Re: Stellarators with Permanent Magnets

--- nowhere near to the response time of a superconductor. --- I wonder if there is any theoretical limit of the speed we might expect, if we test all the material choices ? But isn't a permanent magnet simply a type of room temperature superconductor to start with ? Now I'm wondering if there are m...

Re: Stellarators with Permanent Magnets

--- What we learned from nature so far is that to control any reaction you need to have a faster response time of the reaction itself. --- I wonder how the sun manages that trick ? Or is gravity helping out ? Does gravity have a fast response time I wonder ? I wonder if material choices effect the s...

Re: Stellarators with Permanent Magnets

--- permanent magnets have a reactive behavior so their response to reach a new equilibrium position is slower than a coiled superconductor --- I wonder if different permanent magnetic materials have different response times ? I might also wonder if different material superconductors also have diffe...

Re: Stellarators with Permanent Magnets

--- Firstly permanent magnets are not permanent as their flux energy will decrease over time --- I remember as a kid asking this question and being told they didn't decrease ! So nice to finally get a correct answer. Which begs a question, due to my interest in permanent magnetic gearing, how much f...

Re: Richard Nebel's Tibbar Plasma Technologies

Someone had this to say about his DC to DC work: --- Interestingly similar to the (old) CEGB''s magnetohydrodynamic generation project on which I worked in the '60s. That failed because of the difficulty in getting long-lived enough electrodes to extract anything like a useful electrical current fro...
