Demo is a 12-issue series of comic books by writer Brian Wood and artist Becky Cloonan, published 2003-2004 by Ai T/Planet Lar. Each issue is an isolated story, but they all revolve around the lives of young people. Originally, the series was intended to focus on young people with supernatural powers - indeed, many of the issues do just that - but as the year progressed, the stories increasingly focused on people, relationships, and emotions, and the "supernatural" angle was quietly deemphasized.
DEMO (DEMOnstration Power Plant) is a proposed nuclear fusion power plant that is intended to build upon the expected success of the ITER (originally an acronym for International Thermonuclear Experimental Reactor) nuclear fusion power plant. Whereas ITER's goal is to produce 500 million watts of fusion power for at least 500 seconds, the goal of DEMO will be to produce at least four times that much fusion power on a continual basis. Moreover, while ITER's goal is to produce 10 times as much power as is required for ignition, DEMO's goal is to produce 25 times as much power.
