The Week in Cleantech is a weekly roundup of our favorite cleantech and alt energy blog posts and stories from across the web. If you know of a good piece that you think should be included here, don't hesitate to let us know!

This week, we particularly liked...

On Monday, David Talbot at MIT's Technology Review told us how to nanocharge solar. Nanotech's role in cleantech should continue to increase steadily in the years ahead. On that note, Inside Greentech discusses a report on cleantech and nanotech.

On Wednesday, Stephen Trimble at Defense Tech told us that the army was foreseeing a natural gas crisis. Those who follow the coal-to-liquid space know that the army has been looking into this. But that would be at best a band-aid solution.

On Wednesday, Kevin Bullis at MIT's Technology Review discussed a recent MIT study arguing that the future is precarious for coal. Making coal clean will be, in my view, one of the most dynamic areas of cleantech research in the coming decade.

On Friday, the WSJ's Energy Roundup wondered whether Qatar could become a wind power giant. While the potential would be there for off-shore wind, Qatar would have a long way to go to catch up to the leaders pack.

On Friday, Tyler Hamilton at Clean Break noted how last week was a busy one for Canadian cleantech firms.

On Friday, the WSJ's Energy Roundup sang the Ballad of the sad CAFE for us. I have one thing to say about large auto makers' constant complaining about raising fuel efficiency and pollution standards: yaaaaawwwwnnnnnn...

On Friday, Jack Uldrich at The Motley Fool informed us that FuelCell was generating a spark. I too was surprised by Clean Edge's numbers, but definitely worth keeping an eye on.
