 Mark, ready? Fundamentally, experts are there to tell you why certain things just won't work. And it takes a non-expert to be able to say, why not? How do we get energy to the billions of people around the world who have absolutely no access to energy? We need to find a way to generate the electricity locally. So we don't have to worry about transmitting it to them. Once you give them the energy, it changes the village. They will be able to find the jobs. They'll be able to do the thing that they have never been able to do before. The people, the masses, don't have to migrate from rural areas to the urban areas and essentially become the population towns where they have to live in the slums. So you should never put a limit on what can or cannot be done. If you put a great mind to it, every problem can be solved.
