There's been a lot of press about Aquaponics and sustainable fish farming cropping up lately, so I wanted to share this astonishingly beautiful example: Sepp Holzer lives on a mountaintop in Austria, where he casually but thoughtfully manages a fish farm that provides all of his food, clean water, income, and electricity through nothing but a series of carefully placed pond systems. Gravity pulls the water from pond to pond, and little micro-organism-eating fish are gradually replaced by bigger and bigger predatory fish until he has clean water and full-sized trout! It's so simple it might seem like magic, but it's actually cooler than that. You can watch another short profile about Holzer's paradise here, and go here to see Eco Film's entire series on Permaculture....

This handsome devil is not a hazelnut bong. It's a nutcracker. Or rather, a nut-smashed-by-gravity's-pitiless-fury-er. Your wrists will thank you every bit as much as your legumes will fear you.

The Bad Astronomy blog posted this blink-and-you'll-miss it video of the International Space Station zipping across the face of the sun back in 2007. Let's put that speed in perspective: It orbits the Earth a mere 350 or so kilometers (220 miles) up; I like to say that if you live in DC and see it pass overhead, it's about the same distance from you as New York City. So it's actually pretty close to the Earth's surface, and screaming around at 8 km/sec (5 miles/sec). That's a good clip! From the point of view of someone watching from the ground, it only takes a couple of minutes for the station to go clear across the sky, horizon to horizon.
