Hydrogen production technology for powering civil and industrial systems : a review
Partial use of alternative energy exemplified by hydrogen energy is expected to reduce negative impacts associated with the current dependence on fossil energy and bring net gain to regional and national economies. Hydrogen has emission levels that are far below the existing and possibly, future standards. Hydrogen energy may enhance energy security and perhaps allay concerns some concerns about global climatic change, environmental issues, energy efficiency, and infrastructure development. Since the production of hydrogen is energy-intensive, a production technique that negates this disadvantage with a high volume output within a reasonable time, is desirable.
ADVANCED UNDERGROUND VEHICLE POWER AND CONTROL FUELCELL MINE LOCOMOTIVE
A fuelcell powered locomotive, an underground mining haulage vehicle, was developed and is presently undergoing productivity field testing. Powered by proton-exchange membrane (PEM) fuelcell stacks, coupled with reversible metal-hydride storage, the four-ton locomotive has undergone safety risk assessment and preliminary performance evaluations at a surface rail site in Reno, Nevada. The powerplant, developed by project partner Sandia National Laboratories/CA, exhibits low parasitic power loss and low noise.
APPLICATION OF SATELLITE PHOTOGRAPHS IN A MORPHOTECTONIC STUDY OF THE CENTRAL ALBORZ, IRAN
This paper introduces a study of morphotectoni c structure in the Central Alborz Basin, Mazandaran province of Iran (about 1200 square kilometer), using Russian KFA-1000 satellite photography and sequential air photographs. The KFA-1000 metric camera has better ground resolution than SPOT and LANDSAT for the whole of the study area. Results are provided from one pair of 30×30 cm. photos, which provided easy interpretation and better results than other data. Areas identified from these images as being of significance were examined in greater detail through the use of aerial photographs (at scales of 1:5000, 1:10000 and 1:60000 were available).
