TGV gets even faster (and maybe comes to California)

Oh, can we please order about a dozen of these?

A French high-speed train, with a souped-up engine and wheels, breaks the world speed record near Grigny, eastern France, Tuesday, April 3, 2007, reaching 574.8 kph (357.2 mph). The black and chrome train with three double-decker cars, named the V150, bettered the previous record of 515.3 (320.2 mph), set in 1990 by the French fast train. However, it fell short of the ultimate record set by Japan’s non-conventional magnetically levitated train, which sped to 581 kph (361 mph) in 2003.

More at the Houston Chronicle.  To save you the math, 350 mph gets one from San Diego to San Francisco in an hour and a half, an order of magnitude faster than Amtrak currently manages.   And that’s not just wishful thinking, either:

Hours before the run, Transport Minister Dominique Perben received a delegation from California, which is studying prospects for a high-speed line from Sacramento to San Diego, via San Francisco and Los Angeles.

There’s still a long way to go, but perhaps by the time Ben wants to explore California on his own, he’ll be able to go by (really fast) train.

a tale told by a chicken, full of sound and fury

So you may have wondered why I’m so busy at work these days. Well, here’s the deal:

Eventful, Inc., the leading global events service, announced today that it would cease the operation of its popular Web site Eventful.com on May 1st in favor of next-generation interface Twitter, provided by Obvious Corporation of San Francisco. Twitter is a service which allows users to get instant update messages (“tweets”) from friends via SMS, instant messenger, Web, or by way of a number of custom desktop clients.

Once the commitment was made, it was surprisingly quick work to adapt the Eventful API to the new platform. Development of the Twitter-based service, dubbed Eventful Chicken, took just over a week to reach the public beta stage, including event search, recommendations, watchlists, reminders, and Eventful Demand (renamed “I wish they’d come here”). The service can be previewed currently at http://twitter.com/echicken.

There’s more, but you get the idea. Take a look and let me know what you think. I’m too tired to comment intelligently.

SpaceNet, the interplanetary supply chain

I’m sure this will come in handy someday soon.  MIT researchers have created SpaceNet, a software tool for modeling interplanetary supply chains.

“Increasingly, there is a realization that crewed space missions such as the International Space Station or the buildup of a lunar outpost should not be treated as isolated missions, but rather as an integrated supply chain,” said [MIT researcher Olivier L.] de Weck.

While “supply chain” usually refers to the flow of goods and materials in and out of manufacturing facilities, distribution centers and retail stores, de Weck said that a well-designed interplanetary supply chain would operate on much the same principles, with certain complicating factors. Transportation delays could be significant–as much as six to nine months in the case of Mars–and shipping capacity will be very limited.

I can’t wait for the day when I can order spare parts online and have them delivered to my house on Mars.

Congratulations, SpaceX!

SpaceX, which I’ve covered previously, successfully launched its Falcon 1 rocket yesterday.  The launch wasn’t without incident — there was a problem with the second stage after launch, and the first launch attempt was aborted at the last second — but the results were deemed enough to justify launching commercial payloads later this year.

On the latest flight, the second stage did not achieve its full speed, again because of an early shut down of the engine, this time because the vehicle began an unexpected roll.

Mr Musk said he thought this problem should be easy to fix once flight engineers had analysed the data.

“The launch was not perfect, but certainly pretty good,” he added.

“Given that the primary objectives were demonstrating responsive launch and gathering test data in advance of our first operational satellite launch later this year, the outcome was great.”

I personally see this as a huge success, because they were able to launch, reach space, and test their operational capacity.  Besides all that, they were able to make fundamental improvements to their launch platform in a single year, while still targeting that $7-million-per-launch figure.  Congratulations, SpaceX, and we can’t wait for the next stages!

I’m going to MIT

…well, to their OpenCourseWare site, at least.  According to a recent article in Information World Review:

The entire catalogue of information from 1,800 courses at the prestigious Massachusetts Institute of Technology (MIT) will be available free online by the end of the year. Once uploaded, it will represent one of the internet’s most important resources.

Seriously, though, this is quite a boon.  The site contains syllabi, lecture notes, assignments, reading lists, and sometimes even videos of lectures.  It doesn’t mean that students in Kansas can get an MIT education from a computer, but it does mean that teachers in Kenya can teach using an MIT-level curriculum and materials.

MIT started the site in 2001 as a pilot program, but at the time all the talk was about how to charge students for distance learning and restrict materials to those who paid.  Now the materials are being licensed under Creative Commons, and MIT is presenting them as a gift to be shared instead of a revenue source.

Now to find a few month-long chunks of free time in which to actually use these gifts…
