Abstract: A system for identifying migration direction of natural gases is provided and may include a network of 4He gas sensors and a migration monitoring hub. The network of 4He gas sensors may be operable to identify a 4He concentration in gas samples. The migration monitoring hub may be in communication with the network of 4He gas sensors and may comprise a user interface and a processor. The processor may be operable to determine a direction of increasing 4He concentration and map increasing 4He concentration. The user interface may be operable to display migration information. A method for identifying migration direction of natural gases is also provided and may include isolating a target portion of a petroleum exploration environment, detecting gas samples from a network of 4He gas sensors, identifying a 4He concentration in the gas samples, and determining a direction of increasing 4He concentration in the gas samples.

Abstract: The present disclosure describes a sun shade and a parking shade for a parking lot that includes a plurality of parking spots and one or more driving lanes. One sun shade includes: a panel that is configured to be inflated with a lifting gas to create a buoyant force and comprises hooks or eyelets for attaching tethers; one or more photochromic surfaces that reversibly darken on exposure to ultraviolet radiation and are arranged on a top surface of the panel, wherein portions of the panel that overlap with the one or more photochromic surfaces are transparent; and one or more photovoltaic units that are arranged on the top surface of the panel.
