摘要:
The concept is almost as simple as extracting free heat from the sun. Any geophysicist knows of the geothermal gradient and has thought at one time that eventually geothermal heat will have to be tapped as a source of energy. To quote a brochure published by the Los Alamos Scientific Laboratory (LASL), ‘Naturally heated rock in the earth's crust is one of the greatest sources of energy that is accessible to man.’ Why not, then, proceed? At its Fenton Hill, New Mexico, experimental site, (See Figure 1) LASL has found out that the concept may be somewhat oversimplified in practice. One cannot, in fact, just drill down a couple of wells and circulate water through a heat exchanger for the indefinite extraction of heat. Not yet, that is, on an indefinite time scale, or for reasonable c

摘要:
Solar‐terrestrial research has evolved rapidly in the 20 years since Sputnik 1 and Explorer 1 heralded the space age. Accelerating activity in space by many nations has led to considerable observational maturity in all facets of the field—solar, solar wind, magnetospheric, ionospheric, and upper atmospheric research. The directions of research have changed as exploration progressed. Two strong trends currently are evident: (1) more emphasis on the coupling of the various regions of space studied, and (2) more emphasis on physical processes that operate in these regions. Both of these trends represent a movement of solar‐terrestrial research out of phenomenology into quantitative studies. As might be predicted, the trends are accompanied by increased activity in modeling and intensified demand for theoretical work concomitant with more comprehensive experimental observa
