Abstract: A lightweight building assembly can include an insulation blanket, an insulation base, a frame, and tensioned elements. The insulation blanket can define an insulation blanket axis about which the insulation blanket can rotate. The insulation blanket can have a peripheral wall portion positioned at a varying radial distance from the insulation blanket axis. The insulation base can have a first membrane and can be coupled to and support the insulation blanket. The frame can have a second membrane and can be coupled to and support the insulation base. The frame can be configured to move with respect to the insulation base. The tensioned elements can be wound about the insulation blanket, and each tensioned element can extend tangentially from the peripheral wall portion to the second membrane. The tensioned elements can combine to form a continuous tension circuit across the assembly, which assembly can be effective in multiple disparate climates.

Abstract: Methods separates a gas comprising providing a first electrode in ion-conducting contact with an electrolyte, providing a second electrode in ion-conducting contact with the electrolyte, wherein the second electrode comprises a liquid metal, providing a displacing material comprising a first surface in contact with the second electrode and a second surface exposed to an environment outside the second electrode, wherein said material permits flow of gas and impedes flow of liquid metal, and establishing a potential between the first and second electrodes, whereby gas flows toward the liquid metal. Other aspects include methods and apparatuses comprising electrodes, electrolytes and displacing materials.
