It's called the Nano, for its high technology and small size. It's cute, compact, and contemporary. It's a complete four-door car with a 623-cc gas engine, gets 50 miles to the gallon, and seats up to five. It meets domestic emissions norms and will soon comply with European standards. It's 8% smaller in outer length than its closest rival, Suzuki's Maruti 800, but has 21% more volume inside. And at $2,500 before taxes (value-added taxes increase the price by about $300), it is the most inexpensive car in the world. Starting this fall, the Nano will roll off the assembly lines at a Tata Motors (TTM) plant in Singur, Bengal, and navigate India's potholed roads.

The Nano, also known as the People's Car, is Ratan Tata's dream come true, and is India's contribution to changing the global auto industry. "The car has put India on the global map," says Fionna Prims, head of business development for Segment Y, a Goa-based automotive consultant for emerging markets. "Tata has done in four years what the Japanese took 30 years to do. It will change the whole industry." Even rivals are gushing. "It's a red letter day for Indian industry, a day India should be proud of," says Venu Srinivasan, chairman of motorcycle maker TVS Motors. "Ratan Tata has the vision to create a new business model and all the naysayers are looking at it with concern. The Nano is a path breaker." ...   more »

Technology that allows consumers to respond to electricity price increases by cutting back on their usage in real time can lower customers' bills and create significant reductions in demand, a project spearheaded by the U.S. Department of Energy's Pacific Northwest National Laboratory has shown.

On average, consumers who participated in the project saved about 10% on their electricity bills and reduced peak power use by 15%.

The project, dubbed the Pacific Northwest GridWise Demonstration Project, involved two separate studies, both involving consumers in Washington and Oregon. In one study, called the Olympic Peninsula Project, 112 homeowners were given new electric meters, thermostats, water heaters and dryers that could be customized to a particular comfort level. -- Customers could set the devices on a spectrum ranging from complete comfort - meaning the desired temperature would be maintained regardless of the price of electricity - to complete economy. The devices were connected to IBM (IBM) software that automatically lowered the thermostats or shut off water heaters when electricity was most expensive, according to the limits set by the homeowners. ...   more »

Here's an interesting article re the OLPC (One Laptop Per Child) Project. I disagree with the article's conclusion (it omits the vast online support to be provided to olpc students), but I think it deserves further discussion here on SCIY. What do you think?

At the Consumer Electronic Show this week, the One Laptop Per Child foundation was supposed to make two announcements—the number of computers it sold under the Give One, Get One holiday program and a new olpc machine made jointly with Intel. But now Intel has pulled out or been pushed out of the project with olpc, depending on who you believe. It’s a mess and a mess of huge dimensions that encompasses a conversation of profit vs. nonprofit, nationalism vs. colonialism, technology vs. pedagogy, rote vs. experiential learning, Western design vs. Eastern design, good intentions vs. bad intentions. It doesn’t get bigger, or nastier. ...   more »

This recent report, from the session on 'Tipping Points' at the important Dec.07 American Geophysical Union meeting in San Francisco, illustrates the complexity of current technical discussions about the validity of the increasingly disruptive climate change scenarios being projected by various Climate Change computer models. The bottom line is that our models may be seriously underestimating the rapidly of the coming changes, as indicated in the previously posted article re the melting of arctic sea ice. ~rj

...In Hansen's talk, he did try to clarify what he meant by a tipping point. His notion of this has less to do with what mathematicians understand as "bifurcations," and more to do with a kind of inertia in the climate system. He means things like having passed a threshold of CO2 which, given warming in the pipeline and the lifetime of CO2, commits a certain discrete event — e.g. loss of perennial sea ice or the Amazon rainforest– to occurring even if we were to later reduce emissions to zero. He tried to distinguish between reversible and irreversible tipping points...

...where things get interesting is where you try to explain a magnitude of signal this big in terms of basic physics. This is important because there is a perception that GCM's vastly underestimate the amplitude of the response to total solar luminosity, leading to a perception that there is some "missing physics" (whether it be exotic amplification of a stratospheric response, or something like clouds and cosmic rays)...

But — the take-home point is that at this point the study of solar cycle response very strongly supports the notion that there is no need to invoke any mysterious or exotic missing physics (like cosmic ray modulation of clouds) in order to represent the response of climate to solar variability. If some models underestimate the response, this is likely to have more to do with errors in the vertical mixing of heat than any missing fundamental physics. ...   more »

Imagine a solar panel without the panel. Just a coating, thin as a layer of paint, that takes light and converts it to electricity. From there, you can picture roof shingles with solar cells built inside and window coatings that seem to suck power from the air. Consider solar-powered buildings stretching not just across sunny Southern California, but through China and India and Kenya as well, because even in those countries, going solar will be cheaper than burning coal. That’s the promise of thin-film solar cells: solar power that’s ubiquitous because it’s cheap... Silicon Valley–based Nanosolar [has] created the manufacturing technology that could make that promise a reality... With backing from Google’s founders and $20 million from the U.S. Department of Energy, Nanosolar’s first commercial cells rolled off the presses this year.

Traditional solar cells require silicon, and silicon is an expensive commodity... even the cheapest solar panels cost about $3 per watt of energy... To compete with coal, that figure has to shrink to just $1 per watt. Nanosolar’s cells use no silicon, and the company’s manufacturing process allows it to create cells that are as efficient as most commercial cells for as little as 30 cents a watt.

“You’re talking about printing rolls of the stuff—printing it on the roofs of 18-wheeler trailers, printing it on garages, printing it wherever you want it,” says Dan Kammen, founding director of the Renewable and Appropriate Energy Laboratory at the University of California at Berkeley. “It really is quite a big deal in terms of altering the way we think about solar and in inherently altering the economics of solar.” ...   more »

Entheogen: Awakening the Divine Within is a feature length documentary which invites the viewer to rediscover an enchanted cosmos in the modern world by awakening to the divine within. The film examines the re-emergence of archaic techniques of ecstasy in the modern world by weaving a synthesis of ecological and evolutionary awareness, electronic dance culture, and the current pharmacological re-evaluation of entheogenic compounds.

Within a narrative framework that imagines consciousness itself to be evolving, Entheogen documents the emergence of techno-shamanism in the post-modern world that frames the following questions: How can a renewal of ancient initiatory rites of passage alleviate our ecological crisis? What do trance dancing and festivals celebrating unbridled artistic expression speak to in our collective psyche? How do we re-invent ourselves in a disenchanted world from which God has long ago withdrawn? Entheogen invites the viewer to consider that the answers to these questions lie within the consciousness of each and every human being, and are accessible if only we give ourselves permission to awaken to the divine within. ...   more »
