I see the main challenge for us is in the field of energy, but to solve that problem I bet we have to go through a lot of minor challenges that none of us can foresee, what are those challenges? What do we need to accomplish these challenges? Manpower? Time? A Eureka moment (they are always handy)?
We have a great resource of human knowledge called Encyclopedia, but do we have a similar thing for the above questions?

This is being heralded as a monumental breakthrough by the community and may "rapidly advance research in the treatment of cancer, Alzheimer's and Parkinson's diseases, diabetes, arthritis, spinal cord injuries, strokes, burns and heart disease because scientists will have much greater access to stem cells." Good news for all."
