9" stainless steel Tesla Turbine in operation

[GeneBurbeck]

awesome!

You build a Tesla Turbine but didn't balance it?

[DanFrederiksen]

seems a little vibratory

[MrJetjoe]

I have to tell you all that if this was leaked out its not something useful. all the usefull things are lockedup tight. you have to think of it. batterys are fuel. if i say any more they wont print.

[xxsekoxx]

@MrJetjoe uhhhhhhh OK

[arpitdwivedi]

power output?? HP?? how much horse power is it equivalent to>>

[TheTeslaJet]

Hope to see a vid of actual work or voltage output.

Like the sheep vids you have very current to our countries and schools of today. MIT must be fun LOL! I pay for my flowjet's garnet everyweek, real life stuff. Drag,

[Patriotgal1]

Uhhhh... things like this need to be PERFECTLY BALANCED to work safely, and right. ONE of these days, I'm going to buy a vidcam, instead of another case of ammunition, and demonstrate how this is done, on a LARGE scale!

[capoferrari]

That was fast!

[kusrox]

i still dont understand how torque is measured. im doing a science fair on tesla turbines and its crucial to understand how to measure the torque. how does batteries and a radio transmitter hook up to the turbine to measure the torque? also if you have websites it would be most helpful thank you

[disndat11]

Read it again. He says the 'strain gauges' on the shaft read the torque. The transmitter and the battery just relay the info

toque is a measure of the turning force that's transmitted THROUGH a shaft (and power=torque*RPS)

When transmitting torque a shaft will behave much like a torsion bar, and twist. Sound's like the sensor used here measure the shear force fairly directly (you can use optical enconders and figure out the phase diference between then, saves having much mounted on the shaft)

Am a little puzzelled though. It doesn't seem like the turbine has a load, and so you wont get a true indication of torque

[brianwesley28]

How many RPM's did you achieve and how much torque did it develop?

[leopardgeckoxpert]

my friend built one and i could stop it with my finger so probley not that much torgue and probley around 13000 rpm

[steveBB30]

You are right that they are low torque. But most electric motors are low torque, and rely on gearing to change their high speed/low torque output into useable RPM/torque.

Remember that power (w) = torque (N.m) * RPS

so if you double the RPS, you can half the torque and still have the same power. Only disadvantage is that gearing to step down really high speeds absorbs a fair bit of power/needs very accurate machining

Put it on bicycle m8, Power the back wheel

[R3MUS2007]

what is that thing on the shaft?

[fablabamy]

9V battery and an RF transmitter - that's what is allowing a live feed of data from the strain gauges on the shaft (used to measure torque).

[R3MUS2007]

Do you have a website or something so that I can check out your research?

[urveen]

@fablabamy seems to cause some nasty vibration. Thought about slip rings and brushes instead?

[TommeyLeeReed]

A great way to increase pressure, and not the air pressure.
