The Climatron is a greenhouse enclosed in a geodesic dome that is part of the Missouri Botanical Garden in St. Louis. Initiated by then Garden director Frits W. Went , the dome is the world's first completely air-conditioned greenhouse and the first geodesic dome to be enclosed in rigid Plexiglass (Perspex) panels.
The engine has near isothermal cylinders because 1) the heater area covers the entire cylinder end, 2) it is a short stroke device, with wide shallow cylinders, yielding a high surface area to volume ratio, 3) the average thickness of the gas space is about 0.1 cm, and 4) the working fluid is Helium, a gas having good thermal properties for Stirling engines.
The terms greenhouse, glasshouse, and hothouse are often used interchangeably to refer to buildings used for cultivating plants. The specific term used depends on the material and heating system used in the building. Nowadays, greenhouses are more commonly constructed with a variety of materials, such as wood and polyethylene plastic. [2]
Note the important factor of 2, resulting from the fact that the atmosphere radiates both upward and downward. Thus the ratio of T a to T s is independent of ε: = = Thus T a can be expressed in terms of T s, and a solution is obtained for T s in terms of the model input parameters:
An exact calculation using the MODTRAN model, over all wavelengths and including methane and ozone greenhouse gasses, as shown in the plot above, gives, for tropical latitudes, an outgoing flux = 298.645 W/m 2 for current CO 2 levels and = 295.286 W/m 2 after CO 2 doubling, i.e. a radiative forcing of 1.1%, under clear sky conditions, as well ...
The industrial era growth in atmospheric CO 2-equivalent gas concentrations since 1750 [32] Starting about 1750, industrial activity powered by fossil fuels began to significantly increase the concentration of carbon dioxide and other greenhouse gases.
Emissions attributed to specific power stations around the world, color-coded by type of fuel used at the station. Lower half focuses on Europe and Asia [1]. This article is a list of locations and entities by greenhouse gas emissions, i.e. the greenhouse gas emissions from companies, activities, and countries on Earth which cause climate change.
Trimethylglycine is an amino acid derivative with the formula (CH 3) 3 N + CH 2 CO − 2.A colorless, water-soluble solid, it occurs in plants. [5] Trimethylglycine is a zwitterion: the molecule contains both a quaternary ammonium group and a carboxylate group.
