Without photosynthesis nothing would live on the planet. Universal qi would still exist, but planetary qi would not because it is the activity of life. Cold air is denser and its molecules move more slowly. Warm air's molecules move faster and carry heat around a room, moving more rapidly the hotter they get. That cold spot people sometimes feel in houses is our bodies' reaction to this function of convection.
Winds are planet-sized convection currents set in movement by Earth's spin.
Ancient sources tell us that planetary qi is dispersed by wind, so it seems that convection and qi do not necessarily coexist. Because these are our basis for remedies to homes and environments, let's look at how electromagnetism can be interpreted within Five Element Theory. Everyone knows that the Earth is used as a ground in electricity. The Earth Element's associative color is yellow, which falls into the pure spectral range of 5770 to 5970 angstroms. If we include orange, the range jumps from 5770 to 6220 angstroms.
