I’m often on the lookout for healthy food that travels well, but I’m terrified of canned foods that contain the hormone-disrupting chemical bisphenol-A (BPA). Clearly, I’m not alone. The Environmental Working Group (EWG) has released a new report analyzing which brands are still lining their cans with BPA . While the FDA has failed to regulate BPA despite potential health risks associated with the chemical, including increased risk of brain and heart problems, as well as cancer, obesity and attention deficit disorder,  informed consumers are avoiding it. Between January and August last year, EWG surveyed 252 brands produced by 119 companies. They found only 31 brands, or 12 percent of all the brands they sampled, used BPA-free cans for all of their canned products and 34 brands used BPA-free cans for one or more of their canned products.

Click here to view the embedded video. What if you could power your iPhone from thin air? Making wires redundant was one of Nikola Tesla’s biggest dreams – a dream University of Washington researchers want to fulfill with PoWiFi. Shyam Gollakota and his team recently demonstrated technology at EmTech Digital in San Francisco that harvests ambient ‘backscatter’ radio signals to power battery-free temperature and camera sensors. The technology can also be used to charge nickel–metal hydride and lithium-ion coin-cell batteries at distances of up to 28 feet. In a recent paper describing their work, called Powering the Next Billion Devices with Wi-Fi , the researchers provide a detailed description of hey they successfully powered devices over WiFi using existing Wi-Fi chipsets–without reducing the router’s performance. Details after the jump.
