The Story of Silicon Germanium: Powering Humanity's Farthest Journey

The story and science of a very unique material at the heart of some many deep space probes, including Voyager. What is the thermoelectric effect and why is it used in this application? Why is silicon germanium such a good thermoelectric material?

This series is insanely good. Deserves millions of views.

Why are you dead?
You were such a great and interestiting channel, but it's being 4 months since this...

[@thematsciguy6254]

Sorry for the lack of recent uploads. This channel is entirely a one-man operation and unfortunately over the last few months I have been too busy to work on new content. It's not completely dead though! If all goes well there will be a new video sometime next month :)

[@rogerwood2864]

@@thematsciguy6254 Come back, your videos are great. Just stick with it and you'll get your following.

[@DanSpotYT]

@@rogerwood2864 Yeah, was hoping he'd post some new stuff as well! Cheers!

[@MrMishra814]

Thank you for demystifying the Peletier effect for me

[@kristo5521]

I would definitely watch a video done by you about tungsten carbide - cobalt (WC-Co). One of the most strategic and wear resistant materials today which is in part of almost anything that is made to today, at least at some point in the process (tooling, mining). A material almost 100 years old which still hasn't been replaced, but might be in the near future with the attention it is getting.

Great!

[@spacedee6968]

Wow, best explanation there is. Thank you so much for creating this!

[@trumanhw]

I'd've adored a link to Cosmos (A Personal Voyage of course!) Episode 11: The Persistence of Memory
(perhaps the best episode of the series!) ... as your explanation of the golden phonograph:
_"Whooop, augh!, augh!, augh!,_ ... One additional _augh_ per month." ...

[@tobuslieven]

This is great info. Really appreciate these videos. Love the explanation of electron diffusion and the Seebeck effect.

[@joachimsingh2929]

Finally something to power my Mother in laws "back massager"

[@DBuilder1977]

Best explanation ever. So many thanks man!

[@trumanhw]

New sub. FWIW, is there any chance your @2:35 graphic showing a 35% efficiency in Nuclear (steam turbine) should consider the CO2 version which apparently approaches 65% ..? Great channel btw. I found you looking for _your kinda info_ re: inconel and found 'super metals._ Thanks again for the edu.

[@planckqi4392]

Hi, would you continue to make videos like what you've done? I really like your videos.

[@sanjitmetallurgy1205]

please make more

IN914 diode (Silicone Germanium) ..I used to connect an earphone to the cathode end and ground the anode..and without a battery I heard the radio..or some order of connection ...but absolutely no battery

[@greegearl1542]

Are you the same person as the Technology connections guy? Is this Alec? If not, you two sound very similar.

[@thematsciguy6254]

I'm not the same person, but I actually really like that channel! Maybe I have picked up a few of his mannerisms.

[@Sakiayuo]

WHERE THE NEW VIDS AT

[@rogerwood2864]

Come back!

[@brendanseabrook]

Are the sub labels at 4:35 correct as they are both "(majority holes)"?

[@MrMishra814]

N types should be majority electrons or minority holes

[@thematsciguy6254]

Sorry for the mistake! n-type should be 'majority electrons'. I added a card mentioning that.
