Carbon offset production flows to regions or industries that have a lower price of carbon—unless carbon can be purchased from that area, which offsets effectively permit, equalizing the price. Carbon offsets may represent six primary categories of greenhouse gases: carbon dioxide (), methane (CH), nitrous oxide (NO), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and sulfur hexafluoride (SF). Carbon offsets have several common features: In 2009, 8.2 billion metric tons of carbon dioxide equivalent changed hands worldwide, up 68 per cent from 2008, according to the study by carbon-market research firm Point Carbon, of Washington and Oslo. But at EUR94 billion, or about $135 billion,
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
