HELLO, MY NAME IS RAY. I WENT TO YOUR CHANNEL AND I SAW THAT YU ARE A FARMER, WELL LET ME TELL YOU THAT IM A NATURAL FARMER. MAYBE YOU KNOW THAT NATURAL FARMING AND ORGANIC FARMING IS A LITTLE DIFFERENT BECAUSE IN ORGANIC FARMING THEY STILL USING CHEMICAL INGREDIENTS LIKE Ca, K, ET., BUT IN NATURAL FARMING WE DON'T USE THAT, WE MAKE OUR OWN INPUTS, FOR EXAMPLE, FOR Ca, WE USE EGGSHELLS, ANIMAL BONES, ETC, FOR K, WE USE BANANA PEELS, ETC., THAT WE PROCESS WITH OTHER SOLUTIONS AND AFTER WE DISSOLVE IT IN WATER AND APPLY TO OUR CROPS. I HAVE THE PRIVILEGE TO LEARN FROM A COUPLE WHO WORKS FOR MY GRANDPA IN HIS FARM AND THEY TEACH ME THIS INCREDIBLE SCIENCE THAT IS NATURAL FARMING, HE WAS FROM JAPAN AND SHE WAS FROM KOREA, SHE WAS THE MASTERMIND AT OUR FARM. WELL, YOU MAY ASK YOURSELF WHY IS IM TELLING YOU ALL THIS? BECAUSE I THINK I CAN HELP YOU GIVING YOU SOME IDEAS FOR WINTER TIME LIKE MY GRANDFATHER DID IN ITALY IN WINTER TIME TO KEEP PRODUCING HIS CROPS AT HIS FARM, HOW? VERY SIMPLE WITH A ROCKET STOVE/HEATER IN AN UNDERGROUND OR REGULAR GREENHOUSE, VERY SIMPLE TO MAKE AND VERY EFFECTIVE TO GROW CROPS, RAISE ANY KIND OF ANIMAL IN WINTER. MOST OF THE PEOPLE CALL ROCKET STOVE BUT THEY DIDN'T USE THE RIGHT WAY TO MAKE IT, BECAUSE IN THE ROCKET STOVE YOU BURN THE WOOD UPSIDE NOT HORIZONTAL LIKE EVERYBODY DO, WITH THIS METHOD YOU BURN 1/3 LESS WOOD THAT THE REGULAR WOOD STOVE USE, THAT IS WHAT THIS GUY IS DOING HERE A REGULAR WOOD STOVE AND CALL IT ROCKET STOVE. AT THE ROCKET STOVE YOU CAN COOK AND YOU CAN HEAT YOUR HOUSE TOO, EVEN YOU CAN MAKE A SYSTEM TO HEAT THE ENTIRE GREENHOUSE. HERE I WRITE THIS WEB PAGE WHERE YOU WILL FOUND A LOT OF IDEAS FOR YOU. insteading.com/blog/rocket-mass-heaters/ HOPE THIS HELP YOU AND HELP YOUR PEOPLE MORE IN THE FUTURE WITH YOUR WINTER PROJECTS!!! PLEASE CONTACT ME, I WANT TO BE YOUR FRIEND AND WE CAN EXCHANGE IDEAS ABOUT FARMING, AND TOU CAN TELL ME WHAT PART OF JAPAN YOU ARE FROM, WHAT VEGETABLES YOU GROW? DO YOU GROW SPROUTS, MICRO/BABY GREENS? DO YOU RAISE ANY ANIMALS? DO YOU MAKE YOUR COMPOST? DO YOU KNOW THAT CHICKENS MAKE THE BEST COMPOST IN THE WORLD? AND YOU CAN FEED THEM COLLECTING FRESH FOOD WASTE FROM RESTAURANTS AND YOU DON'T HAVE TO SPEND A YEN TO FEED THEM? DO YOU RAISE WORMS FOR FERTILIZERS? DO YOU USE MICROORGANISMS FOR YOUR CROPS?

This is a great option for night time showering. It would be awesome if you had a combination rocket stove / solar pop can heater hooked up to your shower. Then you could heat with the sun during the day and with the stove at night!

[@ngqobilezikhali6871]

This is actualy a brilliant idea with a functional prototype. You could also use copper pipe instead of flexible hoses joined to your coil embedded in the stove and add some legging onto it to retain as much heat as possible, also have a larger vertical insulated reservoir tank that will help in retaining the warm temperature while easily homogenising your heated water inside the tank through the heat siphoning action. Great ideas bro!👌

This is a great build! Thanks for sharing! Note though, the teflon tape you are using needs to be threaded over - meaning the direction you wrap it matters. if you wrap in the wrong direction, the threads might push the tape backward and roll up little holes and pockets between the threads.

[@johnsantiago1872]

Not only longer copper coils, but a metal tank reservoir on top of the rocket stove. Also the hot entering at the bottom, so that as the hot water rises, it will disperse the energy through out the tank. It might require a check valve on the lower tank inlet in order to start the siphon.

[@davidsnow9453]

Well overall I think it was a good experiment. I learned a lot and consider it a success and thank you for the content. I think to often when we experiment with ways of achieving an alternative to what we readily have in modern conveniences, we focus to much on trying to recreate an absolute equal result to what we get with those modern conviences, and in the process we tend to way over think thing's and that is where we start complicating the process. My personal approach to such experiments and invention dabbling is from an prep'r survivalist approach. In an grid down type survival scenario thing's just aren't going to be as cozy cushy comfortable as what we are used to. But with ideas such as your cob rocket stove and water heater shower we can definitely have a little more comfort than going down to the cold creek to wash up everyday in a shtf situation.

[@weekendlovinggypsy1737]

That's great, can have the tank on top of a van roof and have the rest stored in a tub until you need to hook and use.

[@GreenShortzDIY]

Great idea for application. Perhaps a different rocket stove instead of the cobb...aircrete would be a perfect option for lightness and rigidity...but your concept would work great. Thanks for watching, WLG. :-)

[@psychologicalwarfarev2kgan46]

A more efficient way of fueling is to have a vertical feed box with a horizontal chimney. Long 4x4's or similar wood cuttings are fed into the feed box so the fire feeds itself. The heat is forced horizonally over the coils and out a stove pipe.

[@celticphox]

Just curious, but is there a way to incline your fuel grate to allow gravity to pull the wood downward rather than having to continuously pushing the fuel in?

[@GinaKayLandis]

Mixing valve for hot/cold water? Cold (ambient temp) water could be in a 55 gal elevated drum. Too hot water would be a concern.

Hi. THis might be a better comment on the first vid, but I'm here now :) For a rocket system on all the mass heaters I have seen online they are takign the heat out at the top instead of in the middle. Was having the heat coil in the middle because it was easier to build? Putting the coil at the top would let you get all the heat from the flame you had in the chimney too ? It's great to see how you experiment and tinker with these things.

[@joriswagter8516]

Looking good. Just a little tip: be sure to wind the teflon tape in the same direction as the thread to prevent unwinding when screwing.

[@GreenShortzDIY]

Hi Joris. Thanks for the tip. I was trying to do that in my head, couldn’t always visualize which way the fitting would turn. Thanks for watching.

[@Mostlyonoff]

The tail should be trailing , not leading

[@dropshot1967]

Pressurizing the tank will also mean that your flow rate for the shower will be higher so your showers will not last as long. Unless of course you only pressurize during heating. I like these videos of developing ideas and tinkering to make them work better. I just subscribed.

[@GreenShortzDIY]

Good feedback, Jelle. I’m having fun with the build and tweak series as well. Thanks for watching

[@kryptoskaos6214]

Thanks. Provoked thoughts of incorporating the heat exchange and storage efficiencies of a recycled propane or nat gas water heater by replacing the burner and controller with a rocket stove. These tanks are insulated and have engineering, routing, and safety problems built-in at the factory. They allow for heat exchange, gravity supply, and in-line additions of secondary/tertiary heat sources with a bit more planning. Looking forward rocket man.

[@watchmkr100]

Would a pair of check valves help direct the water flow and protect the copper coil from boil-off

[@SeanQuinn4]

I really like the direct conduction you have going with the coil in the chamber, I feel like you could further expand on the other viewers suggestion, to not use perlite in that area, by using a metal pipe of some sort to wrap around the outside of your coil. You could then pack the gap here with a conductive cob, possibly with metal shavings or another conductor. You could make this piped in heat exchanger section larger than your coil and reap the benefits of higher thermal efficiency without the cost of more copper piping. You could further aid the exchanger by using another metal pipe as the inner diameter of the exchanger section of the burn chamber (if creating an exchanger larger than one's coil). Not an engineer by any means so call me out of this is totally wrong.

[@GreenShortzDIY]

Good ideas Sean. I’m no engineer either, so you’re in good company. Thanks for watching.

[@irishwest]

Sean, I agree totally with what you have posited, I would also personally want to add something like sheet metal on the inside of the copper coil. Not only to add thermal transfer (if you get side tracked like green shorts did and the fire goes out, you have some heat from the sheet metal to help maintain. Plus if he lost the updraft and cold air came in, wouldn’t that make the copper fragile over time?) but to protect the coil. I would want to encase my copper coils in something equally protective and conductive. If the inside of that copper coil is continually exposed to high heat (the flames are 2 feet above the chimney), the copper will become fragile, leak and break in a short period of time! At work i deal with various types of tubing, including copper. Our copper tubing is run through heavy magnets (biggest ones are 6500lbs) for cooling. We have copper fail on the inside of the magnets because of prolonged heat exposure, we started wrapping them in this non-conductive material to protect them but only after the copper has failed internally to the magnet. Also, I just personally repaired an input copper flag over the last 3 days. We require DI water, but only get Chill water from the hospital. So we deal with the friction of the cold water full of minerals ‘sand papering’ the inside walls, 24-7. The copper literally just crumbles. I understand that I am dealing with some of the extremes of copper, compared to Green Shorts, but science still applies. Protect the inner walls of the copper tubing, ESPECIALLY where there may have been a “little kink in the tubing that was fixed”. That may flow water normally without restrictions, but you have created a stress spot in the tubing and direct heat (ESPECIALLY FIRE!) will be the first place that copper tubing separates. Damn, I was tryin to be short.

[@thebeardedone1225]

you should run it into an old water heater like I did. Keeps it warm for a long time. Hook your w/h drain outlet onto a 12volt rv pump, and from the pump to a shower wand. instant pressurized hot water. you just have to release the pop off valve when draining, to allow air in while draining.

[@davidburks5178]

Would a closed system use thermal syphoning to create pressure? Maybe use a check valve to avoid a backflow? I haven't built one yet, but plan on giving it a try.

[@GreenShortzDIY]

I’m not sure a pressurized system would work, but I’m not a pro here. :-) The PVC I used was not for pressure. I did another take on this and used house water to pressurize it. It did ok. I think they way I’d proceed is to fill the tank, warm it, then re-pressure with the house water only after the fire is out. I don’t want to risk getting scalded. Thank you for watching. Good luck with your build.

[@huntermarino6109]

I think it would be cool if you found a way to insulate the tank so it would hold its heat for a longer period of time, in this situation it might not be necessary but I think it would be something to try. Thanks have a great Saturday!

[@GreenShortzDIY]

Good suggestion Hunter. I plan to use the water immediately in most cases, but insulation would also make the whole thing more efficient. Thanks for watching.

[@NotSoCrazyNinja]

I'm telling you from experience that there is nothing like a HOT shower somewhere that it's really cold. The last time I had anything of the sort was when I opened the bathroom window (a full-sized window) in the middle of winter while taking a shower. The bathroom became a cloud chamber. Probably not great for moisture control, but an outside shower might just do the trick.

[@GreenShortzDIY]

I hear you on that, Mark. I’ll have to give it a try this winter. :-) Thank you for watching.

[@seanelkins4530]

Just an FYI: when solvent welding you really should spread the cement on both pieces before gluing them together.

[@GreenShortzDIY]

Sean, thanks for the tip. My second version of the tank, which is pressurized, leaks pretty badly. But, I'll file this in the archive for my next PVC build. Thanks for watching.

[@wesleyshafer6310]

I think if you put the shower on one side of the tank and put the tank at an angle it will help with pressure expecily when water level is getting low or maybe a 45° in the middle as a v shape

[@GreenShortzDIY]

Thanks for the ideas, Wesley. I like the idea of a V tank. Interesting. Thanks for watching.

[@phillipantunes]

@@GreenShortzDIY you can just put a tire valve in the tank somewhere on top and pump it up with a bike hand pump or a foot pump to add pressure , but the system would have to air tight, so you would need another way to mount the thermostat gauge, like a threaded version of it. Also keep water in the tank during the day and paint everything black, the sun will help heat the water a bit

[@rebelstudio2493]

I think the top hose should be the cold water hose and the bottom one be the hot water. As the water is flowing downward towards the heat and will heat up faster. Most of the heat is at the bottom.

[@baronyoun721]

Instead of using a 45 degree connector off of the tank have you considered a ninety degree connector so you have complete drainage of the pipe with minimal measuring and tweaking?

[@GreenShortzDIY]

Baron, I think that’s a great suggestion. Thanks for sharing. Thanks for watching.

[@BrianKlatt]

Pressure due to gravity is a function of how high the tank is above the showerhead. You can get A LOT more pressure without using pumps or a pressurized tank by simply raising the tank and running a pipe down to the showerhead.

[@GreenShortzDIY]

Good suggestion Brian. Thanks for the tip.

[@bigskydiy877]

in a standard shower, there are two source water lines in order to help control the water temperature. In this scenario, one could easily heat the water to a very dangerous level. Can you add a cold water tank and then a similar valve for a standard shower (or any way to adjust the flow of each temp). Just trying to think of safety and scald prevention. Rocket stoves can produce intense heat and if not closely monitored the tank could easily get close to boiling temps since it has a relatively small capacity.

[@GreenShortzDIY]

Yeah. I was (am) concerned about the water getting too hot. My first test with the bucket did get too hot to dip my hand it. I like the idea of a mixing valve like a regular shower. Thanks for the idea. Thanks for watching.

[@budpratt4295]

How about a system that heats with wood and then runs the hot water inside the house to the indoor water heater. Thereby reducing the energy cost ( I have to use propane) to provide hot water.

[@TheMusiMu]

If you're planning to install the pipes outdoors permanently, you should consider spray painting them black. They then will warm up throughout the day because of the energy of the sunlight, in summer that should be already enough, and you won't even need any further energy to have a warm shower. best wishes from germany ;)

[@GreenShortzDIY]

Ich mag diese Idee. Außerdem denke ich, dass die schwarze Farbe es weniger krass machen würde. Danke fürs Zuschauen, mein Freund.

[@pauljs75]

Definitely going to need the line water supply to produce pressure with the current setup, since a horizontal reservoir tank means there's going to be nada as far as head pressure is concerned. Barely going to trickle. Reservoir also needs to be well above the tap that drains from it unless there's some other source of pressure like a pump. Might not be a bad idea to repurpose one of those 5 gallon beverage cooler barrels as your reservoir, since those should be common enough and they'll be insulated to some amount.

[@GreenShortzDIY]

I agree the pressure line will help. It did actually have a better flow than I thought it would. I like your idea for the reservoir. Thanks for watching.

[@phylismaddox4880]

Standard water heaters are hot water heaters - it's what they do 90% of the time. They heat already hot water! I know that's your prototype but if your going to heat the water then shut down the stove, you'll need to insulate the tank and pipes. You're definitely losing heat without insulation. so it will increase efficiency either way.

[@GreenShortzDIY]

That is an excellent point, Phylis. :-) Thank you for your suggestions as well. I plan to use the water right away, but insulation would be a good addition regardless. Thank you for watching.

[@docink6175]

you most likely have a large air space at the top of your tank, your inlet should be at the top of the tank but you can probably just lift that end until its higher . Maybe check out the car top showers with an inlet at one end and the outlet at the other, many have a Schrader/tire valve. so you can pressurize the tank. If you use black abs or paint the tank black it will be plenty hot with just the Ga sun in warmer weather

[@GreenShortzDIY]

Thanks for the feedback, Doc. I agree with your air gap concern. Ultimately I think I’ll be making the tank vertical. I was thinking about using my air compressor to add pressure to the tank. Thanks for sharing your ideas. Thanks for watching.

Thank you. I may be moving to an off grid homestead and I have not seen a rocket stove built, which was so interesting to me!! I would love to see how to make an outside Cobb oven!! Blessings!!

[@GreenShortzDIY]

Mary, I’ve done a cob bread oven video. Look for the “Full Build” in the title. Also suggest you look into a Rocket Mass Heater to heat your home. It uses rocket stove combined with a barrel to divert the exhaust down and through a mass to absorb and radiate the heat slowly. An 1000 degree stove burn will only exhaust 150-200 degrees out the chimney. A 2-hour burn can heat the house all day. You may be able to route your water heating through the same system.

[@notthereyethomestead8413]

Thank you! I watched the 3rd video, I was thinking of gravity fed water flow from buckets vs. pressurized water. I wonder if the stove can heat water fast enough to keep your storage tubes full, to take a full shower. Thank you for your responses and videos, and I will look for the oven video. The rocket stove is definitely a solid option for heating my future dwelling, since commercial stoves do burn alot of wood, though they are building mostly for pelleted fuel, which I am not interested in!! The prospect of using wood that I harvest, and using much smaller amounts due to these stoves efficiency is exciting to me!! Thank you so very much!! Blessings!!

[@notthereyethomestead8413]

Oh, I just ordered last night the book on building rocket mass stoves, then your video popped up!! My LORD works to keep my life on HIS tracks, waiting for HIS path to become obvious is so hard at times, but this is working better than me charging ahead with my plans and HE can fit in as my aide!! Blessings in abundance!!

[@jdowies]

Maybe if you added 3 undersized baffles (dampners) to the center of the stove chamber it might direct the flame out to the pipe coil. If the flame chamber is 5" in diameter, add three 2 or 3" baffles (like a dampner). The flame would still go up but maybe direct some BTUs to the outside coil. Also, water pressure would increase if the tank was vertical and higher. Or, if the coils were not embedded in the clay, but out in the flame they would absorb more heat. Just a thought.

[@GreenShortzDIY]

Good thoughts, Angel. Thanks for sharing. Thanks for watching.

There is a guy on utube on camper van Kevin site and it is showing us how to make a shower that u only need 1 gallon of water and u can take a shower for a hour with it.

[@Bedsheet_Necktie]

Frankenstein project !🧟‍♂️ Just grab an old cast iron tub, through it on the lawn, fill it with water and light a fire under it. You could be like bugs bunny. jk

[@GreenShortzDIY]

I'd need some carrots to go with that. One to eat and the rest to go in the water with me. :-)

[@roypatterson9910]

You had it right, it is a hot water heater, so who told you differently is wrong. When you get a hot water heater for your home, you wouldn't go to Home Depot, Lowe's or Somerville Plumbing Co. and say you need a water heater, you would ask for a hot water heater or a hot water tank, which is all a technicality, but they are all the same thing, except for a boiler.

[@RogueOntheRoad]

You can get a plastic pipe in the lawn watering section.

[@GreenShortzDIY]

Thanks for the tip. I am rebuilding the tank and found the small section of pipe you recommended right where you said it would be. :-) Thanks for watching.

[@craftymulligar]

Maybe abs pipe is more durable mabe less available with other fittings. Sun would degrade that pvc. And if it drops pvc breaks and cracks easily.

[@andrewsarles3520]

no primer?

[@GreenShortzDIY]

My thought was that a no-pressure system would be ok without primer + glue joints. I do think I’ll bring pressure to this system, so that may come back to bite me. Thanks for the feedback. Thanks for watching.

[@matthewharvey8755]

Primerless glue?

[@GreenShortzDIY]

Yeah. I wasn't as concerned about the joints given that this tank wouldn't be under pressure. But, when I build a pressurized version of this tank, I'll definitely be using primer. Thanks for the feedback.

[@matthewharvey8755]

@@GreenShortzDIY I wasn't sure if there was a new product or not lol. I'm glad it worked out for you, I want to try this with my mini water tower :)

[@ianlevine273]

It would not look as nice but would be easier to build and likely work a little better to get rid of the center tap, install on a slant, and just connect cold return and shower head to the low end and hot return to the high end. Coming out of the low end with a 90, you can still connect the cold return and shower head oriented perpendicular to the ground. Alternately you could orient the tank vertically, would have pressure for the first half of the shower and improve the thermal siphon. It’s getting large enough that if you go for a larger tank, you may want to choose more diameter vs. length.

[@GreenShortzDIY]

Ian, ultimately I agree that the tank will need to go vertical. My choice to go horizontal was more to do with mixing hit and cold water, and easy filling. It also worked with the space I had. But you’ve given me an idea on perhaps converting my big chimney pipe stove into a water heater and use your slant idea. Thanks for the feedback and for watching.

[@smeemcghee]

This will work a lot better with a significant difference in the height of the cold outlet and hot inlet on the tank. Without this there is not enough of the thermosyphon effect. So the tank can only work if it an upright version. This is why it isnt working well - nothing to do with the Rocket Stove setup - which is fine

[@GreenShortzDIY]

Thanks for the feedback, Steve. I thought about a vertical setup as well. I’ll give that a try in my next iteration. Thanks for watching.

[@stuartevans6807]

But the higher the difference the more stratification of the water. If you do go for the pressurised system i would put an elbow on the end which drops down to the feed so the cold water sits lower while having the shower. In current setup cold water will cool the warmed water straight away

[@ignis86]

You say it worked to a degree? From what I saw it was to 100° :D

[@GreenShortzDIY]

Ha! True. Thanks for watching.

[@tjgorla]

when we camp we use an outdoor shower in 20 degree weather. 50 would be great.

[@GreenShortzDIY]

That’s brave. I think I’d skip the shower in the 20s. Ha. But, I see your point, 50 degrees would be plenty warm for a camping shower. Thanks for the feedback. Thanks for watching.

[@col2959]

Bro your clever but that pvc no. Get an old tank ideally an old electric go directly to that as will have pressure gauge. You must have a pressure release. Must . Elevate it or use pump. Possibly 100% free hot water. I been doing it for years. Too easy

[@GreenShortzDIY]

Thanks for the feedback, Col. your metal tank is a good idea. Thanks for sharing. Thanks for watching.

[@col2959]

👍🏻I enjoyed the video

[@DavyDoo69]

Take in account when attaching the garden hose (pressure) it will push the warmed water out quicker, thus requiring larger storage capacity to maintain desired time usage. To calculate storage capacity & time (usage duration) for garden hose pressured, simple time & fill a 5gal. bucket (With shower head & valve)(wide open or set setting). Example = 5gal. took 5min. to fill and you want 10min. shower, which = 10gal. storage capacity required..... Note: If your going to add pressure you will need to change your storage design.... Cold must disperse inside storage container at the bottom while the hot exits at the top.... Food for thought.

[@GreenShortzDIY]

Thanks for sharing your thoughts, Davy. Good insights here. I will definitely take them into consideration as I modify this outdoor shower set up. Thanks for watching.

[@jimsiggy]

Black steel pipe is not water pipe; it'll rust.

[@GreenShortzDIY]

Thanks for the tip, Jim. I’ll likely switch to a PVC segment when I shorten that section. Thanks for watching.

[@bendegroot3429]

you used the shifter upside down

[@danutplesu3352]

Not being a dick here, but this is a normal stove. From my knowledge, rocket stove has an afterburner where gases burn completely so is way more complex. It would be interesting to see it made small scale from cob and brick and it shouldn't take that much more space.

[@GreenShortzDIY]

Ha. True. I do plan to make a full-fledged rocket stove at some point soon. Thanks for watching.

Also, I don't think regular pvc is proper for hot water. You should have used red pex or copper 🌠🌠🌠🌠🌠🌠🌠

[@GreenShortzDIY]

Yeah. This is not a normal use for this type of pipe. It is also not rated for pressure. I think it should function ok for this application. Of course, in this outdoor application, a few drips won’t be the end of the world. :-) Thanks for watching.

[@Khamomil]

I like your green ideas, still you use a lot of plastic in your projects! For my part I would try to avoid buying at big stores and look for materials that can be recycled.

[@GreenShortzDIY]

Thanks for the feedback. I agree on your focus on reusing materials. My take on plastic is that it is a great building material for permanent uses, versus single use or disposable. That said, PVC is a Redlist item for the Living Building certification. I’ll agree that a more natural material is always better, just maybe harder to find. Thanks for watching.

I know of a far better water heater that works on a rocket stove and heats 50 Letres aka 12.5 gallons to 80°C aka 176°F with less than a dozen sticks that are 3/4 inch round and less than a foot long

[@henrykudlacz8888]

Typical American is complicating things which are very simple. Water pump 12 V give you some pressure and heat 10 gal of water the military style is fast and you don't need rocketstove ( insert to water metal pipe like U and heat with large size propane torch) Perfect also for camping. To check temp. of water you don't need scale of F just submerge hand )Your project looks more "scientific".

[@GreenShortzDIY]

Ha. I can appreciate your solution. My angle is usually experimental, which usually starts out complicated and then simplifies. I often start with a rocket stove as a base, creating energy with found fuel. Thanks for watching.
