Yes so. Decreasing losses is the only reason for using high voltages on power lines.
unless the F1 car weight limit has been waived
otherwise it doesn't matter that the cabling weighs more (to have the same losses as with a higher voltage system)
I think the argument towards higher voltage lies elsewhere (there's a lot of elsewheres)
I believe you are wrong.
IMO higher the voltage, higher the efficiency of the whole system. Drawback is that higher voltage requires better insulation, but still it's worth it.
We are talking about hundreds of amps.
Do we know what the change in Amperes are? I'm no electro-magician, but the way I understand it is an increase in volts doesn't mean an increase in Amps (its the opposite actually). Amps are the amount of electricity through the circuit, Volts are the measure of the force, or the “volume”. The resistance in the circuit will determine how many amps are being pushed. The wattage (the actual workload) will be Amps x Volts. The way I understand it, increasing the voltage like they are doing will allow them to reduce the current, making the system more efficient. This could allow them to run the power for longer stretches, recharging time is reduced, therefore giving them more power.
Again, I may be way off here. This is all just my theory based on the limited knowledge of electronics I have (one of my college electives I took just for fun).
