Keith, No, I don't have a website. I am one of the "old foggies" who just keeps his head down working every day. :-)
I do like your forum though. Art ----- Original Message ----- From: Keith Addison To: biofuel@yahoogroups.com Sent: Monday, April 26, 2004 11:12 AM Subject: Re: [biofuel] Re: Cellulose-Alcohol story.

I've never stopped making compost in the last 24 years, no matter where I've been, even in a small 19th floor flat without a balcony in urban Hong Kong.

Yes. We rant about the ridiculous "food miles" issue here every now and then, and more often about the need for localisation of both food and fuel production (closely related issues). >The farmer enters an unspoken agreement with nature that, if a crop >is produced, the residues must be put back into the soil to >regenerate the soil.

Average distance from farm to supermarket in the US is more than a thouand miles, according to one estimate I saw.

Okay, good. I never stop blowing it, sounds like you don't either - and it's NOT off-topic on a biofuels list! But, people either get it or they don't, as you can see. Previous time I did it was over the fuel from pig manure thing, and got told I hadn't presented any scientific evidence. :-/ Liebig debunked himself more than a century ago, but it's still gospel, eh?
