Found this video through Mixx. Wally Wallington demonstrates how the stones of Stonehenge could have been transported and erected with fewer people than you might think. He stands a 19,000 lb. block on its end by himself using only leverage and gravity.

Found this story on Digg. I like the 1000′+ outdoor elevator, it is much more impressive than the Grand Canyon Skywalk. If only it weren’t in China.
The only thing that might top this is the Millau Bridge.

I recently bought a Garmin eTrex Vista Cx and like every new toy, I’ve got to play with it until something breaks. Until then, I’ll squeeze in some useful work. Using Robogeo to geocode the location info onto my photos, I’ve assembled a quick and dirty Google Map page. Most of these are just some shots taken from the car at various intersections to see if the location is close enough for more detailed uses.
Here’s some thumbnails of the pics I took. They link to the originals, which are rather large, especially the photostitched ones.
