[edit] Wok Qi
It would be interesting to elaborate on the topic of "Wok Qi". The subject does sound intriquing but I always thought the secret was to buy good (fresh) cooking oil and to wait a little longer for the oil to get a little hotter in the wok (without causing a kitchen fire of course).

Teflon non stick comments are erroneous and inappropriate.
Studies using FDA standard testing methods have found no detectable level of PFOA in Teflon® non-stick cookware.
PFOA (perfluorooctanoic acid), also known as C-8, is an essential processing aid used to make fluoropolymers--high performance plastics manufactured by a number of companies. PFOA is the carcinogenic (cancer-causing) element thought to be found in Teflon® brand non-stick coatings used for cooking.
A published, peer-reviewed study (April 2005) in Environmental Science & Technology found no PFOA in Teflon® cookware.
No PFOA was detected even when the cookware was scratched with a knife. Studies using FDA standard testing methods also found no detectable levels of PFOA in non-stick coatings used for cookware sold under the Teflon® brand. The Danish Technical Institute and China Academy of Inspection and Quarantine tested Teflon® cookware and did not detect PFOA.
Not all non-stick coatings are branded Teflon®.
Teflon® branded non-stick coatings are made solely by DuPont. Teflon® is a registered trademark. Temperature Safety Region for Cooking Products with Non-Stick Coatings
Significant decomposition of non-stick coatings will occur only when temperatures exceed about 660°F (349°C). The maximum temperature of the Cooking Master® heating element is 450°F (230°C), well below the non-stick coating safety threshold. In fact, the non-stick inner pot of the Cooking Master® will never reach more than 375°F (190°C).
