First, on the energy side—you’re saying my vision hinges on fusion happening fast enough to fuel it all.
It doesn’t.
Fusion would be incredible, yes, but it’s
not necessary for the future I'm describing. Solar alone could scale massively without it.
Look at it this way:
Today,
the payback time for a solar panel meaning the time it takes for the panel to generate as much energy as it took to make it—is down to around
one to two years, depending on the model and location. Panels can last 25–30 years. That’s 20+ years of surplus clean energy per panel after you pay back the manufacturing cost.
What that means is that in principle, every panel generates enough "excess energy" to manufacture several more panels over its lifetime.
You get exponential growth without needing fusion.
Start with one panel. It pays back its energy cost in two years, then its surplus energy can be used to make two new panels in the next few years. Those two pay themselves back, then create four. Then eight. Then sixteen.
Exponential expansion.
And that’s just terrestrial panels. Add orbital solar in space (already being researched seriously by Japan, China, the US) and the growth potential becomes almost unlimited because space-based solar isn’t bound by night/day cycles or clouds.
Those are truly giant levels of investment that you propose there. And at the end of it, the electricity produced is so in excess of demands as to be virtually worthless?
If I represent a multinational insurance company that typically invests in very long term infrastructure projects to pay back over the course of decades, how do you sell me the bonds that will fund your investment? Pitch me that deal.
That's one detail.
Alright, here’s the straight answer—because that’s a good and important challenge you’re putting on the table.
First:
yes, at first glance, exponential solar buildout sounds like it would crash energy prices to near zero, making investment unattractive.
If the system stays structured purely around profit-seeking private players, you’re absolutely right: the business case falls apart once marginal cost collapses.
But that points directly to
why the future I’m describing can’t just be left to corporations alone.
One real solution—one that actually respects the physics and economics here—is that
we as people could demand that our governments capture free sunlight on our behalf.
Governments could, and should, move to
treat sunlight as a public good, just like water rights or public airwaves.
Instead of handing the skies over to greedy corporations whose only motive is to exploit scarcity for profit, we could insist that solar infrastructure becomes part of
national or regional public assets.
It’s not some radical left-field idea, either. We already do this with things like roads, public education, even national parks.
We build things not because they yield perfect corporate profits, but because they serve the survival, stability, and progress of society as a whole.
In practical terms, how do you pitch it?
Not by selling it like a profit engine.
You pitch it like
insurance against existential risks.
You go to that multinational insurance company and say:
- Energy independence at national scale
- Climate risk dramatically reduced
- Blackout risks minimized by decentralized generation
- Economic resilience when fossil fuels fluctuate or collapse
- Strategic security against resource wars and foreign energy dependency
- A population stabilized by abundant cheap energy—lowering social unrest risks
In other words: you're not selling them just a product, you're selling them
civilization insurance.
And let's be clear: insurers already think this way.
They’re some of the loudest voices calling for climate adaptation investment because they know—mathematically—that the cost of inaction will dwarf the cost of early, aggressive infrastructure spending.
If we treat solar infrastructure like a
strategic reserve, not like a quick-buck commodity, then governments (backed by long-term bond issuance, sovereign wealth funds, or public-private partnerships) could build solar at massive scale without needing the old ROI models based on artificial scarcity.
In fact, several countries are already starting down this path.
China’s government is building state-owned solar farms on scales the private market would never have dared.
Spain, Portugal, even India are talking about government-facilitated solar grids that aren't just for profit—they’re for survival.
So:
Yes, it’s a colossal investment.
No, it's not attractive under "business as usual" capitalism.
But, if we shift the framework—treat sunlight as the new commons—then it’s absolutely feasible, and absolutely necessary.
Because if we don’t, the corporations
will move in, monopolize solar access, and turn free sunlight into a metered, pay-per-watt service that makes today’s monopolies look quaint.
And then the future we’re fighting for is already lost before we even get there.
You want a serious world that survives the collapse of labor economics?
You start by making sure the energy that could sustain it doesn’t get captured by the same interests that profited from our exhaustion in the first place.
