Thanks for your good wishes, always appreciated.

On involvement of big oil, It wouldn't be the first time big oil has been involved in hydrogen, actually pretty much all hydrogen research in history has been funded by big oil, not to promote hydrogen but the opposite, to knee-cap it in every way possible.

Guaranteed if they are producing it, then it wont be pure hydrogen, it will have deliberate pollutants to keep it arguable about which is worst for the environment, and it will have to be done in a way so as to try to preserve profits, they won't advocate that their business is no longer required, you know?

Hence why all the bolloks about different "colors" of hydrogen - in its purest form, as produced by electrolysis, its just the fundament element H2 and nothing else except a little air and water, "Polluting" it.

On policy approval structures, these are things that probably need to be revised, to accommodate using solar powered Ai to become active in decision making. In short, we have to take the leap of faith, of trusting it, appointing it, to do what we can't trust any human or bunch of humans to do fairly, its a superhuman task by definition.

On where this is most likely to happen first, it's wherever the product of dissatisfaction with government x ease of changing government x technical sophistication of populace is maximum. I would say UK is in a very good position, but so is Germany and the US could obviously do it also. All countries in Europe and the West seem about ready, imho.

It's interesting the current government in UK does see energy is something important, proposing a new publicly owned utilities energy company.

The ideal form of that would be to just issue the money needed to get all kitted up with the equipment needed to start generating mega solar hydrogen on a domestic and community basis. That could be the start of solar indexed stimulus, they just keep issuing it from then on, indexed to the new grand total of solar put to use, assisted by the solar powered Ai. If you look around, you'll see most experts starting to acknowledge Ai will take most of our jobs, making us "Redundant". Why not government, banks, and even the pope included, none are immune, it seems to me.

Rolls Royce is very advanced in hydrogen use, they have worked with all the bigger players in aerospace in UK and Europe, and a few in US, even trialling and testing it in flight. It only requires some adjustments to tanks and engines to make a plane run on hydrogen, most minor in the engines.

The same technology is easily extended to any form of transportation, though it wouldn't impact the established simplicity of EVs much, it would provide an alternative to always expecting to extract more lithium. Traditional garages would quickly become adept at converting old ICE engined vehicles to run on hydrogen.

An ambition of mine is maybe to one day drive something special like an old V16 hydrogen converted Bugatti. I still love the sound of nice ICE Engines with a decent muffler system, why not preserve a few of those old icons, if they are no longer killing both planet and people?

But if it all went fully automatic, which would most suit EVs, relegating manual driving and vehicles to track only, that wouldn't be a bad move either, imho.

On the statement "it takes more energy to process than it's energy produces", yes true, of actually any form of energy production. But look, whatever is produced from solar is something created which subtracts from the total heating effect of using the energy.

In the case of production of hydrogen from solar, 39kWhrs (The higher heating value), per kg is removed from energy which might otherwise be applied to the thermal mass of the planet, regardless of efficiency.

A 2.4 KW domestic scale electrolyser that might be shared between a community of just a few houses can do that every 24 hrs. Imagine billions of those doing that, it's an awful lot of energy removed from heating the planet. There is no way of doing that by any means of energy from the planet, regardless of efficiency.

On how to actually start it, Trump already demonstrated it, but it didn't have the effect of incentivising everyone to max out on solar, because it wasn't announced as solar indexed stimulus, presumably because he/they didn't know at the time.

I would never advocate it's left up to him to do it again, but never say never, if anything he is full of suprises. Would he hand over his job to a solar powered Ai?

Maybe.

Would Kamala, or any of the democrats?

I doubt it. But again we could be surprised.

Here is a more detailed breakdown of why hydrogen is needed for aerospace:
