MH's ideal coil and voltage question

[minnie]

  Kinetic energy. Flywheel.
  If you've got a decent sized flywheel it's not easy to get a spike.
  Forget about infinite energy in infinite time, just deal with the
  relatively short term.
  I have struggled because the whole thing isn't intuitive with the
  limited knowledge of inductors which I had.
  MH's. question was a hell of a good one, very thought provoking.

   Could well do.
   I think the speed of light would put a limit on infinity.

picture spinning the flywheel up using compressed air

That would be an accurate analogy of an ideal voltage source and inductor, if the flywheel could also push the compressed air back in.

Yes John,,

Now picture spinning the flywheel up using compressed air,, now picture slowing it back down using compressed air,, just reverse the direction of the air flow right?

The flywheel analogy makes it pretty damn easy to answer the question.  However, I have mentioned the flywheel analogy perhaps 30 times in the past, and I wasn't going to mention it again.  This time I switched to a shopping cart analogy, which is just as easy, but it did not hit home and apparently did not register.

Yes reversing the direction of the air flow is perfectly valid.  But you did not mention an important thing.  As the flywheel spins up in either direction, the speed of the air flow has to keep on increasing proportional to the speed of the flywheel.

Thanks John, but from my perspective this has still not reached a conclusion, and Brad still has not met the two milestones that I stated for him.  There is an intermediate question proposed by Partzman to consider which is very educational.  Then there is the issue of the second question that I answered right away that was "summarily dismissed" by Brad earlier in the thread as being wrong.

So does the thread die a miserable death, or does Brad try to see it through?

This thread has had the usual "barrel of monkeys" craziness.  Just look at the issue of the variable ideal voltage source.  We had Brad, Magluvin, Magneticitist, and Wattsup all insisting that it was "not permitted" because they read a definition online or in a book and couldn't think beyond what they read and use their noggins and show some creative thought.  Will any of them simply post and admit that they were wrong?

Anybody that cares to read this thread from the beginning will see how truly crazy and nonsensical it could get at times.  Does it die, or does Brad see it through?
