At cloud-top level, temperature, pressure, and gravity are all close to Earth-normal, and breathing-air is buoyant.
Numerous materials can be extracted from the outside air, including oxygen, hydrogen, carbon, sulfur, nitrogen, and even some metals.
A day/night cycle is about 100 hours, depending on how close you are to a pole.
A nuclear reactor is as simple as a big fabric tube suspended vertically with a naked atomic pile hanging near the bottom, and a wind turbine turning in an opening at the top, the only moving part.
You need something non-solar because nights are long.
Alternatively, you can store energy with a weight on a cable attached to a generator. Play it out to discharge, winch it back up to charge.
Or maybe different layers of atmosphere circulate at different rates. If so, you can hang a wind turbine in the next layer below.
