Oh, I'm glad I don't work in the oven business. We're just starting a stealth startup that's revolutionizing dishwashers, and the prototypes are amazing. They use less water, less detergent, and this weekend we're hoping to solve the last remaining issue: occasionally, they break glasses.

I hope it's not the approach of using less water by not rinsing properly in the end, so people have to either eat soap or rinse everything manually afterwards, wasting far more water. I swear Bosch is so terrible at this.

  The innovation here is clearly edible soap. And the 'less water' claim is technically correct, but it doesn't mention the decamethylcyclopentasiloxane. Just because it's complicated to spell, you understand.

    Edible soap?! The solution is clearly edible dishes!
    - afandian 3mo ago
      Too late, already been done! https://stroodles.co.uk/collections https://stroodles.co.uk/collections I bought some edible cups out of curiosity a few years back. Nice for coffee. I did end up eating them all, although some of them were still dry at the time of consumption. I think edible soap has better behaviour-adjusted shelf-life here.

      Luckily our investors helped us out with the regulatory capture, so we don’t need to worry about the safety, just the palatability.

  Do you use rinse aid?
- tdeck 3mo ago
  Perhaps a match for the UK market? From what I've read they often don't rinse the soap off of dishes there (I wish I were making this up).
  - afandian 3mo ago
    Maybe it's the cause of our "bad teeth". (I heard the rumour too. But no-one I know fails to rinse the "washing up liquid" (as we call it) off their plates)
    - camtarn 3mo ago
      Sadly it's true. I've seen people just put the dishes in the dish rack and let the soap bubbles slide off them.

    If there was enough soap residue to matter you'd notice the taste.
- sfn42 3mo ago
  I recently learned that you should add detergent for the pre-wash rinse as well. May dishwashers have a separate pocket next to the detergent pocket, often there isn't even a lid on it or the lid has openings so the detergent falls out as soon as you close the door. If they don't have the symbolic pocket you can just pour some extra detergent anywhere, like just spill some outside the main pocket or pour it into the bottom. This allows the pre-wash cycle to get rid of most of the grease and stuff before the main cycle so the main cycle is more effective and the water is cleaner so the final rinse works better too.

It sounds like you're joking, but I've long dreamed of a different type of dishwasher. One that washes instantly. I don't need it to fit more than a single plate at one time. Just put something in from one end, and out comes clean and dry plate on the other end. Like a car wash. I am quite certain these exist already large kitchens and I seem to remember one from a school diner from maybe 35 years ago, but I've always been wondering why they don't exist on smaller scale.

  It can be accurately simulated with appropriate brushes and rags, water and soap, and a sufficient number of hands.
- afandian 3mo ago
  I don't know the first thing about dishwashers, but it seems obvious to me. The cycle-to-volume ratio is as bad as it could possibly be. Conventional dishwashers recirculate water as they wash and rinse. I imagine there's an mx + c formula to how much water is needed (c = enough water to prime the pump or whatever). So compared to a normal size load, you'd be wasting that constant amount of water. The wash is also likely going to follow mx+c (c = time for grease to break down, time to rinse, time to dry etc). You can wait a few hours for a whole set of crockery. Can you wait a few hours for a single plate? Commercial "passthrough" dishwashers work very differently. Manual mechanical action with a spray, plus a quick wash, sterilise and rinse. At that point why not wash your single plate by hand?
- askvictor 3mo ago
  I've long dreamed of a dishwasher that can detect when you remove the (cleaned) dishes from it, and presents a display saying 'load dishes' or something like that. And after finishing a cycle, says 'unload dishes'. Should be pretty easy to achieve with some load cells in the feet, but haven't seen any like that.
  - briHass 3mo ago
    Many modern ones have a door open sensor that allows for the dishwasher to display that dishes are clean after a cycle until the door is opened and fully closed again. That doesn't help, however, if users are lazy and don't unload the dishwasher after opening it to grab a clean plate or whatever. It's a nice feature that can be added with existing sensors and one line of logic in the uC. Another one I noticed recently is garage door openers with the photo transmitter/receiver ('beam') to stop the door if someone blocks it can use that same beam to turn on the light if broken when the door is up. Handy if entering a dark garage from outside.

Oh, I’m glad I don’t work in the oven or dishwasher business. We’re just starting a stealth startup that’s revolutionizing coding assistants, and the prototypes are amazing. They write code faster, explain it better, and this weekend we’re hoping to solve the last remaining issue: occasionally, they deploy to production.
- vntok 3mo ago
  This issue does not come from the coding assistant. In fact, humans will occasionally do the exact same thing as long as their tools have enough permissions to deploy to both local and prod from the same environment. Fix it by separating the tools (different non-interconnected VMs, etc for dev/qa/preprod/prod environments) and the permissions (different accounts, sessions, tokens, etc for the run/debug/test/deploy loops).

> less water, less detergent, I achieve the first two goals by simply scrubbing+rinsing dishes after most uses and letting them dry. No glued-on food to go gnarly. They go thru the dishwasher once in a while. It's my personal strategy for being eco without getting food poisoning, but I've never seen a paper that evaluates this method in comparison to more-typical workflows (i.e. in-sink wash-using-soap or in-dishwasher wash-using-soap).

  It's well known that what you're doing actually uses more water and detergent.

    Unless I have a LOT less than a full dishwasher load.

Are you really doing this? I’d like to speak with you, if so.
- eudamoniac 3mo ago
  It's a joke. The point being that dishwashers have to use more water and energy because breaking glass is the bottleneck of how hot and pressurized the water can be. The joke is that startup founders ignore tradeoffs and are trying to make an impossible product while marketing it as soon solved. Like "we found a way to increase voltage with no increase in watts! We are just trying to work around the decrease in amperage..."
  - DANmode 3mo ago
    What if you ozonated the water? I’ve seen laundry setups where the water is ozonated, and no detergent (or hot water!) is required to remove debris and oxidize oils and other gunk out of clothes.
kordlessagain 3mo ago
I'm 6'7". I absolutely hate bending over to unload the dishwasher. When I open a dishwasher, it should slide out and lift itself to cabinet height. And it should just hold an entire bottle of detergent so I don't have to put it in each time.
- albumen 3mo ago
  We installed our dishwasher at hip height, with the cupboard for clean dishes directly above. Bending down is a thing of the past. The two dishwashers idea is neat, but the cupboard capacity is greater than that of a second dishwasher; and we haven’t got the space!

In bars that cycle a lot of glassware they actually do seem to use high heat and break a lot of glasses. But it's fine, the restaurant just buys cheap (easily broken) glasses so it all works out.
