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.
