I use ConjuGato on iOS for practicing Spanish conjugations. There’s a game mode where you’re given an infinitive/tense/person and think of the conjugation and you can filter it down to solely irregular verbs to learn the exception

With the staggering drop in the cost of renewables and grid-battery storage I just don't see how nuclear has a bright future in any regard. They're unbelievably capital intensive and have a mean construction time of 7.5 years [0].
