The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..

This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.
