Britton Stephens, an NCAR scientist and the project's co-principal investigator, said HIPPO flights have collected the first large - scale measurements of carbon dioxide and oxygen cycling into and out of surface waters of the Southern Ocean.

Two - way fuel cells Meanwhile, Versa, a solid oxide fuel cell stack supplier, is working with Boeing and «a large European company» on an innovative reversible SOFC that cycles back and forth between providing power and electrolyzing water into hydrogen and oxygen, Stokes says.

In addition, a supercritical turbine could fit into a directly heated cycle, where a fuel like natural gas burns in the presence of pure oxygen inside the turbine, creating only water and carbon dioxide as waste.

The early tetrapods (from the Ancient Greek word meaning «four - footed») were the first vertebrates to tread terra firma, developing lungs to capture atmospheric oxygen and turning fins into legs, but with a life cycle that was still closely tied to aquatic environments.

The researchers inserted tiny gas sensors into the tracheae of the pupae and monitored the relative amounts of oxygen and carbon dioxide during normal breathing cycles.

So when water vapor that has cycled through the Martian atmosphere condenses into the Martian soil, it can interact with and exchange oxygen isotopes with zircons in the soil, effectively writing a climate record into the rocks.

(Though, since that first episode covered primarily the oxygen cycle, diatoms and algae blooms were just mentioned as the source of half of the oxygen we breathe, as opposed to rainforests, which are important for the rain cycle that gets nutrients from the mountains into the oceans but which are using up all the oxygen they produce.

There is something so virtuous about a cycle that turns cement plant exhaust gases into oxygen and biofuel.

But pollution also covers hundreds of chemicals which are fine or even beneficial at low levels but which if released in large quantities or in problematic circumstances cause «harm» — like phosphorus (grows your veges but also leads to toxic cyanobacterial blooms which kill cattle), nitrogen (grows crops kills many native species of plants and promotes weed growth costing farmers), copper (used as an oxygen carrier by gastropods but in high concentrations kills the life in sediments which feed fish), hormones like oestrogen (essential for regulating bodies but in high concentrations confuse reproductive cycles especially with marine life) or maybe molasses from a sugar mill (good for rum but when dumped into east coast estuaries used to cause oxygen sag in estuaries leading to massive fish kills).
