The Black Magic Carpet for Water and Power Production is the first innovation that combines simultaneous steam and power generation using an intelligent membrane with dual capabilities. PVDF/graphene membrane is used in the application of this BMC-WP. This product uses PVDF/graphene solar evaporation membranes to achieve sun-driven freshwater production and wave-driven power generation. The membrane can convert mechanical wave energy into electrical energy. The PVDF/graphene membrane produced a voltage of 2.6 V (±1.3 V) and a power density of 2.11 W m−2 in 1-Hz waves. In addition, under one sun illumination (1 kW m−2), stacked graphene and PVDF developed a hydrophobic interface water channel structure with a water production rate of 1.2 kg m−2 h−1 and a solar-thermal energy conversion efficiency of 84%. The water sampled was within WHO drinking water quality criteria. The developers constructed a product using a single solar evaporator to acquire fresh water and create power simultaneously.
