It bothers me that you want to educate people but you are being so combative and smug. This isn’t the way to change people’s minds. All you are doing is making people feel personally attacked and driving them further away from having an open mind.
This is the first I’ve heard of HVDC, my experience is with typical AC transmission that makes up most of the current grid. Not a lot of experience, but college physics level.
US high voltage transmission is usually AC in one of the following voltages: 345 kV, 500 kV, or 765 kV. I used the 765 kV worst case losses of 1.1% per 100 miles (according to American Electric Power Transmission Facts Q12) which is over generous since most transmission would likely not be using only the high efficiency lines.
Also, transmission range is affected by load and high load reduces line capability.
We’re talking about moving a huge amount of power across 3000 miles. In my experience transmitting power across a nation as large as the US is unheard of.
You also seemed to have missed my point about how much excess power would be required to power the opposite side of the country (in the dark) while basically at dusk. Let’s say 30% of the east coast’s power comes from solar. That would mean that the West Coast would need to provide that 30% excess on top of their current energy demands during a relatively high demand time period. It would also be a bit unfair for the West Coast to be the ones responsible for over-provisioning to accommodate the east coast.
Is HVDC even installed and able to transmit across the US now?
For me Tunic perfectly captured that sense of wider and magic that I felt as a kid experiencing adventure games for the first time. Hyper Light Drifter and Outer Wilds gave me a bit of that as well. I highly recommend all three if you are looking for a similar experience.
