http://www.kurzweilai.net/the-world-can-be-powered-by-alternative-energy-using-todays-technology-in-20-40-years - Study by Stanford professors showing that we can meet energy needs using wind, solar and hydroelectric power, without even factoring in advances in solar technology.

"By perfecting the environment for the bacteria to do what they already do in nature, the new approach can be three to ten times more efficient than standard electrolysis."

- "People typically think of Hiroshima or the Chernobyl disaster when they hear the word nuclear. And when they hear it they should think sun... because what they are building is a miniature synthetic star. A fusion reaction is a star... a star in a jar"

- Zero-point energy. Uncontroversial that it exists, but highly controversial whether it can be harnessed.

Solar raft
Thought: Solar rafts floating on oceans near equatorial regions, more efficient than OTEC and wouldn't tak up land area. Sea conditions there are generally benign. Rafts in grid could be spread out a bit to let in light underneath. Underneath they would also create a floating habitat as happens naturally with large floating objects in the ocean. This provides an anchor for plants which allows fish to hide in an otherwise open ocean. It could perhaps be an automated site for liquifying hydrogen that could be split from seawater, aiding the hydrogen economy. This could be shipped or piped around the world.
