The power barn system provides a way to eliminate greenhouse gas (GHG) emissions from livestock. The power barn system seals and traps the methane gas that is emitted from the livestock and converts the methane into electric power and carbon dioxide to enhance plant growth. The power barn system uses PV solar arrays and plastic sheeting to make sealed, airtight structures. The carbon dioxide is provided to one or more sealed greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby completely eliminating greenhouse gas emissions from livestock. The power plant uses the methane at peak times at night while solar panels supply power during the day producing zero emission and 24/7 electricity at better than market rates.

A method of preparing a flowering plant product in hypobarically- and hypoxically-controlled atmospheres is disclosed. The method includes providing a simulated high-altitude controlled atmosphere (SHACA) room having a chamber, a plant support structure disposed within the chamber, and a microclimate control system operable to establish and maintain within the chamber a simulated high-altitude environment having an oxygen (O2) partial pressure of less than 20 kRa and, optionally, an overall pressure of less than 97 kPa. The method also includes disposing a flowering plant on the plant support structure, and exposing the flowering plant to the simulated high-altitude environment within the chamber. A simulated high-altitude CA room for cultivating and processing flowering plants in a hypobaric and hypoxic atmosphere is also provided.

A system for obtaining water and carbon dioxide from an incoming first gas stream. The system comprises a first inlet for said incoming first gas stream, a first sorbent station comprising a first sorbent material for removing water vapour from said first gas stream, a second sorbent station comprising a second sorbent material for removing carbon dioxide from said first gas stream; and a first exhaust for said first gas stream. The system is configured to flow said first gas stream through the first inlet, the first sorbent station, the second sorbent station and the first exhaust. The system may be used in an environmentally controlled facility for growing plant material or in a building space conditioning. The present invention may therefore enable plant cultivation and/or building space conditioning whilst removing carbon dioxide from the atmosphere and therefore may help to combat climate change and benefit the environment, if implemented on a sufficient scale.
