From their best case scenario, they can produce 25000 gallons per acre per year, which is 800 barrels a year. Current world oil consumption ~80,000,000 bbl/day * 365 = 29.2 billion barrels per year. 29.2 billion bbl per year / 800 bbl per acre per year = 36.5 million acres of this biofuel to fulfill the world's needs. 36.5 million acres / 640 acres per square mile = 57031 square miles. 57031 square miles is roughly the size of Iowa. US oil consumption is roughly 20,000,000 bbl/day, so that would be 14257 square miles set aside. Much more realistic - this is close to the area of Maryland. If oil gets super expensive again (>$120/bbl) and stays there, this could definitely become a reality.

Yellowstone Supervolcano Larger Than First Thought 451 451

drewtheman writes "New studies of the plumbing that feeds the Yellowstone supervolcano in Wyoming's Yellowstone National Park shows the plume and the magma chamber under the volcano are larger than first thought and contradicts claims that only shallow hot rock exists. University of Utah research professor of geophysics Robert Smith led four separate studies that verify a plume of hot and molten rock at least 410 miles deep that rises at an angle from the northwest."

My Halo 3 run incredibly faster now- although it isn't really mine. My Halo 3 disc got really scratched somehow, so I borrowed a friend's copy and installed it to my 360's HD. Now, with the image mounted up, load times are much faster, because it doesn't have to sort through scratched sections of the disc. Before, some levels weren't even playable, and now they are, all because I can install a game and only use the disc to prove I own the game. This feature will be very, very useful for people who have scratched discs who also have friends who can lend them a copy. Rip friends' disc -> play a previously unplayable disc.

Submission + - Terahertz: Riding the Wave of the Future

kirouac writes: "X-ray vision is yesterday's news. Terahertz technology is the wave of the future. Terahertz occupies space on the electromagnetic spectrum between microwaves and x-rays and that's where UNBC prof Matt Reid has focused his vision. He has just beaten a world record set in 1993, putting him in competition with researchers from MIT.

It was at the Advanced Laser Light Source facility in Montreal that UNBC's Matt Reid and his fellow researchers from UNBC, Alberta, Ontario, and Quebec used ultrafast lasers to produce bursts of terahertz waves with the largest energies ever. This achievement means they can see right through objects in real time. Terahertz waves have been the subject of research for about 20 years, but Dr. Reid's accomplishment opens up a whole new world for application of the technology."

Submission + - MS exec: Pirating software? Choose Microsoft

An anonymous reader writes: ArsTechnica is running a story regarding Microsoft's view that should software piracy occur, Microsoft's desire is that the pirated software be theirs, to potentially, in the future, convert users from the "dark side" into legit users who obtain licenses...

"At the Morgan Stanley Technology conference last week in San Francisco, Microsoft business group president Jeff Raikes commented on the benefits of software counterfeiting. 'If they're going to pirate somebody, we want it to be us rather than somebody else,' he said. 'We understand that in the long run the fundamental asset is the installed base of people who are using our products. What you hope to do over time is convert them to licensing the software.'"

Obviously Microsoft prefers the market to use their software even if it's pirated rather than the alternative to occur: the use of free software which threatens their dominance in the software market.
