Tidal Power

Excellent post by Roland Piquepaille on a test project being installed in New York’s East River. If successful the pilot project by Verdant Power will become the first installation to generate electrical power using tidal ebb and flow. Reading his article, I was struck by the possibility of using this tidal technology in other places, specifically rivers. Turns out the Tennessee Valley Authority already approached the company about supplying low impact hydroelectric power in the TVA.

Uh-oh, this makes me nervous.

The Basics of Space Flight

Orbital period of a satelliteAnother great link from the Astronomy Picture of the Day:

Here’s a very cool lesson plan from JPL, used to bring new employees up to speed on the Basics of Space Flight. “Basics of Space Flight is a training module designed primarily to help JPL operations people identify the range of concepts associated with deep space missions, and grasp the relationships these concepts exhibit. It also enjoys popularity among high school and college students, as well as faculty, and people everywhere who are interested in interplanetary space flight.” It explains in lucid terms on JPL designs flight paths, orbits, and how they use gravitational boosts from various planets to slingshot probes to the furthest reaches of the solar system.

Anthropology Days at the 1904 Olympics

Since everyone seems to have Olympic fever these days, I thought it might be worthwhile presenting an article on 1904 Olympics and the ‘Anthropology Days’ that preceded the games during the 1904 World’s Fair in St. Louis. The fair organized a series of games to see whether the savages brought from around the world displayed any athletic ability. Ainu vs. Zulu, Sioux vs. Bedouin, Patagonians against Philippine Igarot tribesmen. The dismal results were loudly proclaimed as evidence of their inferiority. Lovely, just lovely. Makes me proud to be a native St. Louisan.

What's for dinner?While I’m at it, let’s settle this legend that Dogtown got it’s name from Igarot tribesmen poaching all the dogs from the area during the fair. It’s nonsense, an urban legend that has become popular in the last few years. My parents never heard of such a thing, and they’ve lived in St. Louis all their lives. I mentioned it to both of them during my recent visit and they looked at me like I was crazy. Don’t know how this one got started, but it needs to be discredited.
