    I believe mailbox.org is all renewable, and I’m pretty sure it’s solar.

    But you need a massive battery bank to run stuff, batteries have a limited lifespan (especially the crap used in a UPS).

    It’s not cheap, you generally want to overbuild everything, and there are ongoing costs (hardware failures, batteries, etc).

    But it can be done. Just have to do the math for your max power draw, then how much uptime you need determines the size of your battery bank and number of panels (which is influenced by how much sun you get/how consistent it is). You need enough panels to run your system and charge batteries, given the limitations of sun availability.













  • Tires make all the difference. Both the size/proportion and materials.

    I’ve had RWD cars that were beasts in the snow (East Coast ice no less) because they were near perfect weight distribution and had the best winter tires on the market (Nokian).

    I’ve had AWD cars that sucked, because the car was poorly balanced, the tire sidewall was too small (so the tire can’t flex much), entry level winter tires (rubber was harder), and stupid electronic traction control that tried to out think the driver but just got in the way.

    RWD will still usually be more challenging to drive than AWD (I think even more so with RWD cars post 2000), though some AWD systems can be unpredictable. Part of the issue with newer RWD cars is the tire sizes - it can be hard to get proper winter tires (plus they cost a lot). I’ve seen some cars for which winter tires didn’t exist, or were exorbitantly expensive to get (it’s assumed by both car and tire manufacturers that these cars won’t be driven in snow).

    Fortunately Subaru uses a dead simple AWD system (basically open diffs at each end) - the most complex thing they do is use the brakes for traction control/torque distribution, which is less likely (In my experience) to get in the way than things like electronic diffs (can you tell I’m a fan of Subaru AWD?).
