We're not kidding. Salmon DNA gets spun into nanofibers and is used to coat these extra-durable white LEDs. They can even tune the color.
The United Nations Climate Change Secretariat (UNFCCC) has teamed up with several Googlers to put greenhouse gas emissions data on maps.
For something to be green, it has to be practical. That's not the case for this Kodak solar charger that takes 28 hours of sunlight to fully charge batteries.
Computer models are used for all kinds of things these days, including to help salmon safely pass hydropower dams to go breed upriver. Pretty cool what technology can do!
