Описание:In a HPR vessel, the material properties and the inner matrix structure are two critical design parameters that determine the hydrogen mass efficiency. The bubbles are arranged within a solid mass similar to a foam-like structure. HPR vessels are safer than cylindrical pressure vessels, potential for higher mass efficiencies and can assume confirmable vessel shapes to fit within available space. The focus of this study is devoted to investigating the performance characteristics of one configuration; spherically shaped bubbles homogenously arranged in a simple cubic inner matrix packing structure for a HPR vessel, using Finite Element Analysis. A HPR vessel involves compressing hydrogen gas within small spherical bubbles. Efficient and innovative method of hydrogen storage for automotive fuel cell application is to compress hydrogen in minute hollow spherical bubbles incorporating the Hydrostatic Pressure Retainment (HPR) technology. By compressing the gas within the small bubbles, a near- hydrostatic (tri-axial) tension is induced in the structural material between the adjacent bubbles.

Guns, Germs, and Steel: The Fates of Human Societies

For instance, the stone sickles, underground storage pits, and other technology that hunter-gatherers of the Fertile Crescent had HEMISPHERESCOLLIDING • 365 been evolving to utilize wild cereals were available to the first cereal farmers of the Fertile Crescent. In contrast, the first settlers of the Americas arrived in Alaska with equipment appropriate to the Siberian Arctic tundra. They had to invent for themselves the equipment suitable to each new habitat they encountered. That technology lag may have contributed significantly to the delay in Native American developments. An even more obvious factor behind the delay was the wild animals and plants available for domestication. As I discussed in Chapter 6, when hunter-gatherers adopt food production, it is not because they foresee the potential benefits awaiting their remote descendants but because incipient food production begins to offer advantages over the hunter-gatherer lifestyle. Early food production was less competitive with hunting-gathering in the Americas than in the Fertile Crescent or China, partly owing to the Americas' virtual lack of domesticable wild mammals ...»
