Carbon dioxide surface, warming the surface and the lower atmosphere. Less energy reaches the upper atmosphere, which is therefore cooler because of this absorption. Increases in atmospheric concentrations of and other long-lived greenhouse gases such as methane, nitrous oxide and ozone have correspondingly strengthened their absorption and emission of infrared radiation, causing the rise in average global temperature since the mid-20th century. Carbon dioxide is of greatest concern because it exerts a larger overall warming influence than all of these other gases combined and because it has a long atmospheric lifetime (hundreds to thousands of years). Not only do increasing carbon dioxide
Nitrous oxide fuel blend a "game changing" technology with the following characteristics: Recent work on the decomposition of nitrous oxide has raised concerns about the safety risks of mixing hydrocarbons with nitrous oxide. By adding hydrocarbons, the barrier to an explosive decomposition event is lowered significantly. Nitrous oxide fuel blend Nitrous Oxide Fuel Blend propellants are a class of liquid rocket propellants intended to replace hydrazine as the standard rocket fuel. The fuel and oxidizer are blended and stored; this is sometimes referred to as a "mixed monopropellant". Upon use, the propellant is heated or passed over a catalyst bed and the nitrous oxide
