If you talk about 'consumer' electronics, you are speaking about a product that is designed for a climate controlled room. My interest in this was the 'server in a box' outside. Even still you can't heat sink something when the ambient temp is above the limit! Also, if outside the North East area can and does drop significantly below the limits. Talking about adding things to make it's environment within range multiplies it's cost.<br>
<br>My view was of a stand alone battery/solar system, which the Dream Plug 2 won't work. I think I see a bunch of software developers discussing software and ignoring the hardware side of it. The picture I have is that the Dream Plug 2, although fascinating, will not work in over 80% of the areas.<br>

</div>In my experience that's the standard, *officially supported* range for<br>
most consumer hardware; industrial (and of course militay) grade<br>
hardware may have wider supported range, but they also have<br>
significant higher prices.<br>

</div>Well, freezing temperatures should not be a problem because such<br>
hardware should usually be kept indoors anyway, and you don't<br>
want your home to really freeze for other more pressing reasons<br>
(burst pipes etc.); the real problem is heat in the areas<br>
of the world that get > 40 C and don't have widespread AC for<br>
the homes (which is probably also an area were there would<br>
be problems affording industrial grade hardware)<br>

</div>In my opinion a more cost-effective solution would be to continue<br>
using consumer grade hardware, but work (maybe with the help<br>
of the free hardware community) on custom, low cost, optional<br>
cooling system(s) for the choosen hardware.<br>
In some cases this could be just as simple as opening/changing the<br>
case, or possibly adding a wider passive cooling surface,<br>
except for the more extreme *indoor* temperatures where<br>
some active component will be needed.<br>
