Scanning the news this morning, I found out that Honda has released an updated hydrogen fuel cell car that produces no carbon emissions. While it's going to be some time in getting the cost down of producing these cars (which is probably high; I doubt fuel cells can be mass-produced in a cost-efficient manner at this point), as well as developing a network of hydrogen fueling stations, this is a great step forward. Hopefully this happens sooner rather than later...as I'd like to buy one of these puppies once I have the need for regular car use.
Updated to add: On another note, I found an article (via Digg) about a self-sustainable skyscraper to be constructed in Dubai that will have built-in wind turbines that generate enough energy to power it 10 times over. This should be more notable than the never-ending Burj Dubai, which will be the tallest man-made structure in the world once the developers decide how tall they want it to be.
