Thermoelectricity and heat balance in a metal/dot/metal junction
In this paper, we report on numerical calculations of stationary thermoelectric responses in a metal/dot/metal junction. We derive the Landauer expressions for both the electric and the heat currents, and first discuss the question of heat balance. Secondly, we calculate the Peltier coefficient in the non–linear response regime, and discuss its relation with the Seebeck coefficient, and finally ...

Technical and economic analyses of a hydrogen-fed gas turbine with steam injection and co-generation
Enel has been working on a hydrogen programme dealing with both hydrogen production and uses. The first phase deals with a hydrogen-fed, gas turbine-based co-generative cycle, in which steam injection in the gas turbine itself is adopted in order to couple high process efficiencies with very low nitrous oxide emissions. This paper presents the main results of the co-generative cycle thermodynamic ...

Focus Bioenergy No 7 2004: Biofuels - heating for the future
Biofuels for heating of homes and properties is rapidly making headway. Environmentally friendly, comfortable and price-worthy small-scale heating with biofuels is done using pellets or briquettes. Changing an oil burner for a pellets burner or replacing electric heating with a pellet-burning stove is often very profitable. It demands less effort than wood firing but somewhat more work than using ...
