Reading Roundup is a regular feature of WebEchoes. It consists of links to articles and websites that I find interesting but don't have a enough to say to warrant a standalone post.
WorldChanging: Water filters -- "All you need is terracotta clay, a compliant cow and a match."
And coffee grounds...that part might be a bit expensive/hard for some people to get. I wonder how effective it is compared to other techniques such as activated carbon and reverse osmosis?
WorldChanging: I (heart) Fluff
While I do (heart) the marshmallow stuff, that isn't the what Cameron is talking about. Rather, Fluff, a product for soil amendment and building materials made from household waste. The production sequence is probably fascinating to get a consistent material. And probably quite energy intensive to produce. Beats using a landfill, I suppose.

Clean Coal Inches Closer With German Carbon Storage Plant « Earth2Tech
10 tons of CO2 an hour for 30MW? Yowza, its probably not a linear to scale up to 250MW, fuel usage probably being more efficient, but scaling it that way gives 83 tons an hour for a small production scale power plant. That's a lot of CO2.
WorldChanging: Why Not in America?
A look at why bicycling as a form of transportation hasn't caught on more in place other than Portland. Not surprisingly, more than anything its policy and infrastructure, according to the Washington Post.

An explanation of why Hydrogen as a energy source for automobiles is unlikely to ever be commonplace or affordable, and why it doesn't solve the problems of global warming, at least as currently envisaged.
