- There was a recent article in the New Scientist that stated
- a world survey shows at least 50 nuclear warheads and 11
- nuclear reactors contributed by various countries, currently
- lying at the bottom of the oceans.
-
- Hope this is not indicative of the standards of nuclear
- disposal in the future.
-
- I am interested in solar energy harnessing by arrays of
- focussing mirrors, several systems are already operating
- here, in Saudi Arabia, France, etc.
-
- According to a physics text approx one horsepower or
- 750 watts of sunlight is available per square meter
- at the earth's surface in a high sun area such as
- the Mojave Desert in California.
- There have been recent articles in several journals
- asking to take a renewed look at this as a way of
- generating electricity.
- Given an efficiency rate of 20%, it still seems that
- with
- there is a lot of available energy for these systems.
- Perhaps 10 square feet (given solar for 10 hours per day)
- would yield enough to power a home for one year at
- 4000 kwhrs. An acre would power 4000 homes per year.
- 100 acres; 400,000 homes, etc. There are a number of
- desert areas which would be suitable.
- Personally I feel that the pollution caused by oil
- for energy consumption is too serious a health and
- nature hazard to consider it preferred.
- Nuclear is too hazardous, perhaps not from the concept
- of the systems but because of human negligence, and error, etc.
