A proposed pyramid city for the Dubai desert will stand 1.2 kilometres in height. The solar-powered pyramid was announced this week by Timelinks, an eco-design firm that plans to unveil the engineering wonder at Cityscape Dubai later this year. \'The pyramid will be more than a kilometre tall and will house one million people inside,\' a source close to the project told XPRESS. \'It will be completely self-sustainable.'
