I have a question or two or three about a project I'm working on. Specifically about MHD generators and electrodes. Please post if you know something about these subjects and I'll ask the questions at the time probably via pm. Thanks

The presence of the Hall effect in MHD generators has led to the concept of ducts containing electrodes consisting of alternate conducting and insulating segments. In the vicinity of the segment junctions, losses by the Joule heating are very high, and particularly harmful in the case of gases with non-linear electrical conductivity. The use of semi-conducting electrodes should permit uniform operation inside the generator. Additional losses (in the semi-conducting material) are inevitable in any finitely-segmented generator using a gas with tensorial conductivity, but the paper shows that these are minimum in generators with semiconducting electrodes(See more).

That's the beauty of this forum. Ask and ye shall receive.
How is it you came by his question?, were you doing a search on the subject and it popped up in a search, or are you a regular lurker?

Either way, welcome to the forum Nathaniel.

Hmm.....that has nothing to do with what I am interested in but at least it's on topic. What is essay guardian and whose essay is this?
