The Canadian ACES have finally put up a web page. It includes our application video in realplayer format. It's my first page with video on it but it seems to work.

Let me know if it works for you or not.

Comments welcome!

Everything works great. Good Luck to your team! John

The Rust Renegades welcomes the Canadian "Aces" to the web ring and to what I call the RAT(Really-Anxious-Teams) PACK!

Each picture takes about 43 seconds to load. With 6 pictures that's quite a really really large web page. Would you like me to resize them for you so the actual picture size is the same as the display size?

-- Trevor (webmaster@deepscience.com), March 12, 2001.

For me it pops up like anything else. I don't notice the size of any of these web sites. A 1 gig computer with a cable hookup is the only way to go.

Yeah, 1.08GHz is sweet for me too, but why have pictures 8 times bigger than their display size? (How fast can celeron 600's go anyway? Ans: depends on how hard you throw them :)

Hey I've got a question. What on earth is that thing they demo at the end of the video? I don't get it. You'd have to have a ginormiously large boat in the top and a light dingy in the bottom for it to work because of the weight of the water you have to displace. And you wouldn't always have a heavy boat around anyway which weighed equal to an entire lock full of water. So you'd end up just letting the water in the top or out the bottom like normal surely? It would be a way of partially reusing the water if you really wanted to decrease the amount you let through but surely it would only be a partial solution which got the boats and water to equilibrium?

Please note, I am not Canadian so I'm not so informed on locks ;) Just curious.

-- Trevor (webmaster@deepscience.com), March 12, 2001.

The weigth difference of the boats is no consequence. When the boats enter the chamber, they displace their exact weight in water. If a canoe enters the top chamber, it displaces it's small weight in water. If a large yacht enters the bottom chamber it displaces it's large weight in water. The result is that the entire chamber weight remains equal. Then they add 1 foot of water to the top chamber, open a valve in the underground plumbing, and down goes the canoe, up goes the yacht. Worked in 1906, works today.

Catchya,

Ok, here's my questions for today :)

Why does the yacht go up to the top and not just the quilibrium position of both chambers?

How do they add a foot of water to the top chamber if the top chamber is already at the height of the high side water level?

yours confusidly,

-- Trevor (webmaster@deepscience.com), March 12, 2001.

O.K., we kinda glossed over a detail here.

The upper canal is 1 foot deeper than the lower canal. The extra foot of water is taken on before the doors open and the boats enter, not after as our video implied for simplicity. The motion is controlled by a valve between the hydraulic rams. The extra foot is carried to the bottom during the cycle and dumped before the doors are opened in the lower level to let the boats out.

Is this helping?

The following URL has some info. that might be interesting or helpful on the liftlock.

Ooooohhhhhhh. I'm starting to get it. I didn't realise that it basically used complete containers of water that it physically shifted up and down. My goodness what a strange way of doing it! Wheren I was confused was that I thought the blue water in the demo indicated the water the boats were sitting in. I guess the blue water meant completely separate hydrolic fluid. I do get it! yay :)

The system would only work for relatively small craft but it might be quicker than using the other drain method. It would move less water downstream for sure.

Interesting.

-- Trevor (webmaster@deepscience.com), March 12, 2001.

That's right, the water in the chambers is seperate from the water in the hydrualic system. It is just river water in the big tubes though, not hydraulic fluid.
