In an age when technology has produced kilns capable of attaining high temperatures in a matter of hours, it is perhaps remarkable that many potters choose to build and fire kilns that are labor intensive and require constant attention throughout the entire period of the firing, which may last several days.
Based on these results, the CPC-type solar water heater system with a U-pipe shows superior thermal performance in attaining higher temperatures and has potential applications in space heating, heat-powered cooling, seawater desalination, industrial heating, and so on.
The gasifier could able to attain high temperatures in the range of 976 1100 °C with gas lower heating value (LHV) and peak cold gas efficiency (CGE) of 7.86 MJ/Nm3 and 87.6% respectively.
The performance of the ultra-high-temperature furnace using graphite heater was examined to attain high temperatures above 2500 oC by using a system having the electric power supply with 30 kW maximum and in various atmospherics, vacuum, Ar, He, N2 and their mixtures.
The use of a solar furnace as an environmentally friendly means to attain high temperatures for application to nitrogen fixation is an interesting concept.
It is teleologically reasonable to hypothesize that this trait is likely to be acquired by yeasts growing on fruit, which attain high temperatures during decomposition.
Stationary solar concentrators can be integrated with building façade and roof, which can reduce the area of solar cells and attain higher temperature heat resource, especially in winter for building application.
Those eggs shaded by vegetation (25° C [77° F]) yield males, and those laid under open sand attain higher temperatures (30° C [86° F]) and yield females.
For frictional heating of 200°C to 250°C, slip displacement of more than 15 m is required at shallow depths (e.g., 200 m), whereas a shorter displacement of <10 m would attain higher temperatures at greater depth (e.g., 600 m).
The composite films with 5.0 10.0 wt% MWCNT contents, which had sufficiently low electrical resistivity of ∼103 100 Ω cm, exhibited excellent electric heating performance by attaining high maximum temperatures as well as electric energy efficiency.
The common solar water heater system can meet low temperature requirements, but exhibits very low efficiency in attaining higher water temperatures (55 95 °C).
