its ok ...
but i opened the message to see whether any conclusion has been reached...but i guess not yet...
It is theoretically possible to generate light from bio-degradable substances..
their are insects and fishes which do it... we need to understand their technology and then we will be able to get the eco friendly light without coal and reactors...
Essentially the light is generated using a chemical reaction in which photons play a vital role... energy level change is triggered with the absobtion of low frequency photons and light is visible with the emission of high frequency photons..
Certain Biological chemical substance have meta stable state which is more likely to be reached when a fall of energy level is triggered.
Lev1
Lev2
Lev3
From lev2 electrons reach to level1(using infra red photon absorbtion) and then it falls straight to lev3 generating visible light of high frequency...
Overall energy loss is covered up by agitaing the atoms in a particular fashion by the generated heat of the chemical reaction triggered by the 'food'eaten by the insect.
Cheers
