Search for turbine in Topics


I searched the engine for turbines and ventilators, cos in summer it's kinda hot here. And today my room-mate used a tool-box to keep the kitchen's door open, so that we possibly get sum air/wind coming through the kitchen's window and the corridor to cool the rooms of each one of us, but i guess i need an idea of a ventilator. Say, not a usual one like my ceiling ventilator that hardly compensates my comps' heat, but a kinda turbine that i can build and hook onto our kitchen's window. If i had more of them, i probably could stream the wind systematically through all rooms. (what i think about is a litle bit like water-pumps); air in these times is not moving, but you need air's movement to cool, so i have to get the air moving and a "kit" that you can build, eventually amplify to get a "bigger one" of the ventilators (for the main stream from the kitchen). I wanna stream my flat with air ! My room.mate went in a min ago and he said, i should try it in my room - sure, but i got my ceiling ventilator and that one sucks the air from abnove to push it downwards, but i keeps stayin the same air, cos it dun move it from outside the house to inside and out again. Umm, sry, i've drunk a lil bit and it was really a weird day today, so sorry, if it sounds weird. I just wanna get rid of the heat in here and wanna do my part as crafter against the condition as it is. So, if you got any idea, would be great...

Tesla Turbine Bike

I was curious if anyone has created an air compressed tesla turbine bike. Using a 4500 , maybe even 2 4500 carbon fiber tanks. Something along the lines of this instructable Just curious if anyone has tried this, sort of thing and if it was plausible, and how long the tanks would last or if there was some other design such as directly hooking up to the gears.

Turbine Jet engine...? Answered

If the intake turbines' speed is regulated by the compressed exhaust over the rear turbines, would it be more effecent to have 2 props in a row, or a single large one at the rear of the engine to control the rotation speed?

Wind turbine questions.

I am asking these questions on behalf of another member who has English as a second language. He is building a vertical axis wind turbine (savonius style, I think).  The mechanicals don't worry him, it's the generator and the windings. He wants to arrange six coils and six magnets.  The magnets are going to rotate with the turbine.  He has made the coils himself - each is wound clockwise, with 100 turns of wire. He assumes (and I agree) that the magnets should be separated by 60° of the circle, alternating which pole faces the coils (S-N-S-N-S-N) and the coils should also be separated by 60°. He would like to produce 12V DC, to be fed into a battery. What is the best, or most appropriate way to connect everything to achieve his goal? Links to sites that he can examine (and/or translate) at leisure would be nice.  Or sites in Turkish. (I suspect that Picoturbine documentation would help, but it's in long English.  Still, I've added it to the topic in case it is of help.)

Wind turbine placement?

I live in a rural area and we have two blue Harvestor grain silos. One has a 25 foot diameter and is 90 feet tall and the other is 4 feet from it with a 20 foot diameter and is 70 feet tall. I was wondering if it would be possible to mount a wind turbine on top of the taller one. I don't know much about turbulence though, if there would be too much? Or how high it would have to be off to clear the turbulence? This is my first try at it, I was going to try a treadmill motor, something small

Wind Turbine help?? Answered

Okay, so I'm making a small Wind Turbine to charge a couple of Rechargeable AAA batteries. But my problem is that the motor I'm using only generates voltage when moving clockwise and one of the fin designs I'm using spins it counterclockwise... So I tried a VAWT designs and it spins it clockwise but not very fast... I'll post pictures so you can see the designs. Thanks!!

Dinosaur wind turbine

I am in Kenya and being of a technical persuasion have been asked to fix this geriatric wind turbine. It is an electromagnet (as apposed to permanent magnet) based generator that my friend bought from the Italian scouts. I cannot for the life of me get anything more than about 3V from it. Has anyone ever seen anything like this before and if so have any idea where on earth I might be able to find out a little more about who made it or how I might be able to fix it. I have tried everything I can and still no cigars. Any help much appreciated. I am here setting up this organisation if anyone is interested access(hyphen)wind(dot)com

Wind turbine to charge batteries

I have a solar electric system with a battery back up for power outages.(it is also grid tie) I would like to add a wind turbine to charge the batteries in extended outages with no sun and hopefully wind ( we normally have low wind but storm outages have lots of wind). The batteries are 12 volt connected in series to produce 48 volt. Can I, should I, get a 48 volt turbine and connect direct to the batteries or some other voltage and go through the inverter like the solar panels do and if so how and what voltage turbine?.. Chris

Wind Turbine from a cordless drill?

Hi guys i have come across an old 18volt drill. i connected it to some small pvc blades about 12 inches long in the hope of generating some small amount of power. Pointed it into a reasonably stiff breeze but the blades wont turn due to the gears of the drill. Anyone out there got any ideas on how to make this work.  is there any way to free the gears so it turns easier or any advice on what size blades would be required to turn the motor. Any suggestions would be appreciated. sam301

Can you use an intermittent bursts of air to control the output RPM of a Tesla Turbine?

I've seen plenty of these projects using a constant stream of air to turn the turbine. Surely with the combination of rotational inertia and an intermittent jet of air a constant rotational force could be sustained whilst conserving the compressed air available?

variable output dc water pump for a wind generator

I'm interested in figuring out how to direct the energy produced by a wind turbine into a water pump. My goal is to pump water from a river to the top of a hill into a pond. then slowly release it through a variable water turbine so that the pond serves as a battery. i've seen pumps that work with the power take off(PTO) of a tractor that could be retrofitted if i had the right dc motor. i need to figure out what motor might work and what type of contolling i would need. also would it be better to use several smaller units that engage one at a time as the power input increases to keep the pumps closer to thier ideal operating range? The (PTO)water pump i saw operates between 17-23 hp or 20kw or less, which is perfect because the turbine is 20kw. the other thing is what if the pump operation starts at 17hp(?) then most of the power would need to be directed somewhere when producing less. maybe a series of different sized pumps and a controller to determine which pump(s) to engage to get the most water pumped.

Using a fan to drive another fan

Hi all, This may very well be a stupid question but after a quick bit of searching I cannot find an answer (which probably means it is stupid). I have been thinking about setting up a wind turbine to generate some electricity for my home. It occurred to my that it would be good if the wind turbine did not rely solely on the wind from outside so I started thinking about using another fan to blow air into the fan or fan used to create the electricity. Does anyone know if this is possible? I guess what would be ideal is if fan A was powered by the electricity produced by fan B but fan B also produced a little extra electricity that I could syphon off. This could then easily scale up to produce more power. [ fan A ] ~~~~~> [ fan B ] ~~~~~> electricity I suppose if fan A takes more energy to run than fan B can create then it won't work. Has anyone looked into this?

ceiling fan wind turbine

I am in the middle of building a ceiling fan generator/wind turbine.  I know that the electric current produced is AC (I think it's 3 has 3 wires coming out of the fan). I do not know electricity that well, and am learning as I go... I would like to use the wind turbine to drive a small garden water fountain pump that is 120 volts.  What do I need electrically to complete building this wind turbine? Does anybody have any suggestions on resources on how to connect such a device electrically?  (Do i need a diode, rectifier, ???)  Does the voltage produced by spinning the generator have to equal the volts required by the device ( small water pump)?  Thank you for any and all help as I'm trying to learn and hopefully complete this wind turbine by summer.

Wiring Multiple Turbines and PVs

Just a little worried... how do ya'll go about wiring multiple power sources together? I have been long under the assumption that your solar array will only put out power of the weakest panel. If I come across 3 different 12v panels, that have differing amperages, and have a wind turbine on a 12v car alternator, that ranges in power output, how can I wire these to make these most effective? Is there a charge controller out there that can manage multiple power sources? Pardon me if this is stupid. I just cant seem to get off the ground with these simple questions. i guess the most effective q to ask is: What do you do to wire multiple power devices of different outputs into a single battery bank/ grid tie system? Thanks so much for all yall's brilliant help. -Luke.

Turbine generator with heat pump

I got another weird idea that I like to share as I don't see me putting into reality anytime soon but someone else might do it for me after reading it ;) If you like me and call home where it is far too hot for most of the year you might have wondered how to cut the energy bills down. Especially if you in a remote area "off the grid". Sounds interesting? Then just do me the favour of posting here if you plan to put into reality and keep us updated ;) Technology has come long way and with some mirror like Mylar foil anyone can build big reflectors to use the sun for heating all sorts of things. Modern solar hot water systems are designed to produce a temp high enough to kill all harmfull stuff that might otherwise grow in our system but we can one step further: (Keep in mind it is just an idea with no prototype to proofe the concept works as expected!) Using heat pipes in a round reflector that is linked to solar tracker would allow us to boil water for as long as the sun is out there. Don't know if the flat types used for hot water systems are capable of producing steam but someone might have an old one at hand and is willing to test it on a sunny day? Anyway, assuming we can build a large enough array of solar ovens heating water pipes it is possible to drive a turbine with the steam. A linked generator of suitable size would now provide the electricity we might need to charge batteries or to power other things. But of course this would be total waste of the remaining energy in the steam! Plus we could really need some airconditioner, don't we? So in my vision we don't want to waste the water either, which mean we not only use the heat but also reuse the water to go back into the solar oven. If we now use an uscaled version of our RV fridge and instead of a heating element or a flame our remaining heat from the steam we can power a big fridge and an airconditioner on the same continous-cycle-ammonia-fridge type to cool what we need. Depending on the size and insulation rating of a house it is possible to be totally independent from the power grid during the sunny times. During the winter times the same generator can be combined with a ducted heating system where the waste heat of it is used to produce the steam we need. Of course integrating this into one unit would be the prefered option to keep the physical dimensions small. Combine all this with some good sized battery backup and inverter system and you might have enough juice to spare to make it through a cloudy day or two. Add some wind generators if you are in a suitable area to provide additional electricty. I think with new parts and some handy work it should be possible to create such a system for under $3000US. With access to some well sorted scrap yards even for free, not counting consumables, selants and so on... Sadly I don't own a house and currently not even have a garage to set up a little workshop so for now it stays an idea only... Tried to find some sponsors or at least people with interest to create something like this down here but it is like trying to explain quantum physics to a hundred year old in the retirement village. Sure, you can build something that would give me electricity and cooling for free? ... Of course it will work, so come back and show me once you made it.... If that crap could work, why are still buying fridges that run on electricty and airconditioners that drain our bank accounts?... We have 5 cooling containers outside runningon generators that use over 200liters of fuel every day and come try to tell me a steam generator can cut me fuel bills down by at least 50% if not more?... Just some of the more friendlier responses I got after trying to find some interest. Don't know if it is problem of the Aussie mentality or if I am just unable to make someone understand that we can use the scorching sun for free :( But I am not willing to give up on the idea itself, so what do you think? Oh! You have the financial means and access to create some prototype to integrate into a new cool house or  self sustaining home? Please feel free to contact me so we can start and make a living out of it ;)
