Spanish couple Juanma and Tony have been living in a converted van of only 5 m² for nearly four years. They left behind rising rents and utility bills, investing €8,000 in the van and €3,000 in its conversion. Energy independence comes from a 400W solar panel and a 200Ah lithium battery. Annual butane consumption is two cylinders; heating runs on diesel. The couple reports health improvements due to reduced stress.
