Hate to rain on this guy's parade, but conductive ink pens have already been for sale for quite some time. If he wants to reinvent the wheel, enjoy. Quite honestly, this looks amateuristic, so gefundenes Fressen for artists and "installations", I guess. Sorry for being so negative, it just feels unfair sometimes that hardware designers working their ass of to get you all these nice fancy iGadgets are rarely held in high esteem, while "artists" can "invent" something old, build something trivial (20 lights in parallel!) and makea big deal out of it.

The conductive ink plotter which was featured here some time ago is something completely different, of course.

That depends a bit on who is "we"... It may also be the Chinese or the Russians, meaning the US wil never get to see the moon ever again.

Anyway, while I assume your plan is not a serious suggestion, allow me to analyze it. For starters: the current non-geostationnary moon already does this to some extent, the spot is just changing all the time. More importantly, the reflectivity (or albedo) of the moon is 12%. This means that, at best, moonlight could be 8 times brighter than it is now. Currently the moon is about 250000 times dimmer than the sun, so in the best case your enhanced moon would still be 30000x dimmer than the sun...

On a side note: security was a lot more relaxed those days...

You are completely correct. In the past Heinz has even been caught cheating by underfilling their ketchup bottles.

Indeed, "I ride a virgin" sounds way better.

Actually, bidirectional, simultaneous transmissions using exactly the same polarisation, modulation etc have been possible for a long time, using circulators/hybrids and echo cancelers. I imagine they had limited succes because typically the power difference between transmitted and received signal is too high for the echo canceler to deal with, but in theory, this "holy grail" is certainly possible.

Apart from that, as you mention correctly, the novelty here is the size.

If you define full duplex in your own bizarre way, then, yes this is not full duplex. The more common definition, however, is that transmitting and receiving can be done simultaneously. And that is exactly what is going on here. Obviously using a shared channel, otherwise it would not be news. And even that is nothing new. Echo canceling and circulators have been existing for ages. The novelty here is the size of integration.

Pssst! Looks quite like the Dunning-Kruger effect.

Typically my ex GFs and I used a condom until we trusted each other enough to go for another contraceptive, which typically was The Pill. If she would have objected to this, for whatever reason, I would have been happy to keep using condoms. No sweat. Respect. Responsability, no problem. On the other hand, "forgetting" to take a pill, getting pregnant, not letting me know on time, not taking any other steps (morning after pill, whatever) wouldn't be very respectful either and would indeed piss me off.

He may have been much smarter than your average lad, but at the same time -if you pardon my French- Columbus was an arrogant idiot who went against the common (and correct) knowledge of those days by underestimating the circumference of the Earth by a factor of four. Afterwards he was hailed as the discoverer of America and blabla, but the matter of fact is that he would have drowned if it hadn't been for this random unpredicted piece of land (*) in the middle of the ocean.

(*) Actualy middle-agers made some predictions about undiscovered pieces of land that "should exist" based on some symmetry or whatever religious logic they used. This was not the case for America, though: Columbus really underestimated the voyage and thougt he had arrived in India. The fool!

Only if it is still inside the cow.

Publishing cartoons in a magazine one needs to buy in order to see them is not quite "pushing beliefs in someone else's face".
