Use a wye delta starter to reduce starting current.

Starting current can be 5-8 times rated current for a 3-phase motor. You need to provide links to motor datasheet and generators.

Planes are moving a lot faster than cars.

This is a Q&A site. Where OP has a specific problem they wish to solve with hopefully a specific answer or answers. You have specific knowledge and are seeking a discussion, so no specific answer. Comments are just that, comments.

Regardless of the irony of my handle and your question, it's about the economics of steel and the US. Very little about engineering design. As in an engineering problem to solve. This would have more luck on an economics or US foreign policy forum. JMO

This is not the forum for your type of question since it is not about design but the economy of steel.

7.8m would be correct. Visualized.

Because PV-battery hybrid has battery storage for 4 hours, which would be smaller capacity than full storage.

In line with traffic movement, while other side has none. Counter vibration.

If electromagnet is powered by DC, no impact. AC possible.

300 MW / 60min/hr / 60 sec/min.

Gas Spring Calculator

You know the answer. Define range. As in, an input voltage range of 5-30V.

Like charges repel, so electrons would disperse over full volume / surface.

A nice answer for homework!

Water exits tank from the bottom and enters tank, via ground pumps, from the top. System is gravity fed. No pumps on exit so where would cavitation take place?

This question needs more context. Otherwise it is just opinions.
