If you haven't had the chance yet, there's still time to check out some very cool weather-related features at the "One Planet - Ours!" exhibit at the U.S. Botanic Garden through Oct. 13.

The exhibit highlights innovative technologies that capture solar energy, reuse rainwater and filter air, including a vertical axis wind turbine that can power one-third of the annual electricity for a family of four with 12 mph winds, rainscaping techniques for stormwater retention and an interactive solar-powered fountain.

You can take a virtual tour of exhibit features here, or check out some of the highlights in the following PDF documents: Vertical Axis Wind Turbine | Indoor Air Quality: Living-wall Biofilter | Rainscaping | Water: H2O = Life | Solar shed and solar-powered fountain | Solar America Cities | Solar-powered generator

See our full forecast through the weekend, and NatCast if you're headed to tonight's game at Nationals Park.

Hmmm...wonder if it's possible to buy a VAWT & set it up in your yard to generate some electricity. I notice that occasionally Dominion or somebody cuts off our power for no reason whatsoever, when I'm online.

It's the outages that happen when there's no bad weather that really put me off. Occasionally it's a squirrel or raccoon in a transformer, but sometimes some fool out on the Pike crashes his vehicle into a utility pole and cuts off the neighborhood. Then there was the time some months ago when some kids let their Mylar balloon go...and it got entangled in the power line "shorting out" the block!

Thanks for the note on the Botanical Garden exhibit. It's nice to live near a city where stuff like this comes around so often; I'd hate to have to drive hundreds of miles just to see something new.

Ann - THANK YOU for posting about this! I had no idea it was going on. I will be down there this weekend checking it out.

Plus it's a good excuse to go to the botanical garden, which is one of my favorite places in DC.
