First Thank you for reading my instructable. This is a work in progress, I will be adding more and more to this instructable on how to build a steam driven turbine and power plant for your home. As always if you find any typo's or any mistakes please let me know there is a lot of information I am going to throw your way. So lets get started.

I am going to show you how I build this 45 Kilowatt Genset, or steam turbine to power my home and business.  This unit was a major effort to get off the ground. I will attempt to show you how to build this beauty.  Perhaps you can build one on a smaller scale. This unit is not for the amature. This build is very difficult and dangerous. There are a few things you need to be aware of when working with high power. 

 1. Respect the power. It will kill you in a heartbeat. 
 3. BE REALISTIC. If you don't have the equipment to build this device then send the parts out to be made. 
 4. What you don't know, ask. I will be happy to help anyone in any I can.

Always wear safety glasses and proper protection when working with electronics and steam. 

  Ok this is the turbine and generator attached together on the test stand. This is a turbine of my own design the generator portion or Technically the Alternator to be more precise is as mentioned above 45 kw  3 phase AC power output. The turbine in order to produce that level of power it required to run at an astounding 100000 rpm, thats right 100000. Now that will ruin your day if you have a major malfunction this runs at ballistic levels so if you have a destructive or catastrophic event the shrapnel will kill you. It would literally explode. This will turn you into a red mist. That said I have maintained my rpm to more respectable and safe level of around 50000 rpm my power output drops, as should be expected. Though I feel safer at that rpm. My power levels at 50k are about half of my top end of 100k so around 22 kw output 3 phase. 

  This is more that enough for my purposes. So here is the layout and break down of the genset. From right to left. The large cylinders are far right the alternator  left of that larger alum housing is the turbine chamber, the input to the turbine is via the silver high pressure line you see entering the turbine. This LIne is rated for 10000 psi at over 800 degrees. My steam unit runs at a max of 500 degrees F so i have plenty of worry room from a potential runaway. The steam unit will be discussed later right now turbine. so after we see the input line to the left of that you will see the oil pump system I have to use turbine oil rated for aircraft turbines. 150.00 per 5 gallon drum. This is great for the protection of the bearings. I am running hydrostatic bearing at the front of the turbine and a ceramic at the rear. both rated for very high rpm. The pump is a standard 110v ac motor driving a screw pump to maintain pressure at 55 psi for the hydrostatic bearing. the oil is also use to cool the alternator during runs. the oil is returned to the bath via a radiator or heat exchanger. 

just below the alternator portion on the right you can see the pressure sensor and oil filter setup, I use a standard automotive sending unit to give me my oil pressure  more on that later. In the following steps I will show you more detail for the components of the system.

the top drawer housed the control panel. This is the basic layout of the genset.

Step 1: DA Build

In this drawing you see the new design of my labyrinth seal. This device is used to allow steam to flow in only one direction inside the rotor. these two pieces stack one on top of the other with the geometry facing each other. 

Steam enters at the center and flows to the outside into the jets. the pressure builds and only allows the steam to flow to the od of the part and out the venturies. 

This is my design I was inspired by an a similar invention by Tesla. His however had issues. I made some changes and improvements and what you see here is the first layout of my design.
At first I thought you were working with 'Dead Steam' because of the 'Yellow' control valve being rated at 10,000 lbs. <br>I had a look at the video you posted and found it to be using 'Live' steam. <br>What ah relief. Not that Live steam is Any Less dangerous. <br> <br>What did you want to do with this Power Source? Operate ah Ship? <br>You should be &quot;Featured&quot; for this one. <br>Top Shelf.
wow this is complex
<p>I would suggest a flooded oil pump for this with an overflow reservoir. Your need for a primary and secondary pump to balance the system seems to be a high likelihood of failure. A flooded pump would be a pump picking up its oil from the reservoir and draining back into it. This allows for expansion and loss without adjustments. It also gives you some failure buffer. If you loose a line or have a leak the system could potentially continue oiling for as long as the reservoir has oil. Using a fluid level sensor your can include a low oil shutdown that could save you for catastrophic failure. Sizing the reservoir would largely rely on your thermal displacement and system flow rate. I would estimate a 4 qt reservoir in addition to what the system holds with a 1qt air buffer.</p>
<p>awesome instructable very good work, however the link at the bottom of your page is redirected to an Indian scammer page - your computer is infected with a virus etc.</p>
How are you coming along on this project? Do you have a working model and would you be willing to talk about your plans over the phone? I live in Michigan and am very interested in developing a home based boiler system for heating and producing power. I have been thinking of this for many years I am ready to invest to be able to produce on a production scale. Thanks Jason
<p>im around just very busy with life and other projects.</p>
<p>What's the state of this project?. <br>Was it ever built? <br>Did anyone ever build it? <br>Is sparten11 (the author) still alive? - no recent activity here.</p>
<p>im still kicking</p>
<p>I like the design, it is obvious you put a lot of thought and effort in<br> to it. It's obvious that you are a smart guy who knows things, But I do<br> have concern/gripe(?) You claim an efficiency of over 95%, is that a 95% improvement? is it 95% thermal efficiency? <br>How did you calculate this efficiency?</p><p>I ask all these questions because<br> the maximum theoretical (excludes friction and other mechanical losses)<br> Carnot efficiency I calculate for these steam conditions is about 45% (assuming 500 F hot side and 70 F cold side). I want to believe that you're reaching that 95% but unless you broke physics the thermodynamics doesn't lie.</p><p>I don't hit you with this to put you down, but because you claim to be an engineer and unsubstantiated claims like that hurt you and everyone else. </p>
<p>hi sparen </p><p>i like your project .</p><p>if you don't mind .. can i have all drawing and information please. i just want to make 3kw for my home only. please </p>
Hello my names Michael <br>I'm a retired commercial HVAC tech with my associates degree when I was 19 years old,<br>I want to say that what you have put together is great and that you have put it up for any DIY person most will not even attempt it, but it is fantastic that you are trying to give people a chance, I'm trying to put a small system together I that I can produce 10 kW per hr during the day by a solar array. I'm so tired of the utility co, socking it to us and believe every one should try their best to get off the grid and be self producing. The largest problem I can see for my self is your designs of you turbo expansion engine. You must have a lot of machinist experience, this is the part I'm not good at. How can I get the specs to get a machinist to make it for myself or can we buy it from you that you have made and just how much will it set us back the other items are very straight forward except for the rotary steam expansion engine part of it. How can I get one I will be happy to sign papers that it's your invention and I'm only able to use it for my own personal use. <br>But I want to say thank you very very much on letting all of us in on it the only way this country is going to get energy efficient is by people like your self that share what they know with each other keeping the greedy people out of the loop I would be very honored to here from you and learn from you and when I get mine up and running post it live on you tube so all can make one and get off the grid my name is Michael and you can reach me at <br>Michael190t@hotmail.com it's truly an honor to meet people of you caliber trying to help people<br>Thank you for you time <br>Sincerely <br>Michael Wilson

<p>Hi Sparten, Thank you for this instructable. My big question is, what frequency is the alternator putting out. If it's a two pole unit running at 50,000 rpm, (you made no mention of a reduction gearbox) I'm imagining it's something like 833 Hz. (I guess that also had to be balanced to run at 50,000 RPM). Do you then have to run it through a rectifier and inverter to generate 50 or 60 Hz? I didn't quite get that part of the story. You also mentioned 3 white, 3 blue and 3 red wires, one for each phase? But I don't get that either, if you have a single 3 phase motor or alternator, it's usual to have either three or six wires only. Either the ends of the windings are joined inside the alternator, and three wires come out from the junctions, or the all the starts and ends are brought out, six wires, to allow them to be joined in either either start or delta configuration. You mentioned &quot;scrubbing the power&quot;, through high power rectifiers, capacitor bank for filtering, then you &quot;rectify the three phased power&quot; (what, again??), and &quot;translate via circuitry&quot;. Then you combine the three phases into one ac output, then you use a massive transformer to bump the voltage down and increase the amps. All a bit confusing to me. Do you mean that you rectify and smooth the 3 phase AC, so you get DC, then run it through an inverter to give you 50/60 hz AC power? Does your inverter output single phase or three phase power? What voltage? Your &quot;massive transformer&quot; (at 22kw, I believe you, it would be fairly big), single or three phase? And what is the input and output voltage of that?</p><p>Kind regards,</p><p>Mike.</p>
<p>This is a really excellent project. Great innovation on the turbine.</p><p>Richard</p>
have you considered using an induction based boiler
<p>so at what point are you going to build a 5kw version and sell it via kickstarter?</p>
<p>I would like to know if this will produce 1.21 jigowatts!</p>
I am looking to put in wood burning heating in using the steam to heat my house , is there any way to using a steam generator to power the electric in the house
<p>Have you thought of using a steam generator such as they used in the Doble Series E car that is featured on the Jay Leno youtube video? There has also been an advancement in steam generation using nanoparticles. An article on it can be found at this link: </p><p><a href="http://www.technologyreview.com/news/507821/nanoparticles-make-steam-without-bringing-water-to-a-boil/" rel="nofollow">http://www.technologyreview.com/news/507821/nanopa...</a></p><p>I have no idea where one gets thees nano particles though. They used sunlight concentrated by a fresnel lens. I was wondering if something like the Doble steam generator could be modified by using lexan tubing instead of copper and using a gas lamp with a mantle inside, or several gas lamps. Perhaps this is a compilation that would nod produce any benefits. The BTU's necessary to make steam though are pretty high, so producing steam below the boiling point of water could perhaps produce some real increase in efficiency.</p>
So let's get this straight, you are using voltage out of the system to generate steam to power the system- is this correct? If so, you've just found perpetual motion!
<p>I think he might be saying that for now, he's using grid power to generate his steam for tests, and when he gets its right, he'll make it run with other fuel to become independent. Im not sure though, it puzzling me too </p>
Thats correct the current steam generator is only for dB testing.
<p>I would like to see this run, your link to the video is not working for me.</p><p>Thanks Murf!</p>
<p>can you send details of home steam turbine on Pra.gujar@gmail.com ?</p>
<p>I see kit potential here! Do you have dimensional drawings of the parts? </p><p>Here is my thought, why mess about with trying to store steam? Why not store your heat in a tank of oil and run it through a heat exchanger to flash to steam only the water you need? For that matter, if it's a closed system why not use ammonia or another low temp refridgerant? I'm thinking of a rooftop solar hot water heater configuration. </p><p>Just a thought...</p>
<p>please thank you for this project but i would like to have all the component sent to me through you.i would be gratefull if you could help me out.</p>

<p>Not one, but two readers obviously didn't pay attention before running their mouths about perpetual energy. &quot;Am I missing something?&quot; Yes. The author was quite clear that the electric steam generation was a more affordable means of testing and that for normal runs a different fuel would be employed. Improve your reading comprehension skills before posting. Good job, author.</p>
You probably already know this, but just a word of warning for any readers who decide to build something similar: <br> <br>Be *very* careful designing your boiler. Be especially careful about your selection of a safety valve, bigger is not always better. See, when you increase the pressure on the water, you increase its boiling point. It is perfectly possible to have water in your boiler that is hotter than 100C. Now you exceed your pop valve's threshold and it starts venting. If you drop the pressure too rapidly you can easily have it decrease to the point where the water is well above boiling. <br> <br>Now, when that happens, how much of the water do you think is going to flash to steam? That's right boys and girls. ALL of it. The amount of pressure generated by this happening can easily make a case of dynamite look like a 4th of July firecracker. <br> <br>The moral is: Don't just get a tank thick enough to hold ten times the pressure you plan to use and assume you're good. Make sure you know something about steam and how it behaves. Because it doesn't have to be your relief valve to set of this kind of reaction. It can just as easily be a bad bolt, or even the load you're putting on the boiler if it's not properly balanced. There are plenty of good books on the subject. Read them before you fire anything up.
Would you consider attaching the designs so that *ahem* &quot;others&quot; might follow in your footsteps? <br> <br>Also, I see the video of you testing the boiler, but have you spun up the turbine yet? (I'd be curious to see it in action!)
At the end of the instructsble is a link to my videos it is last vid bottom right. The turbine runs great. Will at to is soon very busy with new robot project at this time sorry.
Why is the boiler so overbuilt if a pop-off at only 150psi is used?
Who is &quot;John Galt&quot; :?
WOW wow wow wow WAIT! <br> <br>I've been thinking of making a low scale thermo solar generator for a while, I think that (if I got everything right) you just solved the hardest part to do so. you just have to add a solar collector to power the boiler. this is great!
Hi! <br>Am I correct in saying that you use electricity to boil water and use that steam to drive a turbine? <br>means you are using electricity to produce electricity? <br>Where can it be used then as it uses power to generate power?
The steam cell is multi fuel. The setup as you see it as stated in the instrucsble is for testing the turbine. when done the power pack is removed and the boiler is installed into a firebox. as stated it us used for testing.
what are you some kind of genius? post after post is high tech. awesome. Wish I could do half what you have done.
the rotor is really new and unique. the power unit is purchased. and customized. very much so. the whole system was built to test new rotor designs and power generation inefficiency, and look for improvements.
sorry the steam unit is for testing the turbine. it will also run multi fuel. just place the boiler in fire and steam. for emergency. no perpetual motion. the turbine i built myself new rotor design. the steam unit i build as well new design. i will post more pics of rotor and other parts.
Am I missing something? Your generator is steam powered, your steam boiler is electric powered? Trying to make a perpetual motion machine? <br> <br>Separately, did you machine your own turbine or buy components? If purchased, what and where? Same questions for the alternator.
