When I'm not rescuing little birds from drainpipes, I like to save the planet in other ways. This morning, I decided to help reduce demands on the world's limited petrochemical resources by freewheeling my car into town. I live near the top of a hill, and the town is a mile away in the bottom of the valley. I actually managed to coast my car all the way from my front drive right into town and park - with the car in neutral all the way. What's more, I had to give way to other traffic twice en route (pardon my French).
Now, if only I could figure out a way of breaking not just the traffic laws, but the laws of thermodynamics, I might be able to freewheel that car of mine all the way back up that hill.
