Wonderful Sir. For fixing a rough and ready cold water jacket, a deep steel plate with a suitable bore could be fixed at the top end made suitably water tight. Ice cold water could be filled in and made to drain away as it gets too hot for comfort. This will enhance the performance enormously I am sure.
~3V at ~150ma that's a useful amount of power, to recharge cell phone batteries for instance. It would be a nice addition for a camping trip. It could run nicely from the embers of a camp fire I imagine.
Outstanding, Just a thought, wouldn't turning it upside down provide a more balanced piston action for the generator as well as improve performance since heat rises? Forgive the ignorance if I am overlooking something. I do think you would need a heat insulator to cover the top hot side to force it into a certain area but, also try forcing helium in the engine by installing two valves, shutting one valve when you feel that mostly helium has taken over the space inside the engine. Of course, don't over pressurize the engine but close both valves quickly to maintain atmospheric pressure and try it out. Very cool either way.
If you took an old oil drum, drilled a lot of holes in it and inserted a bunch of these half into it, make it a simble barrel stove , you could connect all these units up and get a decent ammount of oower out of the unit.
Robert, I love your videos. However, would you be open to getting a better video camera? The quality of the cameras on any Samsung or Apple device are outstanding these days and cheap. Or, if you really want to go for it, get a Canon 5D and do your video on that and it would be extraordinary video with your already stellar content. Killer combo. I feel like I'm watching a VHS tape with your current video quality.
hiya mate - i'll have a think about it - but - i am not a video production company and when you shoot a HD video youtube downgrades the quality so it can be saved on their servers plus if i do the max quality upload it takes ages - i mean like an hour or so and to be honest I am not going to leave the computer that long to upload a HD vide - if i upload a slightly lower quality vid it takes 10 mins or so - i'm fine with that - I did a video on the quality of my videos - i haven't changed my mind much as the situation i talk about in that video hasn't changed that much - having said all of that - if I ever get anymore money from this - i will most definitely improve quality
I have a stove top fan for my wood burner... Can you do a video on how to convert one of these to also produce light with LED's while also doing job designed for?
Try winding wire by cutting out steel plates and sticking them in slits in the spool and wind your wire around them? So that they are wound more like a motor housing.
I'm here from the future to tell you that they've used free piston sterling generators to power spacecraft and perform waste heat energy recovery in many industries. These are available as relatively high output commercial devices for some time. Far from a toy demo.
Cut a hole out of a metal bowl the diameter of the engine and weld it to it and fill it with water so you have a small water bowl around the top of the engine filling with ice.
If you decide to flesh out this free piston generator I will spot you a few quid on patreon. I would like to be able to supply 2.5 to 10 watts. I have access to tools in a maker space but I would like to build something that a nomadic person could build and upgrade for themselves on the go. Since I do have access to a lathe and such I would like to build another that could sit in a trailer behind my electric bike. It would need to generate like 500 watts. Anything between 250 and 750 would be useful.
Robert, good on basic free piston concept. But for real time saw many videos in RUclips explaining only the construction focussing on alternator. Just out of curiosity, my findings, "Though gaseous expansion in the head decides motion between displacer and power piston. The spring connected to both piston plays the important role. If the elasticity of springs is not properly chosen the piston will fail." Isn't it?
In your book "alternative Stirling engines for free energy ....." page 18. The logic applied is wrong in calculating that a generator required should be of 1kw output. I installed a solar panel system of 2kw in a village in Pakistan . I did it because therefore a shortage of electricity , so we are without electricity for 10 -12 hours a day. mostly during the day time. The considerations were as follows. It is very hot in the day so I have a air conditioning unit requiring 1kw to run it. Then there is a fridge. we have a plastic tank on the roof to store water for cleaning , showering etc. in these conditions 2nd watt is used to either run the fridge , or fill the tank (1\2 hour) using electric water pump from well. the water doesn't need to be heated when showering. It is the most pleasant temperature you can imagine. The rest from the the 2nd watt is used to run TV and or recharge the four 12v lead acid batteries. In the evening the acid conditioning unit is not required , a fan with a small water tank is used which blows cool air. I hate the humidity or the warmish air of the fan. In the evening the accessories like TV and fan, lights are run on batteries which will last 4-5 hours. One tries to sleep the batteries are depleted. The cost of the system as at April 2016 is as follows. The 8 panels of 250 watt were £80 each. four 12v lead acid batteries were £111 each. The cost of uninterrupted power supply unit ( 5kw UPS) was £370. The UPS was an error , should have been hybrid so we can use the grid supply when it does come. wiring , labour , transport £200. I am looking at the Stirling generator because the solar panels can be easily stolen unlike a Stirling engine. I know you are interested in free energy , so I hope my experience is of help and interest to you on the practical challenges and considerations in installing free energy for a house in a hot climate country where sun energy is in abundance 😎.
in one of your videos you mentioned making batteries in a village in India as a small industry. i thought i would share my practical experience of solar system in a village. sorry for spell checker over riding my grammar.
having seen your videos of Stirling generator and this one ruclips.net/video/Pr6BHVhXPtc/видео.html in India. I think giving your configuration a brain like raspberrypi with sensors to control both hot end(parabolic) and cold end and pressure pump to keep optimal efficiency. I think it could be a practical device to generate 5-10 kw power for house / desalination unit in hot climate. I understand one also store heat in oil tank. Now all I need now need now is rechargeable electricity storage unit when there is no heat from sun or heat store in middle of night. (dry) rechargeable electricity store which is better than lead acid. If you know one give me tinkle to complete system.
That is the simplest and easiest to build sterling engine that I have seen yet. And best of all, the thing really works.
Fairly juicy output too! Fast more than the often seen miliamps

+Edward Vogel it's a pretty good engine

How many turns did that require to generate that kind of output please Robert?
There is very good practical reason why linear alternators are not used or produced by industry. It is limited a toy demo .
cheers

Did you finish this one?
Мне нравится слушать это классическое английское произношение 👌👍 🤗
Привет из Украины 👋🇺🇦
Try to get the Stirling to run on solar heat. Paint the bottom black and set it on a mirror. Or cds.
thanks Robert exerlent stuff as allways mate
cheers mate - glad you liked it
are you selling the sterling generator as a kit ? can i buy it please ?
I'm afraid not mate
Did you ever put the kit together?
You actually inspired me to make my generator it actually evolved into a thermoacoustic engine I designed myself check it out on my channel
how many membranes did you use?
i counted 3, a pink one, a blue and a light green or blue one
Only 2. He built it in a previous video.

where is the rest of the build?
Hi Robert that was cool
michael endall cheers mate
nicely done.
TheGEODEAHOLIC cheers mate
Just watched this. Have you seen the Sunpulse 500 (youtube)
me too, damn tired of shopping for engines and finding nothing but desktop toys!!!

please make the kit! i will volunteer with the 3d printing
:D
Wrap it in sticky-back plastic to increase efficiency by 1000%
*follows the moving coffeemug* HOW MUCH COFFEE DO U DRINK?
wonderful, any specs ?
you have to use a 2000 watt eliment to produce 3 volts ?
you have missed the point

thank you mate a very interesting post

I really thought your post was awesome mate - it gave me a lot to think about and I thank you for it
Be sure to update me please if you come up with relevant new solutions. i think your super capacitors are great and certainly relevant to my scenario.
will do mate

will do
Did you see the conductive ink videos? He makes supercapacitor batteries before the series ends for now. How's the twizy(sp?) doing?
As usual, no intention of actually running the engine...........yaaaaawn.
