Solar-driven water desalination technologies are rapidly developing with various links to other renewable sources. However, the efficiency of such systems severely depends on the design parameters.

Metrics details. The main drawback of passive solar still is its lower efficiency and distillation output. Different designs of passive solar stills are fabricated and tested by various researchers to meet water demand economically. Concave wick basin pyramidal-shaped solar still was observed to produce 4.

A new method is demonstrated for fabricating TiO 2 nanoparticles. The size of the formed TiO 2 nanoparticles depends on the fluorine concentration and can be controlled from 20 to nm. The crystal properties of nanoparticle layers are superior compared to those of nanotube arrays.

Experimental Study on Various Solar Still Designs

Arunkumar, K. Vinothkumar, Amimul Ahsan, R. Chennai , India. Box-5, Muzaffarpur , India. Humankind has depended for ages on underground water reservoirs for its fresh water needs. But these sources do not always prove to be useful due to the presence of excessive salinity in the water. In this paper, the fabrication of seven solar still designs such as spherical solar still, pyramid solar still, hemispherical solar still, double basin glass solar still, concentrator coupled single slope solar still, tubular solar still and tubular solar still coupled with pyramid solar still and their performance evaluation in converting brackish water into fresh water for drinking are presented.

Distilled water is needed for drinking, irrigation and for many other applications. A diversity of approaches are used for these portions of fresh water from saline water; namely multi stage flash MSF , multiple effect ME , reverse osmosis RO , electro dialysis, ion exchange, phase change, and solvent extraction. These methods are expensive, however, for the production of small amount of fresh water. The development of solar distillation has demonstrated its suitability for the desalination process when the weather conditions are suitable and the demand is not too large, i. The problem of low daily productivity of the solar stills triggered scientists to investigate various means of improving the stills productivity and thermal efficiency. Different aspects of triangular-shaped solar stills CSS , also called double slope stills, have been studied. Production in this still is influenced by the orientation, as shown by Singh et al.

Ziggurat Pyramid is a pyramid-shaped arcology that was conceived for Dubai in It was estimated to start construction in and complete it by The structure was designed to house nearly one million people and would be self-sustainable with all-natural energy sources. Like the pyramids of the Mayans and Egyptians , this structure in Dubai would be a giant; it would cover 2.

Background

 В куполе нет света. - У тебя галлюцинации. Тебе пора отправляться домой.  - Он перевел взгляд на схему. - Там темно как в преисподней! - закричала. Джабба вздохнул и положил фонарик рядом с. - Мидж, во-первых, там есть резервное электроснабжение.

Неужели ему предстояло погибнуть по той же причине. Человек неумолимо приближался по крутой дорожке. Вокруг Беккера не было ничего, кроме стен. По сторонам, правда, находились железные ворота, но звать на помощь уже поздно. Беккер прижался к стене спиной, внезапно ощутив все камушки под подошвами, все бугорки штукатурки на стене, впившиеся в спину. Мысли его перенеслись назад, в детство.

При этом внезапное отключение электроснабжения не прерывало работу ТРАНСТЕКСТА и его фреоновой системы охлаждения. Если бы этого не было, температура от трех миллионов работающих процессоров поднялась бы до недопустимого уровня - скорее всего силиконовые чипы воспламенились бы и расплавились. Поэтому такая перспектива даже не обсуждалась. Сьюзан старалась сохранять самообладание.
