I wonder how many people here are discovering tom7 for the first time beacuse of this video.

It’s like when you think of something that will never exist, because it is just too absurd. However, this guy not only has an even more absurd idea, he also brings it into existence and shows why it’s a great idea to build a sustainable future!

Some of these ideas are as old as time but the comic seriousness is great.

Reminds me of older analog delay circuits where the signal was sent as a sound wave in glass IIRC ... with multiple taps for different delays.

EDIT: Here's a cool example that maybe warrants its own submission: https://www.eevblog.com/forum/projects/glass-ultrasonic-dela...

The idea of buffering data by transmitting it somewhere far, bouncing it off a moon or whatnot, and using that distance of radio waves as your memory is my favourite thing ever.

Unfortunately due to free-space path loss limiting the Shannon-Hartley channel capacity, the total amount of information storable using this method asymptotically approaches zero for large distances. For reference, the combined formulas are C=d×B×log_2(1+(Dc÷4πdf)²×S÷N)÷c. And lim->∞ d×ln(1+1÷d²) unfortunately = 0. (Curiously, attempting to store more information by increasing bandwidth -- and thus center frequency -…

this lives in my head rent free for the rest of my life

Haha..., storing data volatile, with not good retrieval success, slow speed in thousands of heads... I wonder if you could make a harder drive out of this approach... And how much you could store there. And does it benefit society?

Like automatic phone calls..., texts... :-D

is there a TL;DW on this? I don't have the patience for these long drawn out videos with bad audio.

Unfortunately no. With a short attention span, you will just have to miss out on what makes his videos awesome. For this type of thing, making it accessible for you would ruin the magic.

Wait until you encounter his executable research paper about executable research papers.

The NAND gates video is probably the closest humanity will ever get to perfection though.

The soft limit is the size of a solar system, a practical one is the furthest and the biggest body in it, so... Jupiter/Saturn?
