Pengfei appears on the reviewer 2 podcast to discuss this paper https://open.spotify.com/episode/2qNxBiuHJI5zWET2GXSy9u?si=62YxobEeT7CjNtjch2cWuw&utm_source=native-share-menu&dl_branch=1
I'm curious as to whether one could implement this idea using truck bombs, or possibly air launched bombs like the MOAB https://en.m.wikipedia.org/wiki/GBU-43/B_MOAB Here's a video of a sulphur based thermobaric charge. The plume isn't very sooty, but that can be fixed https://youtu.be/xsWrfWJOu4Q I'm wondering if you could mix up sulphur powder with inexpensive ANFO booster, and possibly with liquid oxygen, to make a sooty mushroom cloud that is dark enough to lift (in sunlight) to the stratosphere. Getting the mushroom cloud out the boundary layer should be feasible. Here's a combat video showing a plume that probably makes it https://youtu.be/7GzDceVdpMI Here's another combat video, showing differently formulated explosives, giving a much darker plume https://youtu.be/v9r0u3dY48o I'd welcome ideas on this, particularly from chemists and engineers with explosives experience.
