over $1,000,000 at auctions.

6. Pagani Zonda C12 F $667,321. Produced by a small independent company in Italy, the Pagani Zonda C12 F is the 5th fastest car in the world. It promises to delivery a top speed of 215 mph+ and it can reach 0-60 in 3.5 seconds.

7. SSC Ultimate Aero $654,400. Don't let the price tag fool you, the 6th most expensive car is actually the 2nd fastest street legal car in the world with a top speed of 257 mph+ and reaching 0-60 in 2.7 seconds. This baby cost nearly half as much as the Bugatti Veyron, yet has enough power to compete against the most expensive car. It is estimated that only 25 of this exact model will ever be produced.

8. Ascari A10 $650,000. This badboy can reach a tested top speed of 215 mph, zooming 0-60 in 2.8 seconds. The British car company plans to assemple 50 of these supercars in their factory in Banbury, England.
9. Saleen S7 Twin Turbo $555,000. The first true American production certified supercar, this cowboy is also rank 3rd for the fastest car in the world. It has a top speed of 248 mph+ and it can reach 0-60 in 3.2 seconds. If you are a true American patriot, you can be proud to show off this car.

10. Koenigsegg CCX $545,568. Swedish made, the Koenigsegg is fighting hard to become the fastest car in the world. Currently, it is the 4th fastest car in the world with a top speed of 245 mph+, the car manufacture Koenigsegg is not giving up and will continue to try and produce the fastest car. Good luck with that!

technology

Technology is the making, usage and knowledge of tools, techniques, crafts, systems or methods of organization in order to solve a problem or serve some purpose. The word technology comes from Greek (technología); meaning "art, skill, craft", and (logía), meaning "study of-". The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology.

Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history.
