I want to do a research in electrical engineering.
And I was thinking of system to eliminate phone chargers.
My idea is to convert sound energy into electric energy and then charge the phone using that. So you won’t have to plug your phone ever again. So your phone will be charging while you are talking!
Tell me if this makes sense guys….please!!!!

When electric power is distributed through the national grid, the nominal voltages are typically: 345, 138, 34.5, and 12.47kv. When voltages are higher then their typical nominal level, power can be saved from a reduction of line loss. Power saved = money saved. My Question: When increasing the voltage or conductor diameter from the standards today, what’s the maximum amount of money saved from minimizing line loss? Is it enough to be worth the investment of the cost of replacing higher rated equipment?

compound angle formulae in math involves all sorts of sine, cosine stuff e.g. sin(A + B) = sinAcosB + cosAsinB and i would like to know if you could use stuff like this practically for things like cutting wood where the intersecting components meet at angles when viewed on two different planes.
if there is a way, would it be possible to explain to an idiot like me? thanks
