Wirt explains that the invention of the electric motor revolutionized the way factories operate. With steam power, there was one central boiler which dictated how the factory had to be organized. As electric motors evolved, it became possible to make small motors that could be distributed around the plant to provide power to individual machines allowing for greater flexibility. Now, electric motors are everywhere, he says.

Martin Eberhard talks about the distribution plan for the new Electric Car. He mentions the restrictions and legal constraints for selling a car through a dealer. He believes direct distribution coupled with a gradual increase in the number of stores would be a critical factor in getting the electric car to the market. He finally notes that this strategy is easier than selling into an existing franchise.

Martin Eberhard discusses the shortfalls of using Solar Energy as a key component in manufacturing a car. He believes that using fuel-cells to drive cars is a huge stretch in imagination. He finally notes that a mix of plug-in hybrid and gasoline is a viable idea for an interim solution for alternative energy sources to drive a car.
