Wind power in Texas grew very rapidly, 2400% from 1999 to 2007. In another large state, California, wind generation increased by 48% in the same period. [7] The cost of wind power generation has decreased by about 80% over the last 20 years because of technological advances and is now cost-competitive with other energy sources.
Liquid nitrogen (LN 2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air .
A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...
CF Industries Holdings, Inc. is an American manufacturer and distributor of agricultural fertilizers, including ammonia, urea, and ammonium nitrate products. The company is based in Northbrook, Illinois, a suburb of Chicago, [3] and was founded in 1946 as the Central Farmers Fertilizer Company.
Over the next 70 years, Texas Farm Bureau grew from 15,630 member families to more than 500,000 member families. [7] During its history, the organization has helped bring electricity and phone service to rural communities, establish a successful farm-to-market road system in Texas and enact effective national farm policy.

The state record for the largest fish kill occurred in 2001, when a fertilizer spill killed nearly 1.3 million fish. Will killing 500,000 owls help similar species? Groups slam ‘reckless ...
Although nitrogen makes up most of the atmosphere, it is in a form that is unavailable to plants. Nitrogen is the most important fertilizer since nitrogen is present in proteins (amide bonds between amino acids), DNA (puric and pyrimidic bases), and other components (e.g., tetrapyrrolic heme in chlorophyll). To be nutritious to plants, nitrogen ...
Although the liquid nitrogen is colder than the ambient temperature, the liquid nitrogen engine is nevertheless an example of a heat engine.A heat engine runs by extracting thermal energy from the temperature difference between a hot and a cold reservoir; in the case of the liquid nitrogen engine, the "hot" reservoir is the air in the ambient ("room temperature") surroundings, which is used to ...
