Lenz's Effect Mine Shaft Slow Motion Bungee Descent

wear magnets and jump down that hole
  [vote for,

Lenz's Effect Mine Shaft Slow Motion Bungee Descent allows a very sedate descent to be experienced, and is a variation on the standard Mine Shaft Bungee Jump.

In the Lenz's effect variation, the mine shaft has been lined with copper from top to bottom. The bungee jumper now dons a special suit completely covered with Neodymium Magnets. The subsequent descent now takes place in total slow mo as Lenz's Law effect retards the downward progress of the traveller to that of a gentle airborne stroll.

       Now, this is something I can vote for.

       Created just for you....
xenzag, Jul 25 2015

       Thanks. However, I'd sooner be the second person to try it.
MaxwellBuchanan, Jul 25 2015

       Probably best sited in Germany, many unused mines (wikipedia) "Upper Harz...shaft depths of 1,000 metres were reached.."   

       Incorporation in that country would enable funding, possibly using the "Community Organisation" nomenclature.   

       NB Top point for .."Mining operations continued in Bad Grund, however, until 1992." Ok, it's not quite up "The Diet of Worms", but our Teutonic cousins do seem to have some sense of humour.

       Thank you...... small voice coming up from bottom of mine shaft as heavy copper sheeting is installed.

       Good grief! Congratulations!

       Oops, I went to edit my comment to fix a typo and accidentally deleted the whole comment.   

       The deleted comment was:   

       I just noticed you've surpassed the 1,000 idea mark (currently at 1,014 if my idea counter view is correct). Probably the first halfbaker to do so (Although UnaBubba possibly did before he nuked his account). Well done.

       I wonder if the inverse of this would work?   

       If you drop a block of copper down a tube lined with magnets, will it also fall slowly?   

       More to the point, the human body is somewhat conductive. So, is there a magnetic field strong enough to significantly slow the fall of a human? If so, I suspect that the necessary eddy currents generated in the body would be lethal; but it would be a cool way to lower someone into a grave.

       So the eddy currents are high enough to interfere with the heart's PQRST . Why aren't we using magnetic heart massage then?.   

       If the magnetism effects the brain, all you are going to see are white rabbits.

       Ahhh ... why not use the Meissner effect, then?

       I am fairly sure that there is no temperature at which a corpse becomes superconducting. I suppose it could be done if they had some really large mercury amalgam fillings, but being lowered vertically, suspended by one's teeth, is not a dignified way to exit.

       By my understanding of the effect: yes, but the block would get very hot over the sort of distances we're talking about.
