Abstract: A deep ocean current power plant comprises a current generator group, a floating midway platform, a generator anchorage system, a midway platform anchorage system, and at least one power transmission-and-distribution cable. The constructing procedure of the deep ocean current power plant comprises following steps of sea-cast anchoring and cable-numbering; platform assembling and undersea anchoring; current generator group anchoring; and testing and correcting a stability of whole structure.

Abstract: A compound solar water heating and dehumidifying device including an adsorption bed disposed at a lower rim of a plate type heat collector of a solar water heating element for causing a heat collector element to absorb heat in the day-time and the adsorption bed to regenerate and accumulate heat. At night, the heat of adsorption and heat of condensation are released to the heat collector element to retard the drop of temperature of water in water channels that are in contact with the heat collector element. Therefore, dissipation of heat from the hot water in a water tank may be retarded and water moisture may be removed.
