Q. How can anyone survive a dive of over
5,000 feet? A. By entering the water
very slowly and carefully.
Q. How is that going to be
possible?
A.
By using the apparatus which forms the
essential components of the Mile High
Diving Tower.
I should explain... the pool of water is
positioned 40 feet below the diver at the
top of the tower. As soon as the diver
begins his/her plunge towards the pool,
it
begins its own descent, travelling at a
speed calculated to ensure that they
break
the surface of the water very slowly, this
action being recorded on camera and
projected unto large screens for the
benefit
of
a watching audience.
Once the diver has fully entered the
water,
the entire pool, complete with diver now
happily swimming around, begins to
decelerate, until it safely reaches the
ground.
20 Kilometers straight down, plus a relatively slow descent!

How high is the highest high diving board?

The tallest tower, even the highest mountain cliff drop, is less than half that height. But see the [Link]. |
|
| |
The entire “pool area” needs to be enclosed, to protect the diver and the water from air turbulence. To save on construction time, the diver could do this stunt inside an aircraft. |
|

//the highest mountain cliff drop, is less than half that height.// El Capitan in Yosemite is rather more like three quarters of that height.
I think Half Dome may be even higher. |

Would a large enough volume of water enable a diver to survive if it and he landed at terminal velocity?
I mean an extremely tall cylinder of water which would decelerate on impact as each new section of the cylinder burst apart and absorbed energy. |

Hmm. Let's check some numbers (in metric, since it's easier.) |
|
| |
Let's say a kilometer instead of a mile; and a swimming pool of 1/4 Olympic size (61,000 litres) ignoring the container. |
|
| |
Potential Energy = mgh, so getting the pool up a km will take (61000 x 9.8 x 1000) ~= 600 MJ. Since a km is about 0.6 miles, a mile will take a nice round Gigajoule. Should be doable, but it's gonna take some mighty big shock absorbers to dissipate this on the way down. |
|
| |
Maybe this should be done with electro-hydraulic pump / turbines, to regain some of the energy on the way down. |
|
| |
I wonder if there isn't another way to do this. One of the explanations for some of the disappearances in the Bermuda Triangle was methane outgasing which bubbles up through the water and lowers it's density to the point that ships won't float on it. I wonder if this same effect could work here to soften the water enough to allow for a safe landing. I know the Mythbusters tested this on boats. |

Hold on why don't they just do it in say a large elevator shaft , but you get sort of rings of fans like indoor sky diving experiences to decelerate the diver? . |
