The oceans contain a tremendous amount of thermal (internal) energy. Wqdg,2*hiz 2f nc.co:z hy, in gyn;2ealma4 y7)10u f.pagyaneneral, is it not possible to putga yaym0u)2a.e n1y7nl4;f ap this energy to useful work?
参考答案:
To
utilize the thermal energy in the ocean waters, a heat engine would need to be
developed that operated between two different temperatures. If surface temperature water was to be both
the source and the exhaust, then no work could be extracted. If the temperature difference between surface
and deep ocean waters were to be used, there would be considerable engineering
obstacles, high expense, and potential environmental difficulties involved in
having a heat engine that connected surface water and deep ocean water. Likewise, if the difference in temperature
between tropical water and arctic or Antarctic water were to be used, the same
type of major difficulties would be involved because of the large distances
involved.
