The problem is you can't bring back girls.
One of my grandchildren has just qualified as a wind turbine service engineer working for Vesta. The newest monsters he is working on are amazing, they have elevators, bunks, lavatories and showers.
That is interesting. I understand why they have an elevator, but what is the point of the bunks, lavatories and shower? Why not bring a trailer for that purpose? (A caravan, I believe they are called in the UK.) Do they need a technician on site at all times? If so, it seems like it would be cheaper to install a small prefab house or trailer . . . errr. . . caravan.
Or is this an offshore installation? That would make it even more challenging to bring back girls.
Hi Jed.
It's not in all of them apparently, but where there's a cluster of next generation wind turbines on a ridge or moor then at least one will have such an arrangement since maintenance can apparently require longer periods of observation to fond out (for example) why the blade feathering systems or rotor brakes are malfunctioning. And if you end up 80 miles from home and 10 miles from anywhere on a dark and stormy night it's probably useful. Rural France is not famously accessible to random travellers. I have no doubt some engineers have camper (winnebagos) vans though.

Winnebago? Is that what you young people call it these days? (The bringing back girls thing . . .)
This is off topic and politically incorrect, but I read a WWII memoir by an RAF pilot. He and his fellow pilots had a beat up old car they bought for 10 pounds. Only the driver side door worked. The back doors would not open from the inside. They called it the Wren Trap. And if you know what that means, you are old.
I will never watch a video with such a silly title. Solar and wind work fine. Also large flow batteries built with cheap iron are now available for energy buffering.
Of course A LENR reactor would be ideal!
Watch the video and then we can discuss. The arguments are solid and logical.

I think the “will not work” is constrained to the condition “for achieving net zero”. I install solar panels in almost every irrigation project I design and build, and they work very well, albeit they are a “pain in the neck” to keep clean.
Probably a better way to say it would be "Why wind and solar will not work as well as we told you it would"? Lots of brilliant engineers on this. As pointed out by the author, there are regional, cross border, sharing schemes that could even out the demand/production imbalances as they arise. That is as far as I watched, and will finish later.
The conclusion is that the sharing schemes, even when shared across the entire continental United States does not solve the problem.
It’s a very well thought out and logically presented argument. If you choose not to watch it you are showing your cognitive dissonance.
Curbina nobody said wind and solar don’t work. The point of this analysis is that there is no path to net zero with wind and solar without bankrupting the global economy.

And I would agree to that, these are technologies that have a niche, but when it comes to ner zero, we are far from it being realistic.
Some form of nuclear will be absolutely essential to wean us off of fossil fuels. It’s delusional to think otherwise. Beware of groupthink.
Technology – Powerful and protected by nature – Dual Fluid (dual-fluid.com) is one of the ICCF25 sponsors. Konrad Czerski (ICCF25 organizer) is Dual Fluid's "Senior Research Officer" and co-inventor of the tech. I don't believe this is LENR related, although using spent nuclear fuel to power the reactor core reminds me of Global Energy Corp ( http://www.gec.solutions/ ). Still on the drawing board according to them, but if it works out as hoped, it could be a game changer...if LENR doesn't beat them to it:
Had a quick read of the Dual-Fuel white paper. My first thought was 'WTF can they build that thing from?' - and towards the end of the paper (attached) they say:-
"it will be a manageable task to identify and develop the most suitable material."
This suggests to me that so far this is an entirely theoretical concept that in the event of someone giving them the cash will need to be engineered from zero, including finding out what to build it from that can withstand the conditions. In other words, a long and expensive R&D programme.
"it will be a manageable task to identify and develop the most suitable material."
Yeah - it does sound like a "scoping exercise".
The fast-type reactor, with liquid lead coolant, sounds like it might be relying declassified information on old Soviet submarine reactor designs.
The "liquid fuel" sounds a bit like like the Copenhagen Atomics idea.
It will face the same problems.

This has been reported in the general nuclear press too.
Demonstration reactor to be built in Rwanda : New Nuclear - World Nuclear News
Rwanda signs deal to co-operate on novel reactor - Nuclear Engineering International
I do feel some sympathy for Rwanda after all the crap that has happened there, over the decades. They are desperate for development, and have been quick (maybe too quick) to sign deals with people that might bring some money into the country.
Interestingly, Rwanda does have uranium deposits of its own. I guess it makes a change for an African country with uranium deposits to possibly get some benefit from them, rather than them being siphoned off by some old European colonial country...

It is true that grid stability adds a lot of cost to renewable energy once the non-renewable stuff is not enough to provide that (I mean - it can be done now with a whole load of different storage techniques, but you need a lot of it and it is expensive).
BUT - batteries and esoteric storage techs have been getting better and progress will continue. We have many fallbacks - such as keeping old FF generation available for the once-in-10-years weather goes against you for a long time scenario. And we can have some slice (how much depends) of nuclear.
So:
The point is that there are many different ways to obtain decent supply which is effectively net zero and mostly renewable. Once in 10 years weather-related use of FF is not a problem because it is such a small amount total - and it can at high cost even be net zero if joined to DAC schemes.
It would cost a lot more now than a dirt-cheap (and not allowed on human health grounds in developed countries) dirty coal plant. But we don't know whether it will cost more in 30 years time than advanced coal plants that don't poison cities - even with no requirement to capture carbon. So "bankrupt the global economy" is overreach.
Also, you need to consider intelligent cost-based demand-side management which will not work for everything but is an effective tool in dealing with some of the supply-side variability and allow every EV battery to be an essentially free bit of medium-term grid storage.
The point is that there are many different ways to obtain decent supply which is effectively net zero and mostly renewable.
Yes. Saying you cannot achieve net zero "with renewables only" is true, but it is like saying "you cannot achieve net zero with nuclear power only." That is also true because 100% nuclear power with today's technology would be incredibly expensive and wasteful. Demand for power is greatly reduce at night. You cannot turn off a nuclear power plant for 12 hours a day, so a tremendous amount of energy would be wasted. A nuclear plant has to be used 24 hours a day, most days of the year, or the cost of financing (paying interest) skyrockets. It has to be baseline power. So, 100% nuclear power would be economic insanity. Nukes produce a lot in France, but they sell it to other countries at night.
100% electricity directly from renewables and storage is not possible, because in many parts of the world there is not enough wind or solar, and long distance powerlines are not feasible. You could produce hydrogen or synthetic fuel at places with far more renewable resources that can be locally consumed. You could send that fuel via pipelines or tanker ships. That would cost a lot of money. But, places such as North Dakota with wind, or Nevada with solar, could supply more fuel than the oil from the Middle East.
Offshore wind could produce 18 times more electricity than we now consume, but again the problem is getting the power to the customers in a cost-effective way.
With present day technology, a mix of renewables, storage, natural gas, and nuclear is probably the best way to approach net zero. It is probably the most cost effective. It will not achieve net zero, but it will reduce CO2 emissions and smoke, and it will improve things. Let not the perfect be the enemy of the good.
A slight increase in generator capacity might be needed to replace all gasoline cars with electric vehicles in the U.S. (I do not know about Europe or Japan.) If I have done my arithmetic correctly, only a small increase in generator capacity -- or no increase -- would be needed if most cars are recharged at night. I base that on the LLNL graph, with various estimates I have described here before.

I recommend Solar to car as then no conversion DC-AC-DC is need... You anyway need batteries for solar. China soon will deliver the first mass produced Sodium accumulators. These have more weight but no resource limits! So you can preload accumulators and just echange them.
Only problem:: Law maker urgently must force the once favorite standard for exchange batteries. No more bribes from Tesla etc..
