Debug the specs "Much of the essence of building a program is in fact the debugging of the specification." ~Fred Brooks, American computer scientist and software engineer Replace the word program with #PowerConverter, and the statement would still be correct.

The latest data shows that 92.5% of all investments in new electricity generation capacity worldwide went into renewables. [This is for 2024 and comes from IRENA.]

continuing with my PEEC solver in Blender for inductors. Now I have a basic Python/Numba code that can calculate skin and proximity. You can see as the frequency increases the current shifts towards to the outer surface and also gets affected by adjacent turns #b3d #geometrynodes #electronics #Technology #science
