Yes, I'm sure we all agree that Don Runkle is a bone head.
He has an engine to sell and he's not going to let facts get in the way of his sales pitch. He is correct that most of the current sources of electricity are polluters, but to claim that "EcoMotors’ engine technology enables car companies to produce diesel-powered vehicles that have a lower, overall carbon footprint than
any electric automobile available today." is a bold faced lie.
As Gavin pointed out, anyone who uses solar or wind power is going to have a much lower carbon footprint.
Sadly, he's singing the song that most people want to hear: No need to change your lifestyle, you can keep on doing what you're doing, just use my engine. And since that's what people want to hear, that's who they will listen to.
What a world we live in...
