Coffee-Powered Batteries

Study links MS to mononucleosis virus [cnn.com]--I just knew those bastards at Micro$oft were contributing to more than just the spreading of electronic virii. I'm just waiting to see the study that shows a causal relationship between room-temp IQ and use of M$ products. Interesting question: just which way does the causality go? I suspect both ways.

M$ zealots and shills: if you are actually responding to this seriously, substitute tech iq for iq, and shut up.

So now...

Fair-trade coffee

[leastsquares]

Coffee is a great source of poower, but I need lots of it. So, being a considerate citizen of the world, I would like to buy fairly-traded [fairtrade.org.uk].coffee.

Is there anywhere in California that sells such stuff, or is that not the "American way"?

I've already given up trying to find fair-trade bananas (another good source of early-morning energy).

Look here [oxfamamerica.org] for *tons* of places in California.

Cool... thanks.

Judging by the address, one of the listed places is even within walking distance from my apartment.

Java Server

[CamMac]

I can't wait to see the first Coffee powered server.

After the demise of the potato powered server [std.com], it'll be great to see anouther organically powered server.

This could be a big payoff...

At first, bacteria are mixed with the coffee grounds and dehydrate the moisture

Good idea! Dehydrated moisture can fetch up to $5000/kg on the black market!

If you use some of Pitr's experimental Super Triple Espresso [userfriendly.org], you oughta be able to light up Chicago.

I'd love to be a bored scientist

[eaddict]

I often think of how things are found out/invented. I think boredom has allowed creation of many more things than we realize. Why coffe grounds now? Well, someone was doing some experiments and someone else had to make a new pot of coffee and.... Wonder what might be next. Any ideas?

You can buy one of these at the toy store!

[rufusdufus]

I was at a Toy store [Imaginarium] last night and they were selling a clock that runs on Potatoes..or a whole list of things, one of them being coffee grounds.

Re:Coffee is one thing... just not Hazelnut Coffee

Read the article, Einstein. It's about used coffee grounds. Of course, they just use them as a carbon source, which is kind of a silly idea, because they're wonderful for compost, so if you're going to go to the trouble of recycling them, they'd make better fertilizer...

Diversification

[jaseman21]

I think that it's just great that sony is making coffee-powered batteries. Maybe overpriced coffee houses will start selling batteries...
