Abstract: Provided are powered roof racks for tall vehicles, configured for cargo loading or unloading near to and parallel to the ground. The cargo is lifted to or lowered from roof height using an electric drive. Cargo motion comprises two separate essentially linear motions. The motion on and off of the roof is linear and essentially horizontal. The motion between roof height and the near ground level loading/unloading position is linear and near vertical. During all operations the load remains parallel to the ground. The majority of cargo load is supported on the ground during loading/unloading. All parts may be stored in a low profile roof mounted package when not in use, and ensures that setup and teardown uses a minimal number of easy to execute steps.

Abstract: Provided are methods and devices for storing and generating oxygen from a low temperature oxygen generating liquid. The oxygen storage method may use lithium chlorate plus water to store oxygen wherein all solids that may be present enter solution for delivery as a liquid to a reaction vessel. The oxygen production method may be a batch process with steps to heat the liquid, boil out the water, thermally decompose the lithium chlorate and then rinse out the remaining product. The apparatus for oxygen generation may use multiple reaction vessels operating sequentially to produce a continuous flow of oxygen with a rinse step in a separate area from the heat application area to remove end product solid. The device for oxygen storage includes a storage vessel and is configured to heat the oxygen generating liquid using waste heat present in the rinse liquid.
