1. Bad. Best to get the bad news out of the way. Burning coal at home is making a comeback. Here is a suggestion for high school science teachers: get kids to analyze coal for its toxicity.

3. CNN has a video of a human-powered car. I've been thinking of this for ages.
Now if we can just get a cheap Chinese-made clone of it!
