I wonder what sort of problems having near-unlimited energy at our disposal would bring. Like, light and noise pollution are already bad enough. But would people be even more careless with that? And if we manage to automate most things and energy isn’t an issue, how would we live and occupy ourselves? How would that change industries and the world? How would that change things like war and power struggles in general? What about science and electronics?
It’s a bit concerning but also fascinating
Thinking of the hypothetical scenario where in a short timeframe energy would become near unlimited and almost free:
On the positive side: with no energy limitations, Direct Air Capture technology could be scaled massively. That’s one really promising technology that can take carbon off the air and use it for other things (like sustainable air fuels) or removing it altogether.
Also this would accelerate the transition to electric cars and well, electric everything: why pay for fuel for your car, your stove or boiler, when they can be almost free? That has a potential for good effects on the environment too.
On the negative side: this opens the door for more, cheap transport. If people don’t have to pay for fuel, they’d be more willing to take the car everywhere. This would mean more roads, more infrastructure, more destruction of ecosystems, less space for pedestrians… A trend that is already too difficult to reverse in a world of expensive fuels.
In terms of economics, I could see this accelerating the gap between countries. Those who could benefit from semi-free energy first would have an immense competitive advantage and also lower their manufacturing costs, leaving worse-off countries in a position where they can’t compete because of technology nor because of cheap labour.
Honestly, we won’t likely see cheap energy in our lifetimes. A fusion powerplant could come online that is able to power the entire eastern seaboard of the US with some leftover for millionths of a cent per kW and we would still be getting charged just as much if not more for it. The general populace will never see the benefits of nearly infinite, nearly free power because the company that owns it will just see it as a higher profit margin. Sure, they may underbid fossil fuels or other renewables by just enough that they can’t operate, but it will still be orders of magnitude more than we should be charged. The only way the population sees the benefit is if the reactor is publicly owned and the government is prevented from converting it over to privatization because that has ever gone well for us.
I agree with you, prices will still be market driven. However I was replying to a comment about a hypothetical scenario, which I think is useful to explore however unlikely it might be.
We live in a post-scarcity world - yet people are still starving ans stilll dying from easy curable diseases.
I won’t be holding my breath.
Yup. The rich will use it to consolidate power and wealth, while the poor still have to go to work and grind for 50+ hours a week just to scrape by. Nothing will change, because the issue isn’t a lack of resources; The issue is resource distribution.
I can tell you, unequivocally, without a doubt, light and noise pollution are much better than energy shortages.
Yeah, I meant more along the lines of what those unknown problems could look like. For example, whales get very disturbed by sound pollution in the water and I can just imagine that a lot of other animals do as well. Not to mention that we ourselves apparently risk mental health from all the noise in the city. How would that change if we have more electronics at our disposal? Or maybe it’ll be the opposite and we can build more quiet EVs.
I’m just over here waiting to hear that the USAF has had fusion in the form of bombs for a decade but let us all keep struggling.
Yeah, why didn’t they provide hydrogen bombs for everyone?
Mmmmm my own personal demon core… :)
Unlimited for our current needs or on a planetary scale, but nowhere near enough at the scale of a solar system of galaxy. I doubt it would be enough energy to for example open a wormhole or accelerate a spaceship to even 1/3 of light-speed. Not only is the amount important, but also the ability to sustain the output.
We’ll just be on the first rung of the Kardashev scale. Of 3. However, the jumps between the rungs are huge (logarithmic). Complete control of planet, star, galaxy.

“Near limitless energy”. …
OK what are the limits? Preferably absurd answers please…
They boiled 10 kettles of water with this energy.
Ultimately, if everything is optimized, its probably only limited by the number of kettles available.
Limitless only for the same visit. 1 customer per reaction.
No repeat visits or sharing allowed!Since everyone else gave a joke answer I’ll take a stab in the dark and say the upper limits would be the availability of hydrogen and physical limitations in transforming heat output into electricity. The hydrogen is the most common element but 96% of it is currently produced from fossil fuels. After that, it would be how well you can scale up turbines to efficiently convert heat to electricity.
If you have fusion energy, creating H2 from water via electrolysis is a joke. You can do it at home. It only requires a lot of energy. But with energy from fusion it will become super easy, barely an inconvenient
Well. Assuming the cost of splitting water is lower than the energy produced from the same amount of hydrogen.
It is muuuuuuuuuuch lower. The actual energy is incomparable, like an ant vs superman level of energy.
The energy in practice it’ll be extracted from H2 has to be much higher for the process to have a practical use
In the news, 5.000 years later : “Scientists warned that our mass extraction of hydrogen may produce global salinization, but no one wants to reduce its energy consumption.”
Electrolysis has up to 70% efficiency and needs sulfuric acid. The superheated thing has about 90% efficiency.
You know how the sun radiates an incredible amount of power through millions and millions of tonnes of material undergoing nuclear fusion every minute, and the sun is expected to last for millions of years?
Well, not that much. But it’s still a lot!
You would have enough power to play a game of Civ II to completion.
One limit less.
2 energies and no more
The limits are only your imagination.
The flamingo population must remain constant for ignition to function.
It’s near limitless in the sense that the fuel for it will not run out. … But to be honest, the ‘unlimited energy’ thing is mostly marketing hype. If we were worried about fuel running out, then solar would be the obvious go-to. That’s even less likely to run out than fusion power, and it has the advantage that we can already build it. And fusion, like solar and everything else, still requires land and resources to build the power plants. There are hopes that fusion power plants might be be more space efficient or something, but that obviously isn’t the case currently. Currently the situation is that people have been working on this for generations and the big breakthrough is that we can now momentarily break-even with power on a small scale with state of the art equipment. So I think it’s a bit too soon to claim it will have any advantages over solar. Right now it is not viable at all, and any future advantages are just speculation.
That said, fusion power is technology worth pursuing. It’s not complete garbage green-washing (unlike “carbon capture and storage”, which really is complete garbage), but the idea that fusion it’s some holy-grail of unlimited power is … well … basically just good marketing to keep the research funds flowing.

Ah, my childhood ISP is still luring around.
“ Scientists in California shooting nearly 200 lasers at a cylinder holding a fuel capsule the size of a peppercorn have taken another step in the quest for fusion energy, which, if mastered, could provide the world with a near-limitless source of clean power. Last year on a December morning, scientists at the National Ignition Facility at the Lawrence Livermore National Laboratory in California (LLNL) managed, in a world first, to produce a nuclear fusion reaction that released more energy than it used, in a process called “ignition.” Now they say they have successfully replicated ignition at least three times this year, according to a December report from the LLNL. This marks another significant step in what could one day be an important solution to the global climate crisis, driven primarily by the burning of fossil fuels. For decades, scientists have attempted to harness fusion energy, essentially recreating the power of the sun on Earth.
After making their historic net energy gain last year, the next important step was to prove the process could be replicated.
Brian Appelbe, a research fellow from the Centre for Inertial Fusion Studies at Imperial College London, said the ability to replicate demonstrates the “robustness” of the process, showing it can be achieved even when conditions such as the laser or fuel pellet are varied.
Each experiment also offers an opportunity to study the physics of ignition in detail, Appelbe told CNN. “This provides valuable information to the scientists in addressing the next challenge to be overcome: how to maximize the energy that can be obtained.”
Unlike nuclear fission — the process used in the world’s nuclear plants today, which is generated by the division of atoms — nuclear fusion leaves no legacy of long-lived radioactive waste. As the climate crisis accelerates, and the urgency of ditching planet-heating fossil fuels increases, the prospect of an abundant source of safe, clean energy is tantalizing. Nuclear fusion, the reaction that powers the sun and other stars, involves smashing two or more atoms together to form a denser one, in a process that releases huge amounts of energy.
There are different ways of creating energy from fusion, but at NIF, scientists fire an array of nearly 200 lasers at a pellet of hydrogen fuel inside a diamond capsule the size of a peppercorn, itself inside a gold cylinder. The lasers heat up the cylinder’s outside, creating a series of very fast explosions, generating large amounts of energy collected as heat.
The energy produced in December 2022 was small — it took around 2 megajoules to power the reaction, which released a total of 3.15 megajoules, enough to boil around 10 kettles of water. But it was sufficient to make it a successful ignition and to prove that laser fusion could create energy.
Since then, the scientists have done it several more times. On July 30, the NIF laser delivered a little over 2 megajoules to the target, which resulted in 3.88 megajoules of energy — their highest yield achieved to date, according to the report. Two subsequent experiments in October also delivered net gains. “These results demonstrated NIF’s ability to consistently produce fusion energy at multi-megajoule levels,” the report said.
There is still a very long way to go, however, until nuclear fusion reaches the scale needed to power electric grids and heating systems. The focus now is on building on the progress made and figuring out how to dramatically scale up fusion projects and significantly bring down costs.
At the COP28 climate summit in Dubai, US climate envoy John Kerry launched an international engagement plan involving more than 30 countries with the aim of boosting nuclear fusion to help tackle the climate crisis.
“There is potential in fusion to revolutionize our world, and to change all of the options that are in front of us, and provide the world with abundant and clean energy without the harmful emissions of traditional energy sources,” Kerry told the climate gathering. In December, the US Department of Energy announced a $42 million investment in a program bringing together multiple institutions, including LLNL, to establish “hubs” focused on advancing fusion. “Harnessing fusion energy is one of the greatest scientific and technological challenges of the 21st Century,” said US Secretary of Energy Jennifer Granholm in a statement. “We now have the confidence that it’s not only possible, but probable, that fusion energy can be a reality.”

I thought the Z machine at Sandia produced more than it consumed? That was like 20 years ago
