You could have the fans that protect the unit run on a completely seperate circuit with their own designated generators. That way they'd be on whenever heat was present and protection was needed regardless of load on the other circuit when in use. Takes away all the risk of ever burning out and also would run as a heater whenever there was enough to trigger the fans. I'm not an electrician at all but it's screaming out to me as I watch this. It can protect itself easily without any responsibility on the end user.
I suggest making a hybrid with a small stirling engine also powering the fans so airflow never stops when heated... Or making a convection based airflow by heating a separate metal tube that connects to the unit via non thermal conducting tubes
Ok so I'm interested in buying a few of these for off grid cabin BUT the biggest downside is you must always be there to supervise the unit. You said it can generate electricity 24 hours a day BUT does the conversion kit assure that the system fans will continue to work without overloading the system? What happens if I'm out hiking and my stove starts to cool off a bit. It's not hot enough to generate the power needed in charging devices hooked up and the fans but still warm enough to over heat the unit. I want a full proof system that doesn't need constant monitoring. Why not a stirling hot air motor hooked up to a turbine??? 🤷🏻♂️
buy a battery..? if not, what else would you do while you're out and the heat stops...do that again..you're not actually losing, you're just gaining...most of the time.
I am thinking of building one for our cabin but with liquid cooling. I have a 20 gallon trash can(FDA approved) on a stand behind the heat shield on the wood stove to melt snow in. Once there are few gallons of water in the bottom of the can the generator can be set on the stove. It would be a win win. With both electricity and a lot of water.
USeful device but needs some more refinements in my modest opinion. I appreciate the difficulties of developing such a unit (its not as easy as it seems) but in my opinion it would benefit of having protection circuitry for overload (i.e. the cooling fans are prioritized to a safe level)
Cut down on cost you can protect your fans and short circuit by adding a capacitor Bank to smooth out voltage and load and add a full Bridge rectifier after the capacitor bank and a bypass rectifier for short circuit protection
Current or load control circuit must add to the unit to protect the device from over loading, fan needs to spin always as long as the generator generates power to cool the system down non stop.
Seems like the diversion circuit is so essential to using the generator properly. Why isn't it just built into the unit? Also I can't seem to locate them on your website for purchasing.
+joshsmallwood Initially we placed all the electronics in the generators themselves to prevent them from being overloaded, however they would not work reliably as they were to close the heat source. It was determined the best course of action was to create an external control system. That control system went through many revisions to finally get to the Diversion Battery Charger with Digital Display we have now. The core technology behind it is the same technology we are about the release in our new water cooled system.

Do you have cold air intake piping accessories and stove fresh air supplies? If you do a video of this this setup would be very impressive. Heating incoming fresh air off the TEG then injecting it directly into the stove should be very efficient in the overall heating cycle.
Exactly one of the benefits to help circulate warm air throughout your residence or dwelling rather than going straight up acting like an HVAC, and you could hurt purify your air at the same time while recharging your a renewable energy source😊
Hello friends, greetings of success for you, the extraordinary innovation you find is the ability of the 45 Watt Wood Burning Stove Thermoelectric Generator.
You would think you would design Sims in your diodes in there somehow so that if the voltage drop below a certain point it would disconnect whatever your charging and eliminate the problem it's so the fan would always be running. What's the longest this unit has run for anybody. It's a great idea there's no doubt about it because ideally if you have an automatic temperature regulating system to sing should last forever it is a great idea except this whole concept of not stopping the use of electricity if you're using too much is an Achilles heel who were the kind of money such a unit cost you can't screw around
More surface area on the hot side dosen´t get u anywhere, because a wood fire is way hotter then those TEG´s can handle anyway! The Problem with TEG´s are to get rid of the heat you put in them. To get more power out of TEG´s u have to raise the thermal difference betwen hot and could side. If you opperate on the max range of the hot side, the only way to get more power out is to cool the could side further down. Thats the reason why he mentions so often you should not let the fans die, because that means a downward spiral effect. less heat removed = less power generated = less power for the fans = system heats up = TEG´s get damaged!
Why not have a dedicated TEG for cooling and the rest for powering other devices. That way you wouldn't have to worry about the unit burning itself out..
Would also be neat if it had its own small backup with alarm to let you know; maybe add a blnking LED... Would power the fans and give you time to address the situation.
It would be possible to make a circuit that can reserve a certain amount of power for the fans and only delivering excess power to the outputs, but this kind of circuit likely wouldn't survive if it was built in as part of the unit. It would need to be attached by cable like the "accessory" he sells which pretty much does what ur saying. This "accessory" should be included with the device by default, but if it isn't and it's sold as optional, then they are selling a very unsafe product.
Could you use two automotive oil coolers or radiators and a small low voltage electric pump and create a closed loop between outside freezing temps to the cool side of the Peltier.. Circulate oil or antifreeze to give a much lower leeching temp to the Peltier. This way pulling more heat away then just ambient room tempter cooling.
any plans for a side mounted unit? it would be a very practical addition to any hot tent camping kit as it takes up no cooking area on the wood stove top.
I'm not a trained engineer. Not even a maker. More of a tinkerer or, to be honest, a world-class dismantler with some deficiencies in my re-mantling skills. Nonetheless the numerous comments about the problems with this device have documented my concerns and therefore I need not re-state them.
Very little engineering would have allowed the unit to have shut the load off automatically when the fan voltage dropped below a certain threshold. What is the matter with yourself?
Im also shocked that it's not implemented. A simple switching regulator on the output (maybe even with a current limiter) along a smal circuit to monotor/control the fans, should not be much trouble.
Lol! I was thinking a similar thing but instead have it built with with the addition of a much smaller teg (prbly 2x series tho) with dedicated fan-powering duty on a separate circuit which = slightly bigger footprint but also = inherently both simpler & more robust design than additional discrete components
Can you create a thermoelectric trickle charger that might fasten around the stove pipe? Or magnetically attach to the side of the stove? I’m mainly interested in electrical charging, not so much in moving air around.
Is it possible to design it so that a fan is not required. Will a passive sealed capillary heat pipe (on the hot that needs to be cooled) extending outward from the stove a bit and with a finned surface bonded to it (in the free air) work effectively enough to "move" the heat to the room air without any fan?
The power output is really for emergency use only. At 45W running 24/7 you get around 1kWh of energy in a day and it probably won't work all day every day. Better buy a solar panel (or two), one cheap 12V MPPT and four 300Ah LFP cells. You get 3.8kWh of storage and some useful power, depending on the inverter.
neat product looked at your site can you tell me what would warrant a 500$ price tag for 45 watts as opposed to just bringing a 3 lb 100 watt solar panel that costs 1$ a watt why would I buy your product and what makes it special
It can generate power 24 hours a day during heating season. So if you generate an average of 40 watts an hour 24 hours a day it would generate 960 Watt hours. With an average of 3 full hours of sun a day in Vermont winters, that would be like having the equivalent of a 300 Watt solar panel. A solar panel that also increases the performance of your wood stove by moving heat around with it 120 CFM fan system.
Argos...Do you understand the concept of "off" grid? As in, you don't have the option of getting electricity FROM the grid? Thus the need to generate your own power? Did you get past third grade?
Generating 45W with this thing would be a near impossibility given how hot the stove needs to be for the thing to work. Person would have to be attending the fire constantly to keep the thing hot enough to make full output.
Hi there, what kind of setup with your wood stove that the chimney tied into and does that exhaust to the outside. This is the first time I have seen this setup and curious if you could share with. Many thanks. r/Hank
Hi Ted Pro. Will your 45 watt generator power a woodstove blower ? I have two 30 watt fans on my blaze king Sirocco 2.01 woodstove. Could I run these fans on 2 of your 45 watt generators ? Thanks. 😊 Is it a pass thru generator ? Or can I run the fans while the woodstove is charging the generators ?
This seems to be developed by industrial controls people. That is not a compliment. I've worked in IT as a Network Operations Manager for years, and some of the worst stuff I've had to deal with has been industrial controls (HVAC controls, door controllers, etc). My theory is that they try to piece together "units" of different types that kindof do part of a thing they are trying to do and get it to mostly work and sell it. I'm basing the comparison on the fact that overloading the output can shut the fans down and "damage the unit." The protections for that would have been cheap, simple, and would use no power to speak of during normal operations. So, TEGpro has designed something that will probably do mostly ok as long as you treat it with kit-gloves. A good design to do this with protections would have been very easy and cost wouldn't be an issue. Edit: Wow. Now I see. They saw the problem and instead of handling it, they point to you a product that handles it. Problem says you? Sales opportunity says I.
This thing as is, looks like an insurance nightmare. I have some suggestions though if you would like to hear them. Expecting the customer to make sure the fans keep spinning after they plug something in, is really risky and arguably an unrealistic expectation. Some things might start off not causing the fans to stop spinning, but after some time they might draw just slightly more and the fans could stop after u walk away. If you sell something separate as a safety mechanism for this concern, I'd consider selling it as part of the unit as is, because as is, this unit without a safety circuit or alarm on it to alert the user to a problem such as the fans dying for whatever reason, those fans could heat up to a point they catch fire. Pretty big insurance risk. All you need though is some kind of alarm circuit at least. Perhaps you could put a thermal switch that triggers an alarm if temps go above safe limits where the fans are. OR you could put a switch circuit attached near the fans that can detect if one of the fans are failing. One last thing... If ur using some kind of circuit to monitor if the fans are working, I'd make sure that isn't relying on weather or not there is a draw from the power source to the fan. A fan that has failed due to fault, or a fan that has failed due to too much heat could still be drawing power while not spinning/spinning properly. This generator is a really awesome idea, but it really really needs a solid safety mechanism that is attached by default. Preferably multiple safety mechanisms such as having both: 1. A thermal detection alarm that sets off an alarm when safe temps at the TEC's are exceeded. 2. Another alarm switch that can detect if the fans are actually spinning, rather than just detect the draw of power to the fan because as described above, there are some circumstances in which a fan may not spin properly but still be drawing power. I would imagine this would be difficult to grt past insurance brokers at a good price. But if you really go ham on those safety measures, I'd bet you could get shose quotes down.
My thoughts exactly.... 1 bought a cubic mini cub for a super rare fiberglass rv. Using it for hot water (thermosiphon on jerry can) Its a very small wood stove close to a wall (venting heat sinks outside) Im looking to build or buy big enough to charge a 2 deepcycle battery bank. Have you had any sucess
EXCELLENT!!! CAN'T WAIT TO REVIEW YOUR WEBSITE! SUGGESTION: * The only thing I can see that could be a problem is that the electrical cord is to close to the stove and could melt. * Yes, you could move your unit to the side of the stove top but, as we all know, that area receives less heat from inside the stove and I'm assuming that your unit would produce less power... maybe I'm wrong. * If you designed your unit to have some type of "extension" or "overhang" that takes the electrical cord away from all the heat on top of the stove, then you would reduce the likelihood of melting any of the cables. Just some feedback. Thanks Retired, Veteran
Could the 45w version be used to charge a 110ah leisure battery ? Obviously not in one night but say during the week ? so I could then run say a laptop for a couple of a hours a week from the battery .
The single input Diversion Charge controller is available at Tegmart www.tegmart.com/thermoelectric-generator-accessories/battery-charger-with-digital-display The multi-input charge controller is also available: This system includes power prioritization for the water cooling pumps as well. www.tegmart.com/thermoelectric-generator-accessories/teg-power-thermoelectric-generator-charge-control-system Note that input 3 is for the new accessory solar panel we will be offering soon.
I’ve been thinking about using one of these to capture lost heat energy from car engines and In turn generate hydrogen. Would this be possible or would it get too dicey?
I like it, but the watts seem low. 45 watts will keep a 40 watt light bulb going and that's it. How about maybe using it as a charger to recharge batteries to run things at night time. Other than that I just don't see an advantage to it. Cost?
Parents got pellet stove for a small house, takes 1000w generator to run it when power is out..(fan, ignition, hopper thermostat circuit) this would have absolutely no hope of keeping up. I'm not even sure it would be worth it, as a supplemental charger for my solar/wind battery banks. 1 solar penal on a cloudy winter day can give 45w, and I don't have to babysit a solar panel.
I'm curious too about the unusual second stove pipe inside. If it was outside I wouldn't be curious, but I did not hear the disquished Wabash cannonball draft while his stove in operation.
@@Reculse If I am going to do anything Im going to use nickel foam metal and iron foam to build Nickle Iron batteries. Lead acid is to heavy and slumped power output, Lithium chemistry batteries are to much of a liability.
I'm confused. Why would anyone use a wood stove to produce 45 watts of electricity? How much wood do you need to generate one kw? I know you said you're and engineering student. When the first "thermoelectric" technology came out I became interested in it, 20 tears ago. The best applications (so far) are the "pellet stoves". The heat by-product generates electricity to drive the pellet stove fan. Great for cabins off grid. I think your experiment is a good one but not yet practical as source of electricity. As the technology gets better, I believe "thermoelectric" technology will be a valuable source of electricity for folks off the grid. I also believe that 30 years from now we will have houses 100% making their own electricity from solar, wind and thermoelectric. Once the technology gets maturing even small units capturing heat from air conditioning and refrigeration can capture waste heat and turn it into electricity to increase the efficiency.
if its not water cooled its just a toy, made to look like something that its not. Like reliable, dependable, durable. order your own teg tiles, water cooled heat exchanger. and build your own for a lot less than this toy would cost. just remember you only have so much power to work with, and if your appliance draws to much than your cool new system won't satisfy your needs

Are they serious? Over $500 for 45W?? A cheap Chinese 1KW Generator that costs $100 and $400 worth of fuel would generate way more power than this thing ever would over it's lifetime and a lot more useful power as well. This thing seems temperamental, fragile and will in no way justify it's purchase price.

This fire pit is one of a few covered pits that is on the list ruclips.net/user/postUgkxAU9pOCSV9Y5JprooHvfxTpOrt4hx8uRM of approved products for Disney Fort Wilderness. The product served its purpose well and provided excellent fires throughout the evening. We were able to open the door and do s'mores, but I had to be careful because the handle was a bit hot on occasions. Additionally, I wish they had replaced some of the standard nuts with lock nuts in some places. We lost the door handle after just a couple of days of usage. Not a deal breaker, just a recommendation. I still give it 5 stars.
Thank you for having an actual engineer demonstrate and present this product!

2. Another alarm switch that can detect if the fans are actually spinning, rather than just detect the draw of power to the fan because as described above, there are some circumstances in which a fan may not spin properly but still be drawing power.
I would imagine this would be difficult to grt past insurance brokers at a good price. But if you really go ham on those safety measures, I'd bet you could get shose quotes down.
There seems to be enough space for at least 2 more units. So that means 135W of power...it should be enough to charge a deep cycle car-battery.
My thoughts exactly.... 1 bought a cubic mini cub for a super rare fiberglass rv. Using it for hot water (thermosiphon on jerry can)
Its a very small wood stove close to a wall (venting heat sinks outside)
Im looking to build or buy big enough to charge a 2 deepcycle battery bank.
Have you had any sucess
what is the make and model of the wood stove you have?
Hmmm with a Overload Protection System and wrapped around the Pipe or Rear-End of a "GStove" would be interesting
great video
Thermoelectric a/c is interesting to!!
Seems like it should include a internal switch to disconnect the external load if the fan stops
EXCELLENT!!! CAN'T WAIT TO REVIEW YOUR WEBSITE!
SUGGESTION:
* The only thing I can see that could be a problem is that the electrical cord is to close to the stove and could melt.
* Yes, you could move your unit to the side of the stove top but, as we all know, that area receives less heat from inside the stove and I'm assuming that your unit would produce less power... maybe I'm wrong.
* If you designed your unit to have some type of "extension" or "overhang" that takes the electrical cord away from all the heat on top of the stove, then you would reduce the likelihood of melting any of the cables.
Just some feedback.
Thanks

Appearantly, the cable is made out of heat-resistant materials...
how many degree Celsius is needed to power the device ? let's say put it out the window at 30-35 degrees Celcius , is it enough?
Anything for a campfire?
Do you guys still make these?
We bought one, it has been sitting on our hot stove all evening, and the fan is not spinning at all. Any advice?
Can I buy one ready to go with usb connectors? $?
What is the biggest generator you sell?
Can more then one be used and connected in parallel?
You should make one that use the incoming fresh air going to feed the fire to cool the module instead or in tandem with the fan
A duct to pull air from a cooler part of the room would make sense
Fixing hot plate at 50 degrees and the heat sink, which thermoelectric module would produce more power: TEC1-12702, TEC1-12706 or TEC1-12710?
How much do they cost in living with no power in Algonquin park for 16 years
Could the 45w version be used to charge a 110ah leisure battery ? Obviously not in one night but say during the week ? so I could then run say a laptop for a couple of a hours a week from the battery .

Note that input 3 is for the new accessory solar panel we will be offering soon.
What is he running the stove pipe through on the left?
I saw that. Looks like there's another wood stove off to the left.
very cool could you scale this up to use a 180c heat source and gen KW power??
U have to have about 200°C different between hot and cold side to get some usefull voltage and amperage, u wont do 1kW
Have you created a new version that cuts power output if rpm’s drop?
Do you a thermocouple array to convert the Sun's heat to electricity? Why burn wood?
that is useful for tiny applications but it would be nice to have one that generates 1000W or more.
You should have power monitoring to ensure the fans are always powered. Seems like a pretty basic design flaw.
What temperature is required for the unit to produce the 45 watts
Does the Thermoelectric generator produce AC or DC voltage??
DC Voltage.

How much this system can charge phone ? Please let me lnow dir thznks
I’ve been thinking about using one of these to capture lost heat energy from car engines and In turn generate hydrogen. Would this be possible or would it get too dicey?
Would it? It would, but u wont make any hydrogen out of it
how hard is it to design a switch that will kill the load when the fans stop turning.....
Do you guys have one with the diversion charger built in to the generator?
How hard can it be to add an overtemperature safety switch...
The energy comes from the fans spinning, a kids toy lol!
no.
it comes from the seebeck effect.
not at all kids toy...
I like it, but the watts seem low. 45 watts will keep a 40 watt light bulb going and that's it.
How about maybe using it as a charger to recharge batteries to run things at night time. Other than that I just don't see an advantage to it.
Cost?
Led lights are very low load, could easily charge batteries so long as it's over 12v. 14.4 would be ideal.
@@MHLivestreams I guess it would be a separate line for a separate set of lights
I'm looking at this in order to maybe use it with a pellet stove that needs electricity to run the hopper.
Parents got pellet stove for a small house, takes 1000w generator to run it when power is out..(fan, ignition, hopper thermostat circuit) this would have absolutely no hope of keeping up. I'm not even sure it would be worth it, as a supplemental charger for my solar/wind battery banks. 1 solar penal on a cloudy winter day can give 45w, and I don't have to babysit a solar panel.
I would like to hear an explanation of that wood stove set up
Please email us with your questions!
I'm curious too about the unusual second stove pipe inside. If it was outside I wouldn't be curious, but I did not hear the disquished Wabash cannonball draft while his stove in operation.
how to order if youre overseas??
can you run multiple of these units in series/parallel to charge a 400W charger for a electric motorcycle?
Well this wont work well charging any lead acid batteries.Li-ion no problem but lead ones not a chance
@@Reculse If I am going to do anything Im going to use nickel foam metal and iron foam to build Nickle Iron batteries. Lead acid is to heavy and slumped power output, Lithium chemistry batteries are to much of a liability.
I'm confused. Why would anyone use a wood stove to produce 45 watts of electricity? How much wood do you need to generate one kw?
I know you said you're and engineering student. When the first "thermoelectric" technology came out I became interested in it, 20 tears ago.
The best applications (so far) are the "pellet stoves". The heat by-product generates electricity to drive the pellet stove fan. Great for cabins off grid.
I think your experiment is a good one but not yet practical as source of electricity. As the technology gets better, I believe "thermoelectric" technology will be a valuable source of electricity for folks off the grid.
I also believe that 30 years from now we will have houses 100% making their own electricity from solar, wind and thermoelectric.
Once the technology gets maturing even small units capturing heat from air conditioning and refrigeration can capture waste heat and turn it into electricity to increase the efficiency.
The energy that thing produces is equal to a halfway decent fart
if its not water cooled its just a toy, made to look like something that its not. Like reliable,
dependable, durable. order your own teg tiles, water cooled heat exchanger. and build your own for a lot less than this toy would cost. just remember you only have so much power to work with, and if your appliance draws to much than your cool new system won't satisfy your needs
Peltier is inefficient. Nitinal or stirling is better at making electricity
The age of effects is gone. Quantum mechanics must replace the piles of Newton apples.

How do these do with charging Solar battery banks? thanks in advance from Chile. Jim
If you use the Diversion Battery Charger with Digital Display:
www.tegmart.com/thermoelectric-generator-accessories/battery-charger-with-digital-display
You can connect directly to move 12 VDC LEAD ACID battery banks with or without a seperate charge controller on them.
Wow thanks for this.
Just asking, are you selling these in Chile yet?
Jim
They can be shipped to Chile now. We ship worldwide to any country that is not banned from trade by the USA.
I guess what I should have asked is: Do you have a distributor here? Maybe you need one.... like me?
2/3 of this country uses wood stoves for their primary heat and water heating as well. Wood is cheap here in Chile.
Also much of the country is OFF GRID.
You would have an open market for your product with out ANY competition, and with a high demand.

I am a north american living permanently here in Chile with my family. I speak Spanish and already have an importation business here.

So this generator has to be monitored 24/7 so the fans do not stop turning. Good prototype but still needs a lot of work to make it viable.
Are they serious? Over $500 for 45W??
A cheap Chinese 1KW Generator that costs $100 and $400 worth of fuel would generate way more power than this thing ever would over it's lifetime and a lot more useful power as well. This thing seems temperamental, fragile and will in no way justify it's purchase price.
"As you can see, the phone is charging"
I can honestly say that I could not see the charging symbol on the phone at this distance.
On the other hand, I have only 10% eye soght.
Why dont you engineer some fans that dont stop spinning when theres a big load?
Why am I only discovering this now?!
does anyone know if this company is still in business? I've tried emailing and get no response.
Same here. They don't write back.
This fire pit is one of a few covered pits that is on the list ruclips.net/user/postUgkxAU9pOCSV9Y5JprooHvfxTpOrt4hx8uRM of approved products for Disney Fort Wilderness. The product served its purpose well and provided excellent fires throughout the evening. We were able to open the door and do s'mores, but I had to be careful because the handle was a bit hot on occasions. Additionally, I wish they had replaced some of the standard nuts with lock nuts in some places. We lost the door handle after just a couple of days of usage. Not a deal breaker, just a recommendation. I still give it 5 stars.
This is a great idea but five hundred dollars is a bit steep for the item.
Wut du des cost?
Oh wow it has fan
