Wow! The first ever image of a black hole was leaked before tomorrow’s big announcement... Proof that black holes have hair #EHTblackhole

Unlike stars, tokamaks have a density limit. @Andrew_Maris, a graduate student at @MIT, used machine learning and DIII-D data to determine that the density limit is strongly dependent on plasma edge temperature, an important insight for future fusion power plants. @APSphysics

@TokCOMPASS I see, thanks for the info!

@Andrew_Maris Not yet, it should be approved later this year

New time plan for commissioning and exploitation of ITER #fec2023

:D

Tokamaks may one day provide a nearly inexhaustible source of carbon-free energy, but our paper shows that we must urgently confront the challenges of disruption avoidance, mitigation, resilience, and repair twitter.com/Andrew_Maris/s…

In the meantime, our paper provides flexible framework that can be paired with assumptions about (or future models of) disruptions to estimate costs and/or estimate the maximum allowable disruption rate

Tokamaks are touted as the most promising path to fusion energy, but will “disruptions” kill the concept? In our recent open-access paper, we take a hard look at the challenges that disruptions impose on the economic viability of tokamak power plants tandfonline.com/doi/full/10.10…

@Andercot @VicenteValenz @pad_jules From what I understand, the other challenges for stellarators are 1) the high aspect ratio, which would force the capital cost of any stellarator power plant to be extremely high, and 2) designing magnets compatible with a DT blanket. Has there been any progress on these fronts?

Tokamaks are easier to design and build, harder to operate. Stellarators are very difficult to design and build, much more stable operation. Fortunately, our design tools have gotten a lot better, for both simulation and programmatic / parametric design and modeling of design features.

Take the blue-pill, and you go back to sleep thinking Tokamaks are the best magnetic confinement fusion reactor. Take the red-pill and I'll explain how stellarators are the ideal plasma configuration for grid-scale energy

@TheLovinator Especially since Cedar Rapids and Des Moines have good flags!

Iowa City needs a city flag

@FlagsForGood Yeah sure!

@Andrew_Maris Can we DM about this?

Quite a fun video about American state flags! Would recommend giving it a watch. Growing up, I wished my home state, NJ would adopt a better flag (left). Back in college, a buddy and I came up with new design (right) and even met with our representatives about it!

@GreenwoodKL Ah good catch!

@Andrew_Maris The final design has a five pointed star.
