Green Pressure Cookers ?!?

I look at a lot of green and "green" shite. I greatly enjoy hearing new applications for retro tech that is eco-chic now that one can claim being frugal is evergreen. This pressure cooking article is a great example. I use to be scared of em a'cause of a story my gramma told me. Now I have em on my great green radar screen, im cruising consumer reports for the best value.. and I am going to reel one in. Thank you UK Telegraph.
