STIRLING ENGINE Solar Stirling Engine Compressor Conversion Solar Training

[ChuffChuffWoo]

Another huge long video and he still hasn't got it running!!!

[advthinker]

Being i have a lame o dial up service, it took 2 hrs to load and watch! did you ever get it to work? i think if you used magnalube on the crank and bore you would be impr. with the preformance. worked on test machines that had over a million strokes and the orings in the bore were not even worn. i watched because of the sphere, i have a 18 inch one, and thought that was what you were going to heat the engine with. after all you wont have to trac the sun with it. but it needs to be a clear one.

[advthinker]

What cant comment about long videos that could of got to the point in two mins instead of ten?

[stmotorsports]

Good stuff... love the cat at the end, he looks just like one of mine! Since Stirlings don't really compress air but rather just displace air internally, would I be correct in assuming that one wouldn't need to be built nearly as stout as something like this, more like pistons and cylinders could be constructed out of thin wall tubing like exhaust pipe? That way it would have a ton less mass in moving parts but also would allow both external AND internal heating and cooling on either side?

5:37  LOL . . .trying to squeeze the cra. . .OW!

[AngelGdo]

Mr. Rojas,

I'd like to thank you for all the great work that you put into your projects.

Your videos have given me tons of ideas.

Thanks,

Angel

[schr4nz]

Wouldn't it be more efficient to use a turbine system powered by steam? all the parts move one way....i would assume less energy is lost overall. ive seen a couple of videos online that show demos of high RPM turbines, they seem the way to go. would i be wrong?

[rejisseur]

Пошли вы на ХУЙ!!!!!

[weetiewildrose]

@rejisseur

Hmm i just ran this through google translator and it came up with "*@ck you to hell!!!!!"

Charming!

[SWINGREGORY]

cool

[KenMacMillan]

There are some great coatings for the inside of gas engines designed to keep the temp down. With a little strategic placement they could keep the heat in as well.

[holzpusher]

why was the whole thing done in close-up? Couldn't you back the camera off a bit? It would have made it easier to understand what you're trying to accomplish.

[SWINGREGORY]

NICE

[johthe]

Nice, I would also like to see this running.

Some suggestions I would like to see. At least 120psi of pressure. More heat and also insulation of the hot parts that is not directly heated.

More effective regeneration maybe with a small filled canister that also withstand the added pressure. Or just longer and insulated regenerator-pipe up to the hot part. Also cooling with fan or water for cold part would be nice. I hope you succeed.

[maslabud]

that chick in pink was hot

[ORIF9]

She looks like Constance Marie. :) aka Angie Lopez on the sitcom George Lopez

[veewee7764]

I have the same thing as you are talking about here. I will get photos of my setup and post them for you to see.

[regihart56]

Dan you take action on Dr. Offensive182.........dont take threats lightly..........

[GREENPOWERSCIENCE]

Thank you, I pulled his comment:-)

Best Regards and thanks again.

Dan

[luc59457]

That's a decent sized one, hope to see it in action

[FABRICIOMONTES]

she is hot

[definitionofis]

Here is some data showing steam to metal to air. Filling the chamber with water vapour instead of air, might double efficiency.

engineeringtoolbox com/overall-heat-transfer-coef­ficients-d_284.html

Here is the data for getting from inside the piston to the outer surface of the piston chamber:

Aluminum is four times more conductive than cast iron. Copper is six times more conductive

than cast iron. en wikipedia org/wiki/List_of_thermal_condu­ctivities

[definitionofis]

The cooling coefficient of different metals varies widely. I wonder if that mini-stirling engine

uses copper or aluminum instead of steel

to get a faster cooling effect.

[tangoinasia]

are there any industrial made engines? if yes, where can  get one?

[MrAndrewHall]

Hi Dan

Like the new video.

I converted the same compressor successfully - I get 300+ rpm.

I used stainless steel rather than borosilicate glass.

I also made the same structure on the cold side.

You will need to take the piston rings OFF.

Mine would not run until I substituted a single o ring.

The superb pressure sealing was needed for the compressor to reach 150 psi. It is achieved at the cost of friction.

Keep at it - it can be made to work.

[TheBattleWagon]

Can you give me the make and model number of that pump sir it looks interchangeable to some components I have been working with.

[jhobbz45]

cheesy opening

[S986S]

Random woman?

wtf?

wuteva, love these vids...

The random girl threw me off a bit though......

[YoungTubersUnited2]

i like that very last shot. good work cameraman:)

5stars

[spark300c]

make sure the can is emptied to atmosphere pressure. when the spray can get very hot the air pressure inside the spray can cause to burst.

[AlexGrim]

Black cats and crystal balls, fun, you getting a mystic angle in the show now?

[danben72]

Dan thank you I like your ideas, but could you please use the camera in a more watcher friendly way. Not moving so fast a show the whole compressor so someone can have a better idea about the whole thing.

[anyonefindAMERICA]

I thought you were in trouble with Denise after seeing that glass in your hand! LOL

[smegingbastard]

Great video! I love Denise's intro and outro! The mystic theme is also pretty neat.

[V8VRUte]

5 stars for that beautiful black cat at the end, looks just like the one i used to have when i was a kid

[rbarrell]

Hi, nice vid. Have you thought about using long threaded studs so that you could use the existing cylinder heads to hold the cylinder extension in place? That way you could take advantage of the existing tubing for the regenerator. Sort of like end caps holding the glass tube against the main body. Good luck with the project and looking forward to seeing more.

[locouk]

Is it essential to have a 100% gas tight seal on the piston? Removing 1 or more piston rings would reduce friction, making it turn more freely.

[Mrpsychotehpyro]

That depends, an atmospheric stirling engine needs not taht much of a good seal, however, such an engine will never archieve anything near an acceptible effciency.

Stirlings that use a pressurized working gas need a VERY good seal because they have to keep those 50 or more Kg/sq cm working pressure contained so well that working gas needs to be replaced like once a day at maximum.

These ones however, are efficient enoigh to compete with all the other carnot machines

[locouk]

I'm assuming friction would have been a key issue, that is why I was thinking that reducing the number of piston rings may have helped. It's a great project, I can't wait to see how this comes along.

[chessmastor]

White balance off or is that spray on tanner?

[123urpked]

what camcorder do you use to film?

[threeque]

Awesome intro, loved the crystal ball, great colors, music and camera work.

[neven01]

bah appears i spoke too soon She just did the intro, Perhaps showing more of that Beautiful Lady :)

We want to see more Denise!:)

Peace

[neven01]

humn only 315 views so far And Denise is hosting! That should boost your rating through the roof as she is A Very Beautiful Lady so watch out Dan Demand for Denise to host more often may have you doing the behind the scenes stuff:) Oh BTW I am complementing you too Dan on your excelent taste in Ladys :) So do not worry While I think your wifes attractive its showbiz nothing personal:) Awesome work keep it up!

[JULYINJULY]

HA,

I finally got a shot out, thatks.

[linuxjvm]

Hey Dan, are you educated in this thing or you just picked it up as a hobby and it grew to be this amazing? Your work is great I am still trying to figure out how you pay for your living but keep up the great job

[GREENPOWERSCIENCE]

Thanks for the nice comment. A little of both in regards to learning, the living thing, spend little:-)

This one should work good.

[neven01]

He showed us in previous Video he and Denise are both Very talented Artists

[ohmslaw111]

When

you

place the displacer cover

can you weld it or is there a simpler way?

[GREENPOWERSCIENCE]

I have tested it with high temp silicone and it does not work well. Higher pressure pops it but that is good. Trying to come up with a way to test without welding.

[lvecsey]

There are some online machine shops where you can upload a data file and they will laser cut some metal. Maybe some common items can be worked up to interface with certain well known cylinder sizes. I guess basically you need a new head with a proper seal designed for this, ideally.

[ogunshi]

Everything shown is shown for a reason. If you are teaching somebody who does not know this, you need to start at the beginning. How about rather then complaining, you produce some videos yourself about the subject for those who, like yourself, already know everything about the subject.

[ohmslaw111]

That small engine in your favorites is the exact model but smaller, you were right, this will work. Lets figure the right can, bug spray style, any ideas. If you can get off the shelf stuff, this could be the easiest conversion in the world. GREAT JOB 5 star.

Denise you are awesome;-)

[PhysicsGuerrilla]

Silly cat thinks it owns the place. Reminds me of my cat in Florida, he was black too, however a bit larger and I called him Cadilliac....Slick Black Cadilliac. He kept away from the solar trough though. I would assume his curiosity got a taste of some heat once. I hope you the family had a good holiday. Peace.

[godsend420]

[scoobydog411]

cat people are allways cool . i know i have a few

[GREENPOWERSCIENCE]

NOT CAT PEOPLE:-) We also have 6 dogs.

[zecnobot]

LOL

[JULYINJULY]

Can the displacer exhaust/transfer be on top vs the base.

BTW, I sent you that video, how about a JULY shout out;-)

[ItsMrChumley]

You need to focus on concept before technique.

Learning is living. Peace

[GetMeThere1]

I don't know....from the start, I was hoping I was going to get to enjoy some nice rackage--which has lately been missing from your vids. Instead, all I got to see was greasy compressor guts :(

[JULYINJULY]

Rackage? geeze you guys are amazing. I want to see Denise weld or build a steam engine. Guess you guys would want her to do it in a bikini.

[GetMeThere1]

Sorry, I find rackage more compelling than welding. Sue me.

[vention4wh]

I'd love to see a working Stirling engine with an automatic reflector, turning a 12 volt generator that charges the batteries on a backup power system for your house. Then as time goes on you could start moving appliances over to the backup system and eventually move most of your home's energy use to the alternate system.
