This can be accomplished with a simple homemade system (using a bottle filled with yeast, warm water, and sugar, connected to an airstone in the aquarium), or, more commonly, with a pressurized CO 2 tank that diffuses a set amount of carbon dioxide into the aquarium water.
Outbreaks can be reduced by operating multiple independent systems with the same building and isolating water to water contact between systems by cleaning equipment and personnel that move between systems. [15] Also the use of an Ultraviolet (UV) or ozone water treatment system reduces the number of free floating virus and bacteria in the ...
A carbon dioxide generator or CO 2 generator is a machine used to enhance carbon dioxide levels in order to promote plant growth in greenhouses or other enclosed areas. [1] [2] Carbon dioxide generators have been used to help grow marijuana. [3] [4] They can be fueled with propane or natural gas.
The Allam-Fetvedt Cycle is a recuperated, high-pressure, Brayton cycle employing a transcritical CO 2 working fluid with an oxy-fuel combustion regime. This cycle begins by burning a gaseous fuel with oxygen and a hot, high-pressure, recycled supercritical CO 2 working fluid in a combustor.
Increased atmospheric carbon dioxide has been found to reduce plant water use, and consequently, the uptake of nitrogen, so particularly benefiting crop yields in arid regions. [10] The carbohydrate content of crops is increased from photosynthesis, but protein content is reduced due to lower nitrogen uptake.

Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]
Canadian manufacturer WhiteWater developed the world's only looping water slide, known as the AquaLoop. [2] There are nearly 20 AquaLoop installations around the world. [3]The first installation was at Terme 3000 water park, Slovenia in 2008. [4]
