How much innovation has there been in the ballpoint pen in the last decade?

1. How much of the math is memorized versus just knowing where to look for answers?

2. Hypothetical: you have no access to paid tools for things like FEM and CFD, how do you accomplish your hobby project?

3. Solar panel challenge: What would you produce as a physical, marketable product of value as passive income based upon a mostly self contained system powered by a single solar panel? You may add precursors, but may not interact further until the cycle is complete. There is no other temporal constraint.

How do you know when the grid needs more power? Does a bell ding?

How long does it take to ramp up from cold?

Texas has a private energy grid and it sucks. How could you sell them on standardized energy?

I assume there's some sort of main relay that connects the turbine/generator/hampsterwheel to the grid. I suspect this relay might be more beefy than the ones I've worked with in 24V, 230V and 400V systems...

How is a relay of powerplant-beefidity constructed so that the contacts aren't welded from the current upon initial contact?

How much would it cost to update the US power grid?

How much would we save in reduced costs?

This is all just so you can kill-a-what? isn't it?

How would your power plant be involved in a cold start of the grid and have you ever participated in one before?
