Combined with the Road article that indicates 13M acres of available roadsides - and bale density of 110 kg/m3, [1] - and a bale yield of approximately 2 dry tons per acre [2] - we have:

  1. 26 million tons of bales
  2. 236 million cubic meters of bales
  3. 19" straw bales (~50 cm) - R27 [3]
  4. One cubic meter of bale gives about 2 square meters of wall insulation.
  5. Take Seed Home - 3000 sf of wall (all-enclosing) or 300 m2, or 150 cubic meters of bale.
  6. This suffices for about 1.6M new homes.
