The hyperbole above shows how you can get from enough for a day or two, to more than enough to sustain a family for a week. It happens very gradually and as long as the room is available it is not self-regulating. I really do need to downsize a bit -- too much redundancy.

Meanwhile I added an inflatable LUCI Lux Inflatable LED Solar Lantern light to the kit ... Very nice light, thanks for the tip.
