Tsui Design & Research created the San Francisco Bay Area Development Plan which established growth projections of infrastructure, population, commuter traffic, urban growth rates, traffic congestion, pollution, greenbelt areas, job growth, and residential development rates for San Francisco Bay Area cities well into the years 2000, 2005, 2010 and 2020. Recommendations were implemented without harming existing ecology and preserving green park areas.  The Nexus Mobile Floating Sea City incorporates special ecological technology and self-sufficient energy systems. Two-mile high Sky City Tower is powered by the sun, wind, and atmospheric pressure differentials. This design prevents the destructive effects of urban sprawl by creating a vertically directed growth structure protecting the natural environment for public recreational use
