Comment on Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging

zoe@infosec.pub ⁨1⁩ ⁨year⁩ ago

hydrogen is costly: it requires 44kwh of electricity to produce 1kg of H2, and that translates to 80km of mileage. while a 100kwh electric battery give u 300km mileage. also how much does a battery cost: 100$/kwh, ie 10k$ for 100kwh pack. i would gladly pay an extra 10k$ to have double the battery size, if just companies stopped being greedy and implementing stupid features like fast 0-60 acceleration, that eats up on mileage, and snake oil braking energy regeneration, and trunk aero spoiler for extra 10km mileage, for the price tag of 1k$ or god knows how much…i would gladly ride my pack at 110kmh with no brutal accelerations, and it would get me to almost everywhere i go. i shouldnt be needing a sepratae car to access remote areas, or always have to be anxious about range.

snake oil regenerative braking

da fuck.

i shouldnt be needing a separate car to access remote areas, or always have to be anxious about range. minority ? hmm, well not everyone lives in the G7 countries, so we dont have a supercharger in each 100km radius. probably there are 5 or 6 V1 tesla chargers in 150k km² surface area where i am now

How often do you go to these remote areas? how many of these areas are out of reach from you on a full charge?

  da fuck.
  
  not a concrete answer
  
  How often do you go to these remote areas? how many of these areas are out of reach from you on a full charge?
  
  not much but, but people who really do would appreciate an electric 4WD, not a cybertruck gimmick. i meant by remote that there no supercharger in 400km radius in sight
  
  i would gladly pay an extra 10k$ to have double the battery size except there is more cost to a double battery size than just money, look up how the metals are mined for these batteries.
  
  They use carbon and LiFePo4: Lithium,metal, and phosphorus, which are abundant. no more child mined Cobalt with NMC cells, according to Musk at least…
  
  hydrogen is costly, Doesn’t matter
  
  sure bro. solar generation capacity is at 200w per m². u would need to cover whole Russias worth of land to produce sizeable amounts of hydrogen. also installing panels in the desert isn’t effecient, their efficieny drops alot when they are at temps way beyond 26°c
  
  road wear if you start doubling battery capacity
  
  always has been. doubled the capacity or not. road wear affects tires and brakes more most of the time. battery wears at 100k miles or so, i am not sure, so not frequently swapped afterall

    by road were I mean that if you start adding more and more weight it will significantly increase infrastructure costs of keeping the roads maintained
    
    not a concrete answer
    
    it’s a fitting response to your non-conrete statement about regen braking.
    
    not much but, but people
    
    Oh so it’s not even you are arguing for, it’s these mystical other people.
    
    an electric 4WD, not a cybertruck gimmick.
    
    okay, what the fuck does a non-product like cybertruck has to do with anything?
    
    i meant by remote that there no supercharger in 400km radius in sight
    
    Are there people like that? I am from Slovakia which doesn’t have a great infrastructure and I don’t believe there are even people like that here.
    
    that’s an infrastructure issue, gas stations exists, they can add superchargers, it’s a complete non-argument.
    
    their efficieny drops alot when they are at temps way beyond 26°c
    
    what the fuck does desert has to do with anything?
    
    u would need to cover whole Russias worth of land to produce sizeable amounts of hydrogen
    
    no you dont…
