Olafur Eliasson on Little Sun

Little Sun is a lantern powered by the sun’s natural light designed to fight unequal energy distribution around the world. Part artwork, part social project tackling energy poverty, the bright yellow orb, complete with wavy rays radiating out from the center, looks remarkably like its namesake. Thanks to its small size, the functions are manifold: use it as anything from a table lamp to a bike light. The Little Sun website declares it “a work of art that works in life. It transforms the light that is for all of us into a light that is for each of us.”

Olafur Eliasson regards his Little Sun solar-powered light to be a work for art for a worldwide audience.
Little Sun is fairly resilient and can be expected to work for three years.
The flower-shaped Little Sun uses LED technology and captures sunlight through a 6 x 6 cm mono-crystalline solar module.
Little Sun was launched on May 11 at the World Economic Forum in Addis Ababa, Ethiopia.
After four hours of charging, Little Sun will work for five hours.
Small solar power generation can bring light to people who live off the grid.
Little Sun can be hung, used as a table lamp, or taken out to be used as a lantern or bicycle accessory.

Solar Cells and Other Fairy Tales

“Wind is renewable. Turbines are not.”

Solar Cells and Other Fairy Tales: Symbols and Expectations for a Clean Energy Future

This event was held at the Center for Science, Technology, Medicine & Society at the University of California, Berkeley.

“Solar Cells and Other Fairy Tales: Symbols and Expectations for a Clean Energy Future”

7 Mar 2012
12:00 PM – 1:30 PM

Ozzie Zehner
STSC Visiting Scholar

The seductive tales of wind turbines, solar cells, and biofuels foster the impression that with a few technical upgrades, we might just sustain our current energy trajectories without consequence. Media and political coverage lull us into dreams of a clean energy future juxtaposed against a tumultuous past characterized by evil oil companies and the associated energy woes they propagated. Like most fairy tales, this productivist parable contains a tiny bit of truth. And a whole lot of fantasy.

This talk does not expose a scandal or cover-up in the traditional sense, but rather explores a particular alignment of interests and priorities that presents equally provocative questions to the environmental community. Solar cells shine brightly within the idealism of textbooks and the glossy pages of environmental magazines, but real-world experiences reveal a scattered collection of side effects and limitations that rarely mature into attractive realities.

This talk is based on Ozzie’s forthcoming book, Green Illusions: The Dirty Secrets of Clean Energy and the Future of Environmentalism (University of Nebraska Press, June 2012).

Article: Going Green? The Dark Side to Solar Energy
“There’s little reason to believe that household photovoltaic arrays and wind turbines do much to help the environment … They are certainly touted as green, but because of their energy footprint of production, toxins, and numerous limitations, they often merely swap one set of side effects for another.”

Ozzie Zehner: Solar panels contain heavy metals that can leach into groundwater when disposed of. Right now, societies are not capable of being powered by alternative energy.
