Stirling Engine Solar Fresnel Lens Powered Alpha Hot Air Motor Andy Ross GreenPowerScience

This Stirling Engine design from the "Andy Ross Stirling" design converts solar thermal energy into an engine with an estimated 70-100 watts of power.This is the most powerful Stirling I have ever tested and would take a finger off . IT IS NOT A TOY! This engine sounds like a gas weed eater. It destroys the false myth that STIRLING ENGINES have very little torque. THIS IS A BEAUTIFUL engine.www.greenpowerscience.com/

[@CaliforniaArchitect]

Dan, I would love to see you set up a stirling engine with a parabolic mirror, solar tracking device, and a generator. Then calculate the cost for the kWh's it generates.

[@locouk]

Poor thing was crying out for a drop of oil.

[@ParoXsitiC]

Why not actually hook it up to a generator so we can see it actually produce the watts?

[@imikewillrockyou]

Very nice sterling Dan. But keep in mind that 60 watts of almost maintenance free, silent solar power is less than $300 at amazon. However, I think solar concentrated Sterling engine power is the future and likely could be produced in a cost effective way to reach the masses. Great work Dan.

[@funkee77]

Dan, that is one of the coolest things I've seen in ages, keep up the good work, inspired me to get onto making something.

[@davidechiappetta]

I had never seen one fresnel lens so large... me has always fascinated the stirling engine, great job

[@1989s10383]

I love the idea, but am really wanting to see this step beyond the cool novelty model to something that produces a usable amount of electricity, maybe to assist in slowly charging solar batteries. I just acquired my first Fresnel Lens yesterday.

[@cyclenut]

In a world without oil, that linse and motor would be important. Thank you!

[@imikewillrockyou]

Dan, love the Sterling engine and 100 Watts is really good for something this small. These really do have solar applications that produce real energy. My only fear is people around the world might figure out they can generate all their electricity the old fashioned way with these just as easily and cost free. You burn weeds, brush ,scrap wood, trash and you name it.

[@GREENPOWERSCIENCE]

Mr. Andy Ross

[@ohmslaw111]

Thanks for showing off this cool work of art!

[@betamale3]

Is that a special torque-measuring stick?

[@GREENPOWERSCIENCE]

It has a bio organic feedback for calculating the rate of angular momentum coupled with a wooden internal dynamometer for mental calculation of joule conversion:-) JK it was just a guess when I ran the engine. The next day after filming I attached an induction motor with rare earth magnets replacing the rotor to the shaft and was about to run when the stand fell over and bent the shaft. Engine was never the same after that. Someone traded me some nice tools cabinets and small milling equipment for the the damaged engine. I told him it was broken and need repairs but he really wanted the engine. So no more videos to get a true power potential. So just a guess. Was a great engine.

[@betamale3]

GREENPOWERSCIENCE Pity, it would be nice to know how much power it produced. Where did you buy it?

[@fluchterschoen]

When he started touching it with the bit of wood I felt completely out of my depth. Way too much science with the stick.

[@johnlamarca9439]

fluchter1996 Woof Woof WOOF!!!

[@Physiogolf]

Dan and Denise, Nothing is more important than your health! With all your great videos, I believe I've never seen you wearing UV protective sunglasses. Keep up the good work... safely

[@MrNate-jd1nc]

I like how you designed a complex machine, and then poke it with a stick.

[@OverlandOne]

Excellent demonstration. Thank you for showing it. Bill

[@ubermench1000]

huh,after seeing Mr Rojas on doomsday preppers ,I sent him an email suggesting his F lens could be best put to use with a sterling engine to generate electricity. See he tried the idea with obvious success. I live in Lithia Fl and would love to get together with Mr Rojas. He's an amazing innovator ,and out of box thinker with serious skills. An idea I was given is to use electric radiator fans to circulate air through my house during shtf ,I'm going 12 volt little by little on a budget. By the time the world takes a major crap,I'd like to be somewhat able to live in a civilized manner ,its just getting there on a budget(very small budget).

[@sathancat]

I don't think I've ever heard Dan cuss before- awesome!! Way to go Dan, you rock!

[@AlexGrim]

I love watching ya work with your Stirling. It is the extra element that makes all your Fresnel Heliostatic material even more special. Stirlings are way overlooked. No load though, but that's for other vidz. You always talk about the DYI aspect, but I'm always thinking about big facilities. People look at what you do with one lens and one Stirling and miss the possiblities with massive arrays using the same concepts. I'd love to chat with you one day and see what big ideas you've formulated.

[@dannyroe7987]

seems he doesn't bother to reply

[@GREENPOWERSCIENCE]

@muddymuddymuddmann This is the production model I was telling you about:-) It may even be stronger. The sun was only 70%. Also the engine seems to like a tilt to one side. I set it up grabbed the camera and could not believe the power. How is the AF gen going. Dan

[@jacksonblaine6236]

Mr. Ross, you done it again, love the video!!!!!!!

[@vincentbeaulieu5300]

This is amazing !!! Imagine on a large scale how much torque these would produce with a double piston setup!!! ..... not to mention this works with pressure differentials and would be much more reliable because its not an explosion kicking that piston down its more of a progressive expansion ! This would be an amazing way to create green electricity !!!

[@bmw328igearhead]

Green... sure... Or use something "green" (my understanding is it's a blue glow) like a thermal source such as Pu238. Glows red hot for 200 years.

[@GREENPOWERSCIENCE]

@joshcryer :-) working on it. Flywheel is a tricky attachment.

[@chrismitchell7077]

good vid man as always :) I am thinking of trying something like this myself but bigger using a combo of Augustin Mouchot's engine and the work frank shuman

[@cgod241]

How come nobody thinks to provide a lubrication to the engine

[@zendohxd2039]

Wucifer slayer they are stupids

[@michaelgerke5854]

+Wucifer slayer Because lubrication can get into the system and cause the system to explode.

[@uawwildbob]

this is like wow but lookin at the size of the fresno lens it is probably very inefficient . buts its the best ive ever seen or heard of. great work dude

[@buffplums]

Fantastic green energy and you could use this to charge a compressed air tank so that you can store your energy for use at night. Much better than solar panels as there’s no worry about having to recycle them. Great for hot country’s

[@GREENPOWERSCIENCE]

Thanks, I have the plans for this engine. It requires a a lot of machining.

[@derbrumer6980]

Bullshit

[@buzzwerd8093]

Dan, a short fast linear stroke engine is perfect for making direct, no-bearings or seals AC power. Put it through a power rectifier and some filters and you got DC. Think of a solenoid in reverse. But with the short stroke of the Stirling and the price of 12mm x 1mm neodymium discs, I go with a plate covered with those inside a coil. The small magnet fields are intense on the plane of the plate but fall off quick, a short stroke is all it needs to produce change in the coil. V=BAN/dt or about.

[@joshcryer]

Haha, so awesome Dan. You can hardly contain your excitement. So the question is, where'd ya get it? This reminds me of "Sterling Energy System" and their SunCatcher design. I know it can work, and I dream of building my own one day (using a satellite dish as a collector, really looking forward to that rig, btw). Fantastic looking engine, though, the thermal dissipation bricks are an interesting approach (as opposed to fins).

[@KokoroDenshin]

That's look like very good torque, so tempting to apply neodymium magnets on the wheel and coil for electric generation :)

[@GREENPOWERSCIENCE]

Andy Ross, there is an article link on our website.

[@mshurance]

Dan, When can we see the plans for this engine as well as a demo of it with an actual load? GREAT WORK!

[@GREENPOWERSCIENCE]

@TahreyUK 100 watt PV is 1/4 the overall price and no moving parts.

[@timothyehook4883]

2:00 that's impressive heat from that lens. Is that open atmosphere pressure its running too!? It sounds like its kicking butt.

[@LifeFueldotTV]

badass...nice work Dan!

[@cigartist]

The obvious question is "where can I get one or who manufactures this? Have read all the coments still no info. Very curious why?

[@locouk]

Thanks Dan, A BIG Thumbs up for this video! Can you tell us the temperature of the heated part of the engine plz? I wonder because the piston will be much cooler than the cylinder and there will be alot of thermal tightening. Do you use an advanced oil additive with such temps? Oh, and can you plz do Deg C for us guy's across the pond? Cheers Bud.

[@jorgeneo560]

where did you buy it? or can you share the plans?, if you are interested in sharing you could add more info about it

[@Convict147]

This engine could make a great air fan on hot, sunny summer days :)

[@wontonsoup1389]

Thats a beautiful machine there! I was planing on making something like this to produce some electricity to make HHO gas or oxyhydrogen Which produces a very intense flame with mixing it with a little more air the temp can be brought down so it wont melt the metal,it could be used for cooking,as a "Battery" maybe even for a vehical of some kind.

[@KB8OOE]

Dan, This is Mike that sent videos on Gasification a while back. Nice Andy Ross engine. These were a limited production run and should be pressurized with @ least Helium. I'd like to clarify my stance on Stirlings.. They will produce power but they are fairly difficult to scale and materials are EXPENSIVE for the hot end. They are not readily available in large sizes and HP per LB is still fairly low. They are mostly available in marginal HP. Check out the one ( FPSE )on my page I just sold.

[@thesorehead]

Very interested to see some optimisations and power generation measurements. Considering the solar collection area, I'm not fussed if this is well under 100W - the proof of conept (namely: how easy and cheap it is to extract solar energy in a useful form) is the important thing.

[@SparrTruck]

Did you ever hook this up to a generator to figure out the output? We're also in Central Florida and are interested in building some stirling engines; curious to see how this one turned out.

[@ShiftingGlobe]

Do a segment on the history of these engines and let us know where to get one! P.S. Have you tried the focal point on that big parabolic?

[@radugeorgeoprea1949]

where do we find fresnel lenses, and stirling engine?

[@nickclarke587]

Excellent job! Where can I get drawings and castings to make this?

[@RonaldRaiden]

Its been clear as crystal all day here, I want this setup to mess with on my days off lol. Help the energy crisis, help evolve this tech

[@ProgressiveTV]

Hay Dan, another great video! I have a suggestion though. Put a socket on an electric drill motor and use that to spin the fly wheel, It will save your hands the danger. (that is if the fly wheel has a nut on the face of it.) Also, if you want tips on getting better sound, contact me for some tips. Love you videos! Peace

[@sgtoc4982]

I need an alpha Stirling Engine kit, plan or a CAD file.

[@nareon6182]

from what i can tell its a nice motor an id love to have one just the same as this one if it was on your site id buy one theres alot of people wanting this motor

[@PyroEvil]

Really impressive engine. It's pressurized ? Can you give us some specs of this engine ? Thank you for sharing this video !

[@shiftgood1]

Mr Dan Rohas (is that spelled correctly. Sorry....) SUPERIOR high profomance and most importantly exceedlying basic and cheep. This cheap and basic idea is so needed and good to know you cater to such. Hense, your a big success. Keep it up. I must speak in addition to the slow sticker on vehicles movement, part time, say something at stores movements, people should have made me their Doc., publish everywhere on trash can too, demonstrated movement, credit to my "Higher Power." Again, THE BEST!

[@brianlee9310]

Absolutely brilliant. Free energy right there.❤

[@TheGrahamBrechin]

I agree cooling the cool end will make this much more efficient and powerful

[@federicotorres3685]

it is great, would you give me the dimentions of the fresnel lens?

[@waylontmccann]

This was great. Maybe do a follow up showing the best ways to harness that kinetic force, mechanical implementation (fly wheel, belt, pulley, chain, gear/sprocket), and kinetic energy conversion to stable usable electricity formats. Ultimately I would love to see Dan Rojas work with an independent 3D design and printing group to build a modular solar energy plant, that could fit say in the back of a pick-up truck, which could be powered by said portable solar power plant, off the top my head.

[@johnconor1711]

You can use Silver plated conductors for best heat transfer and using more dishes to focus on the conductor would give more power.

[@69iron69]

Good video. You probably have thought of running a motor to turn the engine and turning it into a stirling cooler, that would be interesting. Another idea would be to get another identical engine and hook it up to that engine then you could maybe have a solar powered heat pump slash refrigerator.

[@cableairman]

@gbonesrider yeah but you could add it to existing engines and use the waste heat and the air movement to cool the cold side. Biggest problem with internal combustion engines is energy lost in heat.

[@bobrossi2958]

Is this engine a prototype, or will it be manufactured as a kit, or completed engine? I Want One.

[@kokopelli314]

Nice simple design. I wonder if you cooled the radiating plate with water if you could increase the power output?

[@jb1953oliveira]

Dan, seria possível explicar como é feita a lubrificação desse motor ? ? ? Obrigado e aguardo!

[@ElPanchito33]

Wow that's so cool Dan, Keep going, You guys are making a diference.

[@imelhac]

That engine looks wonderful, where did you get it Dan, I would want to buy it.

[@SirPayne]

Nice little engine you got there! Next you need to build a cloudbuster for the big fat thing that got between our star and your little engine :P

[@ThalassTKynn]

These aren't self starting, are they? But if you have a generator on the output shaft, you could possibly use that to kick start the stirling engine right? Kinda like a starter motor in a car, or a starter-generator in an aircraft.

[@waterkeeper03]

@MrNik1001 I'm kinda new to this stuff, he's actually magnifying the sun, that's a big magnifying lens focusing the sun on the (copper?) tube on the top cylinder. as the top tube heats the air in that cylinder expands and forces the piston down, the air is cold in the horizontal chamber and the piston sliding open creates suction and pulls itself back closed and this process repeats spinning wheel Part i don't understand is the connection between the 2 chambers. Sorry If I got any of that wrong

[@SavageSanDiego2012]

Where can I buy that?

[@Migueldeservantes]

what happen if you put oils on the moving parts! like piston and cam shafts? will this damage this kind of engine?

[@jkcarroll]

OK. We get it. It runs. Now could you provide some info such as where to buy the engine or get plans to build it; what was your setup to heat the engine, etc.

[@Can101276]

Awesome find Dan, where can I get one and How much?? Do you have an estimated operating temperature for this test? I want one!!

[@Mongoswede]

The company is called Infinia Corp and they have a 2.2Kw Solar generator and a 3.2KW iirc. They are not offering them for individual sale at the moment...just large power installations.

[@ParadoxPerspective]

Fresnel melting lead or another metal that gets stored in an insulated box. Heat exchanger directly to the stirling engine's head. Bottom of engine heat sinked into water reservoir to passively heat water. Have you ever played around with Nitinol? I'll send you some!

[@GREENPOWERSCIENCE]

The catalytic converter requires a certain temp to prevent catalyst poisoning which is the buildup of certain contaminants coating the internal surface area. While a Stirling engine would not draw enough heat to cause this issue there is a limit and 3 HP would be a serious engine. TEG technology advancements may offer a solid state alternative.

[@sjh7132]

@directrix1 I agree it should be measured. No matter how much power it makes, I would expect the RPMs to drop if you go from no load to some load.

[@dcox01]

Dan That is too cool. Great video. Keep us up dated please.

[@JB-wx4wo]

You're on the right track friend👍

[@bossyhannon]

hey dan. love your videos and thanks very much,. i have 2 questions. one is . is it difficult to track with the sun?. is there a device for this and also i have seen a video selling me the stirling engine but is it really good enough to hook to a domestic supply on an ongoing basis, the presentation suggested that it could generate 120% of household needs but almost all stirlings i have seen have little output.they seem rather small and seem to need the sun or else a seperate heat generator.

[@jenniferlollar1099]

How would you apply the stirling engine for powering house air conditioning?

[@shaunmc3433]

Hi Dan, You mentioned that it can produce between 100 and 150 watts. Do you happen to know how that level of power compares to a solar panel of approximately the same size as the lens you are using? Thanks.

[@mker16]

Congratulations, very nice work. Continue ......

[@ROBK636]

I herd something like this several years ago. A sterling engine at the focal point on a large mirrored motorized dish. They marketed it at 10kw and where to sell for around $10-15k have not herd about them for a wile now.

[@patrickrocillo2602]

Fantastic Device .... Amazing to See It....

[@johnclarke7938]

Perhaps Bolt some extra weight onto the flywheel if you want to do something usefull with the power? or even put a gearbox onto it and hang a BIG flywheel on it?? Fantastic Motor Did you buy it ?as I to havnot got the engineering tools to build one but am desperate to get of the grid.Thanks for shareing

[@Robots-and-androids]

So when do you hook up a generator to it?

[@RawVisualsVj]

I spose you could connect it to a gear box to drive things and maybe a solar tracker for the fresnel to keep the sun focused on it. Nice bit of kit :)

[@101blender]

Are you going to be selling or giving out plans for this engine? Seems quite powerful and potentially quite helpful.

[@arthurmunoz3597]

The reduction of power is clearly noticable, when the sun both lowers in the sky, and when blocked by the clouds. Although, I did expect that you might explain at least some aspects, involving the functionality of your solar powered device. That's for sure.

[@haxenophon]

@footfixer You could indeed run it by cooling one side and leaving the other side at "room temperature". Of course you can run these things on waste, however the efficiency of a heat cycle is proportional to the temperature difference between the hot and cold side.

[@JevinDeml]

You have to keep rotating the mirror to follow the Sun during the day?

[@workinalday4351]

I like it, it's a nice and simple design.

[@tomterahedrob]

Could you get one of these to run off the heat of a wood stove and get more of the stoves heat into the house by distributing more of the stoves heat?

[@meagain2222]

The sun input power is about 1000 watts per sq. meter. At 10 % conversion or 100 watts that would need a one square meter lens.

[@joecam905]

tell us how to get one please.this works great.thanks for your great work

[@keithbrier4397]

Nice work!!

[@WaltRBuck]

Wonder if you could use this thing to power a cathode anode source for the separation of oxygen and hydrogen for fuel, and at what rate or if it'd be a viable source to continue going for a while under the right conditions.

[@Scottthebigbloke]

Hi Dan great work, where can i get one of these engines and a lens please, i need to pump water at a slow rate so would love to try this running it or onto a generator then pond pump

[@EdgeRetro]

that's neat. up to now I had assumed they were impractical toys. First time seeing anything that would make me think otherwise. Do you imagine it would hold up for long term under a load - or would it need a lot of maintenance and part replacement?

[@sjh7132]

I'd love to see that thing turning a DC motor and lighting a 100watt bulb (or a bunch of smaller 12v bulbs) Is it able to get rid of all the necessary heat or will it eventually lose efficiency because it can't cool the air? It doesn't seem to have any big radiators.
