Green Tea and Caffeine. Naturally-occurring caffeine in tea is removed by any of four decaffeination processes. Two use the chemical solvents ethyl acetate and methylene chloride, one uses carbon dioxide and one uses water. None of these result in tea that is totally caffeine free; by law, a label that displays decaffeinated must have at least 97 percent of the caffeine removed.
Later that was ret-conned, and Sifo-Dyas became a separate entity from Sidious and was a Jedi who had been manipulated by Sidious through his friend Dooku to order the Clone army. Later he was killed in a duel with Count Dooku who then preserved the body and kept his lightsaber.
Obi Wan is clearly the most powerful jedi. He killed Darth Maul as a PADAWAN. He then took care of Grievous when others failed. He was able to seriously maim the 2nd most powerful jedi on this list. He trained Luke Skywalker, who in turn, was able to turn Anakin back to the light side.He also was one of the few who survived the purge. If he is not the most powerful jedi, then I don't know who is. Obi-wan took out Darth Maul, one of the most skilled light-saber duelists of all time, while he was still a padewan.He killed Grievous, another skilled duelist.lso in episode III it was Anakin who pretty much embarassed Dooku while Obi wan was unconscious. Anakin Would of been the most powerful but never reached his full potential and should be 2 on this list to Luke who is one because he did reach his full potential.
