Hydropolis uses biomass, solar and tidal energy

“Our main source of drinking water comes from rainwater collected on the roof of buildings. Water goes through gutters to flexible bags lying below each building and adapted to the volume of stored water. Associated, there are secondary bags that store non-potable water to be used in bathrooms and washing machines after appropriate treatment. Then, water is directed to bioreactors containing algae that apart from collecting the nutrients will also clean it and then drop the water slowly into the sea.

In extreme drought, when rain water is not available, there is an alternative system to ensure continuous operation of the city. 70% of the land surface is covered by water, and of those 70%, 97% is salt water so a water desalination system based on the distillation process was developed. The distillation process is based on the use of an oven system, with the support of a solar panel heats the salt water which, reaching the gaseous state, amounts to the pitched roof where it condenses and is collected in a new container while the salts remain in the original container.

Much of the energy of our city is obtained through biomass, solar and tidal ways:

The energy produced by solar panels is a result of the radiant solar energy conversion directly into electrical current through semiconductors. These panels are concentrated in square-shaped platforms of 10m side, with about 60 panels each one. Tidal energy comes through the oscillation of the waves. Regarding to biomass energy, this is generated by the decomposition of organic materials which gives rise to the methane gas that is easily used to generate electricity, heat. The techniques we use in our central are combustion, gasification and fermentation.

This new self-sustaining city planning solution allowed the human race to conquer new territories. We can keep the quality of life we were used to and at the same time reduce our ecological footprint. We hope we can re-tread firm territory in a near future.
