> After five minutes of that, the machine would then fill the chamber with hot water for a three-minute ultrasonic bath. This was followed by a two-minute hot rinse cycle. Next, the chamber would drain and the user was blasted with warm air to dry off. They were additionally exposed to both infrared and ultraviolet light to kill germs. All in all, it was a 15-minute cycle.
It's apparently also a tanning booth.
15 minutes means it takes about 3 times longer than a shower, and it doesn't seem to do your hair.
- maronato 2y agoAnd uses orders of magnitude more water
- TeMPOraL 2y agoIs that a problem though? The other day I got a whole lecture on HN, complete with math, proving that keeping the water running entire time while showering isn't meaningfully wasteful... I still can't believe it on an emotional level, but the math checks out...
- MrDrMcCoy 2y agoLink?
- distances 2y agoWas that about water, or about energy spent on heating the water? My gut feeling is that keeping the water running would roughly double the amount of water, so double the energy.
- eru 2y agoYes, unless you take cold showers.
- bayindirh 2y agoA nominal water aerator limits water around 5L-6L/min levels. For every minute I don't use the water, I spend approximately two full kettles of water. With every 5L of water I can - Cook 4 servings (~400 grams) of pasta. - Brew 5L of tea/coffee - Water all the plants at home two times. - Possibly wash most of my handwash-only dishes in one go. - etc. So it's not not meaningfully wasteful. However, I can't turn off the water in the winter, because I feel very cold otherwise. However, this doesn't mean I don't waste any water or happy about what I'm doing. My only (half) relief is this water is somehow processed and reused by city for other needs, at least one more time.
- eru 2y agoWell, even if the city doesn't re-use the water, it doesn't just disappear.
- bayindirh 2y agoYeah, but getting rid of chemicals and returning it to a non-poisonous state for the nature is a big plus. You can't dump everything to the soil and say "that's your problem now, nature. Cope!".
- eru 2y agoYes, I mean when you are 'wasting water' you are mostly wasting the effort it takes to clean the water. Not the water itself. As opposed to eg 'wasting petrol', where the petrol really is gone afterwards. At least it has been chemically transformed.
- shepherdjerred 2y ago> You can't dump everything to the soil and say "that's your problem now, nature. Cope!". Nature couldn't care less. Nature works on much larger timescales than humans. It's the humans that are impacted. Just like climate change, plastic, and all other environmental issues -- humans are paying (or will pay) the price, not nature.
- eru 2y agoWhat's meaningfully wasteful depends entirely where and when you are, and how plentiful water is locally at the moment.
- bayindirh 2y agoI don't think so. Just because you're not in a water-stressed place doesn't make you eligible to keep taps open 24/7. This mentality is what brought us to today.
- eru 2y agoWho is 'us' and what do you mean by 'today'? And what do you mean by 'eligible'? In most places I've been to, you just pay your water bill, and then you can leave your taps running. It's about as productive as buying bread just to toss it in the trash, of course.
- bayindirh 2y agous: the humanity in general, today: the state of world water stress level [0], [1], eligible: the correctness of the thing you are doing regardless of the legality of the thing you're doing. IOW, "I pay the bill, now get off my lawn" is something you can do. But should you really do it, just because you can do it?

- eru 2y agoHow would conserving water in, say, Germany help with water stress in Australia?

- tobyhinloopen 2y agoIt doesn’t use any water. It just makes the water dirtier.
- maronato 2y agoAnd it doesn’t use any electricity either. It just moves electrons around.
- ExoticPearTree 2y agoFor a man sure, you can do your hair in 2 minutes. But if you’re a woman it is going to be a multiple of 15 minutes.
- phinnaeus 2y agoThis thing doesn't wash your hair though.
- nameequalsmain 2y agoI'm a man but washing and using conditioner will take a lot longer than 2 minutes. I have very long hair though.
- deleted 2y ago[deleted]
- voidfunc 2y agoIt's really more of a long-hair vs short-hair thing than a gender thing. I've had short hair and right now I have long hair. Long hair is a bitch between washing and drying.
- ale42 2y agoDepends on how much hair the man still have... some will definitely not do it in 2 minutes. And most women I know don't need 15 minutes to wash their hair.
- ExoticPearTree 2y agoLet's see: shampoo, rinse, mask, wait 30-60mins, rinse, conditioner, rinse.
- idiomaddict 2y agoDo you think every woman does this regularly without pay? My entire shower takes 8 minutes as a woman.
- OldSchool 2y agoOuch, the germicidal UVC is even more hazardous than the UVA and UVB tanning rays!
- xg15 2y agoI suppose, one advantage would be that you can use it while almost asleep, while you need a minimum of mental presence for a shower. So if you wanted, you could: wake up; slump into the bathroom and into this thing; press the button; snooze another 15 minutes while part of your morning routine is being done for (or to) you. Whether this is something you should do is another question... (Also, it might be possible to extend it with hair washing if you mount one of those barber sinks at the top and then somehow automate it. Exercise left for the reader.)
- fecal_henge 2y agoYour vision lacks the ultimate destination: This will replace the bed.
- xg15 2y agoThat sounds like that one guy a few years ago who wanted to replace all kitchen cupboards with dishwashers. Gonna steer clear of those directions. All things in moderation, etc.
- fecal_henge 2y agoI replaced all my wardrobes with washing machines.
- danudey 2y agoIf you replace some of them with clothes dryers then you can not only have clean clothes, but also dry and not-musty clothes. Highly recommend.
- devit 2y agoI think this works. You can buy two small dishwashers, keep clean stuff in one, dirty in the other, then run the dirty one and swap. Or you can also just have one plate and wash it by hand after every meal.
- eru 2y agoYou are right that for able bodied people it's at best a gimmick. But it might be useful for people with limited mobility, who don't want to depend on other people washing them.
- bell-cot 2y agoSafely getting into and out of it looks very challenging for people with limited mobility. But the article's final photo is of completely different model - far more accessible, far safer, and for "the health care sector".
- eru 2y agoYes, the original prototype is obviously just there to show off the models. I was thinking about more practical and less sexy versions that might actually see production.
- evoke4908 2y agoYeah, for a production model you'd likely see the chamber dropped down to a reasonable height, and whatever is in the pedestal can be hidden behind an adjacent wall or under the floor or something. There's no real reason it needs to be up on that pedestal apart from just being visually impressive
- shiroiushi 2y agoIt's probably only that tall so onlookers can gawk at the pretty women's bodies inside through the transparent sides. If it were sitting on the ground, you wouldn't get such a great view. A normal model would just sit on the floor.
- eek2121 2y agoGimmick? Maybe, I’d love to try something like this.It may not save time, but i bet it feels glorious.
- eru 2y ago> It may not save time, but i bet it feels glorious. Hence it's a gimmick. Though I bet it would get old really fast.
