This would be a hell of a hot power bank. It uses about as much power as my oven. So probably more like inside a huge cooling device outside the house. Or integrated into the heating system of the house.

To be fair, 2.5kW does sound too much for a single 3x3cm chip, it would probably melt.
Yeah, though I suppose once we get properly 3d silicon I would not be surprised at power rating for that, 3cm^3 would be something to behold.
