It looks like IoT device (almost all of them have USB) with one or more USB devices plugged in.
I'm not very familiar with these devices, but do they have their own OS inside or they
depend on host OS? If they do, then it is more complicated. If they have their own OS,
then Security could be potential weakness. Also not all USB ports have
power supply which matches the USB type specs. This could be an issue.
On the other hand if they are dirt cheap and mass produced, they might be quite good.

My idea is just use hundreds and hundreds of old laptops and PCs laying around and being
recycled constantly. They are abundant, cheap, versatile.
The problem there is the power usage, size and noise. Old machines use too much power
and are not that efficient.

I read a news about Mepкeл who set a target for 1 000 000 Electric car charging stations
till 2030 in Germany. I wander what if the charging of money for electricity happens automatically through
a blockchain wallet entered in the car's computer. It would be zero hassle while charging.
Also charging stations can mine coins or serve as uPlexa Utility nodes.

I'm sure the companies will want to build these stations as cheap as possible and running on blockchain
should be most automated and cheap option out there. So mining with Tesla or other EVs might be not wise,
but mining/staking/running a UPX node on the charging stations sounds too good to ignore.

Charging stations which will have a lot of constant (probably redundant) power supply, 100% of them will have internet (probably redundant) and on top
of that will be millions and quite spread throughout the world which is the best decentralization possible.

What do you guys think of that?
