“…Equations ( 2)-( 4) agree with the results in the literature [2,3,[5][6][7]. As we put values into equation (4), we get h ~ 0.5 m, of which the order of magnitude has been estimated in the previous section.…”

“…Tidal energy resources consist of differentials between high and low tides created by the gravitational interaction between the sun, moon, and earth's oceans (Tsantes, 1974). Elevation differences between high and low tides can be exploited directly for electrical power generation, and there are two prominent types of technologies that are being developed to capture this energy.…”

However, information about public interest in developing marine renewable energy technology, including tidal energy technology, in WA and the U.S. has been limited. Responses to a dichotomous choice referendum question on a mail survey sent to a representative sample of WA households were used to estimate residents' Willingness To Pay (WTP) for tidal energy R&D.Public preferences for policies to support tidal energy R&D were also assessed. WA households are WTP a median of $1.62 per month for tidal energy R&D, indicating public preference for an increase in public spending on tidal energy R&D over current levels. Public perceptions of potential social, environmental, and economic risks and benefits of developing tidal energy emerged as highly significant predictors of WTP.i

“…They do not explain the simple basis of tidal force fields. Nevertheless, there are many pedagogical papers meeting the interest in the topic [8][9][10][11][12][13]. The common interests in, e.g., ocean tides and astrophysical phenomena [14,15] invite to be obliged.…”

“…The common interests in, e.g., ocean tides and astrophysical phenomena [14,15] invite to be obliged. An introduction conceptually convincing is, e.g., in an inertial frame of reference to analyze the stresses in a rod in an inhomogeneous gravitational field [8,13]. However, in general, avoiding the formal comprehension of how to operate in accelerated frames of reference generates often confusion.…”

The motion of the earth relative to the sun inertial frame of reference is a superposition of the motion of the earth around the common center of mass of the moon and the earth and the motion of that center of mass around the sun. However, you get the resulting tidal force field due to the simultaneous existing of the moon and the sun by superposing a moon-induced tidal force field and a sun-induced tidal force field. Where, the moon-induced tidal force field is calculated as if the sun weren´t existing, and the sun-induced tidal force field is calculated as if the moon weren´t existing. The situation may lead to confusion. Thus, we give a formal conceptual account of the state of affairs, and argue that the cae is useful when introducing undergraduates to inertial forces and understanding Newtonian mechanics.
