    1. The advantage of ocean currents is their stability. They flow with little fluctuation in speed and direction, giving them a capacity factor — a measure of how often the system is generating — of 50-70%, compared with around 29% for onshore wind and 15% for solar.

      Have other coastal countries other than Japan explored the capacity factor for tidal energy of the currents off their shoreline? Are other currents as promising as the Kuroshio current?

    2. Japan’s New Energy and Industrial Technology Development Organization (NEDO) estimates the Kuroshio Current could potentially generate as much as 200 gigawatts — about 60% of Japan’s present generating capacity.

      This is quite a significant percentage of Japan's total power needs.
