We do, but its for freight because passenger trains in the US are dumb outside of light rail. The US is not Western Europe.

I disagree, the USA is ideal to be mainly based around train infrastructure for people. I would argue the USA has far better conditions to be mainly train based, than western Europe does.

The size means that it takes incredibly long to travel by car. Trains can be much faster, and are much less of a waste of time. You can literally do anything else when riding a train. If you want to travel long distances without a plane, you could spend several days in a car, doing nothing else but focussing on driving. Or you could travel in a train for a day, in which time you could do anything you wanted.

If you want to see an example of how well trains work in a large country, look at China.

Chinas average train trip is 300km in Germany its 30km, people in Europe are not taking trains from Lisbon to Moscow which is the same distance as LA to NY (4500 km). Western Europe and China don't have to move freight from one coast to another like we do in the US. So either we build an entire second set of rail lines and then hope people would rather sit in a train for extend periods of time (which they won't) versus just flying or we agree that the price of all goods will need to go up because we will prioritize passenger service on rail which means we need to drastically change the safety standards (as example freight trains in Europe can't be over 700m so they can stop fast while in the US 3000m is normal) and hope people will want to sit in a train all day (which they won't). The funny thing is that people on Reddit think they know better then all the people in the US who work in transportation, how fucking arrogant can people be? Europe and China can prioritize passenger service because the don't need the rail for freight due to single coasts, they use water and small trucks to transport goods, the US can't do that.

BTW I like trains but the distances are to great and even in China there are not typical routes that are like San Fran/LA to NYC/Washington DC. Beijing to Hong Kong is only 2000km, half the distance.

bowsmountainer t1_j0el8hs wrote

Let's make something very clear. At the moment, if you want to travel thousands of km, the best option is planes. If you want to travel tens to hundreds of km, the best option is trains. I'm not saying that All travel from LA to NY has to be via train. I'm not saying that every single journey, no matter how long should be via train. But it is ridiculous how hard it is to travel from e.g. Chicago to NY, which is a journey that should definitely be easily possible by train, but isn't.

And no, this isn't because of freight (which, other countries have too!). The reason the train infrastructure in most of North America (because Canada is just as guilty) is so bad, is because of the car industry. They tried their very best to hinder trains at every turn. they demolished trains, and paid politicians to ensure trains would be defunded, in favour of cars. You can see the result very clearly. They made countless billions by forcing everyone to drive a car, rather than the obvious best option of using trains. There are fewer trains lines now than there were 100 years ago. Just think about how ridiculous that is.

Trains are far more efficient in terms of energy, time, how many people need to focus on driving, space required etc. They are also far safer, and don't destroy the environment.

Yes, the USA needs more rail lines. But even without new rail lines, notice that rails are not used most of the time. The temporal separation of subsequent trains is often many hours in the US. Just think of how many more trains you can fit on the same line. And compare that to how roads are used all the time, not just once briefly every few hours.

You want to talk freight? Sure. Consider how many drivers are needed to drive trucks across the country. Now consider how many train drivers would be needed instead to deliver the same freight. Also consider that trains can go much faster than trucks., are much more efficient. Sure, you might need trucks for the final few km. But apart from that, trains are obviously the best answer for delivery.

You brought up the topic of safety. Yes, trains can't stop easily. But trucks can't stop easily either. Look at the statistics of how many people are killed by cars each year. Now look up how many people are killed by trains each year. Trains are orders of magnitude safer. It's not even hard to see why. Trains are on tracks. Cars aren't. Trains have a single driver. Every car has their own driver. People drive trains for work. People drive cars because they have to. Trains are self driving. Cars aren't. Trains have existing infrastructure to keep people away from where they drive. Cars don't.

It’s far cheaper to build trains, than to continue massively subsidizing the car industry, and maintaining car based infrastructure.

You might have used perpetual motion to avoid the interjection but its not a fair comparison. The math says perpetual motion will always remain energy neutral. On the flip side, the math says fusion yields an energy positive.

SecurelyObscure t1_j09gtnq wrote

I wasn't comparing the feasibility of fusion vs perpetual motion. I was using the wasted time and effort put into researching something to demonstrate why it's not a reasonable to compare r&d costs to the amount of money spent on obtaining a known energy source.

Billions are spent on all sorts of energy research. Solar, hydro, chemical, biological. The overwhelming majority will go nowhere. Some end up being outright scams, like perpetual motion devices. Picking one that might eventually work and saying "God we're dumb for not doing this instead of using oil" is like saying people are dumb for having bought stocks other than Amazon in the 90s.

Or are you going to tell me how actually stocks are a financial entity so it's not a fair comparison to energy.

ahxes t1_j0a7br8 wrote

I actually think thats a pretty apt comparison.

Given the hindsight, I think every person who bought stocks in the 90’s wishes they bought Amazon instead.

Just like the people on this post wish that more resources went into fusion research.

Hindsight is important. We need to be able to admit that things need to change and wish that we found the right path first. We also need to acknowledge the path in the first place. We needed fossil fuels to get where we are, but if more money went into green energy research earlier we would be years ahead of where we are now and maybe a lot of the problems we are facing today wouldn’t be as big to overcome.

IMO: R&D is not a waste of time or money when the pay out is a solution to the energy crisis.

I doubt it, to get Fusion to work other technologies need to be in place and some of the things they will need don't yet exist. Even Ernest Lawrence, the father of "Big Science", understood that.

It's probably not the kind of market where private companies thrives, the capital needed and the initial risks will probably be high enough that a few failures would bankrupt most companies. On top of that fusion generation is stable, reliable and predictable, unlike fossil fuel power plants there is not much speculation, so the profit margins will be pretty slim (especially since electric grid are often somewhat nationalized, or at least the government has a strong influence). Lastly ITER is a collaboration between countries, the agreement is that when ITER will archive its goal the results will be shared between the participants, no company will be able to archive a monopoly.

I'm pretty sure if we don't change our system drastically until it's viable, it's gonna be the same as with nuclear: Public funding for research, lots of government projects, private corporations then build power plants which are largely government funded, the energy gets heavily subsidized in the market and then people are told it's the cheapest form of energy and everyone talks about how the private sector is so much more efficient because the government would not have been able to turn a profit.

Surely so also does research into emission reduction. And surely the cost of zero carbon is far less than the cost of not reaching zero carbon.

Higher energy density per mass, but much much lower energy density per volume, which really matters if you're building a vehicle. There's only so much room inside an airplane for fuel tanks.

https://en.wikipedia.org/wiki/Energy_density#/media/File:Energy_density.svg

But regardless, whether it's gasoline or hydrogen, the point is that with enough free energy you can synthesize any fuel you need.

1

ignigenaquintus t1_j07ieex wrote

Well yes, but with a specific energy about three times the one of gasoline and a specific density of about 1/4 of gasoline the reduction in energy per unit of volume isn’t so massive and the benefits on the reduction of negative externalities is very very significant. Please correct me if I am wrong but in theory we would need deposits that are 33% bigger in volume, correct?, the problem is the temperature necessary to keep it liquid of course. And as important volume is, weight may be an even bigger factor for some transport systems, like airplanes.

In any case the point, as you mention, is that with more and cheaper energy we could sintetice the fuel.

Hydrogen infrastructure and production is also quite difficult and expensive, but it has enough intrinsic benefits to make it a worthwhile struggle. Fusion will be similar.

There's really no comparison. Fusion reactors have to withstand 100x the heat and 1,000,000x the neutron Flux as fission reactors. No materials exist which can actually withstand that and there's no clear path forward given the laws of physics. Fission is actually laughably easy. You literally just put enough uranium together in the right geometry and it gets hot. I could make a fission reactor in my basement if you gave me some enriched uranium to fuel it.

jrkib8 t1_j07wsg6 wrote

There are literally actively used methods for material confinement. Most common are magnetic confinements like tokamak and Stellarator reactors. New methods using beryllium blankets by ITER are shown to be effective. Their two problems are they currently need to be actively cooled which eats away at the energy input/output ratio and they contain natural amounts of Uranium, some of which is U-234 and radioactive requiring hazardous disposal at their end of life. Not as serious as.apent nuclear material disposal from fission reactors, but still a major drawback.

There are also companies with successful experiments fusing deuterium and H-3 in lieu of tritium as tritium is costly to produce. Allegedly, this method doesn't require confinement. Since the products are ionized, it actually uses the reactive expansion to power magnetic generators in lieu of heating steam turbines.

But the NIF that just released their announcement doesn't even use magnetic confinements, rather an inertial confinement (ICF) reactor. This means the confinement times can be improved linearly with density of the fuel and it only requires about 10% of the mass of the fuel to reach temperature sufficient for plasma, which also allows for longer reactions. ICF research is way more immature than MCF so it has always been assumed that MCF would be the breakthrough. That's what makes this such an event is that ICF beat MCF to the finish line creating more energy output than input.

Lastly, they didn't just have an experiment with miniscule energy that could only be detected with instruments. They created 3.15 mega joules. That's 875 watt hours. That's enough to power a TV for a day and well beyond enough to prove their confinement technology works

That 300 MJ was to start the reaction, you don't need to continually pump in 300 MJ. Scaling this up by like 1000x and you surpass that one time input. And the scale would likely need to be far higher for commercialization.

Nobody is saying we're there yet, but to deny how remarkable this breakthrough is, is pretty short sighted. It doesn't mean we decommission any existing fission reactors or even stop planning their construction. It does mean that if $38 billion can produce a net positive (and yes this proved net positive by all practical definitions) reaction, any government subsidies or research into hydrocarbon derived fuel needs to be phased out. That's $20 billion annually for oil alone in the US. God knows how much towards corn for ethanol. This announcement justifies a substantial amount of that phased out and put towards fusion.

Yesterday, the U.S. Department of Energy announced that US scientists for the first time successfully produced more energy from a nuclear fusion experiment than the laser energy used to power it. This is a major scientific breakthrough that will lead to a new source of clean, carbon zero energy. This achievement is the result of decades of hard work from scientists all over the world and several billions of dollars. The U.S. government has been funding fusion energy programs since 1954, enacting hundreds of millions of dollars every year to reach a goal of net zero energy. This chart follows the year over year funding from the U.S. government to fusion energy programs, along with the contributions made to the international nuclear fusion research and engineering megaproject (ITER).

It has taken 68 years and $18.8 billion ($35.8 billion when adjusted for inflation) to reach this historic milestone that will be sure to change the world as we know it.

That's a pretty damn speculative argument passed off as fact. We are still nowhere close to an actual power plant. It's also wildly immaculate to imply the experiment in question produce more energy than it consumed because in reality it consumed 100x as much as it produced.

Ya OP didn't word that well. IIRC the laser put around 2MJ on target and the resulting fusion yield about 3MJ, so if NIFs laser was more efficient than what OP said would be accurate. But in actuality it took the NIF laser something like 200-300MJ for that shot. But when you consider that NIF is getting relatively old and that it's a research center so efficency wasn't at the forefront of design it's not unreasonable to see where this could hopefully lead.

Your lasers would need to be 100x as efficient and your reaction 100x more powerful to be a useful energy return..

But is that impossible, I don't think so. I'm not going to say we're 10 years away from it being viable because we've been 10 years away for the past 50 years. But look at how fast every other technology evolves, this is literally the beginning for where it all starts coming together. I'd bet people alive today will see fusion energy become a reality.

See, that right there is the fundamental error all of you guys are making. That's not how progress works at all. Most of the time progress is painstakingly slow and its actually slower now than almost any time since the start of the industrial revolution. When a new technological front opens up you do indeed get rapid progress, but after 15 years or so progress slows to a crawl again. At the rate fusion research is going it will take 100+ years to actually reach a point it could reach a real net gain end to end. And even if it does so what? The cost in terms of steel, concrete, etc is going to be astronomically high regardless.

I an amazed, 2021 nasa budget if the internet doesn't lie to me was 25b

Imho the money spent in both space and fusion is worthy but this gives an idea of how little is 35b adjusted for inflation spent in fusion spanning 68 years compared to another endeavours

one wonders what fusion would achieve if they did a Manhattan project of it or sacrifice money as they did like at the beginning of the space exploration and moon landings

Carbon neutral is a very difficult word. Think of, for example, how much concrete you need for nuclear plants, and presumably for fusion plants too, once we have them.

Now that government has done the heavy lifting, it's now time for private industry to step forward and take the technology and take credit. As has been done so many times in the past.

Seems like a lot of money. We went to an Asian Fusion last night and spent less than $100.

Honestly if you told me it was gonna take 200 years to figure out, I’d still probably say it’s worth it from a long term planning perspective.

So you can either buy a social media platform to destroy, or you can subsidise many decades of research into an amazing new, clean energy source, and still have billions left. What a difficult choice!

Is this supposed to be a joke? This is couch cushion money compared to corporate subsidies and the defense budget. For an important long term investment that will pay off infinitely when it’s figured out

Oy. $35 billion. imagine that had been invested in solar research.

Now imagine it in the context of the Keystone pipeline leak in Kansas this week. In the context of the sabotage on the NordStream gas pipeline. In the context of the power grid issues in Texas in a successive winter and summer. In the context of the grid sabotage in N.Carolina last week, and of suspected sabotage attempts elsewhere in this nation over the past couple weeks. In the context of Russia destroying Ukraine’s power infrastructure.

Fusion remains decades out from a practical perspective, and is not local. You’re not gonna have a fusion reactor on your roof.

On the other hand, you could be collecting and storing the energy created by the fusion reactor called the Sun.

I would be incredibly surprised if solar research has received less than $35 billion over the last 70 years. Maybe fusion wouldn’t be decades from being practical if it had been given more funding than a handful of aircraft carriers or three quarters of a social media company.

Dude, there's been probably almost a trillion dollars spent on solar at this point.... Costs have barely been reduced in the last decade, when most of the money has been spent. Not to mention hardly applicable to half the world's climate.

If all of Europe had stuck with nuclear power they'd be energy independent right now. The $585 billion Germany spent on solar and wind infrastructure coulda been spent updating their nuclear plants, and Putin would have next to no chips to play with. You have your priorities mixed up.

NREL budget 2020: approximately $500 million, up from $372 million three years earlier.

So no, the federal investment in renewables research has been negligible compared to virtually every other energy technology. Almost all the research has been privately funded.

Well, yeah, that's by design. What incentive does the government have to spend money on renewables? They can just make policies that incentivize everybody else to do it.

"Big Energy" is down with renewables because they are unreliable enough that the whole grid needs to be backed by oil and gas to 100% capacity. The high principle investment and parts/ repair turnover along with the plentiful eco-contracts to go around make for reliable revenue streams. Energy industry gets to have their cake and eat it too.

You know what doesn't make alot of revenue? Nuclear power. Because it's like 100-1000x more efficient than oil, gas or renewables. My point is if government didn't fund nuclear research nobody would, it's too cheap. Lots of people are willing to fund renewables because it makes them money.
