Abstract: A bioreactor for producing hydrogen gas and metabolites and methods for making and using the same. The bioreactor comprises a main reactor chamber, a semipermeable membrane, a sleeve, microorganism, such as cyanobacteria, for producing hydrogen gas and metabolites, a power supply, a substrate medium, a heating member, a plurality of tubing members, a collection reservoir, a pressure-sealed connecter member, a metabolite purifying filter member, a light source, and an agitator. The bioreactor utilizes light, fermentation, and other metabolic processes for the production of metabolites, derived from various microorganisms contained within the bioreactor through respective metabolic pathways.

Abstract: Systems and methods designed to facilitate a robust and secure aerial network that supports surveillance and delivery operations of electric battery-powered drones. These operations can be conducted in both autonomous and operator-controlled modes. The integrated system utilizes individual drones and base stations, each functioning as nodes within the aerial network and maintaining continuous internet connectivity. The base stations are equipped to serve as recharge and battery swap points for the drones. Furthermore, the network interfaces with a proprietary, secure internet-based application and servers, which enable the coordination and collaboration of drones, autonomous recharging, and comprehensive data collection. This advanced technology has global operability, extending its reach beyond terrestrial boundaries to other celestial bodies, as long as an internet connection is available.

Abstract: Compositions of heat treated, cross-linked polyvinylpyrrolidone (PVP) are disclosed that are generally in the form of an elastic, hydrophilic, water insoluble viscous cohesive mass of material that has many important medical uses including uses as a filler for implants. The present invention also involves a process for producing such compositions.
