We can both agree that solar is trash. I guess a bioreactor is efficient, but after having 3 battery chargers, a Moonpool, 2 Water Filter Systems, and a Power Cell Chaerger, it gets out numbered. Nuclear, way higher PUPM (Power Units Per Minute) but is way too expensive as well as its fuel source. It's also very late game and I still don't have all the parts. I had to build 4 bioreactors for all the power and I've hooked up the power transmitters at the geyser. To be fair it has a lower PUPM/Capacity Ratio, but you don't lose all of that space and titanium through the bioreactors. If you get a good farm going, and have easy access to places like the Bulb/Koosh Zone Aerogel is easy to make. All the other resources are pretty easy to find. You do make good points, but in terms of efficiency and accessibility I win, but through affordability and PUPM(with a slightly lower quantity)the bioreactor plays out. Nuclear reactor has both perks, but with WAY LESS AFFORDIBILITY and access. Also it is extremely late game.
