China Criticizes US For Making Weapon Plans Steal-able, Alleges Attacks From US
Etherwalk writes "Huang Chengqing, China's top internet security official, alleged that cyberattacks on China from people in the U.S. are as serious as those from China on the U.S. 'We have mountains of data, if we wanted to accuse the U.S., but it's not helpful in solving the problem.' Huang, however, does not necessarily attribute them to the U.S. government just because they came from U.S. soil, and he thinks Washington should extend the same courtesy. 'They advocated cases that they never let us know about. Some cases can be addressed if they had talked to us, why not let us know? It is not a constructive train of thought to solve problems.' In response to the recent theft of U.S. military designs, he replied with an observation whose obviousness is worthy of Captain Hammer: 'Even following the general principle of secret-keeping, it should not have been linked to the Internet.'" A few experts think China's more cooperative attitude has come about precisely because the U.S. government has gone public with hacking allegations. -
Another Step Forward In Small Scale Electrical Generators
NicknamesAreStupid writes "Product Design & Development reports another breakthrough in small scale solid oxide fuel cells. This methane-fueled cell achieves about 50% efficiency at around 2kW, enough to power an average home. It does so by efficiently recycling its heat to perpetuate the process. Of course, this is not practical for most homes, which only have natural gas that contains nearly one fifth impurities. However, that could change if gas suppliers refined their product." -
Alternative Energy Policies a Boon For Inflatable Electric Car
Brian Stretch writes with a story about the Mini Utility Vehicle prototype from XP Vehicles, an electric car that is partly inflatable. The recent struggles of the auto industry and a political climate that supports the development of alternative energy vehicles have given the car a better chance at actually hitting the market. Quoting: "Building a car takes many years and tens to hundreds of millions of dollars traditionally. XP is able to cut a lot of the costs and timeframe because its car has 70 percent less parts than a regular car, and the company is using novel materials that require simpler factory devices, and production and manufacturing processes that lower the cost to deploy. ... The seat is inflatable, the dashboard is inflatable, and the internal structure and carrying racks are inflatable, or a mesh suspension. Instead of requiring six-axis robots, XP uses radio frequency welders that look like giant waffle irons. The factory equipment is much less expensive and the car simply has less parts that could fail. The motors are built into the rear wheels in most XP prototypes. The first cars to reach the market will have two rear hub motors and a motor controller, that's it."
