SinkScience #10 - Shake Flashlight Shaker

[lookkool3]

wont the capacitor blow up from over charging?

[MrfixitRick]

@lookkool3

Yes, anything could happen. This is an experimental apparatus and should not be left running unattended.

[bkfilipi]

I was wondering if you know this? if the magnet was an electro magnet connected to a battery then moved in and out like your doing here ...would there be more electricity generated?

[MrfixitRick]

@bkfilipi

There could be more additional electricity generated if the magnet was an electromagnet...but it would require additional force to make it run.

Unfortunately, this device was at the limit of power that the faucet water pressure could produce, so an increased magnetic field with an electromagnet would stall the motion of the device.

[LUCKY4908]

your wasting water

[MrfixitRick]

@LUCKY4908

I get water pumped from a well. It's rained for about 8 months, so there is no lack of water here.

[djdsfhakdfhlksdhklf]

HAHA pretty fun, GREAT GREAT!

check this users:

gfcgamer lidmotor

jeannacav

gfcgamer videos is easy to replicate as long have hard materials, and good water weight over the tubes going down.

Jennas explain quite well in his videos that use few voltage to make hundreds.

[HeBreaksLate]

I would love to know how grossly inefficient this system is: how little energy that shake light is putting out for how much energy that water pump is using?

[MrfixitRick]

@HeBreaksLate

If the water pump is running anyway, say to fill a sink, then this system is 100% efficient. If the pumped water is not used, then this system is about 1% efficient.

BTW, efficiency was not one of my criteria in this experiment.

[HeBreaksLate]

@MrfixitRick I figured efficiency wasn't a prime concern. It never was for Tesla. A lot of amazing proof of concept stuff, but very little that we practically use today.

[MrfixitRick]

@HeBreaksLate

Tesla invented the radio...is that not practical?

Most AC electric motors today are of Tesla design, such as found in the amazing new Tesla car.

AC electric wires on poles over long distances have also proven to be fairly practical; Tesla pushed hard to make that happen.

And I understand that the original Tesla Turbine at Niagara falls is still working...

[Dishfarm]

It's always fun to play with stuff like that. Sometime at work I'll spin a fluted tap or drill inside a tube using compressed air.

[hitachi088]

Wasting of Water .

[shepherdsmusic]

use steam instead of water pressure and collect the steam after it goes through the turbine and do reverse osmoses to produce distilled water to drink.

[hellokitty4088]

a.......he is a nerd with the d 2.5 2. and what deos that mean.and im geting off this website

[CoolFire666]

Funny machine, but exactly what is the practical use?

[smithad7]

lol Just buy a flash light that plugs into the wall, that flash light is suppose to avoid using power from a utility company, ether way I like it and I get where your coming from. You solved the true problem with it, that you have to shake the damn thing for it to work. Dude Im just a lazy. However you could have just used your time and energy to shake the damn thing rather than inventing whatever that contraption is you got going there

[FCKEVRY1]

Those shaker flashlights are SO useless!

[BrokenHorn90]

So is that comment.

[FCKEVRY1]

And yours was useful?

[silntdoogood]

LOL I was thinking, that it's kinda cool, but kind of defeats it's self because your expending power to power it. But then the second one added! Still kinda useless, but a very cool theory.

[dormantreign]

Love it bud, great use of free power...id have gave you 6 stars but it only went up to 5 :P Now if the power goes out ill be getting free power from my tap and the phone lines :P

[skullzcrusher]

Thats nice.. whats fun when you think about it is that you can use the same mechanism but to power another product... :P that can be usefull if the power goes out, you can charge your flaslight, then maybe power something else? ike a radio? or would it need more power?

[MrfixitRick]

@skullzcrusher

It can make a watt or so of power from faucet water pressure, so it could power a small radio. The usefulness in power outages works as long as the water pressure continues.

[eafws17]

Where is all that water going...down the drain?

[MrfixitRick]

The water can go where it is needed...to fill a sink, water a garden or any other low-pressure supply. I have a well that costs 5 cents an hour to run to provide the water, and live in a rain forest with no lack of the wet stuff!

[thymark]

So have add wery short video respond, about turbine what will in short time build

[MrfixitRick]

Cool! Thanks for the video. I wish you success in your turbine building, and let me know how it goes.

[thymark]

Can you allow me video respond, that can ewerybody see what we are talking about.

[MrfixitRick]

Thanks for the reminder; it's been approved.

[NOLIMIT69NOLIMIT2000]

Thanks for the reply. I do apologize to a point. And yes I was having a bad day/night. And I watched that one already. And that ain't my truck and thank you for letting me know that is was still on my page so I could delete it. As for your stuff in general it ain't that impressive but neither is mine. But don't waste stuff when your doing it. Use a pump. And I'm some what sorry about all the language.

[NOLIMIT69NOLIMIT2000]

Wait I got more. Why don't you put some type of fins such as old Cd's cut into slices in between the Cd's in the turbine so that you can get better rotation from the same amount of pressure. Maybe even drill holes in the center for the water to run out of where the fins meet the center, I think you would gain a bit more force there to. Also might relieve some of that pressure that is bloating out the spindle case. But I wouldn't listen to me.

[MrfixitRick]

Thanks for the suggestions.

The Tesla design uses only flat discs with spacers, and relies on the boundary layer adhesion (drag) on the discs, in a smooth gradual manner by the fluid, rather than by diverting the flow abruptly. Fins change the nature of the turbine into a normal cupped or bladed design.

The Tesla design must maintain pressure in the case to work properly. The fluid exits out the centre after doing its work on the discs.

[MrfixitRick]

I appreciate that some folks have concerns about the faucet water used. I live in a rain forest where a lack of water is not so much of a concern.

My latest movies show a recirculating system with 12 volt bilge pump run by battery and solar panel, and compressed air through a 12 volt compressor, battery and solar.

[NOLIMIT69NOLIMIT2000]

Quit wasting water on dumb shit like this. Asshole. Work with a pump or something and reuse it. Fuck make a pump out of that thing that can power it's self. Fucking bullshit.

[adamalden]

the thing that gets me is that your using magnets to hold shit together... they have no real use in your "tesla turbine" except to hold shit together... your thing works but there are better ways to do what your doing... lol

[MrfixitRick]

The magnets do more than just hold shit together. Yes, they do help hold the disc pack together, but the crazy glue works better.

The magnets act as a drive system for many attachments.

The magnets make possible to eliminate the shaft and bearings and seals of the turbine, which is a very big idea.

A shaft-less, bearing-less, seal-less turbine could have many applications.

The magnets can also give power directly by using coils of wire to pick up the energy.

[adamalden]

Well all I see is is water spinning a thing held together by magnets... And those magnets hold another thing to the top of the case. it's a cool thing but it wouldn't work as a saw as that would require torque something this device does not have. if you would concentrate on taking this idea and turning it into something that produces energy I would be impressed. I hope that I haven't dampened your spirits.

[MrfixitRick]

The first thing I did with the first turbine I built was mount a skilsaw blade on it magnetically and run it at very high rpm.

I admit it did have low torque and would only carve a pumpkin or cut 1 x 2 pine. But hey, its a CD case and CD's !!

If I had money I'd build a powerful Tesla Turbine for a vehicle.

But I don't, so I do funky home experiments of ideas that might inspire others.

[Ixtheemperor420]

Can you estimate the cost of building a Tesla Turbine powerful enough to run a small vehicle like a golf cart or a scooter?

[MrfixitRick]

That is hard to estimate. It would depend on many factors. It would likely cost between $2000 to $20,000 to build a 10-20 horsepower Tesla Turbine. With mass production these costs might only be 1/10 of that estimate.

[Ixtheemperor420]

I can understand that, and the mass production would be a massive initial investment until the production line and sales got going. It's a bit out of my ballpark as far as disposable cash goes, heh, but I'll keep an eye out for other investors.

[thymark]

Hi, MrfixitRick if you have any technical drawings, can make you calculation of real cost for one and ten turbines. Or enibody who is interest.

[MrfixitRick]

What kind of turbine are you interested in? A CD Turbine like this one, made from a CD case and CD's and magnets? Or do you mean a true Tesla Turbine that will run on steam? How big do you want?

I don't currently have technical drawings. They are available at places like Phoenix Navigation and in Tesla Turbine books.

The cost for a 23 disc CD Turbine like in my movie is about $80. The cost for a small Tesla Turbine with metal discs would be from about $200 to $2000, depending on materials.

[thymark]

I mean real one, i work like designer in compani who manufacture fans, we have all kind of machines. And 2000 USD is weri weri hight, I will tomorow create at work one tesla turbine from metal and will show it here, will put there drawings and price.

[MrfixitRick]

Looking forward to it!

[RomanStinespring]

so its like a train wheele exept reversed

[MrfixitRick]

Yes, very similar to a steam engine setup on a train.

[starsgaze3]

The mechanical medium makes it very noisy and

not very efficient because it can't get any speed.

If i can suggest, try putting two magnets on your cd on the opposite of each other, and then take the coil out of the flashligt, insert a solid iron core in it and place it about 1/8 inch above the cd magnets(verticaly) and you made yourself a magneto. your cds will spin much faster since it is now balance and you eliminate the noisy mechanical setup. give it a try.

[MrfixitRick]

You misunderstand... the point was not to make it quiet and efficient. It's to make a cool mechanical way to charge 2 flashlights at once. For the fun of it.

I am building a dedicated turbine-generator similar to what you speak of, but that is a whole different project, as the N-S magnets cannot then be used as drive magnets like I have done here.

[dagger86]

Make a circuit with some capacitors to smooth the current.

[iggy151]

How does the load of a second flashlight affect its performance?

[MrfixitRick]

Good question! The second flashlight slows down the CD turbine a couple of hundred rpm.

A third flashlight can be added if the water pressure is having a good day ;)

[iggy151]

I figured so, with the weight of the magnets inside the flashlight. If you're open to new ideas, maybe solder a USB slot to the battery inside the flashlight and charge an iPod? If the voltage is sufficient of course. I think a turbine iPod charger would be pretty fresh.

[30GB]

i wonder how much is your water bill every month

[MrfixitRick]

My water is on a well...costs me 5 cents an hour for a whole lot of fun!

[MrfixitRick]

I like your green generator. The bottles are a cool idea. I wondered about what was used to attach the tubes to them?

[isaisai9192]

u can u sit as awater tourbin amplfi and power som huge note u a recargable bat

[MrfixitRick]

With enough pressure and volume, the Tesla Turbine design can power anything. Tesla had designs for cars and ships up to 10,000 horsepower. His smallest commercial turbine could be held in one hand and developed 110 horsepower. They were mostly run on steam, but are capable of running on any fuel.

[shepboy8]

how do you make a cd turbine????

[RuFiOooooo]

minus the magnetic coupler of course.

[RuFiOooooo]

so basically youve just made a pint sized hoover dam...neat?

[benutzer2]

it would be interesting to use two turbines, and reorient the output of the first to the input of the second. As well as reorienting the light output to be forward. Would be an interesting experiment.

[leonidas28]

I wonder how a Tesla Turbine compares to a regular turbine in terms of efficiency. Unless there isn't much of a difference between the two to begin with.

[MrfixitRick]

It depends on the particular circumstances, and who is doing the measuring of what. For example, a regular turbine won't run on straight biomass combustion gasses without clogging up. It needs expensive filters and polishers to prepare the gasses for burning. A Tesla Turbine has recently been proven to work well in that situation, making it more efficient in that sense.

See the wikipedia entry for "tesla Turbine" for more info on efficiency.

[Faintedimpact973]

invent a dildo for girls that can do that

[MrfixitRick]

This movie is now available as Closed Caption.

[JesseMacEachern]

your a smart guy...really smart...

[ppardee]

You are mad! MAD I SAY!

I am so jealous!

[MrfixitRick]

Don't be jealous...you, too, can be insane!

Insanity beats jealousy every time.

[jcobaltss2005]

so in that flashlight is theres gotta be a capacitor. does a rechargable battery do the same thing?

[MrfixitRick]

That's right, it would work, but perhaps need different circuitry.

[elvss2]

awesom videos

[treiopt]

Respect for those who are capable of "DIY". I Know people who don't know how to change a light bulb. Regards!

[hsdoofc]

do you think there is a way to do this backward, say the magnet and flashlight moves back and fourth causing the CD rotate, my fear is that it won't make a 360 turn and instead just turn the CD to the middle then pull it back

[MrfixitRick]

One could set up things like you say, and the only way it will work is because of the flywheel effect to bring the linkage past that "dead spot". The momentum of the discs and magnets inside the turbine would keep the linkage moving.

Same effect as a car engine, which wouldn't work without momentum to bring the crankshaft around.

[treiopt]

jeez, you use 100 Watts to light a 0.1 Watt LED. Nice work!

[MrfixitRick]

Very astute! Most folks just waste that power every time they turn the faucet on...what did you do with it today??

[vietmata]

looks like a fuck machine

[MrfixitRick]

beauty is in the eye of the beholder...

[toyakeitoyakei]

なるほどね

[MrfixitRick]

私は将来を参照してください !!

[RHEAD100]

You are one cool Dud ! ! !

Love your videos

5 stars

[Luky1Jay]

Hey man, i got one of these things for christmas today, they are cool! The batteries are epic. I've had it turned on for about 9 hours almost, and its still going. Its pretty similar to yours, 1 led also.

What i was thinking is, maybe we could use that battery power to power more LEDS? This would make it much brighter. We could easily fit another 4 (total of 5) LEDs at the end of the torche, so its much brighter, and them batteries dont goto waste.

Though im not good with this stuff :(

[MrfixitRick]

The shake lights are designed with very thin wire, just enough to run 1 LED. Running too many LED's could overamp the wiring. The voltage may need to be increased as well.

But it might work for one or two extra LED's..try it!

[Luky1Jay]

Um, maybe we have different torches then? Mine works with the same kinetic generator with the magnet, just like yours, it charges 2 watch batteries. The watch batteries power the LED.

[H0D0NKAIN]

I'm not a science buff but out of curiosity, how is that 2nd flashlight being powered up?

Is it from the 1st flashlight's electro-magnetic field?

[MrfixitRick]

Good guess, and I certainly tried it that way, but that didn't work.

What happens is that the neo magnet in the second flashlight gets pushed and pulled by the direct magnetic coupling action of the magnet in the first flashlight. No electro, just magnetic!

The electromagnetic coil in the second light charges it's battery from it's own magnet movement.

[Zoobilord]

why did you put the piston arm so close to the middle?

[MrfixitRick]

Good question!

The arm is close for best torque, to push and pull the shake-light magnet through the magnetic resistance of it's coil of wire. Also, any longer of a radius will make the rod hit on the shake-light case.

Also, the turbine has limited torque, so it was a fine balance to get the radius to the con rod arm just right, especially to enable adding the second light.

[windoes98se]

this is amazing

[thegreymen51]

If this thing uses the energy from the water spining what are the magnets for? Just to add atactment?

[MrfixitRick]

The magnets have several functions, attachments are one of them. There are 1/32 inch spacer magnets between the CD discs in the turbine to space them at the correct distance apart.

There also are 6 larger 1/2 inch magnets on the top disc inside the turbine. This enables a magnetic coupling to the magnetic coupler (also with 6 magnets) that you see on top of the turbine.

The magnets also create a rotating magnetic field that can generate electrical power with coils.

And more...much more!

[Kleap]

Your impellar is far too wide .I bet that spins at 300 rpm. at 10 gallons per minute.

You can bump the rpm up to 1,900 at 2,5 gallons easy if you re design it.

[MrfixitRick]

Thanks for comments.

The impeller is quite wide, and was an experiment to look at the vortex effects and the flywheel effects of a larger mass of fluid.

It spins up to 1200 rpm, at about 2-2.5 gallons per minute. What you see here is indeed about 300 rpm, but with a load.

I have found it difficult to reach above 1200 rpm on 50 psi water pressure. Do you have a CD turbine working design that does so?

[sherifahmad14]

lol put a dildo on the end and sell as sex machine make lots o money

[MrfixitRick]

Tell you what...you make and sell them and I only ask for 5 percent of the gross for my share. Deal?

[agungk]

too complicated.

instead using shake flashlights that way, you could extract the coils, and put them directly over your tesla turbines (with magnets on them).

arrange three of them in 120 degrees and you have a balance system. no problem with vibration.

[MrfixitRick]

Hehe, I tried that and it didn't work too well. The all north-up magnets in the turbine don't produce enough power from the coil to light the LED. It might work better with alternating n-s-n-s magnets, or with multiple coils in series.

I kinda like the vibration and con-rod linkages...like an old Briggs & Stratton or steam engine!

[bongman4ghz]

can you plx explane what this is & what it does,

its interesting & neet.

[MrfixitRick]

Read the "more info" >>> for some more info.

To sum up, the Tesla CD Turbine is a disc-type turbine based on the invention of Nikola Tesla 100 years ago. My turbine uses CD discs spaced by magnets inside of a CD case with a nozzle glued on, and this one runs on faucet water pressure.

The turbine, having magnets, drives a magnetic coupler which has a connecting rod attached to the magnet inside a shake-flashlight. A second light charges by its magnet moving magnetically with the first one.

[BASEBALLAPPLEPIE]

GREAT VIDEO. I now have 2 favorite sites.

[airbuscrazy]

make for a good strobe light

[jlleventon]

I like sympathetic relationships!!!

How many Gallons pr Minute(GPM) for spin?

I wanna make it into a tea kettle (will it work on steam?)Hard drive platters are non ferrous!!

rockaholic

[MrfixitRick]

Ok...1-2 GPM gets it spinning, 30-40 psi water pressure at the nozzle. This CD Turbine unit does NOT work with steam; warps the polycarbonate CD discs within 2-3 seconds. Will work with compressed air...but gets dangerous at 15,000 rpm.

A true Tesla Turbine loves steam. Nikola Tesla built his first 8" to operate at 35,000 rpm and about 40 horsepower, later models into the thousands of horsepower!

There are hard-drive platter Tesla turbines on the web.

[TWISTYTWAT]

you spin me right round baby right round :)

[rocketcane]

ok, i got everythign working on my bike powered flash light, but when ever i stop pedaling it stays on? witch it is suposed to do, but whut kinds of mods did u do to urs becouse when urs stopes the light turnes off? pleeas explain or send me a short vidio of showing whut u did and send me the link idk but thank u.

[MrfixitRick]

I selected that shake flashlight out of several because it didn't work right, and thought it would be good to show the charging action. If you want that effect with yours, you need to bypass the little battery they have wired into the circuit-board for the light. Or find a shake-light at the dollar store that only flashes without charging.

Most shake flashlights have a supermagnet in the on/off button in the outer case. So pass a magnet over the light circuit-board to turn your light off.

[rocketcane]

im doign this exact thing almost. with my bike, i made it so the magnet pumps up and dwon when u pedal the weels btu i lost the flash light part of it so all i have is the magnet

[MrfixitRick]

Hey that's a cool idea!

Too bad it broke, but now you have a great neodymium magnet to do homopolar motor experiments...see my videos called "Homopolar Motor With 5-speed Shifter " and "These Hearts Are On Fire"

[unclewooly]

Hi Rick, Good job on duplicating the tesla turbine principle with water as the source. We have seen the speeds capable with your air powered turbine being far more efficient than water for obvious reasons. Have you concidered using a Venturi principle on the inlet. It is of my opinion that with the introduction of air Venturied through the inlet using the water pressure, it would increase the flow rate through the turbine maybe 3 fold ? (Giovanni Battista Venturi) if you want to look it up.

[MrfixitRick]

I did consider a compressed air inlet to give a pulsed boost to the water flow. I'm familiar with the venturi principle from automotive carburettors, but I don't know if the introduction of atmospheric air into the inlet would work.

What you suggest would be an interesting experiment, and I do need to work with different size and shape nozzles now to see what is best.

[unclewooly]

Hey Rick You only need to reduce the diameter of the inlet a small amount to create the venturi principle. You then return the pipe to its original size (like an hour glass exaggerated).The air inlet is introduced at the narrow point of the hour glass. Some gas fittings use this principle to mix air with gas. You could get a faucet to bolt straight on to your existing gate valve. In essance the principle would work like a jaccuzzi jet. Jaccuzzi jets are nothing without the vacumed air mixed in.

[cityUFOinvestigators]

I really enjoy your videos.good job,

[Bobensen]

Hey Rick.. when will 9 be up??

Good job though!!

[MrfixitRick]

It's coming real soon,"SinkScience#09 - Tesla CD Turbine Power Generator." using a Subaru rad fan motor as a generator. A couple more videos in the works , too!

[vartio]

hey man good work

i was thinking about Tesla and maybe use Patent number: 390721 or Patent number: 381970

somehow?

[markuks]

know what you should do... make one big copper coil and see if you can power your computer. good idea though put counter weights so your turbine won't shake to destruction.

A question how much is you water bill? by the looks of it, looks high

[MrfixitRick]

The turbine won't be able to put out enough power to run a computer without hooking up to more pressure...i.e. the mountain creek next to me. I will try wrapping the entire case with wire at some point.

My water bill is nil, just a few cents for power for the well pump. I could see that this would be a problem for some on water bill, in which case recycling would be preferred. Run the turbine outlet to fill the sink, a barrel or the pool, or use for low-pressure garden watering.

[markuks]

I considered that i have all the materials all i need is magnets. will it work with ordinary magnets or does it have to neodymium

[MrfixitRick]

You need neodymium magnets or the clutch will slip, that is, the magnetic coupler won't work. I used 1/2 x 1/2 inch N42 neodymium cylinder magnets, but you could get by with smaller ones, especially if they were more powerful. Check out my building instructions at Instructables(dot)com, see link in About This Video

[Kleap]

I build plastc water diven gizmos. I was able to reach 8,300 rpm on a rotating impeller. The impeller needs to be very thin. An 1/8 inch thick jet stream of water on a 1/8 inch thick impeller should boost your rpms as long as the exit water in your housing can exit quick as to not drag on the back side of your impeller. We dont want stuffing box pressure.

Sharpen the back side impeller blades to an edge.

[MrfixitRick]

Do you use a central opening and the Tesla design? Or are you talking about an impeller which is an entirely different design?

[Kleap]

The water jet should contact the impeller and immediately exit the housing though a large bottom or side port. A central exit port would have the water flow fighting against the centrifugal force of the spinning impeller.

[MrfixitRick]

Hehe, What you are talking about is an entirely different type of turbine.

From WiKipedia:

"The Tesla turbine is a bladeless centrifugal flow turbine expander patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. "

The Tesla Turbine uses a different principle involving viscosity and adhesion, and smooth discs, instead of cups or blades, to transfer the power.

[MrfixitRick]

Sorry, I meant, do you use a central exhaust outlet like the Tesla design?

[Kleap]

You could pick up rpms by moving that flashlight oscillating rod to connect closer to the central access of your spinner

[MrfixitRick]

ahah...really got you thinking, eh? thanks for the refreshing attention to detail!

I optimized the radius of the rod on the magnetic coupler such that the magnet was moved through the coil far enough to light the LED. If the rod is any closer to the center it won't have enough back-and-forth motion to flash the light.

Believe me, I spent a few hours with this rig to get it to do this!

[Kleap]

I designed and built over 200 different configurations of light weight water driven motors. You told me you cant get past 1,200 rpm at 50 psi. I dont know what Tesla knew about the stuffing box pressure or cavitation effects.With your configuration you will always have a large energy loss at the impeller when completely immersed , blades or no blades.

[MrfixitRick]

Tesla's design works on the principle of adhesion. The fluid goes into a nozzle, where it is accelerated. (Same as your designs, I presume.) As the high-speed fluid leaves the nozzle and enters the case, it is forced between a series of smooth, closely spaced discs. The fluid spirals into the center outlet, while releasing it's energy to the discs.

A Tesla Turbine or pump will not cavitate, and the design can handle shock waves and implosion better than any other turbine or pump type.

[Kleap]

I saw your videos. Does Teslas engene do better than 1,200 rpm? Why dont you use two closely spaced discs in a thinner "case"? We know you cant change the water pressure but you can streamline the parts. I see your using 4.5 inch wide CDs. If you cut your own 3 inch wide discs , reducing the diameter should raise your RPM. Like I said before I can make 8,300 rpm. from the indoor water supply.

[NOCNOTCAUGHT]

Pretty slick!

[cheriebibo]

I really enjoy your videos. I love the faucet water driven turbine. I think it is very cool that you are able to get the second flashlight to shake just by its proximity to the first flashlight. *****

[MrfixitRick]

I think Tesla would have enjoyed an AC flashlight recharging wirelessly on a Tesla Turbine.

[AdminOnDuty]

Innovative :)

Keep up the good work!

[BurntRevenge]

now that i think about it, how big is your water bill because of the CD turbine?

[MrfixitRick]

It costs less than 6 cents an hour for the well pump to run the turbine = too much fun for very little!

[BurntRevenge]

lol, that is cheap, if only my water didnt cost that much.... ahh.. the possibilities....

[MrfixitRick]

You could run a recirculating setup with an inline electric pump. Then you could play for pennies. Or use the CD Turbine outlet water for some useful low-pressure application like a garden, a pool, or to simply fill up the sink.

I happen to be near rainforest conditions, with plenty of water to go round!

[weirdstuffanimation6]

couldent u effectivly use the tubine to run a generator

[MrfixitRick]

Funny you should ask...that is in SinkScience #9, coming out shortly, where I charge a AA battery with a Subaru radiator fan motor, run backwards!

[pearljamfan99]

Isn't that what he is doing? Isn't the "shake" flashlight essentially a generator?

[MrfixitRick]

Yes, it's a generator, or more correctly, an alternator. The circuits in the flashlight change the AC to DC before charging the built-in battery. Nikola Tesla originated the AC motor and alternator, so the shakelight is kind of appropriate with the Tesla CD Turbine.

Folks have suggested different generator setups, and I will explore some of these in future videos.

[EasyQuest]

Great idea very cool^_^

[Hypocrisies]

Great video :D
