Two features in this off-grid van (besides the MASSIVE power system) that are extra exciting are the under-counter, horizontal refrigerators/freezers and, brace yourself, the inside shower that recirculates/reuses water and purifies it with a UV light such that you can shower indefinitely with two gallons of water.
Why aren’t we putting water recirculating showers like that in our regular homes right now?
Okay, so the answer to my big question above is water regulations, namely, water in a shower must match drinking water quality. These laws vary from state to state in the USA, meaning anyone trying to building such a device might only be able to sell it in some states, and California has such high water standards that it’s just too expensive to bring this type of product to market in that state at all. Wow.
The van folks appear to have either sourced theirs from Europe, where they are ahead of us on such innovation, or possibly even building their own based on open-source developments in Finland.
