It's not efficient. At scale, you'd try to be orders of magnitude more efficient. This is specifically for portability & low maintenace (not needing to keep swapping/handling filters). If you're on a boat it should keep you alive, with some modest solar. But most everyday consumers have far larger water needs & trying to generate all that desalinated water via this process is not effective.
