Hydrogen is the only way aerospace will stay airborne, after fossil fuels use has ended. Might seem a long way away now, but everything changes, when we start to issue money reflecting economic product created from solar energy.
Then you start to look at what looks like all the negatives of hydrogen in a positive light, so as to speak. The water consumption of it can be taken andvantage of by noticing that the end result on water, of it going through firstly conversion to hydrogen, then de-conversion, back to water at the point of energy consumption, often mobile, is filtration and distribution of drinking water. So what looked at first like a disadvantage of hydrogen suddenly starts to look like a god sign, this is what we were supposed to do, its a sign given to us by nature, the way I see it.
Another of these is by noticing hydrogen is the input energy component of "Solein". So not only can it functionally replace fossil fuels useful to all machines, but it can also be used to support and complement the human food chain, reducing our burden on nature, allowing the latter to recover a little.
And there is a whole new plastics technology we can establish, built on hydrogen, just like fossil fuels, we will quickly read across the techniques used on fossil fuels to hydrogen.
The final message is got by noticing that what we put to use, into storage from solar energy, is energy subtracted from what would become heat from the sun, if neither we nor nature used it, and look, we already removed a large part of nature using it, this is the first driver of temperature, before we consider the multiplier symptoms like CO2. I summarised this in an Amazon book, "The Energy Polarity Multiplier Framework", working with ChatGPT, it seems to have this all worked out already, it is itself resident on solar energy, which is mathematically positive, rather than mathematically negative energy by extraction.
So the energy efficiency of solar hydrogen is positive, relative to the energy efficiency of any extracted energy chain, 20 or thirty percent efficiency in the hydrogen chain means 20 or thirty percent of the energy processed goes to things other than heating the planet, whereas even at 90 percent efficiency in an extracted energy chain, we still dont account in terms of planetary temperature for the energy lost in refinement of the materials processed to extract the energy, and the energy yielded, is a measure of a negative quantity, its a measure of how efficiently we can destroy, pushing up the temperature, rather than how efficiently we can create, pushing down the temperature.
See the difference?
The money-fuel tree story I wrote explains how that works, and the Kardashev Hinge story explains why its servers have to be in that architecture.
The only way to get enough solar real estate to produce enough hydrogen to functionally replace fossil fuels for all applications including aerospace, is to do the creation of it on a domestic and community level, ie a platform is a community, a business is a community, a government is a community, an airpoirt is a community, etc, which means probably losing most of the conventional grid architecture.
This is because the sun is distributed by nature, we can't get around that.
The reason I think we will be forced to a solar indexed money issuance system much sooner than most of us realise is because of a couple of studies, this is one:
