  1. Here's the thing about Brazil. Our cheapest brand new car takes 4 years of minimal wages to get, that's without factoring interest rates that are also high. BYD cars will probably be the only EVs we will actually be able to afford.

  2. I think these makes a lot of sense when compared to hydrogen. For example, you don’t need cryogenic transport, specific pipe materials or reinforced tanks for transport. Also, there is nothing stopping them of using an actual battery for daily commute, with that thing actually working as a range extender.

  3. I will keep an eye out for this one. Easily the most promising battery technology to date.

  4. All I want is to see a big company going for ebikes and micromobility. Honda pitiful attempt isn't even worth mentioning.

  5. Nuclear power generates a good amount of excess heat that could be used by the population during winter. Personally, I think it is the best option for them, even if takes time.

  6.  @markharmon4963  thing is, solar and wind are also the most inconsistent forms of energy. Like you said, storage is a necessity however how much storage is also tricky. That said, no one said we need actual batteries to do the job. Certainly not the same ones that go in EVs.

  7. ​ @sterlingarcher1962 you did it well enough, there is only so much you can do to explain quantum mechanics

  8. EV cars would be a lot more fun if they were light. An electric Mazda miata would be dope.
    3
  9. Also that engine will be a great heat pump for those batteries in winter.

  10. While I like plugin hybrids I certainly don't think BYD is the right company for them. PHEVs are more complex than ICE and EVs from the manufacturing standpoint.
    3
  11. That will make battery prices skyrocket.

  12. Batteries are becoming more expensive by the day though. Sodium batteries are a must to reverse this trend.

  13. I don't know why they keep insisting on cars that they can't turn a profit on. Just build plug-in hybrids, it's not perfect but it is sustainable in third world countries because EVs have a high upfront cost, especially for imports. It fits their model just right. They also have a amazing mechanical engineers in house that could be working in such range extenders to great effect, much like toyota. That said, they were falling out of favor even before EVs so there is only so much they can do.

  14. I don't care who profits from this company, I don't care where the r&d comes from, what I care is that this company keeps working for the benefit of americans during a crisis. If anything, the injected capital and japanese expertise should do well for these guys.

  15. That's a big deal. Inertia is s big issue with these powerplants

  16.  @денисбаженов-щ1б  you can blame the people if you want however it is a fact that we have some of the highest taxes with worst returns and a overly complex tax legislation. Personally, I don't think we need more education or social programs. What we need is cheaper energy and logistics, lower rents, less and more transparent taxes so the population can actually afford to develop those fields.

  17. I would get a motorcycle to drive around the city and use the car for groceries but that’s just me. I know it isn't for everyone.
    2
  18. 5000 km of range would be better than what we currently have for trucks. It could potentially reduce the cost of everything.
    2
  19. Seems a winner for semi-trucks. Hydrogen is a pain in the ass as a fuel and battery is heavy and takes too long to charge. Plus your fuel is literal water, try making that catch fire.
    2
  20. I agree, even for ICE, with exception of semitrucks. If anything it would encourage smaller cars.
    2
  21. It makes a lot of sense to replace hydrogen. As long fuel is cheap.
    2
  22. VW is the one company where plug in hybrids makes a lot of sense. They make very efficient combustion engines and they probably could produce 3 times as much hybrids than EVs. There is plenty of people in the world that can't afford a ev and those are the ones who worry about fuel costs the most.
    2
  23.  @peterinns5136  not his fault. Some gambles pays off, many don't.
    2
  24. Of course it did, germany just closed the world's second biggest steel factory.
    2
  25. Quantum mechanics are just very weird in general but we already use it on high end tv screens
    2
  26. Nuclear powerplants are fine as it is. Even if the initial costs are higher, the cheaper energy in the long run is well worth it. Solar on the other hand should really be working with hydro and wind is very dependant on location. Batteries and insanely expensive high voltage cables for renewables really are the worst way to handle the problem.
    2
  27. You already have affordable EVs that are already popular... ebikes. All we need is to take them seriously. Ebikes are one of the few means of transport whose carbon footprint is smaller than walking.
    2
  28. If Brazil is any significant in the grand scheme of things, there is no way they will recoup their losses. Things are so extreme that people gave up on brand new cars and motorcycles have been so popular to the point where used ones are the same price as new.
    2
  29. "The age of nuclear power is over" So is the age of reliable power grids.

  30. Range extender is a good compromise for those who don't want to have a ICE car just for roadtrips. There is also the problem with ground clearance, those batteries have to go somewhere. Also, these futuristic designs are ugly. I get it, EVs but... not every truck needs to be a cybertruck.

  31.  @xtnuser5338  I don't even care about multimedia screens that much.

  32. We don't even have enough batteries for cars.
    1
  33. They should start with a hybrid. Two independently driven front wheells would do wonders for stability and traction. I am fine with full time EVs but a SUV would be heavy.
    1
  34. forget about cheap. If solid state lithium becomes a thing, it will be sold at a significant premium to the aviation industry.
    1
  35. I think we will see full time EV and plug-in hybrid options for the same chassis. That or multiple battery options.
    1
  36. This is the big deal that I want. Cost, weight and avaliability are the big 3 issues with EV batteries, this solves it all. Also battery degradation isn't a huge deal if it is cheap and easily recyclable.
    1
  37.  @денисбаженов-щ1б  well, you have the usual culprits such as covid, inflation, high(er) levels of debt and so on but something quite unique to us is our bloated tax policy system nicknamed "custo Brasil" (brazilian cost).
    1
  38.  @денисбаженов-щ1б  So do you want Brazil to innovate so a business overseas can make millions of our technology, how does it benefit Brazilians? Btw, the French minimum wage is about 6 times ours. They can afford their taxes. Second, our middle class is still poor. About the upper middle class, that's mostly the people working for the state, some make it to the top 1%. Third, Steve Jobs and Elon Musk had investors and a decent economic climate in their favor at some point. And last but not least, does it really matter if we pay more or less for energy than Koreans, Germans, British etc, if we have little money for everything else? - Koreans: 5.6x our minimum wage; - Germans: 6.4x - British: 6.9x Do you get my point now?

  39. They could just upgrade the battery eventually and turn it in a full time ev for all practical purposes.
    1
  40. @vec306  the main advantages of EVs is that it's clean to run and can be charged at home.
    1
  41. I don't want them because they are heavy and expensive. Solve that and you got yourself a new EV owner. Right now a plug-in hybrid makes a lot of sense for me and I bet the japanese could use a FCEV with a plug-in battery in the mix.

  42. A toyota prius weigh half a ton less than a tesla model s, so I don't get what weight you are talking about.
    1
  43. I wonder why these major manufacturers don't spend some serious money with carbon fiber manufacturing R&D.
    1
  44.  @Parture  the aircraft industry should be focusing on hybrid tiltrotors instead. Even a small boost during take off would save you tons of fuel in the long run, especially in short flights, and you can charge the battery in forward flight, when gas turbines are much more efficient. It allows you to get away with smaller, more efficient engines as well. It would allow for cheap interstate air travel, for example.

  45. I thought those fake transmissions actually changed the power delivery to the wheel.
    1
  46.  @michalandrejmolnar3715  no, but we didn't do it because it was supposed to. I regard compressed natural gas (CNG) as the best fuel around.
    1
  47. I don't think the Tesla Semi is a flop. If you have a fixed daily route with set range, a Semi will save you an insane amount of money. It is a big enough market for tesla to sustain itself until a new battery technology comes up.

  48. I think Japan always took EVs seriously, they just really didn't have to deal with China.
    1
  49.  @Mdude59  or we can increase the depth of the hole. We have a project with plans to drill up to 20km bellow the surface (obviously not with a conventional drill), where earth is hot enough to turn water into a supercritical fluid and raise production output dramatically. Best thing is by digging so deep we can effectively run legacy fossil fuel power plants with steam instead of building new ones. Of course it is all vaporware for now but they should start drilling by next year.

  50. I want solid state batteries on e-bikes.
    1
  51. They didn't. It's basically economies of scale, lithium, nickel and cobalt are finite resources, hydrogen is not, for practical purposes. Toyota sells about 10 times as many cars as Tesla, they simply wouldn't have the resources to feed the market with electric cars at competitive prices. Hydrogen is a pain in the ass to deal with, however Japan may have a steady supply soon enough, courtesy of the waste byproduct of nuclear energy production. Think of a country like mine, where 1.0 liter 4 cylinder engines are the norm. No one will buy a Tesla here because no one has the money to do so. And lithium isn't getting any cheaper. That's why I keep saying Sodium batteries are the big event in battery technology... IF they become a thing.

  52. Hybrid technology is much easier/cheaper to develop and implement, so not dumb at all.

  53. This is not at all exclusive to evs, of course. I don't hate evs but I am not enthusiastic about batteries and I do wish to see more hydrogen fuel cells in the future. Unless a new wonder batteries appears, of course. Ideally, I want to see batteries and fuel cells working together, so I can charge my car at home for daily commute and fuel it under five minutes in a road trip. Preferably in a way that does not spontaneously combust. I know hydrogen sucks as a fuel but massive lithium batteries aren't that great either. People put too much faith in something that could never come to the market, and even if it does, not in sufficient numbers, there are problems you can't fix by throwing money at. At least hydrogen is here, we know that it works, we know that we can produce as much as we need without fossil fuels and now we have renewables that, because they produce a lot when demand is low, could make its production viable. Yes, there is talk about producing clean hydrogen as a byproduct of nuclear energy but I haven't see it yet.

  54. I would argue that a tax based on the actual weight of the vehicle would be more beneficial.
    1
  55. Not entirely wrong. As long as I have a battery with enough range for daily commute, I don’t mind using something else for range.
    1
  56.  @electricaviationchannelvid7863  Personally, I would love to see it in hybrids. Extra torque in climbing, energy recovery in cruise and landing and that precise torque control could help with maneuvering. Plus those motors can start up the engine by themselves. Where it would really matter is in tiltrotors since you really don't need to run those rotors very fast (412 rpm for the osprey in vertical mode, from my research) and you can recover that energy in forward flight, when the engine is more efficient. The battery can be small and relatively light since it mostly matters for the first moments of flight. That fuel economy adds up fast in short flights.
    1
  57. If that battery were to happen, you can bet all the supply will be going to semi trucks or aviation.
    1
  58. I would begin to use these batteries on e-bikes.
    1
  59. A tesla van should be significantly easier than a cybertruck with a unique powerplant.
    1
  60.  @bordersw1239  for many it did more than double. Steel manufacturing will be simply gone from Europe by next year. Wouldn’t surprise me at all if that alone is responsible for the record low emissions.
    1
  61.  @dausume  it also depends on what renewables and if you have access to energy storage (no, not batteries, but dams). Geothermal and tidal is fine, wind and solar is not, but you can more or less get away with it if you have hydro. Being on a smart grid does give you some flexibility but not a whole lot. Thing is with powerplants you really don't have a on/off switch, it can take a day to rev up a turbine, so you can't simply fill the gap left by solar and wind.
    1
  62. I would be fine with that or a hybrid.
    1
  63.  @claudiomaiasantos  we are currently in the process of building HVDC power lines accross the country so we can connect hydro power from the south to the wind power to the northeast. No point in storing energy in batteries if we have dams. Obs.: HVDC stands for High Voltage Direct Current, basically a cheaper way to transport energy across long distances. Obs. 2: by "currently in the process" I mean we are still in the conceptual phase.
    1
  64. Honestly I think we should just forget about storage unless we are talking about hydro power. The amount of batteries to make renewables viable would be far more devastating for the environment than nuclear power.
    1
  65. @LogistiQbunnik  that motor is mostly (if not solely) there for cornering, you don’t need much capacity for that. That electric motor should also be what allows that v8 to comply with emission regulations as well.

  66. If it wasn't for all the weight associated with the battery, electric cars would be, by far, some of the best handling cars on the market. You have so much freedom and control with electric motors.
    1
  67. These motors are perfect for plug-in hybrids. Personally, I would pair one of those with a 1.0 liter turbocharged 4 cylinder and two clutches, one for each. Combustion engine for cruise, electric motor for acceleration and low rpm, both for range extension. No gearbox needed. Smooth and constant RPM for peak efficiency. Leanest possible air fuel mixture I could get away with. The idea is to have the electric motor control the engine rpm and have the throttle slowly catching up. At low rpms and in reverse the engine clutch disengages and the electric motor takes over. At low battery, the rpm range of the electric only mode shortens, throttle becomes a little more aggressive and once at full stop (such as in traffic lights) the motor clutch disengages and the engine keeps it spinning to recharge the battery. Great setup for a VW golf or Toyota Corolla, for example. You aren't adding much weight for that setup. Pair it with a bigger turbodiesel and a similar setup could work for trucks as well.

  68. Solid state sodium will still recharge faster than lithium, isn't it?
    1
  69. I keep telling this for a year now. Nothing comes even close to ebikes, escooters and electric unicycles. Also fast charging is an order of magnitude or two easier than electric cars
    1
  70. On that note, pedals are just cheaper than batteries so ebikes make a lot of sense.
    1
  71. Please VW, put this battery on semitrucks, electric cars can wait.
    1
  72. Government could pour those billions on e-bikes and its infrastructure. Each e-bike commuter is one less car polluting and clogging up the streets during rush hour.
