This, electrical power, is a very common happening in the universe. For example, the nervous system of the human body is as a electrical grid. Just as electricity flows through nerves via neurotransmitters signal so to may a water current/tide be released to pass energy. Tidal power is similar. Tidal power can transform the useful energy of natural water currents to benefit humankind.
By recognizing tidal power as a source of energy, as a current passes electricity in a circuit, we can harvest it and turn it into potential energy, and then release it, at will, as kinetic energy, with the intention that people can benefit from it.
However, there does come a time when water flow, such as in the case of a storm where the current can cause overcharging that would lead to fires and explosions, near the Cape Cod Canal. That point, the point where energy may become too powerful to safely harvest should be determined as a safety transmission level, and above that level power harvesting should be halted. This means that in the event of a storm it is important to release the full amount of these power turbines by cutting their resistance in the power conversion state, in order to prevent dangerous overcharging which could cause explosions and fires.
