My biggest annoyance with Mimestream is that opening an email marks it as read; I want that status change only when I've actually read it, not just cruised by while navigating the inbox. Guess what? There's a setting for that. Yay!

One difference between Kitty Hawk and SPARC Q>1: It wasn't obvious during that early flight that there would be a commercial aviation industry. With net fusion energy, that promise and scale-up trajectory are clear. #FusionEnergy

Ten years later and MIT's Alcator C-Mod tokamak is *still* of use. I see new research papers circulating that include what we learned on C-Mod. For example, you can validate computer models to see if your simulations match actual results recorded on C-Mod. #FusionEnergy #Energy

This is what we mean when we say we've begun shifting our weight from our SPARC foot to our ARC power plant foot. SPARC is a big deal, but we're tackling the longer-term ARC work, too. #FusionEnergy

Or that it's one or the other, or that either is monolithic, or that there are not other influences involved. But still, just comparing those two very broadly is interesting.

Take a look at the plumbing that'll cool our magnets to 8 K (or 15 K or 80 K, in some cases). Superconducting magnets make our fusion machines possible, and cryogenics makes our magnets superconduct. #FusionEnergy

DDR = dry dress rehearsal = dry run × dress rehearsal. (A wet dress rehearsal for a rocket means you fuel up even though you don't launch.) Our DDR for SPARC will be like running a tokamak fusion pulse, but with just the support systems and no actual tokamak. #FusionEnergy
