Sorry. I forgot to add that. On the other hand I think that material science will have the answer to this sooner or later. It will be really hard to make substances that can resist getting demagnitized due to jiggly-jiggly motions#, but maybe someone will come up with a way to make a crystal of domains that can stick together under extreme conditions. By the way, there is another design possibility over here the piston can be the coil and casing can be a liquid cooled magnet. We could transfer the current using graphite, or something. However, I doubt that the cost vs. benefit scenario will be on our side. Thanks for correcting me! # Yes, that's a technical term :) [edit: I don't know if it is out of line, but a post you wrote (http://jacquesmattheij.com/content/adhd-ritalin-and-evolution http://jacquesmattheij.com/content/adhd-ritalin-and-evolutio...) nearly drove me to tears. You are an amazing father and human being. I just wanted to thank you on your son's behalf.]
