Vegetarians use more water
The Los Angeles Times has the best tool that I've yet seen for understanding the amount of water used in agriculture.  It lets you put together various proteins, starches, vegetables, and drinks to make a typical dinner, and shows you how much water it take...

I just found Wayne Hale's blog .  Be careful reading this thing, I just lost nearly an entire night of sleep.  The latest update, which covers the launch of STS-93 , is just breathtaking. Here's a video which documents the folks at mission control scramblin...

The Skybox camera
Christmas (and Christmas shopping) is upon us, and I have a big review coming up, but I just can't help myself... SkySat-1, from a local startup Skybox Imaging, was launched on November 21 on a Russian Dnepr rocket, along with 31 other microsatellites and a...

Hyperloop Traffic
This is a huge post, about a subject that may not be terribly interesting. I suspect most of you will want to skim all but the first section, and come back later when I refer to this post from later posts.  The big picture I have looked at the California H...
