Inexpensive solar cells

Earth receives more solar energy in one hour than the entire planet currently consumes in a year.

With new technology close to the green plant's photosynthesis it's now possible to make solar cells less expensive.

Based on the principle of photosynthesis -- the biochemical process by which plants convert light energy into carbohydrate (sugar, their food) -- the Graetzel solar cell is composed of a porous layer of nanoparticles of a white pigment, titanium dioxide, covered with a molecular dye that absorbs sunlight, like the chlorophyll in green leaves. The pigment-coated titanium dioxide is immersed in an electrolyte solution, and a platinum based catalyst completes the package.

  1. Industrial Society Destroys Mind and Environment.

    The link between Mind and Social / Environmental-Issues.

    The fast-paced, consumerist lifestyle of Industrial Society is causing exponential rise in psychological problems besides destroying the environment. All issues are interlinked. Our Minds cannot be peaceful when attention-spans are down to nanoseconds, microseconds and milliseconds. Our Minds cannot be peaceful if we destroy Nature.

    The first rule of sustainability is - destroy less.

    The fewer things we make the more sustainable we are.

    A society that destroys ecosystems for "consumer goods" in addition to food, clothing and shelter is the least sustainable - and will exist for the shortest duration.

    Industrial society has destroyed necessary things [animals, trees, air, water and land] for making unnecessary things [consumer goods].

    In "Industrial Society" work turns into overwork, unnecessary work, destructive work.

    "Growth Rate" - "Economy Rate" - "GDP"
    These are figures of "Ecocide".
    These are figures of "crimes against Nature".
    These are figures of "destruction of Ecosystems".
    These are figures of "Insanity, Abnormality and Criminality".

    Infinite growth and development on a small planet that is just 40,000 km in circumference? - Industrial Society is insane.
