Now, charge your cellphones with puddle of water


  • Any convenient water can be harvested for power, from a kitchen faucet through to a puddle in the jungle.
  • Researchers in Sweden have developed a new technique where you can charge your devices anywhere without electricity, provided there is a water source nearby.The new device leverages the team's more than 15 years of research on micro fuel cell technology and small flat Proton Exchange Membrane fuel cells at the Department of Applied Electrochemistry at KTH.
  • To use the PowerTrekk charger, you fill-up water compartment with about one tablespoon, close the lid and connect it to the electronic device with a USB cable.
  • It starts charging automatically as the water inside interacts with a small disposable metal disc causing hydrogen gas to be released.
  • When the gas combines with oxygen it converts chemical energy into electrical energy.
  • While in many ways fuel cells are similar to batteries, they are different in that electrodes do not become consumed making them finite.
  • Instead provided water and air is provided to the electrodes, these fuel cells will run.Very green power, water vapour is the only by-product.Currently, Powertrekk works with devices like cell and smartphones, digital cameras, ipods and GPS.
  • The company is looking into developing their fuel cells to function for larger devices like laptops

BlackBerry announces cheaper data plan for Rs 129



BlackBerry today launched a new data plan for subscribers in India that will offer 1GB of 2G data for Rs 129. Earlier, BlackBerry users had to shell out Rs 299 for just BBM and email access and a minimum of Rs 599 for Internet browsing as well.The new plan is available in 15 circles with Aircel, Idea Cellular and Vodafone. The list of circles include West Bengal (excluding Kolkata), Assam, Bihar, Haryana, Himachal Pradesh, Jammu & Kashmir, Kerala, Madhya Pradesh), North East, Orissa, Punjab, Rajasthan, Tamil Nadu (excluding Chennai), Uttar Pradesh West and Uttar Pradesh East.
Vodafone recently announced an Internet trial plan that offered 500MB of data for Rs 49 for 3G and Rs 25 for 2G access. However, that plan was valid for one-time use only.

Mobile devices that can change shape to be unveiled today

The devices could lay down the foundation for creating high shape resolution devices of the future.

Researchers including one of an Indian origin have developed prototype mobile devices that can change shape on-demand, and will be unveiled on Monday, the 29th of April.
The devices could lay down the foundation for creating high shape resolution devices of the future.
The research paper, to be presented at one of the world's most important conferences on human-computer interfaces, will introduce the term 'shape resolution' and its ten features, to describe the resolution of an interactive device: in addition to display and touch resolution.

One example of a device is the team's concept of Morphees, self-actuated flexible mobile devices that can change shape on-demand to better fit the many services they are likely to support.
The team believe Morphees will be the next generation of mobile devices, where users can download applications that embed a dedicated form factor, for instance the "stress ball app" that collapses the device in on itself or the "game app" that makes it adopt a console-like shape.In the future the team hope to build higher shape resolution Morphees by investigating the flexibility of materials.
They are also interested in exploring other kinds of deformations that the prototypes did not explore, such as porosity and stretchability.
