There probably is a better or more general notation system, but specifically for western music it is actually pretty efficient and logical once you start working with it a bit. Just don't put too much weight on the names and think in intervals. You have a scale made up of 7 notes/intervals with the "fifth" simply being the fifth note in the scale. Same with third, etc.
The specific flavor (major/minor) of e.g. the third you're playing usually depends on the mode, but it is still a "third" and serves the same-ish function.
Extending the names i think would actually be more confusing. I'd argue it already puts the patterns of scales and chords in the foreground.
do you have a source for the >10x? because that was my assumption as well, but after reading through [0-3] i'm pretty amazed how cheap solar and wind have become over the last years.
The average price I paid for electricity in Ontario over a couple years vs. the average of a number of sources I found for cost of electricity across Germany. I don't have any links saved, but yeah it was like ~0.05 CAD vs 0.55 CAD per kWh iirc.
You're right that solar has become very price competitive. We're pushing that at Tesla & I do think as the current regulatory environment around nuclear continues to stay roughly the same, solar will be much cheaper in the coming decade.
It should be noted that subsidies, regulatory fees, and economies of scale play a MUCH larger role in the LCOE of energy sources today than the fundamental physics, efficiency, material costs etc do.
Therefore it is wiser to look at the options from a first principles perspective and consider the potential costs of sources after equally large effort is put into scaling and optimization, and ignoring political factors. When you analyze the options in this way, nuclear wins every single time.
also got a 2015 and 4k @60hz is possible plug and play with a thunderbolt to displayport cable. anything other than default scaling gets a bit choppy though
