I would love a faster dishwasher -- not because I need the dishes washed faster, but becuase I live in an open-plan flat with the kitchen and living room in the same space, and anything to reduce how long I have the dishwasher churning away would be wonderful. Fortuanately, I tend to get away with a 30-min wash for most days, but someone please invent a 10-minute dishwasher please :)

YMMV, but our Bosch dishwasher has 5 modes and one of them is "party" mode. When selected, the machine first preheats water for 30 minutes and then you can load it repeatedly, each load only takes 10 minutes to wash. It does have two drawbacks though. First, you have to use liquid detergent, as tablets do not dissolve fast enough. Second, it consumes a lot of power and water as opposed to the regular 3h+ setting. But…
Sounds interesting. The water isn't metered where I live, so using more water doesn't matter. If it could be connected to the 70 C hot water outlet as well.. that would be even better.

Plus powercuts, plus them drifting.
If you have a clock that shuts off when the power is cut, you don't need to worry about drifting: Most of those are synchronized to the grid, and the grid keeps time really, really well. They actually synchronize the grid to atomic clocks etc for that purpose.

1. they’re really de-greasers, you have to pre-wash the plates 2. the surfactants used are suspected to destroy the gut barrier, because they aren’t being washed off for speed reasons, unlike consumer models
You need to rinse off what you put in if there is a lot of stuff on it, not because it will not be cleaned (it probably will) but because you don't want to have to clean that out of the machine at the end of the night. What does it mean for the gut barrier to be destroyed? I've worked in such kitchens in the past and there wasn't any material change in how I digest food or how sick I get, so I would suspect it's not…
MrBuddyCasino has linked the paper in a comment next to mine. I don't know enough to decide the credibility of the science itself, but that is the one people are referring to.
The only thing I want to add is that it is not a danger for people working with the machine, but for the people eating from the plates cleaned by such machine.
And in addition the concern is that the chemical used by the commercial machines cause chronic issues in some people after repeated exposure. Clearly if everyone who eats at a commercial kitchen would get immediately sick that would be very easy to detect. You don't need scientist to tell you that. So instead of thinking in black and white think in probabilities. The proposed mechanism is that some people (who were either pre-disposed genetically, or got a larger amount of the chemicals for some reason, or both) gets sick after a longer amount of time.

Chronic inflamation disease.

Dishwashers in commercial kitchens are rapid, much less than 10 mins. I have always wondered why, exactly, we can't have that at home. A dishwasher so fast that it's done while you're still clearing up from dinner and you can put stuff away immediately would be fantastic and is clearly absolutely possible.
> I have always wondered why, exactly, we can't have that at home. You can. It’s just way less efficient, way noisier, and way more expensive. A Hobart conveyor dishwasher has a cycle time south of 3mn (and throughput of 3 racks/mn, with conveyor speeds reaching 6ft/mn). But it’d probably take most of your kitchen and blow up your electric panel (they need an exclusive 208V 3-phase, and if you plonk for the booster h…
Also you need much more electricity, because you need to make a lot of hot water in a very short time.

elbow gease, is just a part of the routine. You cook, you eat and you clean.
I really dislike this article and fundamentally disagree. Sure, some engineers need to be looking at the problems people have or the products they're trying to buy or whatever, but that's not why I'm here. The goal, especially when starting out, is to: 1. Obsessively understand, improve and optimise everything, knowing that many of the results will not make it into real products or if they do will flop; and 2. Invent…
You can live by the advice you're giving, but if it doesn't end with you having built something people actually want, you won't have a viable business (if that is indeed your goal)

Home dishwashers are:
delicate: do you want to replace all your dishware with horeca dishware?
quiet: nobody cares how loud commercials are , they aren't in the customers ear shot
energy-saving: commercial require 30A instead of 15A of home ones
aren't fast: how much it can clean for a 120 seconds?

It reminds me of a Neal Stephenson quote from Zodiac:
"Most of my colleagues go on backpacking trips when they have to do some thinking. I go to a good hardware store and head for the oiliest, dustiest corners. … If they're really good, they don't hassle me. They let me wander around and think. Young hardware clerks have a lot of hubris. They think they can help you find anything…. Old hardware clerks have learned the hard way that nothing in a hardware store ever gets bought for its nominal purpose. You buy something that was designed to do one thing, and you use it for another."
If you build stuff you will sooner or later realize that when tools that can do new tricks turn up, it provides you with new opportunities that perhaps you didn't think of before.
If you own equipment to make holes you know that there is a vast difference between a spade bit and a forstner bit. They are two very fundamentally different ways of making a hole. Both make holes, but one will make an absolute mess of certain materials. If all you have is a spade bit, then for some tasks, you have to come up with a different strategies for achieving what you want. You have to design yourself around the limitation. If you use a forstner bit, its ability to make clean holes may mean that not only can you use it for making holes - you may be able to use it in situations where you are not primarily making a hole, but removing a curved bit of material.
I want a faster dishwasher because a faster dishwasher would solve actual problems for me. But it is a bit more nuanced than that. My dishwasher spends about an hour on one load. Getting it down to 50 minutes or even 40 wouldn't change anything. But if you can get it down to 10-15 minutes, it really starts to matter. It means the way I sequence tasks in the kitchen can change. And that's for everyday use. If I were to have a dinner with a lot of guests it would also mean that I'd need fewer plates because I can wash plates between courses.
I've been to a few design thinking workshops, and the thing that always gets me is how arrogantly stupid a lot of these workshops end up being. They pretend to be about learning the customer's needs rapidly, but more often than not what happens is that people try to replace actual insight with ceremonies and suppositions only to arrive at either the wrong conclusions or be in such a hurry to demonstrate cleverness that you miss most opportunities.
But hey, there is good money in teaching ceremony.
