Technology Review: Computer Clusters That Heat Houses
IBM has developed an "on-chip water-cooling system" that allows high-performance computer clusters to heat buildings and provide hot water. The technology also addresses data center energy use (currently very high) because it cools the computers themselves, while providing energy for other uses. Looks like a perfect win-win.
Big screens go green: NYC screen to be powered by renewables, but could go dark on rainy nights | RUDI - Resource for Urban Design Information
Description of $3m billboard in Times Square/ NYC, to be powered by wind & solar energy, at a savings of $12-15K per month. This is one of those big, wrap-the-building electronic billboards that resembles a giant TV screen.
QUOTE
Fitted with 16 wind turbines and 64 solar panels, the sign will be a first for Times Square.
(...)
By generating its own electricity — enough to light six homes for a year — the sign could save as much as $12,000 to $15,000 per month, according to Ricoh, which estimated that the sign would prevent 18 tons of carbon from being spewed into the air yearly.
The 'passive' sign is not studded with light-emitting diodes like so many others in Times Square, but will be lighted by 16 300-watt floodlights. It will feature custom-printed opaque vinyl sheeting bearing the red-and-white Ricoh logo. The sign will be green, nevertheless, a message 'to customers, other companies and the world that resources and energy can be used creatively,' Mr. Potesky said. 'The point is that there are ways of being environmentally friendly to the planet, even on a billboard.'

A New Twist on Hydropower - MIT Technology Review
Fascinating report on how a new mechanical device, which "mimics how fish harness energy from water flow," could contribute to the sustainable energy toolkit.
(Since the device is based on mimicking how fish do it, I'm adding the "biomimicry" tag to this article.)

Laser Sensors for Wind Turbines (MIT Technology Review)
"A new fiber-optic laser system can measure wind speed and direction up to 1000 meters in front of a wind turbine, giving the massive machines enough precious seconds to proactively adapt to gusts and sudden changes in wind direction. The device, developed by Catch the Wind, a startup based in Manassas, VA, could improve the efficiency of wind turbines and keep them from breaking down. "

Technology breakthrough with big implications for energy-use in hotter climates: a new valve that cuts air conditioners' energy use by 25%. MEMS = microelectromechanical systems.
Sun + Water = Fuel (MIT Technology Review)
Fascinating article about Daniel Nocera's work on biomimical process similar to photosynthesis, except in this case it's sunlight turning water into hydrogen. If the process can scale, it has revolutionary implications for energy supplies.
The House That Twitters Its Energy Use, by Katie Fehrenbach « Earth2Tech
Among other things: "The Twitter stream is an exercise in using the data from home automation feeds, and the hope is that, by making energy usage data transparent and easy to digest, it will change consumer behavior and reduce energy consumption." As I noted in bookmarking the related Wired Magazine piece, this relates to Wired Mag's earlier article on "Peak Water," too, where we learn that many London homes don't even have water meters. Actually, it's the same here in Victoria & Oak Bay. Not good.
Home Tweet Home: Energy-Savvy House Broadcasts on Twitter | Wired Science from Wired.com
Wired Magazine article by Alexis Madrigal on "wired" homes, including http://twitter.com/andy_house, by IBM "master inventor" Andry Stanford-Clark who "rigged up his home to twitter its energy use." See The House That Twitters Its Energy Use by Katie Fehrenbacher (http://earth2tech.com/2008/04/30/the-house-that-twitters-its-energy-use/).
Compare to Wired Mag's recent "Peak Water" article, which pointed out that many London households aren't even on water meters, making consumption monitoring impossible.
In addition, consider too the New Scientist article, "City road networks grow like biological systems" (4/23/08).
All this relates to infrastructure -- and to how we're just beginning to understand it from new angles. (See also Doc Searls' continuing investigation of infrastructure in Linux Journal.)

This revolution is being led by infotech guys like the Google engineer we wrote about, or the creator of the Twitter system, Andy Stanford-Clark, who works for IBM's Pervasive and Advanced Messaging Technologies team. And as Katie Fehrenbacher noted over at Earth2Tech, the creators of Flash are now hard at work on an energy monitoring and automation system called Greenbox.

Why daylight saving time is bad for the environment (Toronto Star)
"The annual time change has long been sold as a way to save energy, but the opposite might be true." I wouldn't mind if we stayed on one time all year round, although I admit liking daylight savings for the longer evenings. But then I don't live in an area that uses air conditioning -- the main reason why electricity use goes way up in DST and therefore there's a net increase in fuel / energy consumption (vs any sort of energy saving).
I dislike changing from standard time to daylight saving time and vice versa, the silly business of spring forward or falling back -- it feels like jet lag without any of the benefits of actual travel.
-
Always sold as a conservation measure, the practice of daylight savings actually jacked electricity use in homes across one central U.S. state by up to four per cent, according to a new American study.
-
Instead of saving electricity and money by adding an extra hour of sunlight to evenings most of the year, it cost Indiana homes an extra $8.6 million in electricity bills – mostly from chugging air conditioners – each year. And since 95 per cent of that extra energy was generated by coal-fired power plants, that meant much more atmosphere-warming carbon dioxide was spewed into the air.
Expanded nationally, those results would translate to at least two coal-fired electricity plants pumping power just to feed the daylight savings habit.
"In Indiana, I can tell you unambiguously now, there are social and environmental costs associated with daylight savings time because of the pollution emissions and carbon dioxide emissions contributing to climate change," Kotchen says.

An Oil Quandary: Costly Fuel Means Costly Calories - New York Times
NYT article on the problems around "the other oil crisis," triggered not in small measure by our (West's) desire to circumvent fossil fuel dependence by relying on biofuels.
CCA - Canadian Centre for Architecture
-
This major exhibition is the first to study the architectural innovation spurred by the 1973 oil crisis, when the value of oil increased exponentially
and triggered economic, political, and social upheaval across the world. Featuring over 350 objects including architectural drawings, photographs, books
and pamphlets, archival television footage, and historical artefacts, the exhibition maps the global response to the shortage and its relevance to architecture today. -
Sparked by the combination of reduced oil production and drastically increased prices, the oil crisis marked the end of a period of constant growth in Western
countries following the Second World War. Along with social and economic adjustments such as energy-saving measures and reduced activity came the understanding
that unlimited development based on unrestricted oil at low prices was no longer feasible. Taking its title from familiar signs at gas stations throughout
North America during those years, 1973: Sorry, Out of Gas investigates how architecture and urbanism responded to this new reality. In contrast to
the era’s sense of austerity it was a time of significant developments and intense experimentation in the field of architecture.The research and innovations of thirty years ago are of particular relevance in the context of contemporary concerns about diminishing energy resources.
While influential at the time, much of the innovative work of architects, engineers, and activist groups of the period was forgotten once financial markets
and energy distribution systems adjusted, and political focus diminished. Today, however, a new sense of urgency is emerging, provoked by the reality of
a deteriorating environment and a finite supply of fossil fuels. “It is of vital importance to consider the radical yet, in many cases, little-known work
from the 1970s as architects today struggle to address similar issues,” said CCA Director and exhibition curator Mirko Zardini. “By providing insight on
the forerunners of many contemporary approaches to sustainable living, the exhibition aims to increase public awareness and encourage contemporary research
in the field.” - 9 more annotations...

Canadian Prime Minister Pierre Trudeau is seen in a televised address to the country assuring us that voluntary measures would be enough for the Great White North. His excuses for not going further were Canada's harsh winters and great distances. Three decades later, we rank among the worst per capita polluters on the planet. But don't blame Canadians – geography made us do it.
Crosscut Seattle - Green is the new gold rush? Not without government R&D
-
He reframed the discussion about coping with global warming by saying it was a golden opportunity to make money. One week earlier, Seattle business leaders were hearing the same siren song at the Chamber of Commerce retreat in Vancouver. A bank president declared, "Green is the new gold."

One big factor that this rosy scenario leaves out is the role of government. Here, the seminal thinkers are Ted Nordhaus and Michael Shellenberger, authors of a new book, Break Through: From the Death of Environmentalism to the Politics of Possibility. The authors argue against the high-regulation model for battling pollution and other environmental woes, or approaches that raise the cost of dirty energy. You can read about the controversy they have stirred up with greens in this essay.
