This is actually something that has been discussed in my house a LOT. Our thoughts and plans are pretty simple. We plan to use the solar panels to generate enough power to run the pumps/air a few hours each day, and to charge some batteries the rest of the day. The AP system is a 'stop-gap' for us. Something to add extra nutrients to our diets if and when things get really lean, until the soil gardens are producing more, or if some other unforeseen issue arises. But, this is a great thread and can and should open up some deep, thoughtful conversation...
