Green Skiing

[Brewski]

You probably thought this was another Radar post....LOL Saw this on FB from Lake Lessons in Austin, Texas. One way of going green. Now to get the slalom course to go down stream........

[Brewski]

gotta do that on a kneeboard or tricks, maybe a pair of jumpers....

This becomes a thread hijack.

 

But yes. assuming laminar flow.

 

Also assuming the buoys were positioned appropriately, but once reaching the buoys things would get interesting.

 

Often an example considered but never posted to illustrate ski path length when the rope shortens.

So for a given amplitude after shortening the rope skiing in the “X” mph stream; does the ski’s path over bottom lengthen or shorten?

 

Will the answer lead to running more buoys? (of course not).

@skibrain bouys would have to move at same speed as water.

In considering the stationary slalom pool - I figured what you would need is a system where in there were rails under water in 4 lines, one for left ball, one right ball, one for each gate. There would then be a "catch" on each rail and a cable with swedged fittings would "snag" the appropriate ball and drag it down the rail at appropriate speed/interval. Essentially when "reset" there would be 3 balls on each side rail at one end of the pool, and 4 gate balls (55's and gates).

 

Brings up more problems, you'd have to have a "pylon" with a retractable rope, so it could haul the skier off the start area into the pool and have him free of the back wall. SO this would probably come down from ceiling.

 

And then finally how do you "catch" the fallen skier. Essentially after falling the 30+ mph water is going to wisk the skier quickly towards some form of pump waiting to suck the guy up.

 

For that issue I picture some form of webbing/net that is turning so you get carried onto it up and out of water and dumped onto a padded platform.

 

Still haven't thought that part out, but obviously if your water is moving you have to get the skier up and out.

 

 

Which brings up the fact that it would just be easier to have a cable park type situation with still water and a motor eliminating the driver/boat.

Search YouTube for barefoot machine. I remember it took a LOT of horsepower and water but it is very impressive
