Pebbles to Hydrogen

China’s growth demands a lot of energy and they are aggressively pursuing nuclear options. On the one hand traditional reactors such as have not been built in the US since 1979 and which make many nervous. On the other hand they are working on pebble-bed reactors:

A reactor small enough to be assembled from mass-produced parts and cheap enough for customers without billion-dollar bank accounts. A reactor whose safety is a matter of physics, not operator skill or reinforced concrete. And, for a bona fide fairy-tale ending, the pot of gold at the end of the rainbow is labeled hydrogen.
Small currently is in the 200 Megawatt range and cheap means approximately $300 million. These small reactors can be combined in a modular fashion using common monitoring and control systems. This seems promising simply from the perspective of power generation but there is more.
Apparently this reactor techcnology has promise for hydrogen production:
To power a billion cars, there’s no practical alternative to hydrogen. But it will take huge quantities of energy to extract hydrogen from water and hydrocarbons, and the best ways scientists have found to do that require high temperatures, up to 1,000 degrees Celsius. In other words, there’s another way of looking at INET’s high-temperature reactor and its potential offspring: They’re hydrogen machines.
…Researchers at Sandia National Laboratories believe efficiency could top 60 percent – twice that of low-temperature methods. INET plans to begin researching hydrogen production by 2006.
In that way, China’s nuclear renaissance could feed the hydrogen revolution, enabling the country to leapfrog the fossil-fueled West into a new age of clean energy. Why worry about foreign fuel supplies when you can have safe nukes rolling off your own assembly lines? Why invoke costly international antipollution protocols when you can have motor vehicles that spout only water vapor from their tail pipes? Why debate least-bad alternatives when you have the political and economic muscle to engineer the dream?
Now this looks like a line of research I’d be putting a lot of money into if I were promising the citizens of my country a reduced reliance on foreign oil.
Update (9/9): An alert reader notes in the comments that the DOE has identified a similar reactor type as part of its technology evaluation roadmap. It is not, though, clear from the referenced document what level of funding the US has provided for this effort.


Using Coral to Link Large Files

Keywords has created a handy tool for those of you that might want to link large files:

I’ve created a handy bookmarklet you can use to instantly get the Coral version of a link. This should allow even the smallest of web content publishers to post large movies, graphics, etc. and not worry about their webserver going down due to excessive traffic.

A Real Home Internet Service?

One may be just around the corner for some of you. Verizon will be offering a new internet service in a few geographic areas beginning later this summer:

A 2mbps to 5mbps Fios connection will cost $35 a month if purchased along with Verizon’s local and long-distance telephone service. The service will cost $40 if purchased alone. A connection of up to 15mbps is available for $45 a month if purchased as part of the same telephone service bundle, or $50 alone. The company did not reveal pricing for the 30mbps plans.
Heck, I pay nearly $50/month now for Comcast 3 Mbps service. It will be great if Verizon is able to agressively roll this out in many markets as it will put price/performance pressure on the cable companies and help drive skinny band DSL to it demise.


Science Fiction Museum and Hall of Fame

Tegan is a charter member of the Science Fiction Museum and Hall of Fame which is opening this week. She attended the “Gala premier opening” and has written a preview for us. A couple of snippets:

Ok, overall first impressions: Crowded, but not too crowded. Literally every time you turned around, there was something new to look at. I was suffering from “oooooh! Shiny thing!” syndrome, big-time.
…..
Disappointments. Not many… There was as strong a focus on books and magazines as on TV and movies, but comic books were underrepresented.
…..
And the Experience Music Project building is still the ugliest building in Seattle, even if what’s inside it is pretty cool.

A lot of folks consider this building ugly and it certainly does wrench at one’s sense of what is right when you look at it. As time goes by, though, I’ve found it to be much more interesting then just another box and I suspect that much of the inside ambience is due to the external shell creating internal spaces with interesting curved shapes.
Hey, sorry to digress. Go read the rest of Tegan’s review.
