Food, Fuel and Fools

Corn - food or fuel?
/. has an interesting article.

The US Dept. of Energy is stating that corn based fuel is not the answer. From the article, “I’m not going to predict what the price of corn is going to do, but I will tell you the future of biofuels is not based on corn,” U.S. Deputy Energy Secretary Clay Sell said in an interview. Output of U.S. ethanol, which is mostly made from corn, is expected to jump in 2007 from 5.6 billion gallons per year to 8 billion gpy, as nearly 80 bio-refineries sprout up.

What is so interesting about this is that this severely truth-challenged administration has issued an opinion which is harmonious with modern scientific and environmental thinking.

Meanwhile, The New York Times has an article today highlighting farmers’ intention to plant more corn this year than at any time since WWII, mostly to support ethanol production.

Then we have Fidel Castro lashing out yesterday in an editorial, his first since his surgery last July, blaming the US and it’s biofuel plans for exaserbating world hunger:

Castro said more than 3 billion people in the world were condemned to die prematurely of hunger or thirst from plans by his ideological foe, the United States, to convert foodstuffs like corn into fuel for cars.

Corn based ethanol is a losing proposition, as it yields little or no more energy than it takes to produce, as opposed to cellulostic sources, such as Bush’s famous switchgrass or sugar cane. Problem is that Iowa, with its first in the nation caucuses has managed to preserve the sanctity of ethanol for many years due to the quadrennial panderfest of Presidential politics.

So, be prepared to see the US maintain its fascination with corn-based biofules for the foreseeable future while other countries find true efficiencies in other materials, such as Brazil with sugar cane.

Epilog: By the close of trading corn futures had dropped by 5% and the stock of Archer Daniels Midland (the largest biofuels producer) had fallen.

Dogs in space

AstroNASA and DARPA have gotten together to test spacebound refueling and repairs using a pair of test satellites, ASTRO and NextSat:

Service via automaton

The $300 million Orbital Express vehicles come in two forms: the smaller target NextSat and the larger service spacecraft ASTRO.

Short for Autonomous Space Transport Robotic Operations, the ASTRO servicing satellite is a 2,100-pound (952-kilogram) vehicle laden with 300 pounds (136 kilograms) of hydrazine propellant and measuring about six feet (1.8 meters) tall and wide. Its robotic arm is designed to either latch onto NextSat and pull it close for a manual docking, or transfer replacement hardware, such as a battery, from ASTRO to the target vehicle.

Love those dancing robots

Um, Shouldn’t We Find Some Girls to Talk To?
Hipster #1 with thick-framed glasses: Yeah, he could do the robot [does crappy robot dance].
Hipster #2: You are so lame.
Hipster #1: No, it’s funny.
Hipster #2: It’s not realistic.
Hipster #1: It’s supposed to be how a robot would dance. What’s not realistic about it?
Hipster #2: Yeah, so a robot programmed well enough to have a dance function would do what you just did…
Hipster #1: Probably.
Hipster #2: If they were to program a robot human enough to have a dance function it would have to be incredibly advanced and I don’t think an incredibly advanced life-like robot would be programed with such stiff moves. They would almost certainly give him at least slightly groovier moves.
Hipster #1: I think you’re thinking of a super advanced robot. I mean, we’re just talking about, like, a robot that appears in the next decade.

SETI Finally Finds Something

Found on SlasSETI at Home screenshothdot:

“SETI@home is a distributed processing client from UC Berkeley that installs on the volunteers’ home computers and harnesses their processing power in the search for extraterrestrial intelligence. So far nothing noteworthy has comeout of this massive project… that is until today! One of the volunteers was able to track down his wife’s stolen laptop using the IP address that SETI@home client reports back to the server. After getting back the laptop his wife said, ‘I always knew that a geek would make a great husband.'” Link

There we have it: Women, if you’re reading this, geeks are good guys!
