I like showing off Star Trek TOS without all the fancy CG...

With the cap on, looking straight ahead, the bill blocks the top half of the display. The cap itself blocks much more than the GG display which is transparent. At least on me.

I can easily look through my GG at the road. You _can_, normally up and to the right in the visor as stated.

Conductive filament for 3d printers is imminent. One would still need a source of semiconductors.

WWII Panzer diesel motor generated electricity to power the motors that drove the wheels. So yes, but only 70 years ago.

Pole line stolen three different times last year by three differing thieves, several miles total. They all get caught because the scrap yard requires ID and imposes a delay. FYI, when the line goes down, speed is reduced until crews can arrive on the scene. What is needed is education because each successive thief is unknown to the previous one. No Darwin type evolution can take place because the thieves are completely independent of each other.

Here's a pic of the M60" searchlight, both visible and IR. Couldn't find a similar mount for the Abrams, it may be integrated.

I sense the candle flickering.

All the best Rob.

I recall reading an article that Mercedes(Daimler Benz) was playing around with one around 1984. It was on the cover of one of their magazines.

Different types of concrete also have an active content. Driving along the freeway you will see the levels rise while passing under a concrete bridge as the material is quite different than that of the the roadbed.

When pre-recorded CDs first came out I noticed that one could tell where the data ended. Only about 2/3's of the disc was used and I thought it would be slick to write the name/logo in this space. So I would place the CD on a plasma globe and position the blank area over a large plasma streamer. With the use of an insulated dental pick or small screwdriver, I was able to draw the plasma stream out of the globe through the CD, vaporizing the aluminum.
Kids: don't try this at home. You've been warned.

What happens when a coalition plane encounters an unauthorized aircraft? I cannot believe that radio contact is not initially attempted and that would be in the clear. Or just shoot first?

Unless under extreme pressure, doesn't a hydrogen reaction with oxygen create an implosion? A large volume of gas reduced to a few drops of water, the change in volume would indeed be violent. It's not any less powerful.

Back in my college days, the music history professor had an interesting story of the memory of the great conductor Zubin Mehta. While in rehearsal of a Beethoven symphony, he stopped and said that the note one of the players was incorrect and named the note it should be. The printed copy and the note played by the musician were correct per the copy. Apparently some time earlier, ZM was in Germany and had looked at the original manuscript. His memory of the note in question was validated when the original was re-consulted. It had been transcribed incorrectly all those years.

Give the railroads a tax incentive to install an additional line alongside their respective main lines complete with their own sidings. Only a single line - this will force the passenger trains to run on time in order to use the sidings to pass one another. No crossovers from freight to the passenger rails. The HSR agency would have to handle the metropolitan areas: building terminals, approaches and flyovers as needed. Done.
