The Department of Energy is hosting an Earth Day expo tomorrow from 11am to 2pm at their L'Enfant Plaza headquarters. Participants will include DOE agencies, EPA, USPS, and a number of other organizations such as the National Capital Planning Commission. I'll be displaying my MS along with someone involved with the Advanced Technology Vehicles Manufacturing (ATVM) program. Feel free to stop by if you're in DC and want something interesting to do during lunch break. Hope to see you around!
