"Boiled" is a bit subjective thing and it's possible the icon of contemporary design that mixes pop and postmodern styles produces enough steam for the fascinating mythological and futuristic creature - something in between a dragon and a flying dinosaur - to whistle at an earlier point than the as stylish as it is functional Dualit has enough to steam pressure to switch off.

What I think I've done is increase the surface area being heated and made the water shallower.
I have one of these https://uk.alessi.com/collections/kettles/products/tea-rex-kettle and it does boil quicker than one of these which I also have https://www.dualit.com/products/lite-jug-kettles
I was fascinated enough to do a race... the Alessi on the hob won by a significant amount. But yes I realise that the power draw is equal (silly smart house + Home Assistant + Grafana all said so), but still the Alessi boils sooner.
This will likely now send me down a wikipedia thermodynamics rabbit hole as I seek to understand the physics of it, but a quick hunch feels like it would be true that if one is increasing the contact area of the heated surface on the liquid and reducing the depth of the liquid, then it kinda makes sense it's accelerating the heating even for the same energy being applied (even if that energy is itself spread over a larger surface and less intense than the smaller surface). idk... will Google.
