Methane Plus Oxygen Yields Carbon Dioxide and Water

Visualized here is  a chemical reaction, the burning of a molecule of methane.   These  are made with an organic chemistry model kit,  wherein the elements carbon, oxygen, and hydrogen are represented by the black spheres,  red spheres,  and white spheres, respectively.

DSC00729 One methane molecule,  CH4, which is an atom of carbon bonded with four atoms on hydrogen, reacts with two molecules of oxygen (O2),  each of which consists of two atoms of oxygen bonded together,DSC00728

rearranges the atoms to yield one molecule of carbon dioxide (CO2), and two molecules of water (H2O).

People (scientists of different types, e.g. chemists, physicists, climatologists) study interactions of these molecules in the atmosphere.   Methane, carbon dioxide, and water are all greenhouse gases in order of decreasing strength per molecule.

 

Plantains May 28, 2014

DSC02750 Some of those frozen dead plantain stems are being overtaken by their living cores, leaving dry, tan  debris hanging underneath the newly sprouting green tops.  I wish I had cut out more of the dead stems while they were not covered up by living leaves, but am glad for what I did get done.   The plantains grow from the center out, and the centers of some of the thicker ones survived, and have begun growing.   Also those corms which had formed underground are now sprouting.

In addition to the dead stems, I will cut out the tallest plantains soon which are located in the patch in the back and on the right,  and thereby reduce the garden shade a bit in the coming months, though plantains are not the only source of shade for the vegetable garden.   The houses, other trees, and other vegetation contribute to shade. I am way behind in making compost and mulch out of the  plantain leaves and stems, but I am confident that  both are high quality, the result of fixed and held carbon dioxide and other nutrients.

We will not have many plantains this year because it takes at least 15 months for them to bear fruit.  Next year we should have many again, if we are spared a freeze in the coming winter.

As I learn, I am rethinking the emphasis that this garden should take.   When I saw plantains in the store last week they were $0.60 +  each, I realized that plantains are by far our most  monetarily rewarding  and dependable crop, and aside from the patch grooming, require no effort  or cash input on our part.   Our garden emphasis will surely change year by year.
