    A 2020 analysis revealed that DAC 2 technology may be an unsuitable option to capture the projected 30 Gt-CO2 per year as it requires an enormous amount of materials (16.3–27.8 Gt of NH3 and 3.3–5.6 Gt of EO) [33] The same study found that DAC 1 technology requires at least 8.4–13.1 TW-yr (46–71% TGES), an estimate that was calculated ...

    en.wikipedia.org/wiki/Aquascaping

    Aquascaping is the craft of arranging aquatic plants, as well as rocks, stones, cavework, or driftwood, in an aesthetically pleasing manner within an aquarium—in effect, gardening under water. Aquascape designs include a number of distinct styles, including the garden-like Dutch style and the Japanese-inspired nature style. [ 1 ]

    The Codd-neck bottle encloses a marble and a rubber washer/gasket in the neck. The bottles were filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation. The bottle was pinched into a special shape to provide a chamber into which the marble was pushed to open the bottle.

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    The carbon dioxide used to make synthetic fuels may be directly captured from the air, recycled from power plant flue exhaust gas or derived from carbonic acid in seawater. Common examples of synthetic fuels include ammonia and methane , [ 2 ] although more complex hydrocarbons such as gasoline and jet fuel [ 3 ] have also been successfully ...

    en.wikipedia.org/wiki/Soda_geyser

    A soda geyser is a physical reaction between a carbonated beverage, usually Diet Coke, and Mentos mints that causes the beverage to be expelled from its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.

    en.wikipedia.org/wiki/Carbon_dioxide_scrubber

    A carbon dioxide scrubber. A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2).It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight chambers.

  9. Calcium looping - Wikipedia

    en.wikipedia.org/wiki/Calcium_looping

    Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. [1] It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
