EDIT: Nevermind my correction, I misread. ------ I had an idea to produce room-temperature superconductivity, but I haven't been able to find any similar research so I've largely dismissed it as a crazy idea borne out of ignorance of the finer details of electrical engineering and/or physics. One day, I'll probably set up an experiment to test my idea, and if it works, probably just drop it into a blog post and submit it to HN (where it will fade into obscurity like most of the articles under the "new" link). And if it doesn't, it will be a good cautionary tale for anyone with the same wrong idea about how the world works.

20K is -253c conversion from K to C is quite simple just 273(.15) from C to K or subtract it from K to C :P As far as temperature goes we don't need room temperature we need it to be high enough to be able to get to those temperatures efficiently (e.g. phase cooling) which can then be applied easily to large scale computing systems. With Optic-On-Chip/PIC becoming a plausible reality it's also might be possible to use laser based cooling within the silicon it self to get certain parts of it cold enough to introduce superconductivity but again every single degree (kelvin or otherwise) counts because the implications on the power required to cool the components down and keep them cool are enormous. The problem with very low temperature and very small components isn't even necessarily the energy if we are talking about the same component size and current and emerging silicon then with ~0-20K a stray high energy photon or any other type of cosmic radiation might be enough to knock your "gates" out of order if they are using some superconductive elements since we are already getting to the point of gates being atoms in size at least in some dimension.

That's awesome. It seems like you'd need a pretty good knowledge of the physics to even come up with an idea. I'd love to hear about it if you want to shoot me an email. I actually have a similar thing where it seems like I've got an idea for a better battery but I have to assume I'm just missing some basic physics.

  I sent you the gist of it in an email. It's not really that clever, nor something that a typical AA undergrad wouldn't be able to come up with. Hence, I don't put a lot of stock into my own idea. But if it just so happens to work, that'd be hilarious.
