Abstract: An automated stirling-pelitier liquid air battery includes: a cryocooler to cool a tip of a cold head to cryogenic temperatures, the cryocooler resting in a cryocooler support; the cryocooler support to change a level of the cryocooler in a dewar to maximize liquid air production, the dewar to hold the liquified air at low temperatures, the dewar having the cryocooler support, wherein the dewar further comprises: a polytetrafluoroethylene or glass inner shell that reduces conductive heat loss, and a polytetrafluoroethylene or glass threaded pipe connected to a liquid air transport subsystem; and the liquid air transport subsystem having a thermoelectric generator to generate output electricity from the liquid air received from the dewar.

Abstract: A dewar includes two coaxial openings of different sizes (e.g., to allow for interfacing with a Stirling cryocooler and a Stirling generator), a polytetrafluoroethylene or glass inner chamber (e.g., to reduce conductive heat transfer, particularly through the dewar neck), and an integrated, annular desiccant ring (e.g., for drying low-pressure, ambient air).

Abstract: The invention relates to a liquid air energy storage system. The storage system includes a cryocooler, a dewar, and a Sterling engine. The cryocooler cools a tip of a cold head to cryogenic temperatures, the cryocooler further includes a heat sink to reject heat from the cryocooler and a cold head that protrudes into a dewar through a cryocooler cavity, the cold head to condense ambient air to create liquified air in the dewar. The dewar holds the liquified air at low temperatures, the dewar having the cryocooler cavity and a Stirling cavity. The Stirling engine drives an electric generator, the Stirling engine further including a cold finger protruding into the dewar through the Stirling cavity, the cold finger to move the liquified air from the dewar to a Stirling heat sink; the Stirling heat sink to expand the liquified air; and the electric generator to generate output electricity.

Abstract: The invention relates to a bidirectional charging panel (BCP). The BCP includes a relay for controlling a combustion engine and a battery voltage sensor for monitoring a battery voltage. The BCP also includes a grid switch to transfer continuous power between the battery and a grid interface, where the grid interface further includes a grid voltage sensor for monitoring a grid voltage of a grid of devices and a grid direct current outlet to transfer power to and from a grid of devices. The BCP also includes a controller to manage the flow of power between the battery and the grid of devices, where the controller uses the relay to start or stop the combustion according to the battery voltage and uses the grid interface to transfer power from the grid of devices to the battery in response to determining the battery voltage is lower than the grid voltage.

Abstract: A vertical burial container comprising a midsection containment, upper cylindrical lid, interior volume, and a domed upper lid. The midsection containment comprises internal threads surrounding the upper circular opening and comprises a set of external threads surrounding the base. The external threads and the internal threads are mating threads to allow multiple containers to be threadably engaged for handling as a single unit. An upper cylindrical lid having external threads mated with the internal threads allows isolation of the interior volume of the midsection containment. Additionally, the vertical burial system additionally comprises an upper lid with internal threads for threadable engage with the internal threads. The various threads have respective thread lengths to accommodate either an upper lid or another midsection containment to be threadably engaged into the internal threads without displacing the inner cylindrical lid isolating the interior volume.
