There is also the potential to run off the TV while driving. Not sure if the electrical
math would work out, lot would depend on the charging system of the tow vehicle. I could see being able to get even a couple hours of nap time in AC comfort while parked in Wal-Mart or rest area as useful.
Not sure but it would seem that a pair of batteries with either a small generator
to recharge batteries and assume load might work out to 8 hrs. of AC for 4 hrs. of generator
time. I think 100 watt solar panel
yields around 31 watt hrs. a day.
Have to consider AC only draws full power when cooling cycle is running. Not a continuous draw at that rate. What temperature you set AC to maintain, ambient temperature, insulation, sun vs. shade all go into what will work. This unit seems like it at least makes off grid AC more feasible than it has been.
Less weight, lower profile, smaller generator required, can use fan from house battery as powered vent when boondocking
or as AC unit hooked up to shore power. With possible use of air conditioner via DC power. Hmmm interesting, very interesting. But not stupid. < said in Arte Johnson voice>
