Biogas as a resource-efficient vehicle fuel

Trends in Biotechnology, 2008
There are currently strong incentives for increased use of renewable fuels in the transport sector worldwide. However, some bioethanol and biodiesel production routes have limitations with regard to resource efficiency and reduction of greenhouse gases. More efficient biofuel systems are those based on lignocelluloses and novel conversion technologies.

On efficient utilization of fuels

Energy, 1982
Abstract Various methods are developed to conserve fuels by increasing the efficiencies of heat engines. These efforts are limited by fundamental constraints on efficiency, as specified by the Carnot engine. We consider a cyclic process during which heat is converted into work while no other body, except the atmosphere, acts as both the source and ...
