    Have you had this happen to you? You mull over the meaning of a word, look at it from various viewpoints, explore its context and connotation, and poof - its meaning changes or shifts unexpectedly. Just had it with the word "renewable", loosely attributed to energies preferred for their sustainable and non-polluting properties. Fits on some energies, like wood, or mental energy, but not others. I think the word has been used to loosely, because in a way, nuclear energy is renewable (by re-processing), Negawatts are renewabe (by switching off or efficiency up). How is the sun re-new-able? It implies choice. Solar and other inexhausitble energies are "tappable" but not really (you may disagree here) ...

    Renewable (Energies)

    Does a dictionary entry help?

    Relating to a natural resource, such as solar energy, water, or wood, that is never used up or that can be replaced by new growth. Resources that are dependent on regrowth can sometimes be depleted beyond the point of renewability, as when the deforestation of land leads to desertification or when a commercially valuable species is harvested to extinction. Pollution can also make a renewable resource such as water unusable in a particular location. Compare nonrenewable.

    Got here and appreciate the image from Rethinking Japan's Energy Future, 2011-04-11 by J. Matthew Roney. Gist:

    A review of Japan's geothermal, wind, and solar energy potential shows that domestic renewable resources could easily power the world's third-largest economy.

    Hat tip: Sepp Hasslberger

    Geothermal is a potentially fierce competitor to petroleum type fuels. We can expect all kinds of tricks to make less of it, including outright false statements as to its potential, from petrochem interests.

    And then there is tidal and wave energy, which have made progress, too. Falling cost bring break-even much closer. BBC article and video on a recent second generation design.

    So is wave energy re-new-able, in that we can regrow it if we want to?

    Monica Anderson explains.

    Reductionism is an amazingly powerful strategy for leveraging the work of scientists and for disseminating the results in the form of re-usable models of structure and causality. But for some of the "remaining hard problem domains" such as Life (biology, psychology, ecology, etc), the World (world modeling, economies, sociology), Intelligence (understanding the brain, intelligence, and creating Artificial General Intelligences - AGI) and the problem of determining the semantics of language (e.g. text) Reductionism has failed. I claim that reductionist models cannot be created in these domains (which have been named "Bizarre Domains") and that we must use Model Free (Holistic) Methods for these domains. This has important implications for AGI research strategies.

    "AI is the last holdout of pure reductionism, if you will."

    AGI: Artificial General Intelligence. In later lectures she uses AN: Artificial iNtuition.

    Slow down and enjoy the presentation. 31:22
