Thanks Martyn … I had not seen that … I know and have worked with people from the Dubai Futures Foundation, but have not seen them since 2017 … looks a bit like Masdar City to me https://masdar.ae/en/masdar-city/the-city

… not where I would want to live but pretty impressive for a number of reasons … good experiment for learning also what not to do …

The point about retro-fitting might make sense in a desert state but in Europe we need to retrofit the existing cities as we would otherwise encroach on more farm land and nature reserves …
