THE BROWNWALL POWERWALL

From the Office of Civic Digestion — a report to the American home. The Brown Home program offers every family a battery it can build itself, from the compost it already makes. The Brownwall Powerwall — a wall of working compost, laced with water coils, its core at a steady sixty degrees centigrade. The coils carry the warmth indoors. One thermometer tells the story. Four cubic meters give four, even five, kilowatt-hours of heat a day, for eight weeks. Then the battery retires as fertilizer, and you build the next. At dusk, the warmth comes home. The Brownwall never idles — and neither does the American family. The full findings are on file at literalshitposts dot com. Build within your figures.
