There isn’t any limit to growth, if we remove our dependence from rare Earth elements, and diminishing Earth energy.
By Earth energy I mean the Joules of energy stored on Earth in all the ways it is stored, in matter of all kinds, and even in wind, waves, and the rotation of the planet.
Almost all of our human activity has subtracted from that to date, until now, when we are finally going solar powered.
The work we do with solar energy, adds to the Energy of Earth, instead of subtracting from it.
Isn’t it interesting that hydrogen generated by electrolysis from solar electric, stands as a valuable fuel which functionally replaces fossil fuels, with none of the pollution, and even burns whilst producing nothing but breathable air, and drinkable water?
Further, that the process is completely reversible, functionally replacing batteries, with no requirements for rare Earth elements?
And that large area solar collection farms on Earth, in theory act positively towards the rotation of Earth, in same way as the natural sun absorbing biomass on Earth, instead of like a brake, as seems to be happening with the removal of Biomass? (Check out the history of leap seconds)
And finally, the effects of this on economy (Your subject?)
The increasing amounts of solar energy being put to use on Earth, are valuable product, donated from an external donor, whether they are used to create hydrogen fuel, create pow tokens like Bitcoin, or just heat a water tank on a roof, they are valuable all the same, and should be reflected by the issue of free money honestly reflecting them, by the principals of Austrian economics, valuable product added, should be reflected by the issue of money needed to purchase it.
Do this, and the value of the currency it is done with, is maximised in markets, surely.
The age of fixed money supply being used to represent actual physical commodity supply, are at an end, it seems to me.
