Hmm.. Tough questions..
1) The Rotary has been a main sponsor of the team since it's inception I believe. They let us "crash" with them during the parade by letting us use their trailer as a base of operations.
No we don't participate in any of their other events, but if they asked, we would gladly oblige..
2) 2 words. Solar Power...

j/k We had a portable generator with a 110v outlet that we always have to borrow at the last minute from our very gracious Fire Department, because the one we usually get at first never seems to start or is way too big for the task at hand.
Actually, solar power would be really cool. Maybe we will look into that.
And finally, the Segway Kevin is riding along side the robot is Marc's from Team 38, The Nonnebots, in neighboring Woodbury CT. He joined us after some bribing and went gliding with us in the parade, even though he didn't get to ride it most of the time cause 237 members "stole" it from him..
Every once in a while, we would have the robot and whoever was on the Segway do some syncronized spinning and get the crowd pumped up..
It was amusing.
