America's First Eco-City: Doomed From the Start 258

Posted by Soulskill from the parking-spaces-not-big-enough-for-SUVs dept.
An anonymous reader writes "Despite backing from the Clinton Climate Initiative, and a $111 million investment from Subway Restaurant mogul Fred DeLuca, a planned city for Central Florida called 'Destiny' was doomed from the start, according to memos retrieved from Florida's Department of Community Affairs. According to state officials, despite a great deal of hype about Destiny, Florida, becoming the first fully sustainable city in the U.S., plans to build the city were rejected almost immediately due to concerns over 'possible urban sprawl, energy inefficient land use patterns, the endangerment of natural resources, and the undermining of agriculture.'"

New Thermocell Could Turn 'Waste Heat' Into Electricity 181

dryriver sends this quote from Phys.org: "Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity. A small team of Monash University researchers ... has developed an ionic liquid-based thermocell (abstract). Thermocell technology is based on harnessing the thermal energy from the difference in temperature between two surfaces and converting that energy into electricity. The new thermocell could be used to generate electricity from low grade steam in coal fired power stations at temperatures around 130C. This would be implemented by having the steam pass over the outer surface of the hot electrode to keep it hot while the other electrode is air or water cooled."

How To Compete With NSA By Hacking a Verizon Network Extender 56

New submitter Anita Hunt (lissnup) writes "This snooping hack-in-a-backpack could become a hot Summer accessory, since Reuters reported that 'researchers at iSec hacked into a Verizon network extender, which anyone can buy online, and turned it into a cell phone tower (video interview) small enough to fit inside a backpack capable of capturing and intercepting all calls, text messages and data sent by mobile devices within range.'"
