A recently published study estimates that up to 70 percent of the United States' electricity needs could be met through a newly devised system that harvests power from evaporation. This novel renewable power source uses bacterial spores to generate electricity and can sit on top of lakes and reservoirs.
Back in 2015, Ozgur Sahin and a team of scientists from Columbia University revealed an exciting new potential source of renewable energy. The team had created a way to generate energy from the natural process of evaporation using a certain type of bacterial spore. These spores expand and contract as they absorb evaporating moisture, and this oscillating motion could be harnessed to generate a small amount of power.

Forgot advantages d) and e) - you get a river in your space-city, which is not only pretty to look at, fun for watersports etc, but is a handy place to store vast amounts of life-giving water.
