My micro turgo turbine and car alternator

[usmcoth]

Great. In what you gain in electric you have wasted in water.

[douro20]

Turgos are very efficient, but very noisy like all impulse turbines.

[SmallWindTurbines]

Nifty gadget but long way from powering a house right?

[albybe97]

sorry..in which mountain house is used this generator?

[energieag]

@albybe97

ciao

sono italiano

in val d'ossola

[fukpolitics1]

mate thats a phat idea ! well done. what would that power TV ,COOKER? do you charge a battery or is it direct? how many of these would you need to power your hole house?. wb

[energieag]

I want to explain that this is not the water distribution network. hydroelectric plants, you can do only if you have a natural stream.

[IcechickenSr]

@LUCKY4908 that would be counterproductive now wouldn't it, not to mention a serious irresponsibility to our enviroment. He's using a gravity feed from a local creek. Our farm has a gravity feed sprinkler system from 4" pipe all the way down to 1/2" in places. Due to the large down hil run and the siphon effect we get a massive ammount of pressure, which is more than enough to run several units such as these 24/7 with no issues what so ever. The has also stated he's NOT using public water!!!!!!

[IcechickenSr]

@LUCKY4908 I did, but below in the comments he made 1 year ago He also stated he's not using public water and running it from a mountain farm home or similar. A creeak is not the issue, it's Water, gravity, weight, speed and restriction that can create a massive ammount of power. If you drop so much water from 100' how much force do you think your going to have to play with, I could give you exact math, it'd blow your mind. We run a whol sprinkler system like this. Cheers mate.

[IcechickenSr]

@LUCKY4908 Hey mate, Sorry if I provoked you in any way my intention wasn't to try to be right, I just noticed this pop up in the comments alot and thought I'd pick one of them to help the author address the question/concerns. Thats all I mean by our conversation. It's really a nifty little device to setup if you have the abillity to gravity feed water from a creek down a slop long enough to allow alot of water and it's combined weight in volume to drive a small turbine. Emerg power. Cheers, IC

[LUCKY4908]

@IcechickenSr no problem.

[cherokeewitfibt12]

those r the worst welds i have ever seen

[wow1022]

where do u get such water pressure?

[davepamn]

How many amps does the alterator generate?

[energieag]

32 amp

[davepamn]

How could the design be enhanced to produce kilowatts of power and at what cost?

[762gunr]

@energieag 14V X 32A = 416W. That's alot of power if it runs 24/7.

[davepamn]

@davepamn What is the water flow rate? How many feet does the water flow down and at what rate does the water enter the generator?

[videocruzer]

@davepamn i have seen 36v 300amp units.

[taztaz79]

Well a grid tie inverter for that sollution and you can put all your generated electricity on to the grid :)

[johnnecron]

The big question here is

Can you deisign such a sysytem for your home that will serve as an emergency generator power supply in the event you lose your electricity by using the public water supply for your power source and then storing your electricity in a bank of batteries and then get your ac from an inverter. Now here is the big question.

how many gallons of water per hour to run the generator .

how much money per hour in water fees.

how many kilowatts pr hour and the money value vs water

[energieag]

@johnnecron I do not use tap water

Use a natural stream

can not think of using tap water to generate electricity!

[shiikis]

@energieag Consider taping into the water line coming into the house AFTER the water meter, so anytime water is used in the house, current is produced, then either pushed back into the grid to spin back the electric meter or to a bank of batteries.

[swis19]

Nice weld.

[shigeno389]

nice.. earth saver idea..

[fingerspies]

I want one of these Turgo turbines but i don't have a water supply :( can i still buy one though and connect it to the prop shaft on my fiesta and then connect the turbine to an alternator and also to the cars speedometer? i can then see if i can get it to go off the clock...

[Kenzofeis]

As a "car" generator is 3-phase, one could use a feed-line regulator to stabilize rpm and a 3-phase transformer and rectifier to make 3-phase 220Vdc, do NOT connect that to the grid... but, it can be used for heaters and filament lamps, these does not care as long as the rms voltage is suitable.

AC motors, TV's, refrigerators.. they will usually demand 220-240Vac 50/60Hz.

However, there is 12Vdc (14Vdc) lamps and heaters available, even coffemachines (camper gear). Money saved.

[electrique527]

@Kenzofeis :

No need for all that. Get a 3 phase 230 V motor, and use that at slightly above the rated RPM.

You will get 230 volts instantly. :)

Yes, need to regulate the speed, but thats not so hard. An electrical valve in the feed line, and a little bit of eletronics.

Its all out there already :)

[EricSerenaKnutsonCov]

tell me more about this

[sigmundphreud]

How do the bearings hold up to the inverted position?

I would think they were not engineered for

the stress caused by inverting the alternator....Have you adapted the shaft in some manner?

[stdavross666]

@sigmundphreud you wouldnt think the bearings would wear since the pressure of the belt on the alternator in a automotive situation. There would be no pressure on the bearings in this situation i would think.

[snuffying]

can i use a vacuum cleaner motor as a turbine ? i think it will work pretty well, its about the half size of this alternator

[animebsd]

no becaus the motor in the vacuum is a universal motor

u caqn pull the fan out and hook it to a generator .

u just cant use a vacuum motor to pruduce energy

[peltontrain95]

ciao, una curiosità, hai idea di quanto costi prendere una concessione per un micro hidro su un fossetto da 10 litri/s?

[kakureru]

you can modify the alternator to be more purposed for what you need if that turbine can put out the torque

[billykash]

You know what would be really cool!? If you showed us how you made this!

[2Cweed]

There are military surplus truck alternators available that output 100A @ 24V. Some already have 110VAC available without modification.

[Fentanyl3]

Do you have and model or type names that comes to mind? I'd be fairly interested in an alternator that is already wound for 120V operation.

[happyguy82]

if you want a 110VAC alternator just rip it out of a small generator.

[mpwelk]

Italy... i'm full of envy to be a tinkerer in Italy...

[Ezlife2]

what is the water pressure. city house water is 25 psi

[energieag]

i live in the montain of itay.

i have a natural fall.

you can not use a water city house.

it is not possibile!!!

[kargaroc386]

@energieag in other words, you're screwed

[GooseThunderfoot]

@energieag While I was taking a Wind and Micro Hydro class last semester, my professor said that some people were actually trying to generate electricity using the utility's water pressure. Pretty ridiculous stuff.

[ak2600]

what pressure did you release ?

[Cassiiir]

great man!!!!!

what type of turbine are you using? and how much water does it need? and how much Power do you get from it???

but its a great video!!!!!!!!

greetz from austria

[HelpSaveTheEarth2051]

Can i use a car alternator as a wind generator if i attach a large fan to it?If so is there any way to convert this power to ac and use it in my home?What is the largest size batteries suitable for a car alternator that can chagre in a days time?

[energieag]

is very difficult to use a car alternator for a wind generator.

do not recommend it!

You MUST put a multiplier of RPM.

you need to use a PMA

[HelpSaveTheEarth2051]

multiplier of rpm? hmmm i am guessing the gear system in a bike (chain and axle) will be suffcient?

[fenixxl]

Monofasic engine will be better the car alternator has more mantenience

[Mostlyfun]

Brother, don't fret what the engneer is crying about just google windbluepower and you will have the answers to all your questions.

[Fentanyl3]

A car alternator already produces AC current, it is rectified to DC for your car. take the diode trio out and you have 3 phase ac at about 16 volts. you could either step that up, or run several gear driven alternators(to maintain phase synchronicity) in series to produce 240V

You can also flood the exciter coils and produce about 3 to 50 volts, but it will overheat the alternator rather quickly.

[HelpSaveTheEarth2051]

Yes but i want power that can store to a battery to be saved for later use (night time)All i need is 110 volts because thats what all electronics where i live use.Maybe you can help me...btw thanks for bothering to reply when no one else did... :)

[Fentanyl3]

Well, then you have to make your choice, AC or DC

Batteries are DC, and the best bet, as they can store power for use later or in larger amounts than what can be generated. As you desire.

Use an alternator with the trio in place to charge your DC batteries, then use an AC inverter to produce the 110V ac

Google Inverter and you get a plethora of results

[werkloosdoorcrisis]

Fentanyl3, you seem to know a lot about electronics. If I take a car alternater and have a savonius rotor spin it will it produce 12V from a certain rpm or will the voltage increase when the rpm rises? In other words, can I charge a battery directly from the alternater? As far as I understand there is something in the alternater "producing" 12VDC regardless of the rpm. Is that correct?

Thanks.

[Fentanyl3]

Well, if the alternator is internally regulated, (most are now) the alternator will output around 13 to 15 volts at around 500 - 1000 rpm depending on the manufacturer and application. they will continue to output relatively the same voltage up to about 8000 rpm. If you remove the regulator and manually excite the coils with a set voltage then the output will vary with RPM, and with the amount of excitation voltage. Message me and I can explain more.

[werkloosdoorcrisis]

Thanks, I will send you a PM soon. I'm making a list of what I want and need. Power desire is 1000W (at 230VAC 50Hz sinus) for at least 12h/day to power my home office. Energy used by: PC screen Laptop Printer radio fan light I'm looking for an inverter 12/24VDC => 230VAC which will automatically switch to the power grid as soon as the battery voltage gets to low and after X hours will switch back to the battery. Just one of the challenges.

[Fentanyl3]

A car alternator is definitely not the way to go if you need that much power.Unless you purchase one of those high performance alternators built for extremely loud and useless sound systems. your typical car alternator can only produce 700 to 800 W at 12 volts, that's only 80W at 120 and 40 W at 240, that's not figuring in power loss due to inefficiencies.

[werkloosdoorcrisis]

I was thinking of making a stack of battery's from a truck 24VDC with sufficient capacity. The turbine can charge them 24h/day (when the wind is blowing) and when full I should be able to use is for 12h.

At least that's the idea.

I need (at max power) 4,35amps secondary

At 24V that is 42amps/0,85=49amps

(0,85 is the efficiency of the inverter)

12x49=588 Ah capacity of the battery stack. I have to check if the battery can handle 50amps continually.

Am I getting there?

[werkloosdoorcrisis]

I have done some calculations of the power "produced" and it will not be a succes.

A double stepped savonius rotor (88cm dia, 176cm length) will deliver about 30W when the wind speed is 5m/s.

Sadly not worth the investment and trouble.

Thanks for you replies though.

[Scottthebigbloke]

Hi can i call you for a gossip, as im just about to go the 24v truck alternator route into a wind turbine ! eek !

[CmdrTobs]

Why is that only 80W at 120Volts? and 40Watts at 240?

Can you explain that reckoning, I have heard other say this tin.

[sigmundphreud]

Voltage is "pressure" behind the current,

as you increase voltage current needed is lessened. The higher the Volts=the lower the current.

Ohms Law is handy to figure your power needs for any given circuit P=I*E.

1. P=Watts

2.. I=Amps

3. E=Volts

[CmdrTobs]

I really have to disagree with Fentanyl3 2x car alternators are perfect. They will get that easy. Rectify and de-ripple then use to power a a 1 KW Grid tied inverter (expensive, but too hard to make).

No need for battery's. If it produces more than you need it sends your meter backwards. If not enough it supplements you houses 'grid' as much as possible.

With government Subs for clean generation you could claim a £50-100 a year on top of whatever you sell back to the electricity comp.

[CmdrTobs]

I think you got that slightly wrong. "fooding the exciter coils" would not change the the voltage produced. It would only increase the the current produced which would lead to more heat.....

To get a car alternator to get out 110V, you just have to modify the regulator circuitry and give it above standard RPM. If only someone could be bothered to spice one..... Still no point as the AC freq would be all wrong Unless you stick with lighting only.

[kleetus92]

You're best bet would be to convert it to DC, then feed back through an inverter to get back to a constant 60HZ, or 50 depending on where you're at. Can't say what the efficiency would be though. Most alternators won't get you 110 unless you 4x the input speed and really put the field to it. In any event you're well past redline for a given design. You'd be further ahead to modify an induction, or universal motor.

[REGreenTeam]

It is not very economical to use a pressure washer to drive a hydroturbine now is it. Maybe you can get that much pressure at Niagra Falls !

[autograssboy]

also what happened the noise stoped is that because the battery is fully charged?

[autograssboy]

hi nice iam new to all this just wondering should i use a alternator or a Dynamo?? please help regards mark

[inventhead]

the water flow looks too slow for an alternator to spin more like a water pump using alternator as a motor aah ever try to turn an alternator by hand when rotor is energized u cant stiff as a board u need hp tourqe dont think soo

[Funker1969]

it,s easy

[davidjasbridge]

alternators dont work unless you put a little charge to the excitor first, just check out davidsfarm, if you disagree.

[oisiaa]

lol, davidsfarm is now an irrefutable source of information!

[animebsd]

well dave roks!!!!!!!!!!  and its his last name lol

[teedot]

@oisiaa davidsfarm is nothing but a bunch of pedophiles!

[rotorsk]

well there is self exciting alts like the 10si 25si 19 si and so on.

[wind4watts]

Yep, just a little then it provides it's own for as long as it's spinning.

[wind4watts]

Yep, with sufficient water/ turbine torque power and with 3,000 odd rpm modern alternators will / could deliver 100-130 amps = 1.4-1.9 Kwatt, bigger turbine rotors anybody?

[wind4watts]

How much power have u had from this set up?,a lot less spray / noise on this set up than a tripod.

[energieag]

the power is 180 watts.

The power depends on the net head and the amount of water available.

Of course, even on the efficiency of the system.

[gmaclaren]

Please buy a tripod and use it.

Thanks.

[TruckerTim76]

diddo on the tripod

[wind4watts]

Tripod! lol , obviously you cannot even change a fuse if you think that would work, you would be totally drenched in 5 seconds.

[MegaMeaty]

wait, lets see a lightbulb with a ammeter pls-

lol

[paulmelius]

can i use a car alternator for a wind turbine without modifing it

[energieag]

you can not use a car alternator wind generator.

You can use a permanent magnet generator

[wind4watts]

Not normally they need about 1800-2200 rpm to work well, CAN be done if you gear it up about 10:1, got allow bigger prop for gearing losses pmg's are overpriced so can be worth buying bearings cogs etc, seen a geared up 3kw 230volt on here that uses big rotor. worked great!.

[sum1uallno]

?????????????

[cotton509]

make it so it uses the same water all the time so it works more effecently

[natony0please]

how much water pressure do you think your getting from your water outer to the blade?

what kind of blade age you using?

[energieag]

the water pressure determine the rpm generator.

the water presure x water flow x 9,81 = power

i have some documentation

send me your e-mail

ciao

[snowypetrel]

Alternators have much higher resistance when electricity is taken from them instead of running with no load. With a diesel engine running the revs go right down when current is actually drawn from the alternator, such as switching on an invertor which draws quite a lot of amps.

[35naves]

wow ! where did u buy the pelton turbine.

I live in the woods I need it,,, do You sell it?

[nbm34]

35naves ... I believe if you get a number of spoons and use the heads attached to a wheel by

weld or screwes or holes in the wheel to put them in you need as many spoons as the circumference of the disc can hold for the water jet or steam to hit the spoon heads. These are a cheap and effective way to build your own pelton wheel.

[haikael]

what diameter size for your turgo turbine?

[energieag]

190 mm external diameter

[johnta264]

that's not worth the trouble. all you get out is enough energy to power 1 light bulb. you need a bigger generator.

[tsport100]

Simple ohms law.

A 100 amp car alternator will put out 1.2 kw.

Now, how many light bulbs is that??

[johnta264]

that was a figure of speech. what i'm saying is, your turbine should be big enough to run a bigger generator. 5000 amps would mean something.

[tsport100]

Actually, I'll correct myself,

Car alternators put out 13.8 volts some SUVs come standard with 160 amp alternators and High output are available up to 250 amps. That's 2.2kw - 3.5kw. Your average house draws about 1kw/h all day. I think you're confusing amps for watts.

[johnta264]

Are you saying that you run your house on that one alternator? I remember reading about how many watts appliances use, You can look it up. I'm not exact here, but a refrigerator uses about 1200 watts, tv 600 watts, a whole house would use about 8000 watts. A 160 amp alternator puts out, I forgot, maybe you can tell me, but I don't think is is that much.

[tsport100]

It's watts over time kilowatts per hour. You do know what a kw is don't you?

Just look at your power bill, it says exactly how many kw/hr you use. I don't know about you but my bill comes in at 24 kw/h per day, so that's a load of 1kw every hour of the day and I have tons of machinery in a workshop downstairs so it's not just the fridge and ac!

[johnta264]

So are you saying that that little alternator can run your whole house?

[tsport100]

It's not my video!!

But IF the bloke who made this video can keep the alternator at peak rpm under full load with his gravity fed water supply then it will be putting out 13.8v x 160 amps = 2208 watts, or 2.2Kw x 24/7. More than enough.

[johnta264]

So if I want to run my house on batteries and dc/ac adapters, can I keep the batteries charged with one alternator?

[tsport100]

Yes! Better idea is to get a grid connected inverter so you can forget about batteries etc. It'll share peak loads with the grid, turn your meter backwards and perhaps earn credits.

The ACTUAL challenge is to find enough CONSTANT power to turn the alternator at full load... 2.2kw = 3 horse power!

[johnta264]

I've been working on that for a while. One day, hopefully. thanks for info!

[Darkfoster22]

Alternator wood burn up

[nbm34]

If necersary you can connect three alternators or four if necersary to a belt system driven BY one TESSLA TURBINE FIXED TO A CAR FLYWHEEL DRIVEN IN MY CASE BY COMPRESSED AIR.

[douro20]

Turgos are very efficient; some designs can reach over 90% efficiency.

[wanshei]

who sez americans r dumb?

[brophildotNET]

Sounds like there's not enough torque to overcome exitation; Be sure to regulate exitation current, those little alternators can produce many volts. If you have, say, a 6" dia. pelton turbine you might need 16 lbs of force @ 1800rpm in the cups to produce 14VDC @ 75A.

[energieag]

The diameter turbine is dependent upon the net head and turns that you want to do.

That was only a test.

Mounting the proper nozzle is generated power right

[haikael]

Brilliant...marvelous...you my idol...dude, can u teach me how that things work.

[energieag]

I have not understood your problem.

But if you want to feed the generator with a pump, and then to off the pump and to think that the system self feeds this it is not possible!

An alternator begins to generate over the 800 rpm.

The turns are determine from the diameter turbine to you and net head (the 10 m=1bar).

The power that you can generate depends on how many liters to the water second.

P(w)= net head (m) x Q (l/sec) x 9,81g.

a car alternator have a render approximately of 30%.

[haikael]

thanks...Before this my system using alternator is unsuccessful cause i don't get enough speed..I get 3000rpm at free running(with no field current). But when field current, the speed decrease to 500 rpm..Alternator begins generate at 800rpm..The water pressure from my system is 3bar..So i only get 500rpm..After my calculation, to get 3000rpm(with field current) i need about 18 bar..

[haikael]

So my new design is using water jet as prime mover..Do you think it's possible if i use water jet as prime mover to hit the turbine? Water jet pressure that i use is max 30 bar and flow rate 17liter/minutes..
