The process is called Multiple Effects Distillation https://en.wikipedia.org/wiki/Multiple-effect_distillation

It is a commercially successful process. For example Hitachi have build 8 plants delivering a total of 8,600m3/day https://www.hitachizosen.co.jp/english/products/products011....

That's really cool. Thanks! I should point out, though, that I meant that I don't think you will get efficient enough to make solar power reasonable. You will notice that Hitachi's RO solution has higher power efficiency than the distillation solution. I'd be really curious to see how much power it actually uses, though... Unfortunately it doesn't say in their marketing material.
