Dear All,                        Oct 31, 2012
    Two short items in the un-numbered pages of the Nov issue, although not 
strictly Naturens material, could impact the natural world locally and 
elsewhere.

    One, on about page 17, is a concept to capture solar energy using a 
modular, self repairing satellite transducer that transmits energy as 
microwaves to earth-bound receivers. If this could really be made to work at 
acceptable cost then the problem of carbon emissions would be fully solved. 
Shortly after WW2, Popular Science published a somewhat similar concept that 
Germany had intended to develop; except the transducer (as I recall) was 
just a disk and not self repairing. So it could take time.

    Two, on about page 21, is a chart of the world's 10 busiest container 
ports in terms of TEU volume.   Six of the ten are in China, eight of the 
ten are in Asia, one is in the middle East and one Western World port 
squeaks in by pooling the volume of two ports. Combining that with 
demographics in the Western World, economic problems in Europe and weakening 
of the Gulf Stream which will further impair European economies would 
suggest that Western Civilization and associated products such as 
Conservation Ethics are in for serious headwinds.
