you can change temparture from mug

like if you have 20c coffee you can heat it to 30 for example

just shy 2 hours for overengineered stuff still

i doubt it can actualy heat heat stuff

or you can put soda there and cool it down

only change the temp in terms of 1-5*c

i cant wait for it to get chinked though

also like anything tastes good after 2 hours of contact with air

aromatics dissapear quite fast specialy from coffee and tea

but yeah

chinked incoming

like this concept is asking to get chinked

i cant wait for my xiaomemei mug

also things like that have existed(tried at least) for long ti,e

there is just no market nor use for them

only thing that might survive 2hours is cacao done in milk

and even that i would not drink after 2 hours

(aromatic evaporation wise)

but yeah we will see

i wouldnt mind paying like 20e for that

but 150e fuck no

+ taxes

and as i guessed

thats just peltier with "nice" looks

so easy to get chinked

with some powertuning/management

idea is the same that is just Highpower one for speed :D

>300*c coffee

i know there is 12v peltier-film

what is quite accurate

and those cost like 10dollars piece

time to make own startup

https://www.aliexpress.com/item/Creative-Thermos-Cup-Glass-Liner-Thermos-Mug-Garrafa-Termica-Coffee-Cup-Stainless-Steel-Vacuum-Flask-Mug/32568450631.html gives you idea

basic vacuum-glass thermos gives you 6-12 hours of heat until it starts to change (depending ofc outer and inner temperature at start)

and they promise only two :D

sure the heating/cooling peltier element acts as heatsink

and probly trains the battery damn fast on that first mug

due it needs to fight against its own thermal mass
