A Geothermal Energy Hawaii - pros vs. cons
#28
Bullwinkle I can appreciate your concern about molecular poisons and radioactive isotopes.

I would like to point out that a molecular poison such as Hydrogen Sulfide are not comparable in regard to general concentration build ups released into the environment to that of radioactive isotopes.

Hydrogen Sulfide is subject to the chemical reactions it will encounter upon release into the environment and therefore succumb to disassociation or become a building block in a larger molecule. Hydrogen Sulfide has been created and released into the environment since the dawn of the earths existence. Hydrogen Sulfide is also produced and used within your body as a signaling molecule as clearly noted in the Wiki link I post above.

On the other hand, radioactive isotopes released into the environment are a serious problem, with half lives in the millions and billions of years. They will continue to pose a threat to all forms of life long after their release into the environment and their concentration level do build up because of their long half life period and relative rate of release into the environment.
