I have no idea if its refered to as “energy density” but it doesnt really matter since my question wasn’t about terminology symantics.

I would argue that it would be more correct to use axles, because they are real rods which the dishes rotate around, and not imaginary lines.

Do they factor in how much space the units take up? Efficiency is good but energy density per square foot/meter of real estate is also important.

Axes (“ax-ees”) is the plural of axis and is used correctly in the article.

The spell checker didn’t catch it sew it must bee correct!
