Harvesting Energy with every step






















Although you may not be using a Get Smart-style shoe phone anytime soon, it is possible that your mobile phone may end up receiving its power from your shoes. University of Wisconsin-Madison engineering researchers Tom Krupenkin and J. Ashley Taylor have developed an in-shoe system that harvests the energy generated by walking. Currently, this energy is lost as heat. With their technology, however, they claim that up to 20 watts of electricity could be generated, and stored in an incorporated rechargeable battery.

While the details of the energy-harvesting technology are proprietary, it is said to involve a process known as "reverse electrowetting," which was discovered by Krupenkin and Taylor. It converts mechanical energy to electricity via a microfluidic device, in which thousands of moving microdroplets (of an undisclosed non-toxic, inexpensive liquid) interact with "a groundbreaking nanostructured substrate." The process is said to have a power density of up to one kilowatt per square meter (10.76 sq. ft.), plus it works with a wide range of mechanical forces, and is able to output a wide range of currents and voltages.
The battery is hermetically sealed, for protection against water and dirt. In order to get the power from it to the phone or other mobile device, the two would have to be temporarily physically joined with a wire, although the researchers are also looking into the use of conductive textiles and wireless inductive coupling.
Besides directly powering the phone, the device could also serve as a mobile WiFi hotspot, linking the phone to a wireless network. Having its own hotspot constantly nearby could drastically increase the phone's battery life - this is because the phone would only need to transmit in a low-power standard such as Bluetooth in order to reach the device, which would then use its own battery (which would be continuously getting recharged, by walking) for the high-power long-range transmissions to the network. Krupenkin claims that this could allow phone batteries to last up to ten times longer than normal.
The U Wisconsin technology is currently in the process of being commercialized, through Krupenkin and Taylor's company, InStep NanoPower. If it does make it to the marketplace, it may have some competition - Dr. Ville Kaajakari is also developing a piezoelectric device for shoes, that generates power as its user walks.

Support Anna Hazare....



Support this 74 years one man army for his noble cause...
He is doing this for us, for our nation against corruption...
Join our hands to support him...
Jai Hindh!!!!!!


Those who dont knows what the jan lokpal made difference this time than its previous

The Jan Lokpal Bill (also referred to as the citizens' ombudsman bill) is a proposed anti-corruption law in India. It is designed to effectively deter corruption, redress grievances and protect whistle-blowers. If passed and made into law, the bill seeks to create an ombudsman called the Lokpal (translation: protector of the people) - an independent body similar to the Election Commission of India with the power to investigate politicians and bureaucrats without prior government permission. First introduced in 1969, the bill has failed to become law for nearly over four decades.



Difference between Draft Lokpal Bill 2010 and Jan Lokpal Bill
Draft Lokpal Bill (2010)Jan Lokpal Bill (Citizen's Ombudsman Bill)
Lokpal does not have powers to investigate the prime minister.Lokpal will have the powers to investigate the prime minister.
Lokpal can only probe complaints approved by the Speaker of theLok Sabha or the Chairman of the Rajya Sabha.Lokpal will have powers to initiate suo moto action or receive complaints of corruption from any citizen if it deems it worthy.
Lokpal will only be an Advisory Body with a role limited to forwarding reports to a "Competent Authority".Lokpal will have the power to initiate prosecution of anyone found guilty.
Lokpal will have no police powers and no ability to register a First Information Report or proceed with criminal investigations.Lokpal will have police powers as well as the ability to register FIRs.
The CBI and Lokpal will be unconnected.Lokpal and the anti corruption wing of the CBI will be one independent body.
Punishment for corruption will be a minimum of 6 months and a maximum of up to 7 years.Punishments will be a minimum of 10 years and a maximum of up to life imprisonment.

Chinmayi breaks new ground, launches iOS app

Chinmayi
Popular singer, dubbing artist and entrepreneur, Chinmayi has become the first Indian singer to have an exclusive Chinmayi app on iOS devices such as iPhone and iPad. So far, music directors like G V Prakash have an official app on Apple Store; however only iPhone users can download the app. An Andriod app is soon in offing and Chinmayi stated, “My app will have exclusive content and music that we are working on.” Daksha LLC, a US based company formed by Naveen Varadarajan, has developed this app. Naveen has revealed that within a few hours of this app’s launch users from France, Italy and China apart from India, US and Dubai have downloaded the app.
Chinmayi, recently, won the 2010 Nandi Award for Best Female Dubbing artist. She won this award for dubbing for Samantha in Ye Maya Chesave and she had recently dubbed for Kajal Aggarwal in Dhada. She frequently collaborates with A R Rahman and has sung for films like Robo (Kilimanjaro), Ye Maya Chesave (Manasa) and Mani Rathnam’s Kannathil Mutthamittal (Amrutha in Telugu). Great going Chinmayi.

Google Prius




Driverless cars. These specially designed Toyota Priuses are the same as the regular Prius (full hybrid electric mid-size car) with the addition of cylinder-shaped sensor (the vehicles eye) attached to the roof. Using artificial-intelligence software that can sense anything near the car it mimics the decisions made by a human driver.
The aim is not only to create more efficient and environmentally-friendly cars but also to help prevent traffic accidents, free-up people’s time and eventually reduce car usage.
Seven of these robot-cars have already been tried and tested, and drove more than 140,000 miles with very little human control. These hybrids are not yet for sale and for now, only accessible to its employees.

Google TV


GoogleTV now comes standard on the majority of Sony televisions but starting this year, it’s also going open source (much like the Android platform) to allow developers to create apps. A great way to create a community around the product and ensure fresh features are added on a regular basis, Google TV is yet another one of Google’s innovative products changing the nature of entertainment as we know it.
Incorporating social media, personalization, e-commerce, music and photo viewing, you can do everything you’re accustomed to doing online and even use your Android phone or iPhone as a remote control.
