Human behavior could be modified using light preferably real sunlight. A person could rest in a hammock while a large fan would rotate at a prescribed speed. For instance a fan blade would block the sun as it passes the individual. A four bladed fan spinning at 2 revolutions per second would produce a shade spot on the individual 8 times per second. What this would be attempting is to use the sunlight healing properties along with inducing Alpha brain waves to a frequency near the earth's frequency, which is 7.89 Hz.
The theory would hold that the immune system would run at full optimum around 8.5 Hz or right near the Earth's Resonance. The theory further holds that this is how our body works thru hundreds of thousands of years of evolution. Some additional theories which have been extrapolated from recent research claim that the sunlight is encoded and interacts with our DNA causing and triggering certain reactions allowing health healing releases in the brain and body. The theorists of such go so far as to say this either proves intelligent design or an ultra long period of evolution of the human species allowing us to adapt to the sun's rays in such a favorable way.
Still none of this has been proven, but I would like to see an attempt to use my simple idea of a fan to test these theories using real sunlight instead of the Alpha Brain Wave Therapy Machines, which use light bulbs and artificial light.
