Solar Sponge Efficiently Makes Steam :
Generating steam is enormously useful. Much of the world’s energy actually comes from steam—coal power plants heat up water to produce water vapor, which turns turbines to generate electricity. A new technology creates steam by harnessing solar energy, using a relatively cheap sponge-like material, and it does it with greater efficiency that ever previously achieved, according to a study published in the journal Nature Communications.
The researchers don’t claim the device could be used to create electricity, at least not yet. But it could relatively easily be scaled up to make fresh water out of salt water via distillation, for example, or to sterilize medical or food-processing equipment in areas of the world where electricity is hard to come by, said MIT researcher Hadi Ghasemi in a statement.

Creative Carbon Scotland offers tools like the Green Arts Portal, an online system available for creative organizations to track their carbon footprint, as well as the Green Arts Initiative, a simple sustainability accreditation system provided to companies, offices, individuals and venues operating within the cultural sector.
The organization also hosts workshops, provides advice, and has a firm commitment to furthering research in the field of arts sustainability.
For this year’s Edinburgh Art Festival, Creative Carbon Scotland will be monitoring the carbon implications of the festival’s major exhibition Where do I end and you begin. … Data will be collected on the logistics of exhibition production, such as the travel and transportation of artworks and people, as well as the materials and energy used in the installation and running of the exhibition.

Bringing a twist to the idea of a bag for life, the RNLI has made a messenger bag out of decommissioned life jackets. The RNLI work tirelessly around the country saving the lives of those who get in trouble at sea, and summer is one of their most busy periods.
All the life jackets used have been worn by the brave volunteers at the RNLI during real sea rescues.

This is a really thoughtful and engaging piece by Jenna Wortham:
By some measures, we are witnessing a rapid change in computing and the swift evolution of relationships between humans and automated helpers. A vision of the future is materializing before our very eyes, the development of networked helper bots that will manage every aspect of our lives, automating it and, theoretically, improving it by simplifying it.
But what happens when those devices go into disrepair — or worse, obsolescence — and their sleeker, faster successors go on sale, as part of the relentless cycle common among most major hardware companies?
Is smart garbage the next booming category of electronic waste?

Waste. What is the value of waste? In Cape Town everything is re-used and re-used and re-used until it falls apart. In Cape Town nothing is waste. Everywhere, from townships to more well–to-do areas, we can find products made of used or re-used materials. ….
Department of Design is a three weeks event, initiated by the Dutch consulate, with Christine de Baan as program director. What makes this official Dutch participation in Cape Town Design Capital 2014 so special, is that it is not a ‘business as usual’ presentation of design objects. But this initiative rather seeks collaboration with South Africa on topics such as energy, water, health, education and town planning.

A supermarket chain in the UK announced today that it’s going to power one of its stores entirely off food waste. It’s an attractive solution to two of the most gnawing sustainability concerns: waste and energy.
A Sainsbury’s in Cannock, a town in the West Midlands, will get all of its electricity from food waste through a process called anaerobic digestion. The process is pretty much what it sounds like: waste food is “digested” by microorganisms in huge tankers sealed off from the air, which Sainsbury’s compares to a human stomach.
Biffa, the waste management company working with the supermarket, explains that the waste is broken down into a slurry that degrades into an energy rich biogas, a mixture of methane and carbon dioxide.
