Can't get enough green in your life? Want to learn more about environmentally conscious products and energy-saving technology right here in the Charm City metroplex?

Well, then, the Greentech Maryland Conference and Expo may be for you. Marketed under the slogan "Wow! I didn't know that!" the shindig promises to have one of General Motors' futuristic fuel-cell concept cars on display, and more info about the all-electric Volt, which GM claims will go a fantastic 230 miles per gallon of gas.

The lineup of speakers - all supposedly strictly limited to 10-minute, "Twitter-style" talks - includes local politicos as well as a slew of folks from area corporations and businesses touting their green cred. It runs from 7:30 a.m. to 1:30 p.m. on Friday Sept. 18 at the Crowne Plaza Hotel in Timonium, 2004 Greenspring Drive. (And yes, that's even reachable by light rail.) It's not free - $60 for the day, but lunch is included. For more info and to register, go here.
