I never considered the solder's composition making such a difference. The way you broke it down made it obvious. Thanks for breaking down the difference between the TECs and TEGs. I always just assumed (and you know what THAT word entails) that it was just marketing to target the same device to different needs. Thanks Rob Cheers :)

You'd be surprised how important that lapping is! Glad to see you mentioned it!

Thank you so much for explaining this to me, these will be used in the future of mechanical engineering. say goodbye to loss of mechanical energy from friction and heat transfer.

There used to be a company in Iceland that made thermoelectric generators specifically designed to be use with geothermal hot water or found out about them after i saw some being used in New Zealand to make power from geothermal steam for a private hunting cabin between Taupo and Rotorua

I have been aware of these for over 40 years but never took time to really learn about them as I have never needed to use either the TEG or TEC thanks for explaining it Robert

I've a simple heat fan that ran 60 dollars on my wood stove. Went down to the Amish stove dealer in Shipshewana & a slightly bigger one was $179. I didn't buy it...Thanks for explaining the difference.

Thanks ! I made my own stove fan a few years ago using two TEC modules and some heatsinks. It didn't last very long, now I know why. Will rebuild it with some TEG's instead. Thanks for your info.

Thank you Sir Robert. ❣
This poses another opportunity for backup, especially under harsh conditions like existed in earlier world conflicts where transportation of bulky fuel engine generation was impossible.

I always wanted to try these. Turns out I ordered the wrong ones. Had I watched this video I would have known the difference. :) Ive always wondered if there was enough potential in my outdoor portion of my stovepipe to make something work. Good info, thankyou.

Not so important in this instance but there is a fail-safe incorporated into most stove top fans.
If you look at the base of the stand it has a grove cut in it and a bi-metallic strip screwed in on end. If the base gets too hot the strip bends and tilts the fan so only one edge is in contact!
The kickback against planned obsolescence is real! ;o)

Great information to know both for the DIY crowd and those of us who buy ready made products. I always look forward to watching your videos simply because I'm an information junkie.

I think it would be interesting if you combined this tech with a solar setup. You explained in an earlier video how solar panels are more efficient at lower temperatures. I wonder if you could use TEGs to simultaneously cool the panels while providing extra power.

thanks for sharing about the Sp1418, I didnt knew about it, just the regular TEGs

I did stumble across a place that had put teg's in graphene, claimed it did a similar thing to your gasket idea at the end, gonna have to try that gasket idea for myself. thanks for the chat good sir.

These are great i have a number of them but i made my own using large diameter copper pipe to make a biplane as the cold side heat sink & copper pipe as the stand it's great & is very different.

Thanks for that, burnt a few out and was hoping for a better explanation. Cheers

Hi, thanks for covering these! I've been thinking about them a lot since I first heard about them a few weeks ago, really hope to see more optimization like we've seen with solar in the last few years, I believe they have considerable potential for low maintenance green power and I want to see about building a few arrays of them for myself when I get to installing solar panels on our homestead; your other video about vertical east-west aligned (bifacial) solar panels was invaluable to me, in fact you are invaluable to the world. Keep being weird!

Years ago, I made a rotisserie for a camp fire with this principle.

We've had great success with the fan varieties which clamp to the stove pipe and help utilize that exiting heat. Now I'm looking forward to it's demise so I can rebuild it with a TEG. :)

Thank you so much for this video!!! It's the topic i mentioned a few weeks ago in a few comments. Its awesome you covered this topic! Thank you so much for improving my knowledge on this topic! Spectacular! ❤
