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. |
|
| |
Thanks. However, I'd sooner be the second person to
try it. |
|
| |
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. |

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. |
|
| |
// a cool way to lower someone into a grave. // |
|
| |
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. |
