Abstract: A method, a food container, a lid, and pad for a food container that actively removes moisture in the food container without changing the food temperature inside the container in a meaningful way are disclosed herein. The removal of moisture is achieved by introducing a cold spot (below the dew point temperature) inside the food container that forces condensation of moisture near the cold spot. The condensed moisture is then captured by an absorbent element placed below, and preferably adjacent to/collocated with, the cold spot and between the cold spot and the stored food. The cold spot is preferably achieved by a properly chosen frozen substance such as an ice cube or a frozen gel packet or ice trapped inside an absorbent pad.

Abstract: A method and apparatus for enhanced oil recovery comprising separating CO2 gas from coal or flue emissions of a power plant, and flash freezing the CO2 gas with super chilled air, to form frozen CO2 ice blocks or cylinders, wherein the CO2 blocks or cylinders can then be inserted into an abandoned oil well, and the CO2 can be allowed to warm up and change phase to a gas, which enables the CO2 gas to mix with the oil, and helps reduce the viscosity of the oil and allows it to flow more freely, so that it can be pumped out using conventional equipment. A first application comprises having top and bottom valves and the CO2 blocks or cylinders being allowed to change phase to a gas while inside the injection pipe, to increase the pressure therein, such that, by opening the bottom valve, pressurized jets of CO2 gas can be released into the oil, causing the oil to mix vigorously with the carbon dioxide gas, and reduce the viscosity thereof.
