This is fascinating. Thanks for posting another great video, Dave!

Great video Dave. Love how you explain things so clearly. Thanks for sharing and please do more. Mailbag rocks but so do these :)

I was working out how to make a bullet proof way to seebeck the energy to run the hvac fans in the winter months.... Good to see your little harvester Dave.

The Russians had something like this back in the 20's, but it used zinc-antimony/constantan instead. Most people have a small heat generator right in there house.... A thermocouple. Of course this is different than Peltier and Seebeck device, but it generates electricity. (found in your furnace, water heater, fireplace...etc) They used devices like this (thermocouple devices) to power old vacuum tube radios in remote locations. Lots of thermocouples together, and a kerosene lamp below.

Thank you for giving Seebeck the credit he often doesn't get :)

One question! If its all about heat flow, then nothing is really lost, so if you banked up 2 or more panels, would you get >5% "efficiency" ? I mean it doesnt matter what the temperature difference is, just the number of joules available?

At 22:20, you said that the Charge controller turns on the MOSFET to draw power from the C_store. But I think it's the other way around. The MOSFET is for charging the capacitor and the schottky diode is for when the power is drawn from the capacitor.

Ben's things & thoughts It is indeed! A viewer got it for me.

I was just wondering, could you use a number of these strapped to the casing of an electric motor so you can reclaim some of the wasted heat energy? I was thinking maybe like on a small electric vehicle, say you Sinclair C5. Stick a bunch of these to the motor housing, and use heat pipes to put a big heat sink out the side of the vehicle to keep the other side of the unit cool. You could then put that power back into the batteries. I know electic motors don't waste a lot of energy as heat but they do get rather warm and every little bit helps right? Would this make for a noticable (if very small) increase in range?

You said you are looking at a TEG for some specific application. Is it for the µWatch or something else :)?

I tried to build the LTC3109, but didn't work... I really don't know why. Check the orientation of the transformers, caps values, pcb layout with DRC etc.. got nothing... anyone else tried to build something like this?

It will be relatively quick (vid 1 hour long)

So Dave, final opinion regarding the powerpot and biolite stove...

Wouldn't it generate the same voltage as it's voltage drop and have the current flow vary based on temp? To turn a greyscale LCD segment on you need at least a volt.

I notice the Agilent U1272A hasn't gotten any exposure lately. Is its curvy body too lascivious for the EEVBlog? Or is that 30k count too much to handle?

hi Dave. at 29:00 you wanted the cap to go over the 5.25 volts but you miss a 5.25 volt zener diode inside the LTC3108 next to the rectification.

Hi Dave Have you looked at the Powercast wifi chip for energy harvesting, it looks impressive but could also be a lot of hot air. I remember you did a video on wifi energy sometime ago and the numbers were BS. Just wondering if technology has moved on since then and we can actually get small amounts of power from the wifi back-scatter.

@7:54 I thought if there is a temperature gradient or differential (and thermally conductive) then energy must flow. Is this not so?

OK so how does the LTC3108 oscillator start? You need something with positive dV/dt to trigger the MOSFET the first time. With 20 mV DC in, the circuit as shown will just sit there forever. The LT data sheet is concealing the magical bit.

Will it work if one heatsink is outside and one is inside? BTW i live in north so it's always cold outside:D And the scale should be bigger if possible,like 2 by 1 meter.

How does the resonant oscillator start? Also, at 1:50 you said "they form a chain of PN junctions" . That isn't the case because the P and N types do not touch.

Really enjoyed this video!

Could you give some discussion of the thermal considerations, like how the thermal impedance is influenced by electrical power generated? This would allow us to calculate how long it would take to reach thermal equilibrium given the thermal masses on each side of the generator at different temperatures, power generation, thermal time constants, etc.

Love the video and the introduction to linear's energy harvesters.. You got around 25°C differential. A lot of TEG's have a best output (delta?) at around 75°C differential so should be a lot more potential power to get out of it. Have played some with TEG's and found that you can get a lot more power out of them using watercooling and woodstove (not very scientific but the amount of heat energy going through the element is huge). The problem is of course that the soldering can't handle to much heat and having to keep an eye on the setup defeats the point of the energy harvesters.

Would reduce the thermal transfer, having it baked into the heatsink, however, may be less efficient at recycling but also less inhibitive of the heatsink's thermal wicking.

It's also important to note that Seebeck was FIRST!! He discovered the Seebeck (and many speculate possibly also what we now call the Peltier effect) over 12 years before Peltier started his experiments.

I played with one of the little frig coolers, they suck up electricity and give you little cooling in return.

With all the testing you did, is there a sweet spot in the temperature differential to give the best energy production? I did see a guy set up a large seeback module with a heat sink outside (winter temps) and a wood stove near it. so lets say 5 degrees outside and 32 degree's inside. Would that produce more power than 15 degrees and 25 degrees?

Hey Dave. Do a video on how to design an AC to DC converter for using in energy harvesting technologies.

*opposite is the seebeck effect. If I remember that looked straight out of a forest mimms book.

do you remember the old train mechanically driven by heat differentials? i cant remember who made it (the name of) but maybe you could use it in conjunction with this to generate energy! i googled it now though and remembered its the Stirling motor! so add an alternator small enough to run it smoothly with a stirling motor and test the output on that for the max time you can run it that would be interesting i think :D if i had the money i would get and use 1 so that if it runs smooth enough you simply add another alternator the other side of it and get double the power output! (obviously it would be double minus the friction energy loss of it running two alternators ofcores. im interested in energy generation of bigger scales than say float charging. then add inverters for ac power output using the best smoothing capacitors and batteries :P another good one is hydrogen ofcorse but too far for alot of people and its not surprising really but could be better than nuclear energy in the long run.!

8:05 - I was waiting for the "Doh" moment.

We bought a cooler with a Peltier device that failed early on. I took it apart. I found black sealing compound in between the a Peltier and the heatsink! There also was some heat transfer paste in there but it effectiveness was diminished by the addition of the black sealing compound. Looks to be an assembly error where the a Peltier brushed against the sealer. I called the company and talked to who I believe was an engineer. He really didn't listen to me, but did tell me to send it to him. I got a new a Peltier in a week or two. I had left a heatsink on it and got a heatsink back. However, the one I got back was for the outside, and I had sent them an inside one. I was stuck with two outside heatsinks which the inside air deflector didn't fit and would fall off!

hey some kid in Canada figured out how to make a flashlight out of a Peltier Module, and a "Joule Thief" I think. A flashlight that used no batteries just the heat of your hand to give useful light-- here's the link and HOW COOL IS THAT, Eh?

I bet the "cool" side of this peltier was getting warm, thus the need to apply ever greater amount of energy on the top side to keep the thing generating power, they (Wurth) should have made the peltier in this kit detachable, so you could actually put the cooling radiator in a bucket of ice cold water or even use some dry ice or something to max out the effect I heard of kits sold in Russia years ago, USSR time, where you had a "brick" sized pallet of these, you put the hot side against a wooden stove used to heat up the room in cold weather, and the cool side is in the room ambient, those things supposedly could generate enough power for a small radio receiver in places where there was no mains ac, not sure how much of this is true though

I saw a build once where a guy used a peltier element in a candle holder. The heat sink on the cold side was cooled by a fan that was powered by the TEG. So a closed system with a candle as a heat source. Utterly pointless since it didn't do anything more than power itself but a fun little contraption. As for integreting in PC cooling. The problem is that you get so little energy out from them and that you need to drive them at a high temperature delta. You will basically mess up your cooling system to get a fraction of a watt extra and that cannot be used for anything useful in a computer. They can drive those really low power ARM-cores and other extremely low powered things like the board in the video. But then you need another heat source. It all boils down to the extremely low overall efficiency of a TEG with the voltage regulator. So it cannot really efficiently be used as a energy recovery system in a computer. But there are other neat things like phone chargers than can be used with a camp fire so you can keep using your smartphone while you are out in the wilderness. Another important thing regarding the efficiency. As soon as you start talking about larger scale energy recovery, you will pretty much always be better off with a sterling engine or some other heat engine cycle. Sure, it includes moving parts but you get much better efficiency and that's what it's all about. I've seen a coaster with an integrated tiny sterling engine that used the temperature difference from the hot mug or cold glass to generate some electricity. It claimed to be able to charge a phone but I am sceptical about that. It was also rather expensive but very cool. Mercedes (or was it BMW?) are actually working on a full steam turbine (Brayton cycle) for their cars where they use waste heat from the engine to boil alcohol that powers a small turbine which in turn runs a generator. TEGs are really really cool but the horrible efficiency means that they are only ever useful for some very niche, low power applications.

Thank for demystification

This was excellent,but not what I wanted to hear. I would have liked it better and it would have more directly answered my questions about the Seebec/Peltier value if EEVblog had matched the back side of the plate with sufficient heat dissipation to sustain the heat injection on the top. If I connect 10 of them in series could I get to 12v?

yeah... Seebeck-Effect... the energy-source for Voyager 1 & 2... (Radioisotope Thermoelectric Generator)

nice one got one to experiment with microbial fuel cells meaby you wanna do a energy harvesting with nature video :)

It's a bit like an electronic version of a Sterling Engine.

How relevant would this be to, say, a hobbyist computer builder who likes to push his hardware to its limits? I'm thinking I could stick a Seebeck module on an overclocked CPU and use its heat to generate electricity to be fed ack into the system. Would that cut power usage by any significant amount? Significant, in this case, meaning: could it offset the extra power used by an overclocked device by even a few percent? Or maybe produce enough current to power a fan? I'm thinking I should try this out for myself.

What happens if you stack Seebeck modules on top of each other? If the heat transfers through from one side to the other, would you be able to harvest the heat transfer multiple times before it reaches the "cold sink" on the other end? Would this affect the output per module such that the overall energy output is no greater than with a single module?

@oriole8789

9 жыл бұрын

It can be done both in the peltier case and in the seebeck case, but stacking for both approaches requires different techniques. For peltier mode, each additional module has to not only transfer the heat from the original source, but take up the extra heat generated by the previous device, plus its own internal heat. So efficiency drops off quickly, and you essentially need a purpose-built system where you're very well aware of what your thermal gradient is through the system to get the best end result. Such techniques can be used to achieve cryogenic temperatures but it's neither cheap nor easy because you'll need specialized modules at that point. Same for seebeck mode, where each additional module has to have different chemistry in order to maintain efficiency. This subject is widely discussed in various papers online should you wish to get more detailed info. :)

CalcProgrammer1 Not really, bottom of the first would be identical in temperature to the top of the second (if you place them in series, aka stack them). Of course it works when they're parallel. However, with regular peltiers you can do this. In a lot of high-tier stationary cameras (scientific-CMOS and emCCD for microscopes and space-observation), the sensor itself is kept cold (typically -40 to -100). The temperature differential of a single peltier can't cool that far, so they're stacked to increase the overall maximum temperature differential.

These are the kind of videos I like, not those shit mailbag ones... Thumbs UP!

Nice!

5% teg efficiency could be a deal breaker for my project. on top of it all, so far i an only able to produce a max of 400mw using my eyes and hands on a load tester looking for mppt. my max current i have seen is 300ma using copper water blocks, artic silver thermal compound and 150f on the hot side and 30f on the cold side.

Cool CERN shirt :)

Put the Peltier inside a cap so it thouch'es your forhead. connect it to joule thief, and light a led.

5 multimeters on the same shot? now you are just showing off! lol

It looks to me like the 1:100 turns ratio step up transformer feeds a Voltage doubler in the LTC3108 Energy harvesting chip, not “a single diode rectifier and filter there” as Dave said. With up to a a 5% efficiency the technology is barely usable. My ice less pick nick cooler barely works. It never gets the pick nick food cold, but the food never gets hot or spoils before being eaten while tent camping, it runs down the car battery over night. We camp only where there is electricity.

5 meters, 4 to take measurements and one to emulate a brick :D

shame you can't use the thermal energy off a cpu to cool it without a heat sink or fan :/

Then it will stop working.... there has to be a temperature difference between the two junctions...

you newer get thermal equilibrium, until ambient temperature isn't equal to heat souse temp. energy flow until there is temp difference in system, ambient is part of system!

sadly the efficiency is so bad, about 20% when i remember correctly. I watched some videos and investigated on the thermotunneling principle. it sounds like a valid idea, the problem is, if you ask me, that they are using wrong materials. Carbon nanotubes could stabilize the gap between the metals while maintaining almost perfect heat isolation. i dont have the money to try that, sadly.

All that for 5% efficiency? Is that why the car fridge I bought at dick smith really sucks and can't even cool down one can?

They require a lot of current, while the industry is trending toward energy efficiency. While they can be effective, air cooling is sufficient in most cases. They just "move" heat, not "remove" it, so you still have to have a cooling system able to move their waste heat elsewhere. Proper setup is nowhere near as trivial as a traditional HSF combo. Water cooling gets you geek cred without having to explain what a Peltier is.

+Justin Hall From what I've gathered, 1/3 of the power consumed goes into cooling, the rest is heat. So if you used, say, a 72W peltier element to cool a CPU, you'd have to dissipate 48 Watts worth of heat, while only being able to draw 24 watts worth from the CPU, so you'd probably be better off just trying to dissipate the CPU's heat directly.

Well, that's about how well a refrigerator performs actually. The hot side of the coil almost always releases more heat than the cold side can absorb, but I see what you mean. If you were going to do it, you'd want to put a heat pipe from the cpu to the Peltier element, mounted to the outside of the case with a big heat sink to dissipate the heat, otherwise you'd be shooting yourself in the foot if you released that heat back into the case. Still less efficient than a fan and sink.
