UH develops charcoal-fired fuel cell – The Honolulu Advertiser
The carbon cell functions something like a car battery. It has an anode and cathode positive- and negative-charged terminals in a liquid solution, and if you put an electrical load â€” like a light bulb â€” between them, electrical current flows from one to the other. But that’s where the similarity ends.

In Antal’s cell, the electrolyte is alkaline potassium hydroxide, not sulphuric acid. It is kept under pressure to prevent it from boiling away at 400 degrees. The negative terminal, or cathode, which acts as a catalyst, is made of nickel and silver or platinum.

The positive terminal, or anode, is a porous ceramic column filled with charcoal powder. A piston keeps it pressurized, and serves at the attachment point for the electrical connection.

In operation, hydroxide ions in the electrolyte attack the carbon, creating carbon dioxide and water. The process releases energy.

The cell is fed air to provide the process with new oxygen, and it vents carbon dioxide.

The charcoal does not burn in the sense of a campfire burning. The reaction occurs entirely within the liquid of the fuel cell.

what voltage per cell? What kind of current per gram of carbon consumed? details damnit! This sounds really promiseing!

So now we need to check the keyboard connection before sitting down to a public computer. Lovely. I see two or three sides here but suspect that it will mostly be used for evil. Doesn’t mean I wouldn’t like one, just in case… 😉

The Blog | Bob Cesca: And You Call Yourself A Homeland Security Advisor? | The Huffington Post
Fran Townsend, Homeland Security Advisor to President Bush, was on Fox News Sunday this morning and proudly stated something about as preposterous as anything to come out of the White House this week.

She reasoned that we weren’t alarmed about the British company managing our major ports after the London bombings, so why should be alarmed about the Dubai Ports deal.

Doublespeak anyone? Do these idiots in the White House really think that the public is this stupid? Or is it that they are so far into never never land that they just don’t think before opening their mouths? Or something entirely different? Alien mind control implants maybe? Or have they been turned into pod people?

Link above goes to a good article on a bad subject.

Trying to get to what the user ACTUALLY wants (or needs (which is another thing entirely)) out of them is sometimes (most of the time?) interesting. This Dilbert illustrates the process rather well I think…

Humor?
