The Rise of Small Nuclear Plants 490

ColdWetDog writes "The Oil Drum (one of the best sites to discuss the technical details of the Macondo Blowout) is typically focused on ramifications of petroleum use, and in particular the Peak Oil theory. They run short guest articles from time to time on various aspects of energy use and policies. Today they have an interesting article on small nuclear reactors with a refreshing amount of technical detail concerning their construction, use, and fueling. The author's major thesis: 'Pick up almost any book about nuclear energy and you will find that the prevailing wisdom is that nuclear plants must be very large in order to be competitive. This assumption is widely accepted, but, if its roots are understood, it can be effectively challenged. Recently, however, a growing body of plant designers, utility companies, government agencies, and financial players are recognizing that smaller plants can take advantage of greater opportunities to apply lessons learned, take advantage of the engineering and tooling savings possible with higher numbers of units, and better meet customer needs in terms of capacity additions and financing. The resulting systems are a welcome addition to the nuclear power plant menu, which has previously been limited to one size — extra large.'"

Submission + - Afghan Tech Minerals -- Cure, Curse, or Hype? (theoildrum.com)

Gooseygoose writes:

The Pentagon revealed last week that Afghanistan has as much as $1 trillion in mineral wealth, a potential game changer in the ongoing conflict there. Many news outlets have picked up this story, with some simply repeating the official talking points, while others raise serious concerns. Is this ‘discovery’ just hype, or will this truly alter the landscape of the Afghan war? Perhaps more importantly, can this mineral wealth (whether real or illusory) pave the way to a peaceful and prosperous Afghanistan, or is it more likely to drive geopolitical feedback loops that plunge the region further into turmoil? Below the fold is a quick look at the as-of-yet unasked questions about Afghanistan’s buried treasure.

The pressures and other difficulties under the water made this a logistic nightmare--it was unprecedented. Worse, it was a one-shot game--they screwed it up, this thing gushed until the pressure eased. The media's butchered this coverage too. Knowledgeable people (like those over at The Oil Drum) thought this was all about right. I'm not an expert on the matter, but I believe they've been planning the top kill since they realized that it was leaking. Thing is, getting all the equipment together to do something of this magnitude usually takes a few months, the fact that the got it all together in one month is pretty frakking impressive.

Pretty good stuff over at The Oil Drum on this...they just said they have two unconfirmed reports that cementing will start within hours on their twitter feed- http://twitter.com/theoildrum

Happy Towel Day 122

An anonymous reader writes "While Douglas Adams continues his attempt to set a new record for the longest extended lunch break, geeks all over the universe pay tribute to the beloved author by celebrating the tenth edition of Towel Day. Towel Day is more alive than ever. This year Richard Dawkins, one of Adams' best friends, has tweeted a Towel Day reminder to his numerous followers. The CERN Bulletin has published an article on Towel Day. There has been TV coverage and there will be a radio interview. The Military Republic of the Deltan Imperium, a newly formed micronation, has recognized Towel Day as an official holiday. In Hungary several hundreds of hitchhiker fans want to have a picnic together in a park. And there's a concert, a free downloadable nerdrap album, a free game being released, the list goes on and on."

Comment it's not about the size, it's about net energy... (Score 2, Informative) 720

The easy oil has been had, folks. It came out of the ground Beverly Hillbillies style. So, now we have to increasingly go deeper in the ocean or inject water into extant wells--and that gets expensive. Even the energy return on investment of oil has been declining (cite: http://netenergy.theoildrum.com/node/5600 ), and the energy return for alternatives is slowly improving, but is still 10 times less than that of light sweet crude--and because this is a liquid fuels/transportation problem, that means that economic growth can be curtailed unless we become more efficient AND use less.

(This is why I pay attention to the folks at The Oil Drum ( http://theoildrum.com/ ) and Energy Bulletin ( http://energybulletin.net/ ), they're well-intentioned academics/educators who are trying to get the world to live more smartly and sustainably...and the faster we do that, the better off we are going to be.)

YouTube for Science? 96

Shipud writes "The National Science Foundation, Public Library of Science and the San Diego Supercomputing Center have partnered to set up what can best be described as a "YouTube for scientists", SciVee". Scientists can upload their research papers, accompanied by a video where they describe the work in the form of a short lecture, accompanied by a presentation. The formulaic, technical style of scientific writing, the heavy jargonization and the need for careful elaboration often renders reading papers a laborious effort. SciVee's creators hope that that the appeal of a video or audio explanation of paper will make it easier for others to more quickly grasp the concepts of a paper and make it more digestible both to colleagues and to the general public."

Will Internet TV Crash the Internet? 267

Stony Stevenson writes "Analyst groups and Cisco have come out saying that the internet is heading for a crash unless it increases its bandwidth capabilities which are being strangled by the increased use of Web TV. Stan Schatt, research director at ABI said: "Uploading bandwidth is going to have to increase, and the cable providers are going to get killed on bandwidth as HD programming becomes more commonplace." He added that the solution to the problem is to change to digital switching and move to IPTV. "They will be brought kicking and screaming into the 21st century," he said. Cisco weighed into the argument, adding that it had found American video websites currently transmit more data per month than the entire amount of traffic sent over the internet in 2000."
