I just saw this vehicle that is in development at GM. The "Volt" (as it is being called) is essentially the idea I was talking about in the last blog entry. Rather than being a pure "Flex Fuel Hybrid," the Volt is essentially an electric car. The developer points out that this vehicle also sports a flex fuel assist engine for when the electric power (acquired by plugging in) is low.
While this concept car is not exactly what I was talking about, it at least proves that people are thinking about the concept. Score one for innovation.
