The best thing about Diablo Immortal is that it is a fun, professionally crafted action-RPG befitting the Diablo name. The new Activision Blizzard game, launching on iOS and Android later on Wednesday and Windows PCs on Thursday, immediately impresses as one of the better smartphone-first action-RPG games on the market. And my 10 hours in its universe have thus far allayed my previous fears about its production values.

The worst thing about Diablo Immortal is its economy. My pre-release testing of the final game was regularly marked with menus and in-game characters alike selling me new types of "orbs," "stones," gold, and other confusing paths to microtransactions. At best, the game can be enjoyed despite this nonsense.

But the bean counters at Activision Blizzard aren't willing to offer a one-time purchase in Diablo Immortal for fair, nag-free adventuring. (Worse, as of press time, the game publisher appears to double down on a particular 2012 fiasco.) That's doubly tragic when the game is otherwise a fun, smartphone-friendly option for one more dungeon run—which leaves me stuck between recommending a perfectly fine smartphone adventure and warning about its ickiest caveats.

The world's first ammonia-powered zero-emissions tractor successfully completed its first demonstration run at the Advanced Energy Center at Stony Brook University in New York last week. The midsized John Deere tractor had its diesel engine replaced with an "ammonia to power" system developed by a startup called Amogy. The system converts the energy-dense chemical into hydrogen, which then powers a 100 kW hydrogen fuel cell.

Although most EV coverage is devoted to consumer-oriented passenger cars and light trucks, medium- and heavy-duty vehicles represent more than a quarter of US vehicle emissions and are important targets for decarbonization. The low-energy density of batteries and their long charging times make fuel cells an attractive zero-emissions solution, and we've looked at the potential uses for hydrogen fuel cells in trains, trucking, and mining in the past.

But even the greenest hydrogen still isn't very energy dense, and outside of California there's little hydrogen infrastructure to rely upon.
