Recirculating Tesla CD Turbine with Air Turbo-Boost
This instructable will show how to make an off-the-grid, Tesla turbine-powered blender made from many recycled parts.
It runs on a self-powered, re-circulating system from the forces of Earth(magnets), Wind(compressed air), Fire(solar) and Water(pressure)!
In tough times or times of disaster, we might need to make McGyver-like contraptions, with the things we have on hand, in order to survive...or to have fun!
Ok, let's say the electric grid power is out...you couldn't pay the bills, or there's some other disaster...but you wanna party anyways.
You need a blender for the party...
You could use a 12 volt battery, with a 120 volt inverter, and simply plug a regular blender into it as an easy solution.
But, hey, why not make a recycled Tesla CD Turbine Blender,
on a self-powered, re-circulating set-up?
With a cool foot-operated, air-powered, Power Boost function for tough blending chores!
From wikipedia , "A Tesla turbine consists of a set of smooth disks, with nozzles applying a moving gas to the edge of the disk".
The Tesla CD Turbine I make is made with recycled CD's, CD spindle case, supermagnets, a nozzle and glue. I have 3 previous instructables that deal with it's basic construction.
This powerful, magnetically-coupled Tesla CD Turbine Blender is different because it works "off the grid", and because it uses recirculated water pressure and air pressure...at the same time!
The way it works is that a solar panel charges a 12 volt battery, which powers a 12-volt air pump and a 12-volt bilge pump. The water pump sits in the recirculating bucket and makes water pressure for the turbine to run.
Compressed air is stored in a tank, which has an air line going the foot-operated valve. An air blast gives additional power and torque to the turbine when required, by way of the foot valve.
Can a Tesla CD Turbine, made of recycled CD's and glue, develop enough power from solar-powered air and water pressure, to perform as a portable blender??
The answer is a resounding "Yes!" (See movies following!)
Any turbine on air pressure can be dangerous. I have added a polycarbonate protective cover over the turbine for personal protection. Something similar is mandatory when using compressed air with the CD Turbine, because of the possibility of CD discs or case exploding at high rpm! (see my warnings in other instructables and movie below of explosion! )
Have fun and blend safely!
I always order from the best selection of neodymium super-magnets from K&J Magnetics here.
The following shows some preliminary testing of the concept of combining air and water pressures in the CD turbine at the same time.

The following shows the possible result when excessive back-pressure, and an over-exuberent throttle foot, combine with such a funky, recycled, CD cakebox system! (Lesson learned: Don't turn on the air pressure too fast!!)
