An artificial leaf converts water and light to oxygen, and that's good news for road-tripping to places beyond Earth.
One of the persistent challenges of manned space exploration is that pesky lack of oxygen throughout much of the universe. Here on Earth, trees and other plant life do us a real solid by taking in our bad breath and changing it back to clean, sweet O2.
So what if we could take those biological oxygen factories into space with us, but without all the land, sun, water, soil, and gravity that forests tend to require? This is the point where NASA and Elon Musk should probably start paying attention.
Royal College of Art graduate Julian Melchiorri has created the first man-made, biologically functional leaf that takes in carbon dioxide, water, and light and releases oxygen. The leaf consists of chloroplasts -- the part of a plant cell where photosynthesis happens -- suspended in body made of silk protein.
"This material has an amazing property of stabilizing (the chloroplast) organelles," Melchiorri says in the video below. "As an outcome I have the first photosynthetic material that is living and breathing as a leaf does."
In addition to its potential value to space travel, Melchiorri also imagines the technology literally providing a breath of fresh air to indoor and outdoor spaces here on Earth. The facades of buildings and lampshades could be made to exhale fresh air with just a thin coating of the leaf material.
But perhaps best of all, a man-made breathing leaf could be the key to not just space travel but space colonization. No need to figure out how to till that dry, red Martian dirt to get some nice leafy trees to grow; we could just slap them on the inside of the colony's dome and puff away.
If all energy production channels were employed, the United States has sufficient resources to eliminate all coal, gasoline and diesel combustion in all demand sectors and replace them with natural gas, wind and solar electricity firmed and shaped with both grid-scale and distributed energy storage.
...it’s good news that a first of its kind assessment of community-led marine conservation in the Western Indian Ocean adds to growing evidence that marine conservation works best when local communities are responsible for fisheries management.
George Ingram examines the key elements of the New Deal, an accord between the g7+ and donor countries that creates a framework for how those countries can move from fragility to sustainable development.
Over coming months, we’re breaking down the building blocks of a Bicycle Friendly Community, and the first step is a solid legal foundation. While we’ve made many gains over the years, there are still plenty of examples “legal impediments” to bicycling. Last week, we looked at those impediments in more detail. Today, I’m looking at the oppostie: the city ordinances that improve or promote bicycling, which is a good marker for a Bicycle Friendly Community.
One easily visible example is a bicycle parking ordinance like the one in Santa Monica, Calif., which not only ensures an adequate supply of racks at destinations, but also requires event organizers to have monitored bicycle parking for 200 – 250 bikes if attendance is expected to reach 1,000 or more (requiring 3 attendants).
Better yet, the Santa Monica Bike Center, a non-profit and League Platinum Bicycle Friendly Business, is often contracted to provide this service, and the funds raised subsidize and expand the Center’s educational programs. When other event participants come to realize how much easier it is to arrive by bike (and have free parking valet service!) the word spreads and events become bicycle attractors rather than a frustrating cause of increased congestion.
While poverty increased and spread in the 2000s, it also became more concentrated in high-poverty and economically distressed neighborhoods, and those neighborhoods were increasingly located in the suburbs. By 2008-2012, the suburbs accounted for 40 percent of residents living in such areas in the nation’s 100 largest metro areas. Elizabeth Kneebone explains why this increased concentration of poverty in suburban communities can pose greater challenges.
It’s hot in Bakersfield, California, especially during the summer months when temperatures regularly hit 110 degrees. But as The Hampton Inn & Suites Bakersfield North-Airport is discovering, the sun also has its advantages for reducing utility costs and increasing customer acquisit

I had the good fortune to meet Arjun Makhijani who has long advocated the "solarization" of parking lots. Perhaps a business opportunity presents itself. Solar panels not only providing power for operations and energy to the grid, but charging all those Teslas and other electric vehicles that will be hitting the road soon.....
If you have not read Makhijani's book, Carbon-free and Nuclear-free published by IEER Press, now might be a good time to look.
For humans to be sustainable, we need a world filled with more people who are creative, visual, passionate, broadly curious, generalists, integrators, listeners, systems thinkers and doers, and people who know how to create lives filled with both success and purpose

As a change management leader I think the program described in this article is a good amalgam of left and right brain "training."
The Massachusetts solar renewable energy credit (SREC) market is undoubtedly one the most complex incentive programs. Among its complexities is the annual clearinghouse auction mechanism, which allows SREC sellers the opportunity to auction their SRECs at the end of each summer for a fixed price of
