Is that Valve’s latest Steam console?

I suspect the added cost/environmental cost of adding a slightly more complicated setup than panel <-> fixed resistor, such as an mppt would be a worthy tradeoff.

I understand the point of the blog is to reduce the inputs to simplify, especially in eschewing batteries, but I suspect the loss in efficiency of not tracking the max power point would be significant.

I do like the concept though, in terms of shifting heat from daytime to later in the day, and localizing it into a box, rather than heating your whole house. It feels like the kind of thing you would put in your bedroom to help keep it warm into the evening.

I wonder how effective this would be at keeping the inside of a parked car or boat above the dew point.

The principle is similar to the Kotatsu, Korsi, or Brasero then, makes sense. I could see the way of improvements specific to the household's preference.

Sun? In the winter? Wish I had that too
