Where I live, in the boondocks of N Cal., we usually have a few days of power outage a year. On those rare occasions when there's an outage and a clear sky, we get to see this. There's nothing like sitting in your hot tub, looking up at the night sky FULL of stars, and watching the international space station get re-supplied, and noticing how many satellites cross it's path every orbit. I feel like we should have at least one 'blackout' night per year worldwide, where we do our best to not use outdoor lights in an effort to show this beautiful expanse of nature to those who never get to see it.

My thought was actually to have multiple projectors per block approximately 10 feet up (building mounted) with sensors to identify people and have them 'place' a smallish ball of light at about 8-10 feet up that floats above and in front of them, but with much less light needed than a 'street light'...and maybe stationary one's in intersections (these could even have 'covers' to stop wasted light from going up). Or, it could project tiny lights (like in the video) near ground level to illuminate the sidewalk, but that's not as useful by far.
By my estimation, there could be less pollution because there would be fewer, smaller lights on at any one time (where normal lights are just ON all night). I agree, there are many issues to solve, but it's doable if thought about thoroughly.
It's a little too late to worry about 'light pollution'...in fact I bet it's not on the average person's radar. Sadly, many people in cities have never seen stars at night and don't have a clue how much is hidden from them. (I live in the boonies of far N cali, and we still have light pollution from nearby towns, but nothing like in a city...I've even watched the international space station get re-supplied while sitting in my hot tub! That was amazing!).

Get on UP! Hot tub!

Oh Bob. It's better to remain silent and let people think you an idiot than to open your mouth and prove it.
97% is not the same thing as 97. Also, the correct number is really closer to 99.9% of all published climatologists, if not higher. Those who know, know. Those who believe don't know jack.
There are many ways to differentiate human produced CO2 from naturally occurring CO2, and therefore prove the rise is due to man. This has been done repeatedly and conclusively. The simplest way is to simply look at the graph of the rise and compare it to our use of fossil fuels, they are exactly the same curve at exactly the same time, with exactly the same dips and bumps. It's certainly not the only method, but is a simple to understand one.
It's ridiculous to state that to live 'green' you must live as if in a 3rd world country. That is simply BS stated by unreasonable men without any knowledge (and usually with a financial incentive to be anti-green/pro-fossil fuel).
It's also ridiculously ignorant to state that being 'green' is not cost effective. As someone who has had a solar system for 7+ years, I can tell you it's paid for itself already (with an estimated 13 more years before needing serious upkeep), has kept me away from the 40-50% rate raises that have happened to others in that time, it heats my house, my shower, and my hot tub and keeps the lights, TV, washer/drier, dishwasher, and fridge on when the grid goes down. It's not at all the expensive, powerless, sacrifice forcing technology you seem to think it is. It saves money even in the short term, and significant amounts in the long term AND has many other benefits. You've been listening to the wrong people about this issue, people who either totally don't know what they're talking about or are bold faced liars. I speak from actual experience.
Cost effective 'green' technologies have existed for well over a decade. You are simply wrong about your estimations.

Yes, it is way better.
1). First, that toilet isn't going to spill over. Ever had that happen? And with a heat register near by? Disgusting.
2). Two, do you realize how much Feces is splashed around the bathroom when you plunge? Not just on your floor, but walls, and on you, your clothes and possibly your face. It's not just the big drops, but the little ones, the ones that practically become airborne.
3). Three, Clean up afterwards, once you're done with a plunger, you need to clean it off, and if there is stuff sticking to it, as you can guess, that's not fun either. Not to mention, where are you going to clean it? in the bathtub? After you sanitize the plunger, now you have to sanitize the tub, or sink, or what ever as well.

-You're going to need to wipe down that toilet whether you plunge or use this sheet.
-This plastic sheet, looks strong enough that it's not going to break.
-And disposing it. Well, lifting it into a garbage bag, that just seems way easier.

Never saw my granny ever drink water. Diet coke, iced tea, and crappy merlot (w/ice and sweetener) every once inna while. She was one if those 'fish fuck in it' folks, if you mentioned a glass of water to her she'd always get the same wince on her face...

Celebrate World Water Day with hot tub sex or bathing in a public fountain.

C'mon, there is absolutely nothing wrong with cookies or icecream, provided you're not shoveling a tub of icecream or a packet of cookies down your kids several times a week.

Too much = bad. None = a different kind of bad.

....ever sit in a hot tub for a while, and then decide it's time to go back into the actual pool.

...and then go "Holy Balls, this pool is FREEZING"

That is why your comment will not work, and would instead be, from "augh!" to "AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"

I once logged onto chatroulette and after a few spins saw a headless man sitting in a tub, cradling a shotgun. To this day I don't know if this scene was real or not. I wanted to report it but didn't know how.

A tub made from carbon fiber? How does carbon fiber interact with different types of acid?

Just curious, of course. It's not like I would want to dissolve anything in it. Certainly not my neighbour who was up at 5am this morning, sawing wood in his backyard...
