writes "Back in 2010, the aid organization Climate Healers gave a number of solar powered cookstoves to rural Indian villages. They were rejected by the communities, mainly because they were useless when they were wanted most: for the evening meal sometimes after the sun goes down, and for breakfast before the sun has risen. Following this, the group issued a challenge to EngineeringForChange. Details of the challenge include the need to provide 1kW of heat at about 200C for two hours in both early morning and late evening, and they should be able to cook indoors, while sitting. A number of groups, mainly at U.S. and Indian engineering institutions, accepted the challenge, and developed potential solutions.
Now, almost a year later, the ten finalist designs have been selected. The actual papers have been posted to the E4C challenge workspace.
The goals of most of the designs are to keep the technology simple, although there are a few exceptions, and many include sand, oil, and salt based concentrated thermal storage. Many reports include some level of discussion on the social and economic considerations, barriers to acceptance and sustainability, and how to overcome initial resistance to adoption."Link to Original Source

The EFF and Carpathia Hosting announced this morning that they're working together to assist users who stored non-infringing files on Megaupload. Users can go to MegaRetrieval.comto connect with the EFF, which will review the cases and try to help resolve issues through their free legal services.“EFF is troubled that so many lawful users of Megaupload.com had their property taken from them without warning and that the government has taken no steps to help them,” said Julie Samuels, Staff Attorney at EFF. “We think it’s important that these users have their voices heard as this process moves forward.”"Link to Original Source
writes "A few weeks ago Google changed it's mobile site Root Certificate Authority. Unfortunately for a group of Verizon Wireless customers, their LG phones shipped with a preset list of a few trusted authorities, with no user certificate update capability. Verizon blames either Google for making a change or outdated phones for not supporting "changing security standards". Of course, Verizon Wireless is still selling some of the problem phones at its stores and website. Seeing as how Google tops the list of mobile web site visits, some users are upset at problem phones walling off part of the internet. Google blames Verizon, Verizon blames Google, customers are left piecing together conflicting customer service statements, all while their precious mobile Gmail is unavailable. It may be worth noting that users had a similar problem with Facebook in years past until the site implemented a less secure mobile login procedure for deficient devices."Link to Original Source
