Question

How many high peaks occur in a single pool tidal system?

(a) 1

(b) 2

(c) 3

(d) 4

This question was addressed to me during an interview.

The query is from Tidal Power in portion Ocean Energy & Geothermal Energy of Energy Engineering

Answer 1

Correct choice is (b) 2

The best explanation: In the simple single pool system two high peaks, short duration power outputs occur every tidal period. Such peaks require large turbine-generators that remain idle much of the time. The power peaks also occur at different times every day (50 min later each successive day), at times of high and low tides.
