From Inhabitat:

Just yesterday San Francisco saw the unveiling of the world’s first algae fuel-powered vehicle, dubbed the Algaeus. The plug-in hybrid car, which is a Prius tricked out with a nickel metal hydride battery and a plug, runs on green crude from Sapphire Energy — no modifications to the gasoline engine necessary. The set-up is so effective, according to FUEL producer Rebecca Harrell, that the Algaeus can run on approximately 25 gallonsfrom coast to coast!

Of course, if you read the fine print you find that it’s only running on a 5% algae mixture so I’m not sure if this is much more than a PR stunt for Sapphire Energy, but it’s interesting anyway.  It’s also a little disingenuous to claim the car will be run coast-to-coast on 25 gallons; I’m fairly certain that’s assuming it will be plugged into the electrical grid every day.

There’s a surreal set of photographs at the library of congress taken by Sergei Mikhailovich Prokudin-Gorskii of various scenes in Russia, mostly around the turn of the century. This was long before color photographic paper was developed, and the images were taken using multiple exposures and color filters. The finished work was projected through color filters again to reconstruct the original image. The picture above has the following description:

The Solovetskii Monastery, founded in the early fifteenth century on an island in the White Sea in the far north of European Russia, was for centuries one of the most important monastic and cultural institutions in Russia. The thick walls shown in this photo protected the monastery from foreign invaders on several occasions. The monastery was partially destroyed in the early Soviet period and became the site of the first major concentration camp of the Gulag system. In the post-Soviet era it was returned to the Orthodox Church and is once again a functioning monastery.

Some more interesting shots:

One of the astronauts on the space station took this picture of a water droplet that escaped from his shower.  The drop is spinning along the axis shown, so the air bubbles in the water are being pushed away from the higher-density water at the surface.  It would be cool to watch a droplet of Sprite do this; the carbonation bubbles would spontaneously emerge from solution and migrate to the center, expanding the size of the droplet.  Here’s a similar phenomena: alka-seltzer in water:
