Global production of farmed fish has more than doubled in the past 15 years. The United States today imports about 70% of its fish food consumption resulting in large economic deficit. Aquaculture systems could be a possible solution to it and for that, we propose a modern approach “Sustainable Economic Aquaculture From Autonomously Real-time Monitoring (SEA-FARM) System” that can be deployed to high diversity aquaculture farm with freshwater or marine. SEA- FARM will be a multi-disciplinary effort from concept to operation, towards minimizing the energy consumption and maximizing the efficiency of the operation for a desirable precision of aquaculture assessment. To accomplish the goal, we plan to store energy capacitively as the cost must be amortized over the storage unit’s lifetime, including continuous operation, making our capacitive approach economically advantageous.
Dielectric capacitive storage provides the necessary power density and lifetime properties required for SEA-FARM, but falls short when it comes to gravimetric energy storage. Energy density is depended on two factors; dielectric constant and breakdown field. Efforts have been made to increase the energy density through nanocomposites by mixing high dielectric ferroelectric nanopowders with known high breakdown polymers through surface initiated polymerization assuming that overall energy density is enhanced. However, the interface of the nanoparticle and polymer matrix creates a void that acts as a charge concentrator, greatly reducing the breakdown field. We use an approach called thiol-alkene click chemistry to overcome this issue. By designing a thermally and electronically stable polymer that is cured through UV processing, functionalized high dielectric constant nanoparticles can be directly bonded into a high breakdown polymer matrix that enhances energy density. To achieve this, we need novel materials that will both withstand high electric fields (≥1 MV/cm) and maintain an extremely high dielectric constant (~30,000). The energy thus obtained is then used in SEA-FARM.
