Advances in high temperature components for AMTEC (alkali metal thermal-to-electric converter)

Description: Long lifetimes are required for AMTEC (or sodium heat engine) components for aerospace and terrestrial applications, and the high heat input temperature as well as the alkali metal liquid and vapor environment places unusual demands on the materials used to construct AMTEC devices. In addition, it is important to maximize device efficiency and power density, while maintaining a long life capability. In addition to the electrode, which must provide both efficient electrode kinetics, transport of… more

A Critique of Kellehear's Transcendent Society

Description: Article responding to Allen Kellehear's cultural analysis based on nine Mormon near-death experiences (NDEs) did not reflect the diversity of near-death visions from other cultures. It suggests that these Mormon NDEs were neither as utopian as Kellehear assumed nor representative of contemporary NDE reports, and that a more complete analysis would reveal a variety of NDEs and otherworld visions reflecting the experiencers' sociocultural background.
