This is a list of emerging technologies, which are in-development technical innovations that have significant potential in their applications. The criteria for this list is that the technology must: Exist in some way; purely hypothetical technologies cannot be considered emerging and should be covered in the list of hypothetical technologies ...
Heat is lost from the body in proportion to the amount of exposed skin. [288] [289] The head accounts for around 7–9% of the body's surface, and studies have shown that having one's head submerged in cold water only causes a person to lose 10% more heat overall. [290] [medical citation needed]
A microwave oven uses dielectric heating to cook food.. Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. [1] The word technology can also mean the products resulting from such efforts, [2] [3] including both tangible tools such as utensils or machines, and intangible ones such as software.
Omni Processor pilot plant by Sedron Technologies treating fecal sludge in Dakar, Senegal. Omni processor is a term coined in 2012 by staff of the Water, Sanitation, Hygiene Program of the Bill & Melinda Gates Foundation [1] to describe a range of physical, biological or chemical treatments to remove pathogens from human-generated fecal sludge, while simultaneously creating commercially ...
Thermal treatment is any waste treatment technology that involves high temperatures in the processing of the waste feedstock. Commonly this involves the combustion of waste materials. [1] Systems that are generally considered to be thermal treatment include: Cement kiln; Gasification; Incineration; Mechanical heat treatment; Pyrolysis; Thermal ...

The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...
