Thanksgiving Vacation
This will be the last new posting until Monday, November 28. My family and I will be celebrating Thanksgiving with friends in the Southwest.

Today I ran across an article that describes a new technique for storing hydrogen at roughly room temperature and normal pressure. Practical storage is the sine qua non of a potential hydrogen economy, so anything that shows promise in this area is good news for hydrogen in general. In particular, I'm no fan of high-pressure storage on vehicles, no matter how well-designed the container. Nature abhors a vacuum, and to a gas at 10,000 psi, everything around it is a vacuum. In a future blog I will go into more detail on the other promising alternatives of the moment, including metal hydrides and nanotubes.

Before signing off the for the week, here are links to some past blogs that you might find interesting, if you didn't see them the first time around. (you'll have to scroll down in the linked monthly archive to the date indicated):

The oil markets have done their job:
Have We Really Forgotten? (August 9)

Climate change as a business risk:
What Can We Agree On? (July 27)

Hybrids may be a US and Japanese phenomenon:
Where Are the European Hybrid Cars? (June 28)

Has our air gotten cleaner or dirtier?
Clean Air (April 21)

This also seems like a good time to solicit your ideas about pertinent topics for the future. As this blog nears its first anniversary, what have I neglected to discuss, or what I have spent too much time covering? You can provide this feedback either by clicking on the "comments" link below this posting, or by email

Have an enjoyable Thanksgiving!
