There is disclosed a portable life support system with a component for removal of at least one selected gas. In an embodiment, the system includes a supported liquid membrane having a first side and a second side in opposition to one another, the first side configured for disposition toward an astronaut and the second side configured for disposition toward a vacuum atmosphere. The system further includes an ionic liquid disposed between the first side and the second side of the supported liquid membrane, the ionic liquid configured for removal of at least one selected gas from a region housing the astronaut adjacent the first side of the supported liquid membrane to the vacuum atmosphere adjacent the second side of the supported liquid membrane. Other embodiments are also disclosed.

Apparatus and method are described for enhancing performance of an alcohol fueled engine during cold conditions, with such enhancement being particularly effected by generation of ether to assist cold operation including starting and/or to achieve reduced emissions during cold running. Dimethyl ether is generated by catalytic dehydration of vaporized methanol using a catalyst, preferably fluorinated alumina. Apparatus is disclosed for generating dimethyl ether on board as needed for immediate mixing with combustion air and methanol and/or for storage to enable later mixing of the dimethyl ether with combustion air and methanol to effect subsequent cold starts and/or cold running operations.
