1738 The Safety Heater 

Floral foam comes in two main varieties - Oasis - which holds fluid as shown and Sahara which does not. Be sure to get the right one. Never thought I'd be sharing information I learned in my first job 30+ years ago.

This man single handedly saving people from the cold. Thank you.

Well done sir. Ingenuity at its finest.

So clever Rob. To coin a phrase - awesome!

Brilliant! I always enjoy your videos. I look forward to implementing your gift of this design into my own burners going forth. Cheers!

It just keeps getting better all the time! You amaze me! Thank you!

The mark of a Master, he just made something so simple yet so efficient and instead of trying to market it he just wanted to share the absolute joy he is feeling about how and why it works, so we can feel the same.

I am off to the Philippines in about two weeks and at the moment I and at the moment I live in a 6 foot by 6 foot cabin God knows how you guys are all not going to freeze to death this winter.

True engineering, find a problem, create a solution, and what a genius solution it is, thus will definitely be keeping many RU-vidrs from worrying about some of the dangers 👍

Robert I'm so inspired by your demonstrations. I had a wood stove for years. If I only knew what I know now. I would have kept it. Love your videos.

I swear you read my mind...i was litteraly just thinking over the last week was I really wish I could find a safer way to hav my extra/emergancy heat this winter...and you nailed it wow I will let you know how mine works...niw back to your show...thanks again. You really help even in just lifting spirits let alone the practical side

A handle would be great to separate them and can we get one to run on a solid oil like Crisco or paraffin

It is ideas like these that help me rest at night. Thank you so much

No Day is a Day without your pod Super safe and efficient

I replicate your heater and make a drop test. It works like advertised 😃 good job

Oh Rob! You done it. This is a safe it can be you can take a tin-can put it in a pot on the stove! And every man and women can cook heat on the stove! then the planed electric stop come in winter! we don't need to freeze! Thanks Rob! I Just love it! 🥸/Mikael

Ah! I recognize a Davys Lamp when I see one! Dad was a coal miner. This made me smile.

great application Rob!

Amazing.Thank You.

I pray that everyone in Scotland Ireland Wales and England, Europe as well stay warm this winter.

internet vermin are harder than you think to get rid of !

Humphrey Davy safety screen is a technology used to make all electrical equipment explosion proof. Originally used in mines for lamps; going back to an 1815 invention. It really is unbelievable how well it works - excellent demonstration - Rob!

There is much to learn from your videos. Perhaps one day some kind soul will donate a "BBQ lighter with a flex line" to the cause, while you still have both hands in tact. Thanks for sharing. Greetings from Ontario, Canada.

That's totally cool Rob. Soup and tuna cans would be an excellent use for these burners.

Excellent. I now know how to make an economy safety heater and the principles behind the Davey Lamp which I often wondered about. I like a man who enjoys his work.

Very small chickens😁 A great contribution for not burning down your dwelling. This mesh is proving very handy. If my mesh were of a finer grade would that mean I was holier than thou🤔🥰

That is rather cool. I guess that would mean that you don’t need a snuffer anymore

"I use it because I have it" I cant argue with that.

The appliance....of Science. Well done mate, that is such a simple but brilliant concept, I can see so many safety applications for us pyrotechnic experimenters :)

really nice! would small slits angled in get the vortex act? a mesh cup chimney would obviously do wonders. tuna cans have a stamped lip for stacking, if the mesh is close enough for exploiting that stamped lip.

Outstanding 👍😃👍

My son bought a fire blanket once when he was working on his car which now lives under my sink. Am I the only one who now also wants their own work shop? Love these videos they are fascinating! I hope I never need to use any of the knowledge I've learned but if the grid does go down thank you in advance for being so generous with your time and wisdom! If you ever feel the need to write a book I would like to be one of the first on your list to buy it because the frightening thing is we have a generation that are going to be a bit lost without Google and the knowledge your sharing is priceless. Much respect!

This is called executing a brilliant idea.

I love this man spirit I enjoy he’s tutorials so much

A video about the longest lasting wicks would be good

I like the built in safety feature of this one Rob. Fool proof!

Clever. Sure, any open flame is some risk but that negates the serious risk of a burner tipping over, remaining lit and spreading the whole tank of fuel.

Brilliant!

You are amazing thank you

Love your channel sir. I have found most people with your level of intelligence have a difficult time explaining things in a way that non academic types can understand. You on the other hand, make the topics both understandable and entertaining.

Too large to replace a Trangia burner at camp but it does solve a major problem with liquid-fueled stoves. TIP-OVER. I am not sure yet exactly what I will do with this unit. However, watching this video only one time compels me to build one. Thank you for posting this and I now need to whack that subscribe button.

This guys RU-vid channel should be seen by every citicen of Ukraine. They have dire need for some alternative heating at the moment. I like 1700 or 1702 the heater with carbon felt and vegetable oil. This one here is better for the really flammable stuff like alcohol or petrol. I think I will try it with some denatured alcohol, foam from christmas arrangement and cooper mesh. I think I will also try one really small 3-4 cm with carbon felt instead of foam and I hope that it´s not to hot and melt the cooper mesh.

Outstanding & Brilliant very nice finding indeed👋👋👋👍

Bravo Dear Man!!!

Wow! That's a home run in all aspects. My mind is thinking if you can get solar and a Stirling on a full burning stove you can replace an internal combustion in efficiency and it would drop the weight of a vehicle. There is fancy engineering with glass which would allow light to pass to solar. I am itching to try it but have a lot going on in my life. So if you want to look at that go for it.

Great video! I'm glad I found this channel

This is a really interesting design - I love it because it's so simple yet so effective. Do you know what sorts of CO levels does this give out?

Bravo, sir...

You've redeemed yourself for that ceiling torch.

Astonishing 👍

Thank you Mr Chuckle ;)

You are AMAZING!

That is awesom. It makes me think of all the people over the world who've accidentally gotten burned by cook fires and forest fires started when something went out of hand Hope this gets out as an idea to folks.

Cool design.

Speaking of safety do you take carbon monoxide readings of your different heater designs?

Welding Tip - when doing spot welds with a new rod hold the actual rod like a pencil near the work piece. Helps aim and control. Note - my welding is no better than yours but that tip made a real difference to me. Love the vids btw.

That's pretty clever. Nice work Robert.

Very nice. Bet that a tiny piece of carbon foam would eliminate the starting fuel/tissue.

That's really cool Robert, thanks.

Good stuff 👍🏾

Pretty cool. What's that Oasis stuff made of? Looks like green polystyrene...

I added a "catalytic copper wick ", I found by putting an upright tube of copper mesh on the safety screen (scaled like a Bday cake) after it heated up it attracted the flame and changed the shape and colour of it to like a really really deep gloomy orange lantern light plus when the flame is blown out the copper/ethanol catalytic reaction kept it glowing and put it into a standby/economy heat mode . So for times say when your solo camping in the cold or in a car for the winter, yep, no flame.....

Ingenious!

WOW. To heat a small space in an emergency. I still have bioethanol in the shed. Thank you for this useful idea.

Is there a easy cheap catalyst you can dope that mesh with to make it flameless like those Coleman catalytic heaters?

Any concern about fumes related to the oasis foam? Google says it's made of "formaldehyde polymers".

Hi there (Great Job👍) How long dose 100ml last in the heater 🤔 Thanks

Could you get one going with an enclosed wire mantle? That way you have even less loose flame

put a mantel on it and see if it burns better and still safe

Very cool idea. Well done.

Love the ingenuity! Sadly this won't work for me, the temptation to stick my fingers into the easily crushable Oasis stuff is far too strong and there would be nothing left but green powder and a very satisfied me. hahaha

How long does it lasts? That foam material doesn't get consumed? Can it be extended to run 8-10 hours?

This guy is awesome

Nice one Rob

awesome video, you're really going to help a lot of people doing this.

The penny can stove is a blue flame cooking device made from a pop can, I have made some in different sizes, they can boil a 1/2 pint of water in a few minutes with no nast fumes. Again alcohol is the fuel.

That's brilliant

Do you have to worry about co2 levels if you are burning it indoors? Once you have depleted the alchahol will you have to replace the foam or is it reusable? Could you use carbon felt as a Wick?

Now that’s the kind of safety feature I was talking about in a previous burner, could this be used with a mantle? I recon it could I’m going to give it a try! Wonderful Robert thanks.

That's an awesome flame 👏

I wonder if a greenhouse heater could be modified to burn fuels more friendly than paraffin and would mesh help radiate heat?

That would make one heck of a camping stove also. Practically no oppsing a forest fire with that 😆

PLEASE do NOT weld galvanized steel. A lot of strapping is galvanized. Welding the coating vaporizes the zinc and the fumes are toxic. There are special procedures to use if you must weld without removing the coating with a wire wheel or grinder.

I've been thinking about the foamy stuff inside of a sunflower stalk as an alternative wicking material. It does a pretty good job for the plant. Won't know till next year though. I have to plant some and let the squirles get to the seeds first :) Not sure if it only works if it's not broken down or if it's powdered will it still have enough wicking power to do a job. Science awaits.... Tinkering anyway. As a side note, you can also eat the powder and use it as flour. I haven't tried that yet either.

Would this be safe to use for heat in a house during a power outage?

What is the metal band that is used to hold the mesh down on the sugar jar section?

Yeah that's a beauty.

Love it..

Just like the, mesh on a bunsen burner stand. Flame above gas below.

For people who don't have a grinder, a pair of Aerocutters will do the job

Can you give a link to buy the methanol? 1 to 5 gal?

Great video and idea!! Well done! Just a thought would this be safe INDOORS!? (Given its burning alcohol that's ALREADY vapourised I can't imagine this giving off much in the way of Carbon monoxide if anything at all? Given its a clean fuel anyway and it's vapourising before ignition as far as we know!? - Or am I mistaken?) A Carbon monoxide detector reading might be useful to see what levels there are if is safe for indoor use in emergency power outage?? Keep up the fantastic work! Cheers from London 👍😎🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧

Really enjoy Roberts content - I'm always slightly worried that people actually try these contraptions out and burn their houses down (or shed). Reminds me of Johnny Ball from back in the day.

Surly it wouldn’t be that difficult to add a external lever so that the two meshes can be separated on pushing the lever without having to dismantle the burner and cover ?

Sooo cool 🤩

Man you build something everyday

So you could probably modify the wicking arrangement with the carbon felt and a larger reservoir? How might one control the heat out put? Instead of moving the wick up and down, might it be more convenient to move a mantle? Perhaps a telescopic or sliding mantle.

And if we put a flower clay pot will it radiate heat............

👩‍🔬Nice safety feature Mr Smith! Reminds me of how TheVaporKid would use metal window screen and/or steel wool as a backfire 🔥arrestor👮‍♀🚓

I wonder if when the Oasis foam gets low on fuel in it will it then start to melt or burn itself? A candle wick without wax will burn up. One thing I have been thinking about doing is to source some of the Oasis and use it to cool carbon arc rods(tightly bound side by side) by filling it with distilled water. Evaporative cooling. Then lay on top of them battery carbon rod centers. Heat the top side, the Oasis cools the bottom side and see if that will produce current. I figure if the top layer of rods has a different impedance than the bottom rods then it may make a thermopile much like your paper and pencil one only larger. I don't know, but may be worth a try to find out as it would not be quite as fragile.
