With Starlink internet, data is continuously being sent between a ground dish and a Starlink satellite orbiting 550km above. Furthermore, the Starlink satellite zooms across the sky at 27,000km/hr! How can the dish and satellite maintain a continuous connection? And then how is data sent back and forth? Well, in this video we're going to dive into the inner workings for the ground dish and Starlink satellites, and see how a beam of data is formed, how this beam is swept across the sky, and then finally what exactly is in that beam that allows for incredibly fast internet! This is an incredible feat of technology and engineering, so stick around!

Erratum: At 2m50s, the orbits are inaccurate. The TV satellite should be in geostationary orbit moving in the same direction as the Earth. Furthermore, all the Starlink satellites should be orbiting West to East. Credit to Paul S.
He could easily add a Lightning address in the description for each video. Those using Alby browser extension will automatically see that the site accepts bitcoin tips. Or those not already using Alby can copy and paste the Lightning address and send a tip to it. Also, for Alby users, he could add a Meta tag on his website.
very interesting

Ooh, that's nice! Now, how do we get them to do that for Bitcoin & the Lightning network?

And he could add a Lightning widget on the website as well:

I meant how do we convince him that he should make one of those great videos about bitcoin & lightning?
Oh, sorry!! I just assumed you were referring to the Patreon.
He certainly is talented in explaining complicated subjects. Would be good to see that some day!
