  1. It's not the "only real important question". If the savings are larger than the cost of the rotor sails it makes sense to put them on ships even if the effect weren't huge.

  2. They said it's $400 per day which would come to about $146,000 per year. If we assume that the shipping company expects a 10% return on investments these sails could cost $1,460,000 and still make financial sense. Of course, there are complications because the sails don't last forever, because there probably are some maintenance costs, and because ships don't sail every single day of the year. On the other hand, these things probably don't cost quite that much.

  3. "I rather be stuck in traffic then having to worry about being robbed at night." What? A street is going to rob you (whereas a highway isn't)? That's a total non-sequitur.

  6. Which means that cars are even worse in NYC than in Helsinki.

  7. "Instead of highways people will use inner roads, thus increasing congestion." The highways are going to be replaced by streets with housing along them. The people living in those places are then already inside the city instead of needing to drive in from outside which reduces congestion.

  8. The highways don't go to the center anyway.

  9.  @manuhonkanen2111  I'm not sure that's relevant. The first of these highway removals started earlier this year (2021). It's removing something like 1 km section of highway in Laajasalo. Surely no one uses that to get to the center? It's not even on the same peninsula as the center. Secondly, if some people who don't live close to the center insist on doing their shopping by car, I think it's better for everyone if they go to a supermarket rather than come to clog the streets in the center.

  10. Now this year (2021) the first one of these (in Laajasalo) is under construction.

  11. Cars still take too much space in cities.

  12. "Finland’s most lucrative export is petroleum" That's not even remotely true. Petroleum means crude oil and Finland has none of that.

  13. Cars take too much space to be an economical option inside a city.
    2
  14. "Finland is the wrong place to talk about less freeways" It's not. Land inside Helsinki is expensive. Highways are not an efficient use of that land. It makes sense to replace it with housing since there's a lot of demand for it.

  15. That's probably not greenhouse emissions but some kind other of emission (like sulfates).

  16.  @Helsinkisillest  Hyperloop is almost certain to not be viable. Even if it were, it wouldn't for these types of commutes but rather for travelling between major cities like high-speed rail or airplanes are used today.

  17.  @josephstewart98 : "However, when batteries are sufficiently improved, there may be the possibility of storing wind energy and therefore making it the primary source of propulsion." But that's not how the rotor sails work. They don't generate electricity but, in fact, expend energy since they need to be spun by a motor so you can't really store the propulsion they create anywhere.
    2
  18. "cars drive more efficiently whilst driving on a motorway (freeway) compared to regular roads" But it still doesn't make economical sense inside a city. You can't put a lot of housing along a highway but you can do it along a street. Now these people are already inside the city instead of needing to drive into it from outside. That's even more efficient than driving along a highway.
    2
  19.  @gamesman0118  "would dissuade most from having one..." Well, then there's no need for these highways inside the city.
    2
  20.  @gamesman0118  Through the streets? It's not like highways reach every nook and cranny of the city but still the shops and stores that are not along highways are able to restock. I see no reason to expect that removing short sections of the highways inside the city would be a major hurdle in this respect.
    2
  21.  @gamesman0118  I don't have a problem with highways between cities but inside cities they're not an efficient use of limited space. The first one of these removals started this year and it remover a roughly 1 km long section of one highway.

  22.  @muronjunat1826  That's not what they're doing. There's still going to be a highway connecting Tampere and Helsinki. It just won't extend as far inside the city.

  23.  @mikrokupu  "I pay EUR 380/month + 18K deposit." How's that deposit possible? By law the deposit cannot be more than 3 months' rent, i.e. 1140 € in this case.

  24. "Unfortunate for people in the auto industry in Helsinki." Why would we need to favor them over others?

  26. "Most freeways are used by people that come Helsinki to work. And then go home again." Instead of this it's more efficient to use the land for housing (and a street) so more people can live inside the city instead of needing to drive into it from outside.

  27. I'd imagine that they would use an electric engine rather than a diesel engine to spin them.

  34.  @heist3197  "finland has small population so it could work" It's the opposite. The higher the population (in a given area) the less sense cars make.

  35.  @suokkos  Tunneling is expensive. For the most part the benefits are not worth the cost (except maybe in a few specific locations).

  36. "Those tolls will generate money and that's about it." Are you claiming that they don't reduce traffic?

  38. "Tearing down freeways will just move people [...] to neighbouring cities." This part makes no sense. Tearing them down makes room for more housing and based on the price of housing in Helsinki there is enough demand that that housing is going to be occupied. That means (in the net) more people moving into Helsinki, not out.

  39. Then they just have to use the propellers. To my knowledge, even on windy days these only provide a portion of the thurst and you still need the propellers as well. The benefit is merely reduced fuel consumption.

  40. There's no congestion charge...

  41. "harder for Builders getting to work" It's the opposite since housing is going to be built where the highways were.

  42.  @jaelynn7575  "I don't think you understand what "going on strike" means! No need for authorization, you just all have to choose to do it to bring attention to the problem." When the air traffic controllers went on a strike during Reagan they (all the striking ones) were fired. Reagan also banned the federal government from hiring them again.

  43.  @LS-ys8nr  Railway Labor Act regulates the right to strike.

  45. LA being bigger than Helsinki means there's more reason to remove highways there.

  47. Additionally, a rotor sail would be much larger relative to a car than relative to a ship (even if the ones on cars were smaller in absolute terms). In very strong winds they might risk tipping the car over. They might also prevent them from going under many bridges or being driven to parking halls or garages.
    1
  48.  @Phrancis5 : I think per surface area a spinning cylinder creates more thrust and they have the advantage that a wind coming from a wrong direction won't exert a large force on them that could reduce the ship's stability or tear the sails off.

  49. They're replaced with streets, not tunnels. Some of the proposals were rejected but not all. One of these is already under construction (in Laajasalo).

  50. "and the wind blew full force everyday" No, the $400 was the daily average. Some days would get stronger winds and some weaker.
