Sustainability Science
How might we keep the lights on, water flowing, and natural world vaguely intact? It starts with grabbing innovative ideas/examples to help kick down our limits and inspire a more sustainable world. We implement with rigorous science backed by hard data.

For the First Time, Researchers Make Plants That Glow Sustainably—And They Could One Day Light Up Our Homes

For the First Time, Researchers Make Plants That Glow Sustainably—And They Could One Day Light Up Our Homes | Sustainability Science | Scoop.it
Although glowing plants may seem like a work of science fiction, researchers have succeeded in creating plants that produce their own visible luminescence—and they say the possibilities for how we can use these plants are endless.

This week in Nature Biotechnology, the scientists revealed that bioluminescence found in some mushrooms is metabolically similar to the natural processes common among plants. By inserting DNA obtained from the mushroom, the scientists were able to create plants that glow much brighter than previously possible.

Jane Walkinshaw's curator insight, September 14, 2020 8:59 PM
I never even thought to have plants to light up our houses. That'd admittedly be super cool, even though they are created in a lab. I wonder how bright you could get them, realistically, and how they are able to "glow in the dark".

How can Atlanta get to 100% green?

How can Atlanta get to 100% green? | Sustainability Science | Scoop.it
More than 100 cities have pledged to run on 100% renewable energy and signed onto the Sierra Club’s “Ready for 100” campaign. But turning commitment into action is where the real work begins, and Atlanta might be the ultimate test case.
Omar Elizondo's curator insight, May 16, 2019 8:12 AM
Like any other city, Atlanta is woven with power lines, trams and buses. The electricity that makes Atlanta run comes mostly from coal, natural gas and nuclear energy. Only 6% to 8% comes from renewable sources.

Big Breakthrough for Big Rigs: The EPA’s New Fuel Economy Rule for Trucks - The Equation

Big Breakthrough for Big Rigs: The EPA’s New Fuel Economy Rule for Trucks - The Equation | Sustainability Science | Scoop.it
If you haven't yet heard, today the federal government issued a new rule to make sure that our nation's "heavy duty vehicles" (big rigs, delivery vans, garbage trucks, and the like) go almost 40 percent farther on a gallon of fuel. This new rule will reduce global warming emissions by 1.1 billion tons and oil use by 2 billion barrels over the lifetime of the program. This is the single most comprehensive set of fuel economy and global warming pollution standards for heavy duty vehicles ever put in place, and the United States now has the strongest truck fuel economy standards in the world.

Worldwide Country Comparison

Worldwide Country Comparison | Sustainability Science | Scoop.it

"MyLifeElsewhere allows you to compare your home country with different countries around the world. Ever wonder what your life would be like if you were born somewhere else?"

HG Académie de Rennes's curator insight, January 31, 2015 1:56 AM

Un site d'une grande simplicité d'utilisation bien qu'en anglais. Le principe est de choisir deux pays dans un menu déroulant pour en comparer les principaux indicateurs de développement sous la forme de petites infographies très pédagogiques.
La comparaison est évidemment un processus de raisonnement à mettre en place pour situer et caractériser en géographie. On songera ainsi à l'utilisation d'un tel outil dans le cadre de l'étude des inégalités de développement en classe de 5e et de Seconde, mais aussi pour une mise en perspective sur les Territoires dans la mondialisation en classe de 4e afin de caractériser un PMA, un pays émergent, un pays développé (cf. exemple réalisé pour l'illustration).

Dernière information sur ce site, les statistiques utilisées proviennent des bases de données open source de la CIA américaine.

Brian Wilk's curator insight, February 7, 2015 7:51 PM

After studying this comparison tool and using it to find the best of the best and worst of the worst, I picked out some highlights I'd like to share. Monaco is clearly the place to be born, earn, and live. When compared to the USA, the infant mortality rate is 71% less, the life expectancy is 10 years longer @ 84, and you'll earn 62% more money, no doubt because you have ten more years in which to do so. I believe the stats may be skewed a bit in this country comparison as the very rich live there and they have access to the best medical care, and probably don't have very many infants with them when they make the move from elsewhere, hence the low infant mortality rate. Austria is not a bad second choice as you are 33% less likely to be unemployed. On a sobering note, the life expectancy if you live in Namibia is only 52! Yikes, I'm already 53... It's far worse however in Swaziland. The life expectancy is sadly only 50.5 years and you are 44 times more likely to have AIDS than if you lived here. 26.5% of the population has AIDS! Be thankful for where you live and stop complaining, it's far worse on average in nearly all other countries.

Seth Dixon's insight:

Did you know that with 1/30th the territory of the United States, Norway still has over 25% more coastline?  I didn't either until I compared Norway to the United States using My Life Elsewhere.  This site is designed allow United States students to imagine how their lives might be different if they were born in a different part of the world.  Students would probably die 21 years earlier if they were born in Liberia and 11 times more likely to have died in infancy.   Students would be 43.8% less likely to grow up and be unemployed and have 36.3% less babies if they were born in Taiwan.  This side-by-side format is a great way to help students help make these statistics real and meaningful.  One major drawback: this site only allows users to compare a country to the United States.  If you prefer to have students compare, say Cuba to the United Arab Emirates, I would recommend that you try If It Where My Home.

Luci Solar Lights | The Portable Solar Lamps by MPOWERD | Sustainability Science | Scoop.it

Luci weighs only 4 ounces and collapses to one inch thin. Add a solar charged lithium ion battery and a 65 lumen light to the mix and you’ve got one impressive lady. Whether it’s for travel, disaster relief or anything in between, Luci always shines bright.

PIRatE Lab's insight:

My mom recently gave me one of these guys.  It seems pretty bright and the collapsable and waterproof nature makes it a natural fit for limited space (e.g. backpacking packs) or off-grid needs (e.g. first aid kits).

 

Nothing particularly revolutionary here, other than the fact this is a business trying to support the triple bottom line.

Coronavirus will realign investors’ priorities toward a new normal of sustainability

Coronavirus will realign investors’ priorities toward a new normal of sustainability | Sustainability Science | Scoop.it
It’s becoming clearer by the hour that the coronavirus pandemic represents an unprecedented global threat to both public health and global economies. The speed of the crisis and the change to our everyday existence, as well as the threat to our most vulnerable, is astonishing and has all of us reflecting on our values and investments.

But even in these dark early days, it’s possible to make out what could be a silver lining: The crisis points to the potential of a new normal that’s better for our climate future as investors reweight their portfolios in light of current events.

Helicopter engine manufacturer Safran studies hybrid power systems as a way to reduce turbine engine size and fuel burn.
PIRatE Lab's insight:
Hybrid engine technology has been poorly adopted in the aviation industry.  This has numerous reasons from needed high thrust demands to focus on aerodynamics of the outer shell of the craft, etc.  But there are increasing signs that some of the design innovations for terrestrial motors are being incorporated into the power plants for aerial craft.  This is but one example.

What ever happened to: "Small fridges make good cities"

What ever happened to: "Small fridges make good cities" | Sustainability Science | Scoop.it

In 2007, The Interior Design Show displayed what remains the most beautiful and well thought out kitchen I have ever seen, designed by Donald Chong, now with Williamson Chong architects in Toronto. Chong's thesis was that Small fridges make good cities- people who have them are out in their community every day buy what is seasonal and fresh, buy as much as they need, responding to the marketplace, the baker, vegetable store and neighbourhood vendor.

 

It was an idea whose time just hasn't come in North America.
