Feasibility of Integrating Proof of Stake systems into everyday devices? Back in the days of Bitcoin mining there was talk of turning toasters or other electronic devices into Bitcoin mining machines, but that doesn't seem like a good idea anymore having that it requires lots of power and very low ROI having to run it as a node by itself.

My question is, has there been any discussions or projects that use a Proof-of-Stake coin or system integrated into another internet connected device? I'm not talking about just setting up a raspberry pi and installing a POS node onto it and leaving it to mine.
The use of other devices to mine bitcoin probably came from the desire to do something useful with the heat that mining creates.  It takes a lot of energy to slow cook a pot of chili, so the thought was that instead of using traditional heating elements, use SHA256 ASICs.  Regardless of whether the electricity cost was less than the amount of bitcoin mined...you'd still cook your chili.  It was energy you were going to spend anyways, so any amount of bitcoin you mined was just an offset to your existing chili-cooking costs.

I don't think this concept translates to proof-of-stake mining, because I don't see the benefit.  Would you store funds on your toaster, which in turn proves it has a certain stake in the network?  What benefit would this provide over simply proving stake with a computer?  When there is no heat to find a use for, this concept falls apart.
