The New Fuel: Efficiency

Strategic Planning for Energy and the Environment, 2011
ABSTRACT Emerging new technologies can drastically reduce the energy consumption of buildings in the United States. In this article we look at overall energy usage, where our supply sources for energy emanate, and how they are used throughout the United States in the different demand sectors.

Turbocharging for Fuel Efficiency

SAE Technical Paper Series, 1983
The arguments are given for the application of a 1.3 litre turbocharged spark ignition engine, as a substitute for a 2 litre normally aspirated engine as the power plant for a compact-sized car in the late 80's. Three stages of the project leading to an optimised engine-turbocharger package are outlined. Achievement of Stage 1, leading to evaluation of

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 ...

Efficiency in Jet Fuel Markets

2023
Abstract: Jet fuel cost is an essential element of expenditure in the airline industry. Price has a significant influence on various industry decisions and their respective operations. Being a product derived from crude oil, prices are constantly fluctuating, volatile, and a challenge for future air travel decisions.

Ammonia as efficient fuel for SOFC

Journal of Power Sources, 2009
Abstract Ammonia is a possible candidate as the fuel for SOFCs. In this work, the influence on the performance of a tubular SOFC running on ammonia is studied. Analysis of open circuit voltages (OCVs) on the cell indicated the oxidation of ammonia within a SOFC is a two-stage process: decomposition of the inlet ammonia into nitrogen and hydrogen ...

A fuel-efficient geodynamo?

Nature, 2004
The hunt has been on for a source of extra power to account for the dynamo that generates the Earth's magnetic field. A synthesis of computation and experiment now suggests that the search may not be necessary after all.
