on 02026-05-15#video on muscle-powered #mechanical cement-stabilized compressed soil brick #construction machine by Makiga Engineering Services of #Kenya, designed to make interlocking blocks that are stable even without mortar (though, I’d think, a bit fragile), at a rate of about one per minute with four workers. Costs 122 thousand shillings. The outside of the bricks do have beveled (chamfers) corners, but their interlocking features lack not just chamfers but even draft. #compressed-earth
