Maybe the horizontal stabilizer trim can be replaced by a mobile weight inside the plane (moving along the front-to-back axis), that allows "trimming" the position of the center of mass.

According to official statistics [1], in 2022 Germany produced 33% of its electricy from coal (up from 30% coal in 2021). Of this coal, one third is brown coal. Judging from these numbers, the situation in Germany is a catastrophy from an

Visually the cockpit of a fighter plane is located forward, thus very likely ahead of the plane's CG. Ejecting the pilot would thus move the CG towards the back of the plane, which is a less stable configuration making it more difficul

Yes, and that might help the reaction. Also heating the tank to the optimum temperature (for the particular bacteria) helps, optimum pH, etc. helps. But the point is to provide the "help" with electricity directly.

And who has access to MI300 and MI250 GPUs? I would program for them, but I can't ever get one, or anyone I know can. How much does one MI300 cost, BTW? Is there a price published? are they available to buy anywhere?

I use GPUs for FP64 (64-bit floating point) compute, and the best AMD GPU right now is still Radeon VII, which was released in 2019. Since then AMD split the GPU business into two lines, CDNA and RDNA, the point being to be able to charge m
