2) You take the supervisor to the basement and put one in his ear. Also duh. God damn are we running an intelligence agency or a kindergarden?

A single human on Mars could do in a week more than every previous rover on mars put together has accomplished to date.
Sure. And at only 100X the cost of all those missions, it would be such a bargain.
I wonder if my skydiving gear and wingsuit would count. I guess the sky is now my playground and they're the toys I always bring when I play in it.
The retail replacement cost is why it's insane to put it in your pants pockets.
"I just dropped a grand on this. I know, I'll subject it to huge forces and see what happens!"
Why would you do that?
I frankly don't see any difference. Big, fat force, tiny little space. That's not good for a sheet of glass, a sheet of metal—hell, you've seen what happens to a sheet of paper after spending all day in your pockets. People learn that in grade school.
If it really has to be on your waist somewhere, get a holster. Otherwise, just carry the damned thing, or put it in a shirt or coat pocket, briefcase, backpack, etc.
Since the '90s, I've never regularly carried a mobile device in my pants pockets. Obviously, it would break, or at least suffer a significantly reduced lifespan. On the rare occasions when I do pocket a device for a moment, it's just that—for a moment, while standing, to free both hands, and it is removed immediately afterward because I'm nervous the entire time that I'll forget, try to sit down, and crack the damned thing.
Who thinks it's okay to sit on their phone? Why do people think they ought to be able to? It literally makes no sense. It's an electronic device with a glass screen. If I handed someone a sheet of glass and said, "put this in your back pocket and sit on it!" they'd refuse.
But a phone? Oh, absolutely! Shit, wait, no! It broke?!?!
I was looking at LED replacement bulbs at the hardware store the other day ($20 each). I am suspect as to their efficiency.
Get a Kill-A-Watt meter and test the power consumption of LEDs youself. All the ones I've checked have used just about exactly what it says on the package.
They have large heat sinks on the which get very hot. That is wasted energy.
They have heat sinks because the LEDs need to stay very cool to work properly. Incandecent bulbs don't use heat sinks because they need to heat up to thousands of degrees just to get a small fraction of the photons they emit into the visible range. Now which do you think is wasting more energy?
There is no way to pack an efficient transformer into such a small space.
I doubt that any CFL or LED on the market is using a plain 60Hz transformer. They're using switching power supplies, which can be very efficient. That's becuase they crank the frequency up to a range where a small transformer *is* efficient.
Houses need wired seperately with a lower voltage appropriate for powering LED lights.
You'd still need a switching power supply to match the low voltage to the exact needs and wiring pattern of the particular LEDs. That's why most every PC have a separate power supply on the motherboard just inches away from the main power supply to convert 5VDC to whatever the processor needs.
Not to mention the power loss of low-voltage wires. If you put 100W of LED lights (about 6 bulbs) in a room at the end of a 50-foot run at 5V, you'd be pulling 20 amps. If you used 14AWG wire, at 0.25 ohms for the 100 foot round trip, you'd have a 5V voltage drop just from the resistance of the wire. You would also be violating code, which would require you to install a dedicated 12AWG circuit just to power 100W. That's obviously completely unworkable.
In summary, all of your uninformed "gut feel" opinions on these technical issues are unsurprisingly wrong.
