    I've seen the math here:
    https://www.ted.com/talks/davi...

    Dr. MacKay is using the United Kingdom as an example but it would be easy to extrapolate to France or any other 1st world nation. He gives some examples in his talk.

    The "Cliff Notes" version is this:
    Nuclear power produces 1000 W/m^2. Wind, solar, and other renewable energy sources produce something like 2.5 to 20 W/m^2. Consumption for UK, France, and many other European nations is about 1 W/m^2. So, if France wants to meet energy demands with wind, sun, and rain then they will have to cover at somewhere between 5% and 20% of it's land area with renewable energy producers. Or, they can use some other nation's land area, like Libya, if they ask nicely.

    Using nuclear, on the other hand, takes very little of France's land, and that is where they get much of their energy now.

    I'm pretty sure that the French are insane. If you have a counter example then please share with the rest of the class.

    PS, Fukushima's problem was a lack of properly sited generators, which meant they were damaged in the Tsunami, which means that you can't assume that some hypothetical battery storage will work either.

    I know that, you know that, but do think a gaggle of reporters know that? Or that they care? They'll eat it up like a trained dog getting a treat after doing a trick if it thinks it would please their masters, or they'll scream and run like frightened chickens if they think it serves them. Get a media darling like Musk involved and they'll likely find a reason to make this "a good thing".

    And Vogtle? I'm familiar with it's recent troubles. As I recall Obama went there to speak about the future of nuclear power being bright, maybe that was a different nuclear reactor. Anyway, Obama changed his tune a bit on nuclear power after the election. Then Fukushima happened and shortly after Obama and his appointees kneecapped it. I keep hearing about how expensive nuclear power is, usually from Democrat politicians, when it's Democrat politicians making it so expensive. It's easy to make nuclear power expensive when you can throw wrenches in the works for six years. Nobody knows if it could have been made on time and under budget now. Fukushima was irrelevant to the safety of Vogtle, it's not on a fault line, or near the ocean.

    You have it about right. My point is that as useful as a big battery can be to wind and solar it can be just as useful, or even more so, to nuclear power.

    Big complaints on the use of nuclear power is safety and it's inability to load follow. A big battery would be helpful in addressing both issues.

    I'll admit my knowledge may be dated so if you can provide a current source I'd appreciate it. Just looking at Wikipedia I see (in round numbers): 25% brown coal, 20% "hard coal" (not sure what that means), 15% nuclear, 10% natural gas, and 35% from renewable wind/hydro/bio/solar. (I know, not 100%, I said I rounded.)

    So a plurality of electricity comes from brown coal. A majority or very large minority from fossil fuels. Maybe half from "zero carbon" nuclear and other? If Germany has been spending decades getting off of burning brown coal then they've been doing it VERY slowly, or were burning just mountains of the stuff for a long time. You'd think that they'd be doing a bit better than this after making such a fuss about it, don't you?

    In the USA, by comparison, is roughly 1/3rd each, coal, natural gas, and "zero carbon" sources. Natural gas produces almost half the carbon as coal, and very little sulfur and other pollutants. On the balance the USA seems to be dong pretty good on it's carbon footprint, Id think. A lot of that has to do with nuclear power. We may have stagnated on nuclear but we don't plant on going backwards like many other places in the world.

    It was written in their Koran, that all nations which had not acknowledged the Prophet were sinners, whom it was the right and duty of the faithful to plunder and enslave; and that every mussulman who was slain in this warfare was sure to go to paradise. He said, also, that the man who was the first to board a vessel had one slave over and above his share, and that when they sprang to the deck of an enemy's ship, every sailor held a dagger in each hand and a third in his mouth; which usually struck such terror into the foe that they cried out for quarter at once.

    That was in 1786, the USA that we know today did not exist until 1789. They've been at war with the USA even before it existed. I'd rather they didn't get our money to continue that war. Without their petrodollars they'd likely revert to their habits from the 600s. I'm not too concerned about why they hack each other to pieces so long as they do it over there.

    I look forward to the day we don't have to care about what some sultan says about the price of oil. With the USA exporting oil now that day may come very soon.

    How do Americans finish high school knowing literally nothing about the world outside their borders ?

    To get government money US high schools have to teach American history, not world history. I studied computer science and engineering in college, so it's not like I had to know any history to graduate. I did however take electives in Spanish (not history exactly but we had to know something about the Spanish culture to pass), Western History (centered on Europe from 1789 to 1989), and a course on the history of technology, so I consider myself likely to be better educated about world history than the average American, as pathetic that might sound to you. Since there was not a lot of technology exported from the Middle East I didn't concern myself with what happened there, except when it intersected with America and Europe. Seems to me that things are generally peachy for us Americans so long as there is not one unified empire there.

    I like this, this is good news for nuclear power.

    Imagine a Q&A during an announcement of breaking ground on a new nuclear power plant.

    Reporter: Would you care to comment on the recent meltdown at the Springfield nuclear power plant?
    Person at podium: Oh, that was terrible and I feel sad for all those people displaced and otherwise affected. However we've made a deal with Tesla for their new battery backup system so nothing like that can happen here. We'll have enough reserve power on site to run the lights, computers, sensors, fire fighting systems, and cooling pumps for two days.

    People believe new batteries are what wind and solar need to be replace coal and nuclear power. I believe that technology like this will help nuclear power more than it could wind or solar. A lack of a power source capable of running the cooling pumps was what killed the reactors at Fukushima. Chernobyl didn't have such a problem but that was (effectively) an experimental dual use (for energy or weapons production) reactor, it also lacked a protective dome that would be required had it been built anywhere else. Any new reactor would not likely even need a separate power source to shutdown safely but a big battery like this would be very useful for peak load management. It'd also look good to regulators, to the public, and look good for Tesla.

    (Yes, I realize that I typed "power" when "energy" would be (more) correct, I just imagine that's how someone at a podium would speak to reporters.)

Global warming was at or near the bottom of the list, right next to their ability to get a good cell phone signal while they drive.

    A lot of these issues currently have solutions in opposition to global warming solutions. If people want to fight global warming AND have low prices on food and fuel, jobs for everyone, clean air and water, then they need to get over their irrational fear of nuclear power.

    There must be a lot of insanity in France if they think that they can both reduce nuclear power use while reducing their reliance on coal and oil. I've seen the math and the only way to do that now is with a bunch of solar collectors in Africa and wires run under the sea to France.

    Right, not a new idea., just not common. The link you gave shows an example of a pretty typical electric drive system for large vehicles. Not a hybrid since there is no means to provide electric power except from the engines on board. I do see how that could be he basis of a series hybrid though.

    What I described would be called a parallel-series mild hybrid. As I propose using a relatively small electric motor it could not operate (for long at least) without the ICE running. Chevy offered something similar in their light trucks to what I proposed for a while but sales weren't great so it did not last long. Shifting the primary driver from the ICE to the electric motor and you have something like the Chevy Volt. I'm having trouble verifying it but as I recall the Volt had a simple single speed transmission, it could engage a direct link from the ICE to the wheels only when cruising. This was to improve efficiency further while not adding significant weight with a full size ICE and multiple speed transmission.

    We were shifting from fossil fuels more than 50 years ago. Alcohol prohibition put a wrench in those works. Now if you want to run something on ethanol you have ATF breathing down your neck just looking for a reason to shut you down. Sure, you can find 85% ethanol and no ATF around. That's because the big companies with a bunch of lawyers got the licenses and such from the ATF and nothing leaves the property until it's mixed with enough gasoline, methanol, or whatever to make it poisonous for human consumption. Not that it stops the determined from distilling it back out.

    I believe that ethanol is a really bad idea but if we want to actually see if it would work we need a market free enough that people can experiment. I used to get together with people that did electric car conversions, bio-diesel, and other such things. Regulations on this stuff started to thin out those willing to do this stuff. That was a long time ago and my getting a different job required that I move so I lost track of those people. I still run into people doing this stuff but not as often as I used to.

    A government plan to shift from fossil fuels is good, I guess. I just think that less government would get us there faster.
