A converted Dina 93 bus has been presented in Xalapa, Veracruz, as a motorhome with full electrical, water and food self-sufficiency, according to its owner Humberto Besso. Solar panels and the bus alternator provide power: sunny days yield up to three days of electricity, while cloudy weather requires running the engine. Wastewater from the washing machine, kitchen sink and shower passes through bacterial treatment, is pumped to the roof and filtered through tezontle, activated carbon and reed. The dry toilet uses black soldier fly larvae frass instead of sawdust, and a small garden on board grows six plants, including tomatoes and radishes.
