Bodum Santos
A vacuum coffee maker brews coffee using two chambers where vapor pressure and gravity produce coffee. This type of coffee maker is also known as ''vac pot'', ''siphon'' or ''syphon coffee maker,'' and was invented by Loeff of Berlin in the 1830s. History and design Since their invention, these devices have since been used in many parts of the world. While vacuum coffee makers generally were excessively complex for everyday use, they were prized for producing a clear brew, and were quite popular until the middle of the twentieth century. Vacuum coffee makers remain popular in some parts of Asia, including Japan and Taiwan. Design and composition of the vacuum coffee maker varies. The chamber material is borosilicate glass, metal, or plastic, and the filter can be either a glass rod or a screen made of metal, cloth, paper, or nylon. The Napier Vacuum Machine by James Robert Napier, presented in 1840, was an early example of the vacuum brewing process. The Bauhaus interpretati ...

Moka Pot
The moka pot is a stove-top or electric coffee maker that brews coffee by passing hot water driven by vapor pressure and Charles's law, heat-driven gas expansion through ground coffee. Named after the Yemeni city of Mocha, Yemen, Mocha, it was popularized by Italian people, Italian aluminum vendor Alfonso Bialetti and his son Renato starting from 1933. It quickly became one of the staples of Culture of Italy, Italian culture. Bialetti, Bialetti Industries continues to produce the original model under the trade name "Moka Express". Spreading from Italy, the moka pot is today most commonly used in Europe, Latin America, and Australia. It has become an iconic design, displayed in modern industrial art and design museums including the Wolfsonian-FIU, the Cooper–Hewitt, National Design Museum, the Design Museum, the Science Museum (London), London Science Museum, Smithsonian Institution, The Smithsonian and the Museum of Modern Art. Moka pots come in different sizes, making from on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum
A vacuum (: vacuums or vacua) is space devoid of matter. The word is derived from the Latin adjective (neuter ) meaning "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressur ...

Coffee Preparation
Coffee preparation is the making of liquid coffee using coffee beans. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be coffee roasting, roasted, the roasted coffee beans must then be coffee grinder, ground, and the ground coffee must then be mixed with hot or cold water (depending on the method of brewing) for a specific time (brewed coffee, brewed), the liquid coffee extraction must be separated from the used coffee grounds, used grounds, and finally, if desired, the extracted coffee is combined with other elements of the desired beverage, such as sweeteners, dairy products, dairy alternatives, or toppings (such as shaved chocolate). Coffee is usually brewed hot, at close to the boiling point of water, immediately before drinking, yielding a hot beverage capable of scalding if splashed or spilled; if not consumed promptly, coffee is often sealed into a vacuum flask or insulated ...

Bodum
Bodum, Inc. is a Danish-Swiss kitchenware manufacturer headquartered in Triengen, Switzerland. Founded in Copenhagen, Denmark, in 1944 by Peter Bodum, the company was moved to Switzerland in 1978 by his son, Jørgen, who continued to run the company as chief executive. Among the products Bodum markets are French presses, vacuum coffee brewers (the " Santos" and " Pebo"), and double-walled beverage glasses made in China of borosilicate glass. Their products are advertised as BPA free. The company has tried to register "French Press" as a trademark in several territories, but failed in the U.S., and had the trademark expunged in Canada in December 2012. Bodum entered into a partnership agreement with American coffee company Starbucks in November 2016 to sell their French presses. In January 2019, the partnership agreement ended as Starbucks recalled defective presses. Their kitchenware featured on the set of Star Trek: The Next Generation, most notably a glass mug with black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minto Wheel
The Minto wheel is a heat engine named after Wally Minto. The engine consists of a set of sealed chambers arranged in a circle, with each chamber connected to the chamber opposite it. One chamber in each connected pair is filled with a liquid with a low boiling point (propane (''TB'' = −42 °C) and R-12 (''TB'' = −29.8 °C) are listed in the Mother Earth News articles). Ideally, the working fluid also has a high vapor pressure and density. Operation As the lower chamber in each pair is heated, the liquid begins to vaporize, forcing the remaining liquid to travel to the upper chamber. This fluid transfer causes a weight imbalance, which causes the wheel to rotate. Minto's pamphlet also suggests obtaining a pressure differential with a dissolved gas instead of a boiling gas. Soda water or propane dissolved in kerosene are suggested. Characteristics The Minto wheel operates on a small temperature gradient, and produces a large amount of torque, but at very l ...
