  • Nuclear is not intermittent and can maintain very stable turbine rotation though, which is great if you want to have a stable grid.

    Wind energy requires either a very stable high-power backup (not only due to intermittency, but also variable output frequency), or losses to AC-DC-AC conversion and issues associated with inverters and sensitive motor-based devices.

    Solar is intermittent and needs inverters, too.

    So, all have their place. Some solutions do emerge, like pumped hydro storage, which both buffers intermittency and allows to directly obtain AC power with desired characteristics, but they’re not universally applicable and can fail through long no-power streaks.






  • Yes, normally the harmless strains of Penicillium roqueforti or something of the like.

    We do use molds in food and pharmaceutical industry, not all of them are bad. Aspergillus oryzae, for example, is used to produce soy sauce, miso, and sake, and Aspergillus niger is a likely source of citric acid you have in your kitchen cabinet.

    Natural pizza mold, however, contains nasty kinds of Penicillium, as well as Rhizopus stolonifer causing severe infections in respiratory system, mouth, nose, and face. Most cases can be treated in a hospital environment, but some are fatal, especially in immunocompromised individuals.
