The application describes how face-recognition webcams and CAPTCHAs can be used in schools to ensure that computer users are paying attention to ads, and the recourse of 'disabling or even repossessing the computer' if they are not."

Roland Piquepaille writes "According to Nature, a European-funded project has been launched to store electricity created from wind in refrigerated warehouses used to store food. As the production of wind energy is variable every day, it cannot easily be accommodated on the electrical grid. So the 'Night Wind' project wants to store wind energy produced at night in refrigerated warehouses and to release this energy during daytime peak hours. The first tests will be done in the Netherlands this year. And as the cold stores exist already, practically no extra cost should be incurred to store as much as 50,000 megawatt-hours of energy. Here are additional details and a picture illustrating this brilliant idea."

An anonymous reader writes with a story on CNet about two teens who were prosecuted under anti-child-porn laws in Florida for having made and emailed racy photos of each other. Both were under 18 years old, so the resulting pictures are clearly illegal; but the teens' intent was not to share the pictures with anyone else. An appeals court majority opinion found that emailing the photos from one of the kids to the other was a careless act that should, it seems, bring down the full weight of the law. A minority opinion argued that the laws were intended to protect children from exploitative adults, not from other children.
