17,000 RPM turbine digital thermometer Tesla vortex style turbine

[jbhelix108]

I think you are selling yourself short that's a Rojas turbine.

[islandercafe54]

Dan, your efforts and outcomes inspire us, thank you. I have watched lots of your videos and you and your lady Rok. Have you studied Walter Russell stuff on harmonic periodic elements table?

[Lubobuba]

Very Cool

[KyleCarrington]

You can read about George Wiseman's theories on how a person might use a modified Tesla turbine to then use ammonia during it's state change (latent heat energy) to create a power generator based a heat pump, basically put. Interesting stuff!

[WiteBot]

what do you think the torque produced would be (approx.)?

[dzgfdg]

but, will it blend?

[YoLninYo]

interesting... I wonder if putting vertical score marks on it would give the rotating air a little more "bite" and allow it to transfer more energy to the spinning cyllinder/rod.

I don't know what practical applications this might have that would be efficient? Doesn't the Tesla turbine essentially do the same thing?

[AssilalOmega]

...some questions.... how the hell does this tube seperate cold and warm air??? ...to me it sounds amaizing stuff like this^^ ....

and what does rpm means??? round per meter???

[YoLninYo]

@AssilalOmega RPM means "revolutions per minute" 

[bwayne641]

@YoLninYo Oops, didn't see you had answered already, LOL

[bwayne641]

@AssilalOmega RPM = Revolutions per Minute

[inthepresentraw]

Thank you.

[mrbr549]

Not too interesting to me, I'd rather see you get back into solar projects.

[geminyo]

15,000 rpm and no torque. Neat trick though.

[kporter85db]

What is the purpose for this device?

[vidividivicious]

so... if you heat the warm air exit... you can make the air to move to the cold air exit... or not idk

[jackclark1981]

What was the temp? lol

[megasmart1337]

wtf is it for

[blinking801]

hmm interesting, how cold and hot does the exiting gas become? Also is there a difference in the velocity of the exiting gas at the two ends?

[JimboJitsu]

great video, interesting that you could pick it up off the table and it took awhile for it to fall out...

[social3ngin33rin]

LOLOLOLOLOLOLOL

I like watching it spin

It would be more efficient at spinning if the inside of the vortex tube were polished;

as well as the thermometer :) [but i think the thermometer already looks polished]

[muddymuddymuddmann]

WOW 15000 RPMs EVEN WITH THE RESISTANCE OF LAMINA FLOW IN THAT SMALL OF A DIAMETER TUBE. TO ME THAT IS THE AMAZING PART.

MUDDy

[veganath]

"T" is for thermom.........NO NO!! TURBINE...lol

[vertigo1090]

a sound warning would have been nice please warn me before i go def

[zetreque]

This is not a good video because compressed air is one of the most inefficient forms of energy. It is to be used only as a last resort in doing work.

[satan31337]

use to use these at work when we were sandplasting the air to our hoods woudl be ice cold so we ran a few of these on the line... they work OK but at -20 or more they pretty much dont do a thing, they work on air pressure, not air volueme so for them to function well u need alot of psi. atleast thats my experince with them

[ytams1]

Can the rotating air power turn a generator?

Instead of a compressor can the air pressure be generated by heating a long pipe full of air in the sun. The air would have to be cooled and recirculated?

[lvecsey]

do you have any projects that would be a relatively ideal fit for a really nice wood working project? i mean using a fancy material, like a specialty oak or rare Brazilian rosewood. I know a lot of your examples use quick wood working procedures just to get the mock up out there. but maybe a few of them would dove tail nicely with the wood working hobbies, to really craft something special, as a means of further inspiration.

[thesorehead]

I'm thinking that this is yet another way to use steam - instead of losing energy to the piston cylinder friction and valves in order to create rotation, you have the conversion from gas pressure to mechanical rotation with zero moving parts. Insert turbine, extract energy!

Maybe not efficient, but we needn't use coal to heat the water...

[GetMeThere1]

Very VERY interesting! Thanks for bringing this information to us!

[1BustedMyth]

Ah, ha !  so thats how they made the first jet engine ! ;)

[stfuuuuuuuuu]

that thing looks usefull to smoke weed...

[cwbh10]

Sounds like you have a mini jet on your hands :p

[CTOL1]

Rotating yes, 17,000 rpm?

It does prove out Tesla's blade less turbine though.

Pretty sure your reading a harmonic off that reflector?

If it was 17k I fear that would have come apart rather violently.

[denpobedi]

this is a water vacuum pump? Excuse me what is the main idea question?

[pieface1726]

i think you just made my ears bleed.

[steveBB30]

Aren't dentists drills simple air turbines?

[th3dig1tal0n3]

Does it works as cooling using pressurized liquids too?

[celluworld]

Future Videos never happen :(

[robot797]

you sell?

[GatheringSticks]

I think when they were testing those thermometers at the factory they had no idea the Dan Rojas would be spinning one at 17000 rpm.lol

[oisiaa]

Interesting, I have never heard of a vortex tube before.

[mondays89]

If it had enough torque it could power a car at idle. :-)

[CWojewodzic]

Another amazing video!

[Probewitch]

excellent.

[vention4wh]

This is interesting but not as practical as your black box heating system.

I'd love to see you bury a metal tube (maybe 30 feet long and a foot across) 4 or 5 feet down in your yard, then use a black box heater like the one you built a few videos back, along with a stove pipe that sticks out of the heater at the top. Connect them both to your home and watch as the sun heats the box, hot air goes up the stove pipe, then it sucks cool air into the house from the ground tube.

[vention4wh]

@vention4wh

In the winter you can use the heater to heat the house and in the summer the heater can turn into a device that provides the vacuum to pull the cool air into the house from the ground tube. Wonder how much that would cut your electric bill in the summer?

I just paid off my condo and now I'm saving up for a house. When the real estate prices stop falling, I'll take that savings and buy it. Then I can do cool projects like that. I love that sort of thing!

[19wael96]

imagine the centrifugal force

[norxcontacts]

I was more interested in seeing the temperature difference.

[GREENPOWERSCIENCE]

@norxcontacts Another video:-) on the way.

[threeredstars]

@GREENPOWERSCIENCE I love your vid's you should do one on atmospheric water generators. I think they are basicly ac units but  how can you make them more efficient?

[planto2005]

I have a thought exercise for a self sustaining tube. I have read that these can work by sucking the air out of the outlets.

My thought exercise was to imagine having two tall chimneys. One being the hot going up the other being the cold going down. Both would need to be well insulated and the vortex tube designed right for the flow rates and pressure differences involved.

this should produce a self sustaining separation of hot and cold driven by the energy already present in the atmosphere!

[GreySativa]

thats fun, did you get bored and figure this out or what? lol it gives me ideas.

[OttoBelden]

Cool! (no pun intended!) I like it! I never would have thought of using a vortex tube like that to spin a rotor. I'm looking forward to seeing what you will do with this! - Otto

[otakop67]

Very nice! I guess it works on the same principle as diesel engines and fire pistons do (i.e. air, when under compression, will heat in direct relation to the amount of compression). I learned this the hard way years ago when helping my dad in his shop. My arm brushed up against the copper tube that connected his air compressor's pump to it's holding tank and I got a very nice 2nd degree burn. Ah, life lessons learned in practical and painful ways are remembered forever.

[19wael96]

sounds very bad are you okay now ?

[otakop67]

@19wael96 Oh, yeah. That was 30 years ago and the only things I am left with now is a small scar and the education from it. Thank you for your concern!

[19wael96]

well thank you for sharing your experience

do you like fire pistons . compression ignition . diesel engines .

i like em alot

[dzgfdg]

4rth?

[88Kamikaze69]

So how come these things aren't used in houses say for using the hot air for general house warming and the cold air for something like a pantry? Might even find a use for this motor idea seeing as the air doesn't seem to have any problem escaping around it.

Although I suppose this isn't very efficient?

[breezebro]

@88Kamikaze69 They aren't used to heat or cool houses cause the air compressor used to create the air pressure uses more energy than the vortex tube produces. .In other words you could use the same amount of electricity used to run the air compressor to power a heater and get more heat for your money.

[AcidRaZor]

@breezebro I'd say that depends on the size of your compressed air depot. We have one at work we use and the actual motor for the compressor only switches on when the kpa drops below a certain point. Surely having 1 thing run some of the time is better than1 thing running all of the time?

Dan, this would be a perfect vid for you to discuss!

[breezebro]

@AcidRaZor Still, no matter, the total amount of energy used to create the air would be greater than the energy produced by the vortex. You would get more heat by putting the hot air compressor in the house to heat it.

[88Kamikaze69]

@breezebro

Yeah I figured it wasnt efficient but I was wondering if the more efficient models he were talking about wouldn't be if one factored in the benefits of getting hot and cool air out of one device along with the added safety bonus of not having to use a heater element seeing as I can't figure this thing catching on fire as long as the compressor was kept in a safe location, also the air would be a lot less dry with this thing then the air you get from a heater.

[breezebro]

@88Kamikaze69 Yeah, there are places where it could be used. In circumstances where it doesn't matter that the cost of generating the heat or cold is extremely high. NASA, or military applications for instance may have places where this type of solution would be preferred over conventional heating. Heating elements can be delicate but this seem pretty rugged. That's why a lot of new technology that we use is often developed first by government agencies where money is not a restriction.

[FenderGibsonWashburn]

I'm looking forward to seeing what you do with this new knowledge.

[HistoryTours]

nice

[SpeciaEdu]

do you know or recomendn any good T5 either HO or VHO thanks
