For those few of us not living in the deep South, should we consider a return to the 19th century fruit prison to grow those pesky crops when our weather is obstinate? It looks like very sustainable model, and they could easily double, with simple modifications, as a place to put your captives during shtf.
From the sixteenth to the twentieth century, urban farmers grew Mediterranean fruits and vegetables as far north as England and the Netherlands, using only renewable energy.
These crops were grown surrounded by massive "fruit walls", which stored the heat from the sun and released it at night, creating a microclimate that could increase the temperature by more than 10°C (18°F). Later, greenhouses built against the fruit walls further improved yields from solar energy alone.
It was only at the very end of the nineteenth century that the greenhouse turned into a fully glazed and artificially heated building where heat is lost almost instantaneously -- the complete opposite of the technology it evolved from.
THIS type of cell is good for keeping captives but is not so good for raising produce:
