- The internet feels like an absolutely essential part of my life. But only a little over half of the world currently has reliable access to the internet and all of its benefits. So today, in collaboration with Merck KGaA, Darmstadt, Germany, I want to talk about a technology that could help bring the internet to more people and places… Smart Antennas!
You can find out more about Merck KGaA, Darmstadt, Germany’s Sustainables here:

Im only 11 years old . But im always learning basics abt science and GENETIC science . So this vedios are very helpful to me 😊 , thank you alex
This makes me so happy!! I’m so glad the videos are helpful and I love that you’re excited about science and genetics!!
I had never heard of liquid crystals being used in this way. That was very fascinating. Great video!
I’m so happy you liked it!! It was definitely new info for me too!
thanks for doing the talk today for UCSC chemistry club! it was amazing! love your videos too!
Thank you so much!! It was great chatting with you all, I hope it was helpful :)
Very informative. Thank you.
I'm so glad you enjoyed it!
thanks for the video ...keep going
Hey! I really love you content! I admire the way you explain science. I am a science student myself, I am struggling understanding statistics parts of research papers, I would love it if you could make a video on that
Wow, thank you
Perhaps a silly question on a video about electronics, but what sort of field are you in genetics-wise? Is it more creating new cells, or researching old ones?
I wish this technology could somehow improve the efficiency of stationary solar panels. In the end of the day, sunlight is also an electromagnetic wave.
Ohhhh, that's a really good point. I wonder if that would be possible one day.
Woa I hadn't even thought of that. Good point!
@@AlexDainisPhD Judging by the scientific publications on the topic of photovoltaics and light steering, it's possible to use liquid crystal layer as an integrated solar tracker. But the effectiveness of that approach is still a matter of debate. On one hand it leads to the simplification of an external solar tracker. On the other hand it reduces the overall optical transparency of the system. Besides, the maximum incident angle for which the light rays entering the optics is still very limited. So it seems there is a trade-off. Unfortunately, i couldn't find any commercially available prototypes of such solar cells. Anyway it was curious to dig into the topic!
I'm glad you did dig in! I wonder if we'll see that trade-off shift at all in the coming years to make it worth it.
Mechanically tracking antennas is a what my uncle’s 6ft-wide satellite dish used to do 30 years ago. Back then the satellites were not in a geosynchronous orbit so this was necessary and, as a result, changing channels would sometimes take 30+ seconds to lock into a channel being transmitted on a different satellite than the channel you were previously on (since each satellite can only transmit a limited number of channels). Then after that, if you hit the back button it would make you wait 30+ seconds again! 😂
Oh wow!!!! While I remember vividly my father using a broom to clean snow off our satellite dish decades ago, it definitely didn't move on it's own. That's so cool (but I'm also glad we're moving past that!)
Re: 7:10, the Tesla FSD beta has shown us that a high bandwidth internet connection is not needed for autonomous driving, so you focusing on the other positives was nice!
Speaking of Tesla, did SpaceX's and Starship's revolutionary pricing come up in the discussion? Starship's estimated pricing per kg enables a completely different magnitude of orbit applications. Have these recent rocket developments had an impact in the funding of smart antennas and such?
That didn't come up, but it's a great question! My naive assumption would be that as it gets cheaper to send payloads up, we're going to see more of all kinds of technology both being launched and connecting to things being launched. I'll have to look into that!
@@AlexDainisPhD speaking of tesla, have you heard of elon musk's Starlink?
en.wikipedia.org/wiki/Starlink
Yeah it was real weird SpaceX was never mentioned. Their new Starlink satelite internet constellation literally uses phased array antennas as the consumer ground reciever. It was kinda surreal watching the video talk _around_ it, while never mentioning it by name. It seemed deliberate, and rather deceptive tbh 😑, since it subtley implied this company invented phased arrays (used in fighter jets for DECADES, and even used in mobile phone towers thesedays) in a manner which would absolutely fool a layman who watched the vid.
@@roidroid So Dieter mentioned Starlink in our conversation (but not the SpaceX launch prices mentioned above) so I don't think he was trying to imply at all that Merck had invented that. I edited it that bit out just because I was trying to trim a 20 minute interview down to a few minutes, and that piece of the convo didn't make the cut, but I apologize if it seemed obvious to other people! This tech is all pretty new to me, so I tried to do my best to present it but might have missed some of the nuance that I would catch on a video about genetics!
@@AlexDainisPhD a follow up on starlink might be cool, since i don't really follow the tech news that closely but would really like to know if that project is going anywhere too.
I hope this will become commercially viable soon
Be amazing if the whole of humanity is connected to the internet

I thought this would be about artificial robotic insect-antennas.
Oh I would love that!!
i want that thing in my phone
Right? The current antennas are about the size of a pizza box, so are great for mounting on a car/boat/building/etc, but technology always gets smaller over time, so I have to imagine these will too!
Your local mobile phone tower already uses phased antenna arrays. They're not strictly omnidirectional 😉, they can direct their signal in the direction of your phone.
@@roidroid I did not know that! So cool! I learned so much making this video, I'm excited that people are still adding more to the convo here!
i like it ^^
Sorry but that just felt like an 100% #Ad - just selling your channel/audience to a company to use. I kept expecting the corp guy to go and Alex to add more independent thought... but no.
And it's not like phased array antennas are a new idea. They are just not that wide-spread yet. "Smart antennas" just sounds like marketing speak.
@@julietmike896 there certainly could have been more differentiation between the LED based antenna tech that this company owns, vs all the other basic concepts/ideas he went on to explain *as if he invented them too.*
But like Alex said: it's not her field, so she would have needed an *independant* consultant in the fact-checking chain to catch these corporate-PR induced problems.
Feedback received. I will keep all of this in mind moving forward, and always appreciate constructive criticism!
@@AlexDainisPhD I've been here from the start and I think this is the first time I've not liked one, so 148/149 ain't bad work.

But... you're my SME for bioengineering, let's talk about CRISPR/CAS-9, genetically modified bacteria and their applications in feedstock processing, any other applications, I don't want to loose you as my SME in real cool stuff, Technology based on inorganic chemistry it's not an issue for me, there's Neural Networks who can design antennas in a very efficient way, so there's no need to improve the material, just the way we think of them. BIO/GENETICS PLEASE !
There's still lots and lots of bio and genetics coming! But sometimes it's fun to stretch my brain a little bit and think about other fields too :)
