For the second time in two years a team from Germany has won the US Department of Energy's Solar Decathalon. This year's entry was a cube shaped house entirely covered in 300W and 70W solar panels generating a peak of 11.1kW. The DoE has published a complete product directory of all the subsystems and components used to build each house. Another notable design is the Canadian Team North house designed for optimal solar+insulation performance in high latitude climates.

According to an article posted in today's Wall Street Journal, the electricity grid in the U.S. has been compromised by foreign spies, leaving it vulnerable to disruption. Last year, the CIA acknowledged that the system had been compromised and that the goal had been extortion. In response, the Federal Electric Regulatory Commission issued new cybersecurity specs for the power grid, to which companies such as GE have begun responding. But could it be that the new security efforts are motivated by government officials who stand to gain by this attempt at drastically increasing government control over the Internet? [more inside]

A solar updraft tower generates electricity with nothing more than a greenhouse and a tall chimney. A 195 meter tall prototype in Spain cheaply operated at 50 kW for years. Now there are plans to build others, including a 40 MW tower, 750 meters tall (near twice as tall as the current tallest structure in the EU). Two others, a 200 MW tower in Australia (previously discussed) or a 400 MW tower in Namibia could become the tallest structure of any kind if built: 1km and 1.5km tall, respectively. Yet even those are dwarfed by the theoretical super chimney which could stand 5km tall and 1km wide. Such a tower would use the Earth's atmosphere itself as the greenhouse, could cause rain, reduce global warming and generate over 300,000 MW of "green" electricity. [more inside]

Virginity at age 22. Two approaches: 1. Sell it. "It became apparent to me that idealized virginity is just a tool to keep women in their place. But then I realized something else: if virginity is considered that valuable, what’s to stop me from benefiting from that?" 2. Keep it. "It is puzzling and disturbing to me that regnant feminism has never acknowledged the empowering value of virginity."

America has come a long way. There is the official version of history or the peoples' version. There are artifacts and rankings. They had some quirks and were occasionally men of their time. If you prefer audio or visual references those are available as well. Common knowledge has it that one GW was our first President but the title of first is under dispute. 230 years later another GW is making a run for worst. That is also under dispute by the nations best brains. For better and worse, the story of the Presidency is the story of America.

"Like the dotcom bubble, the disaster bubble is inflating in an ad-hoc and chaotic fashion." Journalist Naomi Klein discusses how corporations and governments are working together more closely than ever, using the mandate of catastrophe — whether natural or man-made — to further concentrate power in fewer hands, with less oversight: from illegal sales of American police technology to China to avert hypothetical tragedies during the Beijing Olympics, to the privatization of water supplies in post-tsunami Sri Lanka.

A positive energy building is one that produces more power than it consumes (yes they have been around for a while). The Masdar Headquarters in Abu Dhabi – due for completion in 2010 claims that it will be the first to do this on a substantial scale (mainly thanks to use of solar energy). David Fisher's spectacular “Dynamic Architecture” building in Dubai will aim to achieve the same goal using wind. Scaling up on the ambition stakes France has pledged all of its new housing will fit into this category by 2020.

Pond scum saves the planet? In the beginning, there were algae, but there was no oil. Then, from algae came oil. Now, the algae are still there, but oil is fast depleting. In future, there will be no oil, but there will still be algae. ^ Power your ride with pond scum. In some iterations you don't even need light. (we have talked about this before and the fact that CO2 powers the algae production is not insignificant) More details here.

Earth, 2100 AD. Atmospheric CO₂ has doubled to 1000 ppm. From shore to the horizon, there is but an unending purple color -- a vast, flat, oily purple. No fish break its surface, no birds. We are under a pale green sky, and it has the smell of death and poison. Paleontologist Peter Ward's new book links past mass extinctions to global warming and shows, absent major changes, "Our world is hurtling toward carbon dioxide levels not seen since 60 million years ago, right after a greenhouse extinction." Maybe it's time for a heresy: nuclear energy's green, and renewables aren't.

Following this 2005 post, this documentary on Osaka "Host Clubs", "The Great Happiness Space" [Google vid 1:15; misleading preview here] is like nothing I've ever seen. Dark and light and wrenching and weird and funny. And dark. Kafka comes to mind for a lot of viewers, but this would fail as fiction. A midpoint shift forces you to confront a reality that is staggeringly complex. It's a kaleidescope of self-awareness and -delusion; compassion and manipulation; candor and deception. Layered, nuanced, and self-referential. The chief host's blog translated somewhat idiosyncratically by google, gives you another perspective [note: not included in the spirit of "LOL Engrish"]. This insider's account of a hostess club, written by a Duke University sociologist, is a lot more predictable and straightforward.

The Tyranny of Structurelessness

[T]o strive for a structureless group is as useful, and as deceptive, as to aim at an “objective” news story, “value-free” social science, or a “free” economy. A “laissez faire” group is about as realistic as a “laissez faire” society; the idea becomes a smokescreen for the strong or the lucky to establish unquestioned hegemony over others. This hegemony can so easily be established because the idea of “structurelessness” does not prevent the formation of informal structures, only formal ones. . . . Thus structurelessness becomes a way of masking power, and within the women’s movement it is usually most strongly advocated by those who are the most powerful (whether they are conscious of their power or not).

Mike Strizki lives in the nation's first solar-hydrogen house. "The technology this civil engineer has been able to string together – solar panels, a hydrogen fuel cell, storage tanks, and a piece of equipment called an electrolyzer – provides electricity to his home year-round, even on the cloudiest of winter days. Mr. Strizki's monthly utility bill is zero – he's off the power grid – and his system creates no carbon-dioxide emissions. Neither does the fuel-cell car parked in his garage, which runs off the hydrogen his system creates."

Make that bribe a tax deduction The Australian Wheat Board (AWB) [previously] has been found by to have breached UN sanctions on Iraq by paying the former regime almost three hundred million Australian dollars (300,000,000.00 AUD = 235,733,088.15 USD) in illegal “kickbacks” (read bribes). While the Australian Navy was instrumental in enforcing sanctions, at a huge cost to the Australian people (and indeed a far greater cost to Iraq people) this company was doing all it could to prop up Sadam’s regime. Now in the Australian Taxation Office have ruled that the bribes aren’t bribes, and have allowed the AWB to claim them as a tax deduction. Happily for some AWB’s share price surged with the news, so that’s some good news at least. It looks as if US might be taking action.

Look at these red lips, these kohl lined eyes, this frank face full of mischief. These are Queens, Presidents, Prime Ministers, Heads of State, powerful government officials, CEO's and more. Just reading their bios tells you so much about who they are and what they believe in. Would a similar collection of 100 men offer as much to ponder over and respect?

[NSFW] Much of contemporary liberal thought rests on the idea of the Social Contract. In this scheme, we agree to give up a certain amount of freedom in exchange for the protection and opportunity that society provides. Our individual lives mirror this. We defer to others when politeness requires it. We assert ourselves and our needs with pleases and thank yous. Most of daily life has some power dynamic to it, expressed with the subtlety that civilization demands. And what is implicit in daily life is made explicit in the role-playing of BDSM, based on the idea of a Power Exchange, where one party explicitly agrees to give up a certain amount of power to another. For most people who are into this, the “scenes” are circumscribed by rules, usually discussed beforehand, such as appropriate safewords, time limits, etc. For a small subset of this group, the typical safeguards are cast aside and the slave surrenders all aspects of his or her life to the master. The female submissive Polly Peachum has written about this lifestyle in her essay “Violence in the Garden” about her life as a 24-7 slave and the sexual dimensions of that relationship.
