The advent of electric vehicles has ushered in a huge selection of vehicles that no longer depend on gasoline. The advent of better solar panels and better storage batteries offer more options for independent transportation. The availability of systems to draw water from the air and of hydroponics to enable growing food in any location adds to the possibility of creating a motor home that never needs to stop for anything.
Those factors allowed me to create a design with all those features. I am now actively seeking my first client.
