Abstract

An apparatus, system, and method for CO₂ production and delivery is provided. The generator apparatus supplements or supplies CO₂ where it is desired, such as to plants growing in space, particularly within an environment control system (ECS). The various embodiments of the generator apparatus are designed to withstand outer space storage, travel, and environmental impacts on a prepared mycelial mass. One example embodiment comprises dual containers wherein an inner container holds the prepared mycelial mass and an exterior container further protects the interior container and collects and sequesters condensation. In this example each container has a least one wall having a passive gas filter which permits the transfer of CO₂ out of, and oxygen in, through the first wall and out of the second wall and into an external environment. The generator may be aided by methods and system components including a cover, protective barrier, and case.

Description

This abstract provides apparatus, systems, and methods for the production and delivery of CO₂. The generator apparatus replenishes or supplies CO₂ where needed, such as in space-grown plants, particularly within an environmental control system (ECS). Various embodiments of the generator apparatus are designed to withstand the effects of outer space storage, travel, and environmental conditions on the prepared mycelial clumps. One example embodiment includes a dual-container system, wherein the inner container holds the prepared mycelial clumps, and the outer container further protects the inner container and collects and seals condensate. In this example, each container has at least one wall with a passive gas filter that allows CO₂ to escape through the first wall and oxygen to enter, and to escape through the second wall and into the external environment. The generator can be aided in operation by means of method and system components including a cover, protective barriers, and a shell.
