Now, charge your mobile phone while you walk

Scientists have developed a new device that can generate electricity from your body movements to power your mobile phone.

The device built by researchers from the Georgia Institute of Technology consists of four discs layered on top of one another.

The first disc is made of copper, and rotates. The next is a polymer and remains stationary, and the third is a gold layer that is divided into sectors, with alternating sections cut out, to make something that looks like a bicycle wheel. The last layer is made of acrylic.

When the copper disc rotates, positive charges in the copper move past the negative charges in the polymer. This causes an imbalance of charges in the gold layer, with each "spoke" of gold having either more positive or more negative charges.
The imbalance means that when a wire is connected between sectors, a current flows.

The team led by researcher Zhong Lin Wang said the device can generate power as long as something causes the copper disc to rotate.

The device works on the same principle as static electricity. For example, when you walk on a rug in wool socks, electrons build up in the socks (and in you), and when you touch a metal doorknob, they jump from your finger, making a spark, 'LiveScience' reported.

Wang said the new device is more efficient than a traditional generator, at least for its size.

A generator works by moving either a wire through a magnetic field or a magnetic field over a stationary wire. Either one requires a certain number of turns of wire to make a certain voltage, plus a strong magnet.

However, the device the researchers created can be made thin and flat. The prototype demonstrated by Wang was about 10 centimetres across, and swinging it in the hand generated enough electricity to power a small array of lights, or about 5 volts, which is enough to charge an iPhone.

Wang said the device is 50 times more efficient than a traditional generator of the same size.

The details of the device are published in the journal Nature Communications.

Which Indian technology companies are doing the most interesting projects?

Let me take a crack at this. These are companies in Pune that I know about, who are using technology in an interesting and different way. I'm sure there are many more (and I am not even counting companies doing "normal" products, but are doing extremely well (like druva.com)).

• TouchMagix.com is selling a product that can convert any flat surface (wall, floor, table) into an interactive "touch" screen.
• LinguaNext.net has software that can localize any software (i.e. change the language) without requiring access to the source code. So they can take an exe file of a program whose interface is in English and give you a Hindi exe back.
• SIRDPune.com takes geographic data and computes availability of water, water table and other such factors for government policy makes. The same base data can be used by banks at rural areas to determine pricing of agricultural projects (so that they can determine loan amounts)
• SMSone.in creates 1000-people "sms newspapers" in small villages (or slums in cities) - i.e. news and ads for a very small locality using only sms. They're in 500+ villages.
• Pubmatic.com allows a website owner to automatically choose the best ads to place on webpages (from various ad networks like google ad words) after estimating which one is likely to give the best payout. This is done on a per ad impression basis
• Airtightnetworks.com - has a number of interesting products in wi-fi security space.
• FinIQ.com - software products for pricing of options, derivatives and other complex financial instruments; customers are banks in South-East Asia and Europe.
• Sofomo.co.in - which is building mobile, internet connected medical diagnostic devices (like ECG), for the Indian market
• AppSurfer.com - which allows users to try Android apps in their browser before they have to buy/download the app on to their mobile.
• There are a bunch of companies that do software for drug discovery and protein folding etc. (like vlifesciences.com; I'm sure there are others, but I'm not very knowledgeable about this area)
• <to be continued>

This is just the first few companies that came to mind. I'll think of more later. This includes only "pure" Pune companies (i.e. does not include companies headquartered elsewhere, but which have development centers in Pune).
