Hey, on that other topic: This is just astounding! And scary.

But back to Teflon, for my wife, who is allergic to nickel, I'd have to suggest Teflon as a prosthetic. Titanium has better biocompatibility than stainless, but still has the "cartilage" part using Teflon.
As you use all that hot water to scrub, scrub, scrub: it's heated how, exactly? :-) Even the environmentally "friendly" soaps are using caustics to formulate the mixture (using electricity and other resources). Where is the oil coming from? Vegetables, cows, sheep or petroleum? All of those have impact. I would find the calculus of the various sources really hard to extract.
I was out with my friend this weekend speculating about how many POUNDS of oil was used to fabricate my digital camera which only uses rechargeable batteries now (better watch how I dispose of those!). All that energy to melt the glass, refine the semiconductors, melt the aluminum, run the lathes, etc. Probably 30-40 pounds (maybe more, methinks). For a computer, it might be 5 to 10 times that of my camera.
Hard to be a creature on the planet and have NO foot print. Dying cows and melting glaciers are a warning sign. |
