    What does a fish know of water in which it swims all its life? What does a man know of nature of which he is an integral part? The ancient answer is: he knows and he knows not. (cited in Saraswati, 1995 (Ed) Man in Nature)

    The more I have learned in life, and I have learned a lot, the less confident I am in what I know. From this, I conclude that adamancy is a sign of ignorance. M. Ferguson 2010- Polymathica

Solar Powering the way forward

Some interesting observations about the future for Solar power as a source of energy.  The comparison is being made with the computer chip; increase in power and reduction in cost over time.

Whereas alternatives such as "clean coal" and "next generation" nuclear have yet to be costed in reality, solar provides real-time evidence of its reducing costs and increasing capacity.

The figures cited in this science alert [Solar power's steep learning curve]  indicate that in california during the 1980s the cost reduced on average 11% per year from 25cents/kWh [energy] to around 12 c/kWh.

IT it also cited that prices from 1980- 1995 for Photovoltaic energy dropped 35%, wind power 18% in contrast to Coal at 3% per year.

"In both concentrating solar power and solar photovoltaics, three factors are at work. The first is research and development of better technology. The second is manufacturing economies of scale. The third is the drive toward ever larger installations. Taken together, the three create a juggernaut of lower prices."
