Cows On Treadmills Produce Clean Power For Farms 640

separsons writes "William Taylor, a farmer in Northern Ireland, recently developed the Livestock Power Mill, a treadmill for cows. Taylor uses the device to generate clean, renewable power for his farm. Cows are locked into a pen on top of a non-powered, inclined belt. The cows' walking turns the belt, which spins a gearbox to drive a generator. One cow can produce about two kilowatts of electricity, enough energy to power four milking machines. It may seem like a kooky idea, but Taylor could be onto something: According to his calculations, if the world's 1.3 billion cattle used treadmills for eight hours a day, they could provide six percent of the world's power!"

Ham Radio Still Growing In the iStuff Age 368

vhfer writes "From NPR comes this story about old-school communications in the age of Twitter: 'Only a few years ago, blogs listed ham radio alongside 35 mm film and VHS tape as technologies slated to disappear. They were wrong. Nearly 700,000 Americans have ham radio licenses — up 60 percent from 1981, a generation ago. And the number is growing.' The article goes on to say that while there's plenty of 60-plus year old hams, there's also a growing contingent of teens. I just met a 14-year-old, licensed in 2009. Getting rid of the Morse Code requirement sure helped in that regard. So does the fact that the test questions (and the answers) are freely available, legally, on the Internet. Study, take the test, hang the license certificate on the wall. Your geek cred gets an immediate boost. And who knows? Maybe the next time there's a Haiti-earthquake-sized disaster, you'll be one of the thousands of ham volunteers who provided the only communications in/out of Haiti for weeks following the quake, not to mention all of the tactical comms the country had for nearly a month."

Stand and Deliver Teacher Jaime Escalante Dies 389

DesScorp writes "Jaime Escalante, the math teacher portrayed in the hit '80s movie Stand and Deliver, has died of cancer at age 79. Escalante is legendary for creating the advanced math 'pipeline' program at Garfield High in East Los Angeles in the '70s and '80s, an area populated mostly by poorer Hispanic families. Escalante's students eventually outpaced even richer schools in advanced placement tests for calculus. Escalante refused to accept excuses from his students or community about why they couldn't succeed, and demanded a standard of excellence from them, defying the notion that poor Hispanic kids just weren't capable of advanced work. While Escalante became a celebrity because of the hit movie about his efforts, jealousy from other teachers ... as well as red tape from teacher's unions and the public school bureaucracy, resulted in Escalante and his hand-picked teachers leaving Garfield. Since his departure, Garfield has never replicated Escalante's success with math students, and Reason Magazine reported on the shameful way in which others tore down what Escalante and his teachers worked so hard to build."

YouTube Is Down 152

A number of readers have noted that YouTube is currently giving back 400 and 502 http errors, and has apparently been doing so for an hour or more. I suggest you use this window of opportunity to get something done: the dancing kitties will still be there when you're done.

Neptune May Have Eaten a Planet and Stolen Its Moon 145

jitendraharlalka noted a piece about the origins of Neptune. There is a theory now that it once ate a super-earth in the outer solar system, and kept its moon as some sort of macabre trophy to make sure that Mars and Venus didn't get any big ideas.

Hotmailers Hawking Hoax Hunan Half-Offs 135

Frequent Slashdot contributor Bennett Haselton writes "An estimated 200,000 Hotmail users currently have their auto-reply set to a message spamming an advertisement for Chinese scam websites, which sell "discounted" electronics. Presumably the spammers compromised a large number of Hotmail accounts to pull this off, but wouldn't it be pretty easy for Hotmail to query for which users have that set as their auto-reply, and turn the auto-reply off for them?" Read below for Bennett's thoughts.

DOJ To Oversee Windows 7 Development 427

MrKaos writes "Windows 7 is already being reviewed by U.S. government technical appointees. Under the terms of Microsoft's November 2001 Justice Department settlement, and final court judgment issued about a year later, a government-sanctioned 'Technical Committee' has been formed to oversee Windows development. The TC is responsible for ensuring that Microsoft complies with the terms of the final judgment, investigating complaints about Microsoft abuses and regularly reporting on the company's compliance."
