Thanks for the response, good that you're addressing this, there needs to be more of this kind of info put out on Medium, especially on the "line loss, intermittency, and storage" problem. A news item the other day was that wind/solar projects are delayed because our infrastructure is not ready to take the power (awaiting HVDC lines or storage). Here is another article of mine, I'm sure you already know most but it contains a 2017 Energy Usage diagram. Note that actually about 2/3 of all electricity generated is "lost" (mostly to heat loss in transmission lines).

Solar/batteries not perfect either (some "loss" is simply standby or inefficiency at point of use), but rooftop solar offers a HUGE advantage in point of use proximity, offsetting much line loss. Depending on the distance of transmission, HVDC may decrease loss up to about 50%. Because of time zones and high speed of electricity, a transcontinental HVDC line from CA to NY could transmit our solar at 3 pm to them at peak use (around 6 pm) efficiently. As such, kind of a way to shuttle power around nationally w less loss & w/o costly storage.

Things like line loss, intermittency, energy densities are not as sexy as Teslas, windfarms and Mohave photovoltaic arrays, but the whole thing is held up by lack of efficiencies and costly storage (plus politics like Texas wanting its own separate grid).

Thanks for tackling these subjects, I agree that nuclear fusion has been "the near future of energy" for my entire life! (67 years)

Re: Jets etc, I wrote this about hydrogen conversion (there are issues, but feasible)

Much that avg person doesn't know, big oil dragging feet, etc. Let's keep these articles coming!

PS-I read and responded to your nuclear power plant article
