Nuclear Energy Can Save US--America�s 100 nukes equal four million barrels of oil per day.


Billions of lives and civilization itself may be at risk from the Global Warming & End of Cheap Oil, Crisis. Rising sea levels and rising oil prices could be the end of civilization as we know it. The problem is so huge that the most powerful answer, many nuclear plants, must be deployed. Currently, America‘s 100 nukes deliver the energy of four million barrels of oil per day. Wind and solar cannot do the job, and may delay the real answer too long. Still, all kinds of clean energy, plus conservation, plus reducing deforestation, will be needed to help the poor half of the world, and for civilization to survive through this century.

What Does CO2 Gas Weigh?

The weight of the CO2 molecule is the combined weight of one carbon, and two oxygen atoms. Each atom's weight depends on the number of nucleotides, protons and neutrons, in its nucleus. The carbon atom is atomic number 6, meaning 6 protons in the nucleus. Carbon has an atomic weight of 12, with six protons and six neutrons (neutral particles) in the nucleus. Likewise oxygen is atomic number 8, and atomic weight 16; 16 particles in the nucleus.
When a carbon atom burns, it is oxidized by oxygen to form the CO2 molecule. This molecule has a combined weight of 12 + 16 + !6 or 44 nucleotides. It is therefore 44 over 12, or 3.66 times the weight of one carbon atom. When one carbon atom burns the CO2 molecule is 3.66 times the weight of the carbon atom; when one pound of pure carbon burns, 3.66 pounds of CO2 is formed; when one ton of carbon is burned, 3.66 tons of CO2 is formed; when one billion tons of coal (typical year for America) are burned, 3.66B tons should be expected.
The US produces 6 billion tons of CO2 per year (eis.doe.gov), and 85% , or 5.1B tons is from fossil fuels. If one billion tons coal produced 3.3B tons CO2, all of the remaining oil and natural gas would only give 1.8 billion tons, which seems unlikely. The discrepancy is because coal burning is only 75% efficient (Taftan). It may therefore, only emit 3.3B tons X 75%, or 2.5B tons CO2, with the remainder. 0 2.6B tons from oil and natural gas.This now seems reasonable, e.g., natural gas burns so much more completely and emissions from burning are so much less than coal.
This is consistent with the data in Post "Clean Coal" and Global Warming, from a NY Times article, showing that coal burning produces 1897 pounds of CO2 per million BTU; while natural gas, much more efficient, emits only 842 pounds.

you never tied nuclear energy into this article >_<
