Not NEOM but another ambitious eco-city. This time in Africa like Akon City.

Hollywood actor Idris Elba has a "big dream" for Sierra Leone, the West African nation where his father was born - to regenerate a beautiful island off its coast and turn it into an eco-friendly "smart city".  But as the idea was explored, a more innovative plan came into play - to bring in partners and seriously develop the area in a sustainable, eco way. The project now also intends to bring wind-powered renewable electricity for the first time to Sierra Leone.

The island had a population of around 30,000 people in 2013, when the latest available data was recorded - and is approximately 600 sq km (230 sq miles). That is a little bigger than the Isle of Man off the UK and about twice the size of Malta.

The project is to be financed through a public-private partnership, and the island will be designated a special economic zone with a separate legal and economic system from the rest of Sierra Leone.
