Microsoft will officially release Windows 8 to the public on Friday, and although company executives would never say so, they must be at least a little bit nervous about it. After all, the user interface (formerly known as Metro) is the most radical redesign of the operating system since Windows 95. The risk, of course, is that customers will respond with confusion, or worse: outright terror. The new Start screen looks entirely different from the traditional desktop (though that interface still exists), with floating, blocky tiles instead of files and folders. And it's almost entirely chrome-less -- even basic things like the battery indicator and clock are hidden from view until ...

London: A small British company has developed a way to create petrol from air and water, technology it hopes may one day contribute to large-scale production of green fuels. Engineers at Air Fuel Synthesis (AFS) in Teeside, northern England, say they have produced 5 litres of synthetic petrol over a period of three months. The technique involves extracting carbon dioxide from air and hydrogen from water, and combining them in a reactor with a catalyst to make methanol. The methanol is then converted into petrol. By using renewable energy to power the process, it is possible to create carbon-neutral fuel that can be used in an identical way to standard petrol, scientists behind the ...

Whenever a new technology is created that has the potential to offer more opportunity and freedom to the average human being, we must listen to the "concerns" generated by major industry and governments. With the Internet, we hear the propaganda that what we know to be a level playing field of the free market of ideas is perceived by those in power as a "potential terrorist recruiting source." In this way, there is a full spectrum of excuses that can be employed for overt suppression, or de facto suppression through regulation, which inevitably results in the hoarding of technology by corporations and governments.
