How to: make a carbon-negative fuel
LinkMy colleague Jer Faludi has written up the best overview I've yet read about how biochar/gasification systems work. Given that there is at least the theoretical potential here to create a carbon-negative energy source (that is, an energy source that over the course of normal operation actually *removes* carbon dioxide from the atmosphere), the char/gas combo has a lot of people, um, fired up.
(Though it's important to remember that when dealing with complex systems like climate, topsoil and farm subsidies, no bullet is as silver as it looks from afar.)
Snip:
"We've mentioned terra preta before: it's a human-made soil or fertilizer. "Three times richer in nitrogen and phosphorous, and twenty times the carbon of normal soils, terra preta is the legacy of ancient Amazonians who predate Western civilization." Although we don't know how it was made back then, we do know how to make it now: burn biomass (preferably agricultural waste) in a special way that pyrolisizes it, breaking down long hydrocarbon chains like cellulose into shorter, simpler molecules. These simpler molecules are more easily broken down by microbes and plants as food, and bond more easily with key nutrients like nitrogen and phosphorus. This is what makes terra preta such good fertilizer. Because terra preta locks so much carbon in the soil, it's also a form of carbon sequestration that doesn't involve bizarre heroics like pumping CO2 down old mine shafts."
This prototype of an Acme semi-portable notebook with a huge folding three-way display was rolled out in Taipei during Taitronix Autumn 2007 that just wrapped up earlier this week. It starts out as a mild-mannered suitcase, and then unfolds into a monster laptop with a outlandishly wide screen. There is no information on the size of each of the flat panels, but from what we can see they look like they are each at least 20-inch-diagonal displays. No pricing was announced, but it'll be available sometime next year. [
AT&T, the 800-pound gorilla of U.S mobile services, decided to 
In the case of this Oppo PMP, the moniker "Super" certainly applies. The Super Five can handle just about any format you can throw at it including: RM, RMVB, FLV, DAT, MPG, MPEG, AVI, 3GP in video and OGG, MP3, WMA and WAV and dual-APE, FLAC Lossless audio. Plus, photos in JPEG, BMP, GIF and PNG pose no problem for this little feature packed device. Speaking of small, all of that functionality is crammed into a credit card sized 2GB flash memory player that features a 3-inch color screen with QVGA resolution. Naturally, something this cool isn't going to be found anywhere outside of China, bu if you can make the trip it will only run you $120. Sounds like a steal, but fear not because Oppo has 
The folks from Skydeck just received a written notice from Verizon Wireless for an opt-out system for sharing your call records to third-party advertisers. Unless you call them and opt-out, Verizon will sell what numbers you called, how often you called, and your call length with "authorized companies," which includes their "affiliates, agents, and parent companies." Although it doesn't include your own name, number or address, something like this should be opt-in, not opt-out. If you're a Verizon customer, call 1-800-333-9956 and tell them you want to opt-out. Why should you let Verizon get even richer off your data for nothing in return? [
