Henrik Fisker, the storied car designer who has shaped Aston Martins, Fords and BMWs, told the Reuters Autos Summit this week that he now wants a starring role in the green revolution.

But he also wants to make the world safe for sports cars for generations to come.

"Being a car enthusiast and loving cars, to be quite honest, I could not imagine a life without a beautiful, fast sports car," Fisker said. "I needed to do something to make sure that I could drive one of those nice cars, my children could drive one of those beautiful, fast cars."

So what was Fisker's inspiration? What was the epiphany when he realized that the world was ready for the upcoming Fisker Karma, a $90,000 plug-in hybrid with 50 miles of all-electric fun?

Leonardo DiCaprio...in a Prius.

"A couple of years ago it started, by people who were maybe a little ahead of their time. You saw some movie starts like Leonardo DiCaprio buying a Prius.

"He could have bought any car in the world, and I remember seeing that on television and thinking to myself, you know, when you've got a guy who could buy any Ferrari or Rolls Royce and he's buying a Prius, you know something is changing dramatically."

His advice: build fast!

For most of us, printing e-mails or making copies is just part of the daily routine in the office. But, the paper we use does come from somewhere. Last week, we had the opportunity to visit Stora Enso's Nymolla Mill in southern Sweden to get an exclusive look at how MultiCopy paper is made. Nymolla is an integrated mill (it produces pulp and paper on the same site) and most of the wood used is sourced locally. Also interesting, the mill is the only one I could find in the world that emits zero carbon dioxide from fossil fuels during the paper making process. Check out my look inside the Nymolla Mill.
