Adam Denison of GM mentioned to me of an upcoming alternative transportation and energy festival happening in Boston from September 28-29, 2007 at Boston City Hall Plaza. for more information, check out the website – http://www.altwheels.org/
Many of the automotive industry are sponsors, including GM, as well as some energy companies, including KeySpan and NStar.
Worth checking out if you are in the area – topics include hybrid, hydogen fuel-cell, ethanol, CNG, green buildings, biodiesel, wind power, etc. Thanks to Adam for giving me the heads-up on this.
