Here is a Christmas tree with a twist! 

This metre-high tube uses a magnetically-driven Tesla Pump to create a beautiful water vortex. With green food colouring and lights behind it, it makes an awesome alternative to a Christmas tree!

Nikola Tesla patented the Tesla Pump (U.S. patent #1,061,142) in 1913. It featured only flat discs to supply pressure from the pump, and makes use of the same "adhesion of fluids to a surface" and boundary layer principles as the simple, but effective, Tesla Turbine.

This Tesla Tornado is made using a Subaru blower fan motor, complete with its 3-position speed switch mounted on the base. The blower motor has a flywheel fabricated out of Lexan with 6 neodymium magnets mounted in it.  It magnetically couples with 6 magnets in the Tesla Pump disc pack, which is inside the vortex tube.

The Tesla pump discs are magnetically driven by the blower motor flywheel magnets, so there is no direct connection. The pump disc pack is self-centering, and there is no rotating shaft, shaft bearings, or seals required!

Step 1: Materials and Tools

 Parts:

1.)  Subaru Heater Blower Motor, complete with stock plug-in 3-speed switch and resistor circuit. (from 1980's-90's Subaru or other equivalent electric motor)
2.)  Lexan Polycarbonate tube, approximately 1 metre or more in length. 6 inch is a good diameter.
3.)  7.5 cm length of same 6" tube as above for motor mount. (or custom length to your motor specs)
4.)   2 of 8 inch x 8 inch Lexan plate, 1/4 inch thick. (one for Motor mount plate and one Tube bottom plate)
5.)  3 of brass threaded rod, 1/4 inch x 8cm, for motor mounting, with wingnuts and washers.
6.)  12-volt heavy-duty on-off switch. 
7.)  6 of 1/2 x 1/2 inch neodymium magnets, preferably N52 strength
8.)  6 of 3/8 inch x 1/32 inch neodymium magnets for each layer of discs (typical 8 discs x 6 each = 48 magnets)
9.)   Fondue base, found at a Thrift store
10.)  Polycarbonate solvent  (methylene chloride)
11.)  12-volt car battery or equivalent
12.)  CD discs, from 3 to 30 depending on design. (less discs require more rpms to get same effect. I found 8 discs worked well)
13.)  Crazy Glue 
14.)  4 of 1/4 inch bolts, nuts. Brass or stainless preferred, for bolting Motor Plate to Tube Plate.

Tools:

Circle-cutter attachment for a drill press. (Can substitute a jigsaw if necessary)
1/4 inch tap for threaded holes.
Sandpaper 
Drill and 1/4 inch bits

Would it be possible to add a waterproof  version of this:http://www.instructables.com/id/LED-Throwies/ to the water chamber? It would save having to plug in/arrange lights behind it and make it possible to move around or farther away from an outlet.
Shades of Grey in reply to Shades of GreyNov 19, 2010. 2:15 PM
minus the magnets of course, maybe add some sort of bobber type float to avoid getting sucked into the bottom, with just enough buyoancy (sp?) to stay away from just floating on top also.
mrfixitrick (author) in reply to Shades of GreyNov 19, 2010. 4:58 PM
That idea could certainly work. I did try a regular light bulb and was able to get it to completely submerge, and control it's height in the tube!
Szajba says: Oct 6, 2010. 4:02 PM
epic idea
riverreaper says: Oct 2, 2010. 3:10 AM
if you put a chamber in it like half way up with a hole in the center for the votex to get threw it would the water all just end up pushing its sellf out the top or would it not even rech the top , i was tinking of away to get fish to survive init , ok dizzy fish , probly have to stop it to feed them , wonder if they would still swim in cyrcals ?
mrfixitrick (author) in reply to riverreaperOct 2, 2010. 11:06 AM
Hahaha, I had the same thoughts myself! The Tesla Tornado would make a great fish exerciser...to build strong and healthy fish. The slow ones, however, would be subject to natural selection...;)

Since it has a 3 speed control, you could start them off easy, with a gradually increasing exercise program.

put floresants in your water dich the crismaslights an put a blacklight tube style as bulbs arnt that good , then you could try also as most artstores sell floresant paints you could drop difernt colors in as its spinning , result the best lava lamp anyone ever seen ...just an idea to your already asum job
mrfixitrick (author) in reply to riverreaperOct 2, 2010. 10:49 AM
Fluorescent is a good suggestion...I'll try that at Christmas this year!

or tittle wiches
mrfixitrick (author) in reply to ninja doom25Jan 15, 2010. 10:41 AM
 Both are good suggestions. I tried little duckies that were fridge magnets, but they got stuck on the discs magnets and messed things up. I tried beads, but they just swirl around at the bottom. 

A light bulb or soda bottle can get sucked to the bottom easily...movie about it to come soon!  Subscribe to my YouTube at  www.youtube.com/mrfixitrick

i love it this is crazy but my sister thinks you should put miniture light farm animales in it
Doctor What says: Jan 13, 2010. 1:01 PM
 This is great!  It would be fun to see what would happen if you sent a duckie down it...
mrfixitrick (author) in reply to Doctor WhatJan 13, 2010. 2:14 PM
 Hehe, I did! But the ducks were fridge magnets, and got caught in the magnets of the Tesla discs, jammed them up, which required me to dismantle the whole thing!!

Why are you running iMovie 09 on your iMac?
mrfixitrick (author) in reply to robots199Jan 1, 2010. 5:21 PM
 What do you think I should use as a movie app?
BlueFusion in reply to mrfixitrickJan 4, 2010. 3:30 AM
iMovie is fantastic if you're not a pro. If you happen to know your way around a video production studio, Final Cut Pro is the choice of many production houses and TV stations. And me. :) 
MajesticNarwhal in reply to BlueFusionJan 5, 2010. 4:44 PM
 Wow that's a little insulting. I make awesome movie shorts using only iMovie HD from either 06 or 08. If your a real pro you can make great movies without the use of fancy, EXPENSIVE, and over-achieving applications such as FCP. 
BlueFusion in reply to MajesticNarwhalJan 12, 2010. 2:45 AM
I had no intention of insulting you. Sure you can make great stuff with iMovie, that's what I said. Yes it's fancy and expensive, but it is still the choice of the majority of professional video producers and TV stations. And while you can make great stuff with iMovie, with a bit more time and skill you can make really really great stuff with FCP :)

 Brilliant use of technology and design. You always show the reader a way to have fun with science.

Thanks, mr robot... Video is now up, and more to come!

My cousin has a hexagonal tank that's roughly 5 feet high and 3 feet across.  I wonder how 5 of those would look going in it....  (drools)

Happy New Year!!!

Beautiful!
That's one of the longest vortexes I've seen!
For length of funnel vs diameter, it IS the longest I've seen.
