Over the last month Carbon-Nation went quiet as its editor made noise elsewhere on the web. He should have kept you linked in. Bad editor! Here’s what you missed:
“Cheap Cashmere Sweaters”: A Connect the Dots photo feature on MSN Green tracking cashmere’s environmental footprints –carbon and otherwise– back to the desertified steppes of Central Asia. Bottom line message: The price of that cashmere sweater looks good now, but the cost to the environment will bite you in the end.
Two for IEEE Spectrum Online:
“Power Transmission Without the Power Electronics”: During their low-resolution beginnings digital music and photography delivered a jarring rendition of sounds and images. Today, digital devices used to control electricity flows are making a similar mess on power grids.
“Electric-Car Maker Touts 10-Minute Fill-Up”: Altair Nanotechnologies’ lithium ion batteries for electric vehicles charge up fast. Very fast. One of its 35 kilowatt-hour packs, capable of propelling an EV pickup truck for 160 kilometers, can fully charge in just 10 minutes-a feat that would be downright dangerous with most lithium batteries. But will such rapid-charging prove practical on the street?
And a troika for MIT’s Technology Review website:
“Prospecting for Power”: The ultra-sensitive detection of traces of helium rising from the Earth’s mantle may hold the key to sniffing out sites of hidden geothermal energy.
“Cleaner Nuclear Power?”: Senators representing several Western states are promoting thorium. They say it’s a cleaner-burning fuel for nuclear-power plants, with the potential to cut high-level nuclear-waste volumes in half. Some nuclear watchdogs agree.
“Carbon Capture Moves Ahead”: Carbon offsets marketer Blue Source is building the business case for carbon-capture and storage systems by storing CO2 in oil wells.
