Power Generation Technology

The Suiren Group's power-generation equipment research company developed a power-generation solution for the floating cities that used neither nuclear fusion nor solar energy, but geothermal energy.

That was right—geothermal energy.

More precisely, it was thermal energy from Venus's atmosphere.

At Venus's surface, the average atmospheric temperature ranged from 424°C to 462°C.

And Venus's atmospheric temperature happened to decrease progressively as altitude increased.

At an altitude of 100 kilometers, the average temperature was -112°C; below an altitude of 5 kilometers, the average temperature ranged from 424°C to 462°C.

The enormous temperature difference between the two provided the conditions for another power-generation solution: thermoelectric generation technology.

The design team intended to use small floating modules to place the heat-exchange system on the ground, then connect it to the floating cities with cables.

Then, at an altitude of 55 to 60 kilometers, where the average temperature ranged from 27°C to -10°C, they would install small heat-dissipation modules. Thermoelectric power could be generated during this heat-exchange process.

With a temperature difference of more than 400°C, it could fully support high-power generation.

This power-generation model also avoided the awkward limitations of solar panels.

After all, solar panels needed to be spread over vast areas, while winds in Venus's upper atmosphere were far too strong. Large solar-panel arrays would catch the wind too easily.

Moreover, solar-panel generation had to contend with the planet's alternating day and night cycle. Venus's rotation was incredibly slow—one full rotation took an average of 243 days.

That meant a single Venusian night lasted 121.5 days.

If floating cities used solar panels for power during operation, they had only two options: follow the sun each day, or build enormous carbon-powder energy-storage power stations.

Choosing the first option meant installing high-power engines to keep the floating cities constantly within the sunlight.
