Energy efficiency might not always be the highest priority for the military, but after hearing about how the Army spends more on air conditioning in Iraq and Afghanistan than NASA's entire budget, we think they should give it a second look. And they are, with a new generation of gas-electric hybrid tanks.
The only eco-friendly source of "base power," that is, power that (unlike solar or wind) is available at a constant rate whenever you need it, is geothermal. This lack of reliability makes green power a hard sell, and the Oak Ridge National Laboratory might have an answer: seawater.
Sad news for everyone who has ever wanted to drive a car shaped like a sperm down the highway: Aptera, who has been working on an ultra-efficient, ultra-futuristic space fighter on wheels, has run out of both time and money.
Scotland, being awesome, is putting some serious effort into eventually sourcing 100% of its energy from renewable sources. Seeing as the weather up there is often blustery enough to blow your kilt up around your ears, wind energy seems like a safe enough bet, and the Scots are getting a giant new wind turbine that comes with its own helipad.
We all take electricity for granted. We're doing it right now, as I'm typing this on my computer and you're reading it on yours. But forget about electricity; much of the developing world doesn't even have a reliable source of light after sunset. The LuminAID could help change that.
Dreaming of a "white Christmas" is so 20th Century. Welcome to the 21st Century, where we think of the holiday season as green — and we don't mean cash. Today, with so many stresses on our environment and the need to be mindful consumers, many people are looking for that special "green" gift that will keep on giving. Never fear — we've scoured the web for the grooviest gifts that embody all kinds of green giving. Whether upcycled products bringing something old back to life, something made from left over materials or something that simply brings a bit of nature back into our increasingly urban lives we think all these gifts are wicked cool.
Odds are, if you're reading this, you're already part of a modern civilization. But what if the Earth got hit by a giant comet and we all needed to start from scratch? Most of us wouldn't have a clue what to do, but this open source project aims to provide start-up civilizations with everything they need to make a self-sufficient jump into modernity.
Dean Kamen, noted brilliant and sometimes crazy inventor, has patented a new design for inflatable wind turbines which can double as illuminated advertising billboards. I guess free wind energy is just not quite good enough.
See that swimsuit? Study it closely. No, keep looking. Okay, now, notice anything weird about it? If you said "well gee it kinda looks compostable," you're much better at observing the finer points of swimsuit technology than I am, because guess what, you're right: it is compostable. And so is the skimpier version.
In what can't possibly fail to be a symbolic gesture, old coal mines in Germany are being repurposed into giant storage tanks for wind energy.
