from experience it doesn't treally matter it was for tuning the frequency I've bulld a air springs en the frequencygous sky high, adding springs make it vibrate faster, addjng mass wil makenit vibrate slower highestive gone was 105hz en the slowest like 10 hz for this particular oscillator, however small the friction of the spring might be it wil add drag en it works best without any drag , 0.165 bar is the minimum run pressure, stroke is about 5 to 7 mm

also making a linear generator is a nightmare

Yeah I can't wait to see what it does either, fuel monitoring is a lot more easy if you don't have a 270 lieter full hopper , im going to use the modified hatz diesel engine to measure the kw/kg , it should be way better then the Honda clone engine whit a car alternator

Its more advanced now then sergeys generator, so yes en no, it's a different design but yeah it has the 3d grille this helped getting near zero tar from the raw gas out of a stratified dual fire gasiffier , I have a 3d grille on al my gasiffiers now 😀

I appreciate your kind words, if you like to talk about stuff feel free to send me a fbook message

I take orders

No problem I hope it's of any help, sadly I put wet fuel in it so it made some tar in the gas but it makes a good comparison to the electric filter, also the secondary air nozzle inlet was clogged whit soot so it turns out it only had a single air input en relatively wet fuel 😆 still pretty good results, greetings

Still Not bad for wet fuel!

Ja goed geraden 100% kaas! , je kan altijd vragen geen probleem stuur gerust een fbook bericht, kwa locatie wij wonen in Griekenland Peloponnesos om precies te zijn , zou het heel leuk vinden als je langs komt maar dat zou het best met een goede vakantie gecombineerd moeten worden het is heerlijk weer hier gr

I appreciate your kind words, about the pdf its the most fundamental one I've ever came across it opened my eyes en made me realise most gasifiers ar getting it wrong it also tells about the (viking gasifier )that I recently replicated this one gives zero tar no matter how hard you try 😂 so make sure you watch that one to :) , I highly recommend you researching that one aswell! you can get this dual fire gasifier article pdf 3 ways. #1 make a screenshot of my thumbnail en reverse image search (this is how I got it ) #2 search for ( dual fire gasifier) on Google it should be the first or second one #3 go to the (drive on wood) site en search (2 stage) or (dual fire gasifier) first message somebody put the link in there but he got pushed down pretty quickly by some charcoal guys claiming it's better to do it like they do 😆 I'm working now on a simple en cheaper version en is a hybrid version of the viking en the dual fire gasifier for super high efficiency (1.3kw/kg+) on wet fuel so no drying is necessary! If you like cooperation feel free to send me a fbook massage, greetings en happy reading my friend!

@@oscarverwey Thank's for you answer! "hybrid version of the viking en the dual fire gasifier" - it's very interesting!))I look forward to a video about this on your channel! I finally found this PDF file by searching for an image! Even before you wrote your answer)))😎😀

That's Excellent happy reading en stay tuned 👍

Respect you from Ukraine!!!

There is no easy way, I wonder why would you want that? Wood gas is already practical , in the end there is a reason why we don't use pure hydration for powering stuff, the dilution gases that comes whit the wood gas makes it safe to handle en makes the engine not so prone to hydrogen imbritelment so I can run for a long time, de-rating is around 20 to 40% depending on certain Tunes en mods , whit 1.2/1.3bar Turbo pressure you can get back to gasoline power whit a higher conversion efficiency

I appreciate your kind words, make sure to watch the low en zero tar gasifier video's to!

Sounds like a excellent idea can you elaborate on that ? I would like to hear your ideas how this can be attached

I highly appreciated your comment, make sure you watch the zero tar gasifier video's to

No problem, its al about getting zero tar gas for the engine this can be done whit a few simple things no matter what gasifeir you have for a low price

I appreciate your comment, its al about getting tar free gas no matter what kind of gasifier you have

I appreciate your kind words, hope it was of any help , greetings

Excellent idea, although the electric filter uses 6watt for every 1.5kw electric output Worth of gas from the piston engine

@@oscarverwey "gas" um. Stirling engines do not use gas. They are heat engines. Heat difference is the only fuel used. Period. Now. I'll admit. They are far from efficient. But. Turning "waste" heat Into power.....makes sense to me

@@melvance7281 i mean to clean the amount of gas to generate 1.5kw electric the filter uses 6watt so a Stirling engine for using the heat is not that attractive so to speak, i found it very hard to make a Stirling engine en near impossible to make them delivered any significant amount of power

@@oscarverwey so. Make several. You are trying to remove a LARGE amount of heat. Stirling engines can help deliver power while doing that. And. If built correctly. Can deliver power from the heat you are trying to get rid of. We are talking ALOT of heat. That equals a good amount of power that can be harvested

@@melvance7281i agree Stirlings can do al that en are funny things , however there is a misinterpretation on my part,I don't want to get rit of a lot of heat only the micro druplets in the gas after Cooling, im reusing most heat for drying, torrefaction en pyrolizing the fuel so a low tar en even whit my new 2 stage gasifier zero tar gas is produced whit a minimum amount of added air, as far as heat dump goes only the last 60deg c ( 100deg Down to 40deg c) is rejected through the radiator or water heater , this video was juist to show the best en cheapest way i found to get zero tar gas whit any gasifier so pouple can replicate it en don't have problems whit there engines anymore

No the 2 stage gasifier only needs a dust filter ther is no tar produced at al

@@oscarverwey what mechanism is the second stage?

Stage 1 is a indirect heated charcoal producing scruw feeder it uses the heat from the producer gas en the exhaust of the engine for drying, torrefaction, steam&air superheating en pyrolizing Al by reusing waste heat from the process so no radiator is needed. Pyrolisis at low temperature (around or below bellow 500 deg c) is beneficial in the creaking stage because only primary tar is produced! the second stage consists of a ring nozzle burner that burns only some of the tar en the charcoal from the scruw feeder falls right though the burner in the reduction zone where the superheated tar, steam en co2 are reduced by the charcoal so it makes no tar whit just a little air like 0.10 equivalent ratio instead of 0.25 / 0.45, the funny thing is whitout adding any air the gas is already Cleaner then most gasifier flames I've seen on TH-cam 😂 Fun fact about the character of this machine, the gas production is proportional to the heat added to the screw feeder not by the amount of air drawn in the gasifier so the more load on the engine the more gas it makes

@@oscarverwey wow, that’s bazaar, I had no idea. Thanks for all the knowledge

No problem dude , gasification has a bad name en together we can set this right these tar making machines need to go ! I would appreciate it if you could mention me if you decide to make something approximating my design make sure you watch Al the videos I have about this machine everything is shown, good luck!

I appreciate your kind words I take that as a compliment ;) we live ofgrid so it's a necessity to use what's around instead of burning it to get rid of it

I'm glad I could be of help it's Al about sharing findings en making a better system so we can al benefit from the good stuff

I highly appreciate your effort sharing my video whit someone like that that's great 😃

They would be astonished I guess

Yes, good filtration is one of the major keys to success. Your solution is just what they need.

I hope they would recognise me for this achievement, only a electric filter is necesery for capturing a smal amount of dust

I appreciate your kind words, I'm doing my best, about the wet electrostatic precipitator I stoped using it although it works like a sunshine, the problem is the water get dirty en then you have to throw it away somewhere en this is unacceptable in this amounts , the goal is to use a ecological friendly dry system where the problems not getting bigger by adding water (think about wet en dry toilet systems), for the straightefeid gasifier the tar is so low that the dry electric filter can run for around 8 hours whitout any intervention en as it has a insert pipe now which can be replaced ore cleaned easy by a cloth ore by the flair in 1 or 2 min after stopping the gasifier because ther is stil some temperature en natural solvents in the tar so it can be wiped of easy , for the multi stage gasifier in one of the next videos I'm gonna show a dry 7 pipe dry electric filter whit moisturised air cooler, i believe it could run for day's en day's as ther is no tar anymore only some water condensation en dust this wil flow down so stay tuned, greetings

Thanks Oscar,I'll try to replicate it since I'm charcoaling rice husk at low temperature and hopefully the tar is a useful by product, for example preserving bamboo (I'm in Japan) We have a lot of both.

@@michaelgardner1681 that sounds amazing Great to hear your into gasification aswell en you likey design so much you would like to replicate it , I would appreciate it if you would mention my channel if you decide to make a video about it ;) I wonder do you produce charcoal as a product? As for tar condensation to make a liquid product I recommend that the gas is going up en out after the screw feeder in a water cooled condenser, the left over gas en tar can be burned in a annual combuster to make hot water en keep the process going 24/7 by the use of exhaust gas temperature of 400 to 500 deg c . for clean gasification it's Al about doing the pyrolisis at the lowest temperature posible en given a decent amount of time (15 to 30min inside the screw feeder) so ther is only primary tar en high quality charcoal is produced (primary tar its the smallest version of tar bond en most easy to crack)you already doing that if I understand that correctly, one can get good results whit only putting the heat of the producer gas in through the screw feeder shell make sure the diameter is not much bigger than 76mm for a good volume to area ratio,I'm the end I decided to go al the way for max efficiency for electricity production

Thankyou Oscar for your generous and helpful reply. You have inspired me to start producing content! I shall gladly mention your channel and important breakthroughs, anything I can do to support your efforts in keeping it blue! Best wishes, Michael If possible please share the details of your precipitator, I don't want to die trying just yet😅

@michaelgardner1681 i would highly appreciate that, about the dry singel stage electrostatic precipitator i wil make a other video about it en what makes it run so well, for now what i can say is *cool the gas in a radiator *Use a reflection mist eliminator *Let the gas run through a bucket of charcoal (this can be reused by drying it en after 50hours throw it back in the gasifier as it wil make more ) *The pvc parts of the electric filter consist of 2x 110mm cap 2x 110mm T peace 2x110mm female coppeler 2x reduction 110mm to 76mm 2x reduction 110mm to 40mm en 1x pipe 76mm x 600mm *The positive electrode is a 64x610mm steel pipe whit 1.5 mm wall *the negative electrode i use a stainless steel m8 Treated rot whit star washers every 70mm or so en some plastic Pipe, washers en silicone seal for electric isolation on the top, I found that a 10kv air purifier power supply whit a small 90v neo indicator light in series is sufficient to do the job en can filter gas up to 4kw electric output whit a acceptable efficiency , I will make a video about it soon so stay tuned, greetings

Hi I appreciate your comment, It turns out it was my bad ive used the wrong fuel bag whit the fresh chips after I changed the fuel it was back to normal en now whit a continuous low pressure drop,l thanks to you, I could reduce the spacing although it's a great improvement en I'm happy whit the results

Yeah It could be , we wil never for sure, what we do know is that some parts of the story's are experienced by experimentation whit the actual device, it's a powerful machine en 5psi is indeed more than enough to make a lot of damage

@@oscarverwey This is the first time i seen one actualy built and run in modern time, i can imagine the idea would be useful as a base for a lot of different applications however. If i am not wrong he did also workingh on a tranciever based on oscillations about the same time as those where constructed if i am not totaly wrong here. (The RC boat did use a coherer system if i am not wrong here, but that was probably just in order to get it work for the demonstarion i guess, still realy interesting, as far as i know there where no system using wireless coherer relay systems before, i strongly think Marconi did copy that idea from Tesla since it is nearly identical to Teslas later drawings which was more than ten years before Marconi. But, i might be wrong here... ).

You might be right on al of those things, when i build en tuned the mechanical oscillator i came to the conclusion that its the mechanical analoge of the Tesla coil en it helped me understand it fully so that's one experience you get from making en testing things , I'm doing Al kinds of experiments considering energy related devices feel free to look at the other videos, greetings

@@oscarverwey Awesome! i do my best to learn the new AI tools and i must say that i realy can't wait to see what they will be capable of in a few years if even i managed to get such stunning results with almost no training! I could not find much information about the vibration receiver unfortunately, but i did find scematics of the electric boat receiver and some much later made, but in my opinion, realy interesting British toys which used coherer receivers as RC control in the 1930s(?). BTW, i remember those old WW2 military transcievers did use actual frequency tuned slices of rock (quartz) chrystals long in the 1940s. I made a rectifier of a piece of Galena (i think pyrit or copper oxyde would probably be safer to handle but i did not had any and galena is what they did use back in the days anyway) a friend from the vintage radio association sent me the previous week in order to demonstrate the idea of the chrystal radio. (Sorry for my English, but i do my very best to improve it as i learn...) I realy look forward to look trou Your old videos!

I do use charcoal for the gasifier filter now, This is not a filter systeem anymore its a Fuel dryer

@@oscarverwey drying racks around and on a wood stove would dry fuel, real simple old skool 😉

Thats a Sure thing, although in my tiny house ther is not so much space for such things, so i made this barrel en upgraded it whit a solar air heater en a solar panel to change the battery for driving the equipment for the gasifier en the starter motor while drying Fresh chips whitnin a few days , you can see that in one of my other videos, (drying whit solar energy) this was needed because drying in the open is prone to rain en most terrible are the free chikans around the propperty XD they move the chips al over the place haha 😂

I would like that for sure

By the way i love your setup its like the drizzler gasifier, I more or less replicated that to in the more advanced version, it's more of a hybrid of the ( drizzler, spanner em the viking)

Producer gas is a different name for wood gas from a biomass gasifier, I also mix plastic in there up to 15% by weight, how clean the gas is depends on the gasifier design, I use a dual stage straightefeid gasifier it's very clean en cheap to build! It gives around 25/50mg tar per cubic meter at the raw gas output, I also use a mist eliminator en a electrostatic precipitator to remove 99.9% of the moisture en dust, what is left is 20 to 30% hydrogen, 20% CO, 1% methane en Tue rest is nitrogen, so no smoke en no pollution not even on a very rich mixture, the only modification that is beneficial is advancing the ignition by 5 to 10deg but is not necessary mine is stock , i just use 1inch bal valves to adjust the propper ait/fuel Ratio as seen in de video, of f you like to read about the dual stage straightefeid gasifier I've replicated search for ( dual fire gasifier) en click on the drive on wood page tyer is a link for the free pdf , happy reading my friend ;). I have a bunch of videos about my gasifier en filter design

​@oscarverwey thank you for your response, I appreciate your willingness to share and help, I will go threw your videos and check them out, im extremely curious and fascinated by the ability to run generator off of this gas.

@@sethtaylorm925 thanks for the kind words man that's great to hear, The purpose of my channel is to show how to do DIY ofgrid energy systems , you probably know this 3kw generator uses a awful lot of gasoline so a alternative is necessary, free waste wood en plastic is the fuel we should use to clean up Ower stuff in a carbon negative way Search for (wood gas as engine fuel.pdf) en ( development of a producer gas engine.pdf) to get most of the knowledge , together whit the dual fire gasifier pdf you have Al the knowledge to make it happen in a clean way , greetings

I'm from the Nederlands , most can hear that from the first word I say 😂

Wow, very cool. Good to see your setup with the Gasifier .

God bless you

@@oscarverwey thanks buddy, I’ll look into it

Primerly olive wood chips en some pine en oak, from my Orchard prunings so it's on the low grade fuel side whit some bark en twigs but we have a awful lot of it each season, olive wood has a lot of oil inside so I'm m sure my gasifier is a good one , it gives almost no tar for the raw gas from straightefeid gasifier en zero tar on the multistage

Although to be exact there actually 2 gasifiers on top of each other , the first Handels the wood en the second Burns the tar gas en reduce it whit the charcoal

Thanks for the advice, i think Your right I found out the same thing about the updraft air that doesn't work at least in a stable manner , pulling the gas out is indeed better for the reactions, I only did it to see where the leaks are when the engine is running it wil pull negative pressure of around 200/300mm , how cool is it to get a blue flame whitout a filter , its astonishing

@@oscarverwey if the burnt pyrolysis gas passes through the burning char it transforms into H2 and CO with a little methane. The higher the temperature of the burnt gases, the higher the percentage of gases you obtain. At high temperatures, char ash is an excellent catalyst in the methanation synthesis of CO+4H2>CH4+H2O. To power an engine you will still need to filter the gas and cool it. For a small system it would be convenient to use a heat exchanger to superheat the combustion air and a water scrubber to eliminate dust. If you want to reduce the nitrogen in the synthesis gas and increase CO you can inject a part of the engine exhaust gases onto the red-hot char bed without exceeding 17% of the air so as not to cool it. I don't know if you have solved the problem of discharging the ashes from the grate on which the char rests but if you need to ask

@@gordonpasha3126thanks for the info I highly appreciate that, the combustion air is super hot 400deg c on the outside of the pipe, the pyrolisis gas en the charcoal is already around 500deg c before any oxygen is added do to the exhaust en producer has heat, I even added a superheated steam recirculation system in the drying bucket before the screw feeder on the left over exhaust heat (250deg c ) to help whit drying , torrefaction en the pyrolises process , the empty burn chamber consumes only tar gasses to make heat so most char can he used for reduction , i hope for a high h2 content , as a final stage cooler I have a shel/tube boiler en it's connected to a 7 barrel electrostatic precipitator as a dust filter, I'm already planning to constantly feed a smal amount of exhaust gasses in the Hopper to keep the tar en moisture from condensing on the wall so I wil keep you up to date, thanks again for the info

@@gordonpasha3126 about the grate i have to modify it a bit because the updraft air is not working in a stable manner, if you have a idea i would be happy to try it , greetings

That's the plan for sure but first I need to fix the bugs so it can run continuously like a frame on wheels en en air tight lit , I wil provide the efficiency calculation in the future , best i can do is provide the wood type, moisture content en the electric en hot water output
