He mentions induction 'hot plates' towards the end, and says that they're limited to the same 1800W and 120V as kettles, but there are "commercial" portable induction stoves that are 220V and can go up to 3500 and 5000W; e.g.: * https://www.vevor.ca/induction-cooktop-c_10592/vevor-portable-commercial-induction-cooktop-3500w-countertop-burner-hot-plate-p_010340512175 https://www.vevor.ca/induction-cooktop-c_10592/vevor-portabl... * https://www.trueinduction.com/Commercial-Single-Induction-Cooktop.aspx https://www.trueinduction.com/Commercial-Single-Induction-Co...

In the US. In the UK 2200W induction plates are readily available with a standard plug for ~£40, or if you spend a little more you can go to 3kW - [0] which is about the limit of most domestic circuits but is hotter than most gas hobs. If you _really_ want more than that you can go a little mental and use one with an integrated battery which can push out 10 kW [1] [0] https://www.nisbets.co.uk/nisbets-essentials-single-zone-induction-hob/jb376?vatToggle=incvat https://www.nisbets.co.uk/nisbets-essentials-single-zone-ind...

  This begs the question, and I've genuinely thought this before, of why we don't just strap a battery to a kettle and end this silly debate. If it takes 5 minutes to boil a cup of water in a 1000 watt kettle, that's somewhere around 80Wh... I guess it would be kind of expensive, but couldn't you make a pretty fast kettle with some number of high discharge battery cells? (Well honestly, I guess the real answer is outside of Internet debates most people probably just don't consider 5 minutes to boil a cup of water to be a problem.)

    It would turn an inert device that costs a couple bucks to manufacture and has affectively no usage limit into a bomb that costs a couple hundred bucks (due to lack of economy of scale) and is limited by the battery's rated number of cycles. The battery's proximity to the heat source wouldn't help.

And I guess I could've solved my own problem by googling it. There are tons of battery kettles on the market, including a 1500W one by Cuisinart and a 2200W (apparently?) unit by Makita. The latter is predictably expensive but the Cuisinart is available for around $100 where I live, which is definitely pricey but seems plausible.

        > Obviously the battery should be replaceable. (It should be in most electronics, really...) This is super wasteful when we can just hook up a heating element to an insulated tank and keep it hot like Quooker [0] does. Assuming the 3L tank, that would mean probably 20 minutes to heat the tank if it's entirely emptied for the US, but that's how long it would take to boil that water with an electric kettle _anyway_. If you want 5l of water for cooking, you cna use your 3L tank and fill it up with the "slightly lukewarm water that keeps coming through the tap", and then put it on the hob _anyway_. In the best case you're boiling 2L of water instead of 5 anyway. > That doesn't seem like a particularly tricky problem to me. The standard kettle already tries as hard as possible to insulate the heat. If you were really worried it'd be possible to put the battery on a separate power brick instead probably. Dunno what kettle you're using but no kettle I've ever used has been insulated. They're either plastic, or stainless steel. They do usually have a lid, which helps.

    People that care about the time it takes to boil water just have an instant hot water boiler on (or under) their bench.

    Impulse Labs is doing exactly this.. I believe there master plan foresees a future where batteries are more integrated with a house for decentralized grid storage. But the additional consumer advantage is better hardware - i.e cooking time.
  - martythemaniak 11mo ago
    It's probably just the price of batteries. You can definitely do this and you'd need like 8 18650 batteries, which today you can get on amazon for $30 USD. A decade ago it might have cost $200-$300. Given that premium kettles already sell for about $100, there's definitely room for an ultra premium kettle that boils water laughably fast for $150.

    That seems a terrible waste of batteries to me. A boiling water tap seems like a better idea to me - electric heater with a pressurised insulated vessel that just dispenses from your tap.

Sure, but over in 230V-land 3500W hot plates are completely standard, and can plug into any regular wall socket. Same with microwaves and hot-air ovens: just put it anywhere on your kitchen countertop and plug it into the nearest socket. We do also have a "kitchen plug" for high-powered appliances. Those go up to 7.3kW in their regular dual-single-phase 16A version, 11kW when wired with three phases (quite common in households these days), or even 17kW with the (understandably) rarely-used 25A plug variant with three-phase wiring. And that's not even commercial equipment, just what you'd pick up at your local Best Buy equivalent. The commercial stuff uses CeeForm, which is a three-phase 16A/32A/63A/125A plug. Or it's getting hard-wired.

  What is the specific standard for domestic 16 A and 25 A 3-phase plugs you’re referring to?
  - maccard 11mo ago
    Not OP but - I can't answer the specific regs, but 16A/240V is absolutely bog standard for the UK and every high street store stocks ovens that will draw this down. They need to be on their own circuit, e.g. this [0]. I've never seen a single oven pull more than this, but devices like [1] are fairly common where you have two independent ovens in one, and it can pull 21A - this would necessitate the 25A supply. As for three phase - https://www.howdens.com/-/media/howdens/assets/clh_asset_products/clh_asset_levela_108973/clh_asset_levelb_110593/clh_asset_levelc_110596/ass_25627833.pdf https://www.howdens.com/-/media/howdens/assets/clh_asset_pro... this hob (which I have) will take 3-phase 16A, or single phase 32A.
