 i hate induction heating, give me carbon fuel any day, it's very crappy tech and the devices use clunky, noisy circuits not the kind of smooth, dynamic algorithms i would design and that's not easy to translate to hardware without some heavy capacitors and arrays of capacitors and FETs etc

anyhow, i'm not saying ecash isn't useful, but it has two big, clear, and obvious deficiencies that make the mint a trusted third party and if you don't use a limited set of denominations, totally identifiable metadata

build some tools to fix those two problems, and both are related, and i'm in 
 all forms of electrical heating are based on magnetic force causing deformation in materials (almost always ferromagnetic) or electric  force (such as through carbon) and they are highly inefficient at releasing energy compared to burning carbon directly, and most forms are readily available near anyone anywhere, be it charcoal, wood, coal, gas, or oil

there is no sense in centralizing the use of carbon based heat release technologies to drive kinetic force to again convert it back to heat, because the heat sources are cheaper to just deliver to my house instead, and don't get me started on the bullshit of using heat pumps for indoor environment control with the ridiculous nonsense that causes, eg damp winter microclimates outdoors and dessicated skin indoors (in bulgaria, where reverse cycle AC is the norm for winter heating every office has ultrasonic humidifiers!)

if it has to be electric, then at least use carbon resistance to make IR and point the emitters towards the humans, but it's bullshit

better, close the windows, insulate the walls, add mass that actually stores heat, cook with gas, gas is the best, outstanding quality cooking heat, and don't build buildings with north facing windows for fucks sake 
 Might be that induction devices are crappy and clunky because of the manufacturers standard fiat mindset of cost reduction.

Regardin clunky, to bring it back to ecash, with all its drawbacks, it could be a very smooth payment method. Where lots of internet payment methods bring a lot of clunkiness, like the elaborate but unsafe credit card authorisation or all the blockchain or node-related mess of other cryptopayments. 
 yes but if the mint knows who issues and who spends it's not private, stop saying it's private, it's not private

that would require some more complex coding of denominations and mixing processes, and it's no big deal but i knew there was something missing from the story 
 Did I say private?
