Clusters of zinc atoms then mix with a reactive gas, usually oxygen, and cool to a solid.

Bolt comes with a trick-looking two-into-one exhaust system, which includes an oxygen sensor and exhaust gas catalyst that works with the closed-loop fuel injection system.

The hot gas breaks up the reactants into atoms of carbon, hydrogen, silicon and oxygen.

Nitrogen is separated from oxygen before combustion, thereby reducing the volume of exhaust gas and making the exhaust easier to treat by preventing the formation of polluting nitrogen oxides.

To keep turbine sales spinning, Immelt has turned to a process that partially burns pulverized coal in the presence of pure oxygen to turn it into a flammable gas that can drive linked gas and steam turbines.

In this configuration, the HTP is passed over a catalyst pack to decompose it into steam and oxygen, but instead of igniting a fuel grain, this superhot gas is allowed simply to vent through the chamber nozzle.

Too much oxygen and the toxic ammonia in waste won't convert to nitrogen gas, which bubbles out.

The gas is then fed into a stack of solid oxide fuel cells, where a chemical reaction between hydrogen and oxygen occurs, producing electricity, water vapor and a tiny amount of carbon dioxide.
