CHAMPAIGN, Ill. — Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye.

Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

Led by William P. King, the Bliss Professor of mechanical science and engineering, the researchers published their results in the April 16 issue of Nature Communications.

Big data is poised to transform society, from how we diagnose illness to how we educate children, even making it possible for a car to drive itself. Information is emerging as a new economic input, a vital resource. Companies, governments, and even individuals will be measuring and optimizing everything possible.

blogs.scientificamerican.com - April 18th, 2013 - Ramez Naam

As part one of this series showed, we are up against incredible challenges: feeding a world with a rapidly growing appetite, the continuing loss of the world’s precious forests, the ongoing collapse of fish species in the oceans, the rapid depletion of our fresh water resources, and the over-arching threat of climate change, which makes all others far worse.

Ending growth isn’t a realistic option.  Billions of people in the developing world want access to more resources, deserve those resources as much as those of us in the rich world do, and need them in order to rise out of poverty.

The Limits of the Earth, Part 1: Problems

blogs.scientificamerican.com - April 17th, 2013 - Ramez Naam

The world is facing incredibly serious natural resource and environmental challenges: Climate change, fresh water depletion, ocean over-fishing, deforestation, air and water pollution, the struggle to feed a planet of billions.

All of these challenges are exacerbated by ever rising demand – over the next 40 years estimates are that demand for fresh water will rise 50%, demand for food will rise 70%, and demand for energy will nearly double – all in the same period that we need to tackle climate change, depletion of rivers and aquifers, and deforestation.

One view of these looming threats is that we’ve exhausted planet’s resources.

Sonaar Luthra: Meet the Water Canary

submitted by D. Ofelia Mangen

ted.com - January 2012

After a crisis, how can we tell if water is safe to drink? Current tests are slow and complex, and the delay can be deadly, as in the cholera outbreak after Haiti's earthquake in 2010. TED Fellow Sonaar Luthra previews his design for a simple tool that quickly tests water for safety -- the Water Canary.

Geofeedia has created a group of algorithms that can search multiple social media sources by geography in real time.

“You just type in a place name, address and zip code (to find a Tweet, video or image),” CEO Phil Harris told the Chicago Sun Times.

Harris started and financed the company with chief operating officer Mike Mulroy and chief technology officer Scott Mitchell.

Stop Talking About the Weather and Do Something: Three Ways to Finance Sustainable Cities

Submitted by Albert Gomez

hbswk.hbs.edu - November 6th, 2012

The wrath of Hurricane Sandy has illuminated a fundamental question: How do we ensure that our cities are resilient in the face of inevitable future disasters? A destroyed city is not a sustainable city. I'm making the case that it's time to stop complaining about climate change.

Turning Rural Indians Into Water Entrepreneurs

fastcoexist.com - November 1st, 2012 - Whitney Pastorek

In Sanskrit, jal is the root for “water,” and sarva is the root for “everyone.” Put them together, and you’ve got exactly what Sarvajal delivers: Water for all. Originally launched as a nonprofit experiment in 2007, the company has grown into a thriving hub-and-spoke model of over 150 Sarvajal franchisees operating small reverse-osmosis filtration plants and revolutionary Water ATMs in India’s northwestern states, and its potent combination of entrepreneurship, common sense, and tech savvy has made a significant change in the quality of life for thousands of rural Indian villagers. “In 60 years of existence, India has always had getting clean water to people as the last mile at the top of its list of things to do,” says Sarvajal CEO Anand Shah. “We figured that if you put a lot of smart people on this idea, maybe you could come up with a solution.”

Missing Voices: How Can We Get More ‘Doers’ to the Social Innovation Table?

submitted by Albert Gomez

http://csi.gsb.stanford.edu - October 1st, 2012 - Kriss Deiglmeier

A number of reports have crossed my desk recently about how to accelerate and advance social innovation. There are reports on collective impact, convenings on impact investing, and conferences about measuring outcomes to name just a few. 

These gatherings and reports come from credible sources, and so their recommendations influence the agendas of leaders, funders, and investors.
