  • Of course there is an alternative, as the article is arguing implicitly, you ban mining and other unsightly industrial activities in rich areas with strong environmental and safety laws, and outsource it to poor nations without the political leverage to strongly regulate mining companies. This objectively results in far, far more environmental damage, but that environmental damage is contained to highly populated areas full of poor people you don’t have to think about.

    I really wish more environmentalists were pushing for potentially environmentally hazardous processes to be moved to areas with strong regulation and environmental protection laws, instead of just pushing them onto poor people, but unfortunately a lot of people seem to be so (purposely) disconnected from the industrial processes necessary to make everything from wind turbines and trains down to the food that appears on the shelves that they view the mining and manufacturing of these things as completely unconnected to these things themselves appearing in their lives.


  • Typically not for more than a few hours when it comes to in service track, and management actively despises those maintenance windows even when it’s necessary to the continued existence of the track, much less a third party startup.

    There is a reason why even when the entire track and ballest on a main line are wiped out by a natural disaster it will usually be up and running again in a few days.

    As such I would expect any non experimental contracts between the startup and the railway to come with not insignificant financial penalties if they interfere with service, such as requiring a shutdown of the track for repairing the panels being subjected to said harsh environment, thusly either delaying fixing the panels for the next scheduled major maintenance window in a few years or else like most railway inspections doing the work an an active line between trains.

    When the competition is a large open field of dirt that can be accessed at any time for maintenance, can leave the panels up for decades, is centrally located for easy grid access, and requires far less frequent cleaning, I just don’t see how this startup is going to outperform.


  • Don’t forget that maintaining all this means people working directly in the track trying to fix high voltage electrical issues while dodging trains and hoping dispatch doesn’t forget about them, or that ballast(the gravel between the ties) needs to be renewed regularly, much less all the things like realignment and rail grinding that use specialized machinery that needs to go right in the space between the rails.

    This means that those panels are going to have to be removed and installed often, at best vastly increasing wear and tear on them as compared to a fixed installation, and adding the risk that a failure in the pickup/deployment process could scrap a significant number of panels if not caught immediately.

    Or that the hard part of installing solar panels is the wireing, inverting, and grid interconnection, all of which are just made that much harder by having to have electricians doge trains.

    Look, if there really is absolutely no possible available space, like say desert, farmland, roofs, parking lots, yards, fences, well just put the panels up on a simple metal frame over the railway, maybe even integrate the catenary hangers if your feeling daring.

    This at least provides some benefit to running the railway by keeping snow and leaves off the tracks to some extent while also keeping the panels out of the way of running the railroad.






  • Generations? The average American passenger vehicle is 14 years old, so if tomorrow all new cars were electric, you would have haved car transport emissions within 15 years, and be at a 75 percent reduction within the first generation. Cut out fossil fuel subsidies so people are paying the 8 or so dollars per gallon it actually costs for gas and incentivize US manufacturers to actually build affordable cars and you’ll see much quicker adoption that what normal wear and tear causes.

    Of course that isn’t going to happen tomorrow in the US, but you are also going to have a lot of vehicles already sold in the decades prior and which tend to stay on the road longer.

    Compared to the fifteen or so years it takes to build a single light rail line, much less intercity high speed rail, and you are not going to be able to replace half of all car traffic in a single build cycle, much less reach 75 percent within thirty years, by which point you’re trying to replace all traffic in the very small towns and unincorporated areas that even nations renowned the world over for their public transit connectivity often struggle to reach.

    Does the US need to build more mass transit, yes. Can it do so faster than it already buys new cars, no.


  • There are, with the federal government alone paying 7k on most EVs sold in the US. The problem is that they are neoliberal flat subsidies applied at the point of sale that needed Republican support to enter law and as such companies just tack on 7k to the price customers are willing to pay anyway.

    What we need is to incentivize manufacturers to focus on bringing down costs by focusing on things like LFP batteries and smaller vehicles, but manufacturers are currently incentivized to make larger vehicles because people are willing to pay a lot more than the added space cost to make, thusly increasing margins. At the very least making the full subsidy only available on vehicles under 25k, with a decreasing subsidy for vehicles under 50k would probably help, but you would need to be ready and willing to call manufacturers on their near certain attempts to get around it.

    Some actual price wars between manufacturers would help too, but US auto manufacturers will fight tooth and nail to forestall that possibility.


  • The problem is that to effectively fight climate change you need to cut emissions in five to ten years, and not fifty to a hundred, and in a nation where even a solidly blue locality openly dedicated to fighting climate change can take ten years and hundreds of millions of dollars to open a bus lane, it should not come as a surprise that many people with the resources to do so are choosing an imperfect solution now rather than running for office so they can get a bus line to their neighborhood in a few decades.

    This is before we get to the fact that even nations which world leading public transport systems known for connecting to every small village and house still have plenty of cars and highways, people just don’t try and use them to for every trip in a dense city and plenty of people can get by without owning a car at all. We need to eliminate all emissions, not just city emissions, and we needed to do so ten years ago.

    Yes north america needs more common, frequent, and reliable mass transit and the fact that the richest country in the world’s mass transit is in such a state is a national disgrace, but that is not opposed to the quick elimination of oil burning cars but rather should be done in parallel to them.




  • I mean sulfur is also a natural part of our atmosphere that geologic activity has been spewing out into the air for as long as earth has had air, but I’m still going to call it pollution if you’re power plant pumps a vast quantity of it into the atmosphere and now it’s raining acid on me.

    We have more than doubled the amount of carbon dioxide in our atmosphere, with half of that doubling having been done in the last thirty years alone. The very oceans are acidifying to the point large swaths of marine life are being wiped out, and thousands to hundreds of thousands of people are being killled by the effects of global warming each and every year. It’s pollution, it’s just the pollution is on such a vastly larger and more dangerous scale than any acid rain or smog people are used to thinking about.


  • Plenty if you don’t want grid tied, otherwise your local utility probably has an list of the ones they’ll accept somewhere. There is a list of things an inverter will have to be certified to be able to meet for grid tied such as anti-islanding requirements, and in this case i’m afraid you’re almost certainly better off to be going with a reseller the inverter manufacturer actually recommends than playing Amazon roulette.

    From my understanding here it tends to be easier to just stay off the grid for very small systems, either by just plugging in a few panels to a battery and small dc to ac inverter(with appropriately rated fuses between all connections) or else getting an automatic transfer switch and treating the whole thing like a generator.

    That being said RVs and camper vans are a thing here, and there may be some more plug and play systems in that direction but small 12v systems are a bit out of my wheelhouse.
