These numbers do not provide an argument for desalination on anything like the hypothesized scale, much less an argument for nuclear energy per se. But they provide an illustration of the ways in which having ample energy supplies can help to ease the support of a larger world population. 

Almost a billion metric tons of C02 are sequestered in 2025. Then, hydrogen is produced from coal, oil and gas fields, with the carbon dioxide extracted and sequestered cheaply at the source. Large-scale renewable sources and nuclear energy are producing hydrogen by electrolysis come 2030. 

A particularly intriguing potential application of this reaction is the upgrading of the products of Fischer-Tropsch catalysis to increase the eventual yield of desirable n-aUcane chain lengths (typically C9-C19). FT catalysis, already practiced on a large scale commercially, may prove to be a key route to the future utilization of coal, biomass, or other nonpetroleum carbon sources (including CO2 reduction powered by solar, wind, or nuclear energy) [51, 52]. 

We performed a detailed comparison of the economic scale of radiation use in the fields of industry [4], agriculture [5], and medicine [6] in Japan and the United States. The comparison between Japan and the United States was also done for an economic index regarding market creation of products obtained from use of both radiation and nuclear energy [7]. The results of our study are compared for the year 1997. 

Our long-range energy future clearly must be safe nuclear energy, which should increasingly free still remaining fossil fuels as sources for convenient transportation fuels and as raw materials for synthesis of plastics, chemicals, and other substances. Eventually, however, in the not too distant future we will need to make synthetic hydrocarbons on a large scale. 

In Table 16-2, the time scale for elementary activated motion is given in the first place. It is converted into an energy scale by virtue of the E = (2n-h/t) relation, If we assume that the atomic jump length a is 2 A, the time scale may be converted into a diffusion coefficient scale by D = az/(2-t). One notes that (with the exception of /J-NMR) nuclear spectroscopies monitor the atomic jump behavior of relatively fast diffusing species. 

The sizes and energy scales of atomic and nuclear processes are very different. These differences allow us to consider them separately. 

The original state / (orbital energy of the occupied state for particular clumped nuclear structure) is by this correction shifted on the energy scale to a new position,... 

We used the Gd targets for a number of charged-particle reaction experiments for nuclear structure studies. 0 For one of the targets, a sample triton spectrum from the °Gd (p,t) °Gd reaction is shown in Fig. 1 which is a computer reconstruction of the original data on a linear energy scale and combines the results of five separate experiments. Each experiment revealed only a portion ( 20%) of the total spectrum. The spectrum is of excellent quality and, in particular, is free from contaminating peaks caused by other rare-earth materials.
