How fast can a robot move?
Could robots beat us at computer games? If we are referring to the robots that is only capable of slow movements like the Asimo made by Honda, then we can be sure that it can’t compete in computer games. And the same goes for those robots used at industrial sites. However, a team from Ishikawa Komuro laboratory at the University of Tokyo has succeeded in designing a robot that is not only fast, but dexterous as well. What the future beholds is any body’s guise. Take a look at this video……

The life saving water desalination million dollar question
A team of researchers from MIT and Korea has developed a new self-contained and driven by gravity water desalination system that can help in disaster stricken area. All that you have to do is to just pour salt water (provided it is available) from the top of the device and clean water will pour from the bottom. How nice? Not only that, it is powered by solar power and will filter out contaminants, viruses and bacteria as well. Just the device for disaster regions.
The new system separates salts and microbes from the water by electrostatic-ally repelling them from the ion-selective membrane in the system. Unlike normal membrane technology, there is no need to force water out through a membrane, so there is no need for a large power pulse. Another plus is that there won’t be any fouling after a period of use. The new device looked more like a micro chip piece and the water separation works on a micro basis. In order to filter a sizeable amount of water, an array of the micro devices will have to be connected together. An 8-inch-diameter wafer - could output 15L of water per hour.
