Biochar priority areas

If I had to prioritise Biochar for household and communities I would suggest the following main applications:

Biochar for
- bioenergy
    - biochar-producing TLUD stoves for cooking and water pasteurisation/boiling (to kill water-borne pathogens)
- water filtration
    - gravity fed Biochar filtration for a final treatment step if toxic and/or carcinogenic chemicals are present eg. PFAS 'forever chemicals', agricultural herbicides and pesticides and more...
- Atmospheric Water Harvesting (AWH) 'Hydrogels' if no other water source (experimental, see web page on this site)
- sanitation
    - Biochar in urine/piss buckets
    - Biochar and bokashi humanure toilets
- hygiene
    - Biochar added to ?ethanol-based liquid soap for hand washing
- growing systems
    - biochar-based media for seedling raising
    - hybrid swale and Zai pit systems (Kenya) for biochar-based Regenerative Agroforestry Systems (RAS)
- building
    - hemp(char)crete preformed panels for, eg. 6 or 8 sided yurts 
    - hemp(char)crete load-bearing building blocks
    - charclay bricks
    - besser blocks made from charcrete
    - Biochar filled floor tiles
    - Biochar filled roof tiles

    - Biochar paint (great for indoor temperature and humidity control)
    - Biochar filled bench tops and more...
    - Biochar air filtration if in an environment with poor air quality eg.cities/urban areas, agricultural areas still   using open air burning practices

I should also mention too that biochar, in some cases, can be used in a cascade of uses.

eg. air filtration->water filtration->sanitation->growing systems (permanent Carbon sink)

eg2. air filtration->water filtration (community scale)->building (permanent Carbon sink)

Biochar production technology
    - small scale
        - TLUD stoves eg. Navigator series (see web page on this site)
    - small to medium scale
        - Kon-Tiki cone kilns (see KTE web page on this site)
    - medium scale
        - Flame Cap 'Algorithm' Panel Kiln (see web page on this site)
    - large scale
        - batch
        - continuous
        - many options!

That's all for now!
