  1. Syringe disposal solution in a soda can from Little Devices that Could

    Syringe disposal solution in a soda can

    This design called Antivirus was the winner of the People’s Choice Award at this year’s Index Awards.

    The designer of Antivirus – a cap to protect was inspired by her own experience as a young girl in a Singaporean refugee camp, where she received a vaccination with an infectious needle, making her sick for a long time.

    The cap is mounted on readily available beverage cans for segregation and isolation of used needles which are secured inside the permanently sealed can, preventing re-use of needles. The design embodies an element of sustainability in that it uses a waste product available even in low income countries.

  2. Potato Chip Ingredient Provides Longevity Boost to Concrete from Treehugger

    Who would’ve thought that the flavoring that helps give “salt & vinegar” chips their tasty tang could also help protect concrete from water damage? A new study by Awni Al-Otoom and his colleagues in Jordan has revealed that sodium acetate — a chemical commonly used in flavored chips (and a variety of other products and processes) — can work as a cheap and effective concrete sealant by providing a waterproof coating.

  3. Subway Sunlight Project from Inhabitat

    Sunlight transport systems are an Inhabitat favorite, as they make it possible to channel actual natural light into dark places and cast it through a fixture. The Subway Light Project is the first we’ve seen that incorporates sunlight transfer in public urban art, to save the city money on energy, and infuse public space with a good mood boost. Parsons student Caroline Pham, who designed the Subway Light Project, won first place in the school’s 2007 Sustainable Design Review. Her concept uses sunlight capture devices and fiber optics cables to channel sunlight into the enclosed corridors of the subway.

  4. Made From Scrap from Laughing Squid

    Made From Scrap is an emerging socially responsible company created around artists, instructors, and students, those who want to learn, investigate, tinker, recycle, teach, meet, and have fun.

    Our goal is to inspire and foster the Bay Area’s growing community of resourceful do-it-yourselfers, crafters, and artists. Our focus is recycling and how it can be more than throwing something into a blue bin. In our imaginations, it’s dynamic, immeasurable, sustainable, and a catalyst for developing community.

  5. Metal Casting from MAKE

    Pretty pics

  6. Watercone – An Ingenious Way To Turn Salt Water Into Fresh Water from The Sietch

    The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun. The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use.

  7. Used Computer’s Parts from

    Instead of throwing old non-working mouse or keyboard, these guys from TechWeb built cool sculptures of buildings, planes and toys.

  8. Do SUNSLATES Answer NIMBYs? from Jetson Green

    Solar Shingles for folks who think panels are ugly.

  9. A solar refrigerator for developing world from CNET

    The Solar Turbine Group [in Cambridge, MA] is trying to bring refrigeration to emerging nations by harnessing the power of the sun.

    The organization, which consists largely of MIT alumni, has devised a solar thermal generator that can be brought to market for $12,000 or less. A typical system can generate 600 watts of electricity or 20 kilowatts of energy for heating and cooling, according to Sam White, director for STG. The same system can also produce both at the same time, albeit less of each.

    A good chunk of the systems are made of easily available car parts and plumbing supplies. STG currently have project sites at Bethel High-School and the village of Ha Teboho in Lesotho
