Compact fluorescent lamps and the Hippocrites

The fever that is inflicting us all the Global warming melody has the new religions preachers warning us of apocalyptic calamities unless the fever is abated by their science of alchemy and their cure of the 4 humors by bloodletting(aka taxation).The industry that will arise will see numbers of leeches(lawyers and politicians practicing their task with earnest.

Interestingly enough the first two horsemen of the apocalypse are the directors of the emission trading investment fund,are David BLOOD and Al GORE.

The traditionally held "Father of Medicine" was the Greek physician Hippocrates (460-370 BC), who taught medicine on the island of Cos. One of his major precepts was the rule of harmony, the theory that all body systems were in balance and that disease resulted from an imbalance. Galen (130-201 AD) was the physician to Marcus Aurelius and became the heir to Hippocrates and one of the most influential physicians of all times. He taught the importance of maintaining balance between the four bodily fluids, or "humors" blood, phlegm, yellow bile, and black bile. Each fluid was associated with a specific personality characteristic. Blood was associated with a sanguine personality, that is laughter, music, and a passionate disposition. Someone with a phlegmatic personality was sluggish and dull, while yellow bile represented an individual quick to anger or choleric (cholera meaning yellow as in yellow fever). Lastly, black bile represented a melancholic or depressed personality, melan meaning black. It was the job of the physician to restore harmony in those four humors by the use of emetics, cathartics, purgatives, and by bloodletting. Bleeding was used to reduce excess circulation, to slow the pulse, and to "reduce irritation", all felt to be the cause of inflammation.

Today we see the local shaman suggesting the mandatory use of Compact fluorescent lamps. Immediately this religious icon is told of producing miracles, saving mankind from the evils of co2 and the modernization of the last 150 years.

Unfortunately as with most cargo cult religions, miracles do not withstand the test of time. In this case 2 minutes. Knowing that fluorescence is a result of plasma physics I wondered what the spectral emissions were, and the properties of the chemical activator coatings.

1 CFLs contain trace amounts of mercury. The amount is not large enough to pose a hazard to users (it is about 1/5 the amount in a typical digital watch battery), but it does become a concern at landfills and trash incinerators where the mercury from many bulbs can escape and contribute to air and water pollution.

2 Here are two main parts in a CFL: the gas-filled tube (also called bulb or burner) and the magnetic or electronic ballast. Electrical energy in the form of an electrical current from the ballast flows through the gas, causing it to emit ultraviolet light. The ultraviolet light then excites a white phosphor coating on the inside of the tube. This coating emits visible light. CFLs that flicker when they start have magnetic ballasts; CFLs with electronic ballasts are now much more common.

Compact fluorescent light bulbs are widely considered an environmental solution to replace the ubiquitous incandescent light bulb. Yet few consumers are aware that compact flourescent bulbs have a noisy high voltage, high frequency circuit inside to trigger and maintain their glow. Since the operating frequency of these bulbs is below the AM radio band, there are no restrictions on the amount of electromagnetic radiation that they can generate. Manufacturers have strived to make the lowest cost bulbs using unshielded circuits that generate very high field levels. An example of a compact fluorescent bulb shows that the field strength within one inch of the bulb is an incredible 100mW/cm2

Uv exposure is yet to be quantified ,I suspect we can see mass outrage from the Greens and NGO, letters to the editor,the UNCERTAINTY PRINCIPLE cited by schoolteachers or is this just the HYPOCRISY of the religious left.
