  1. 100% agreed. The situation is ridicolous. Companies just don't want to sell the parts unless forced to. Yea because with the electrics they can lock them down really good and only let "authorized" dealers do repears. The lawmakes need to step in or it's going to be really ugly. "Right to Repair" is something I fully support. It needs to also make sure parts are available at reasonable cost with just a small profit margin for the manufacturer. Well it's not exactly an H bomb which is a fusion bomb. Hydrogen ICE cars don't do that luckily. But yes they are rolling bombs and no further development can change that physics fact unfortunately. They can make the tanks safer but they can't eliminate the risk completely. When it does happen then it's ugly because the explosion is so fast and violent.
  2. Well, that's what fusion reactors will be doing. Using hydrogen isotopes like tritium or deuterium to fuse them into stuff like helium. I'm not scared of someone ending the world. We already had hydrogen fusion bombs for decades.
  3. I haven't mentioned anything like that. You seem to put me into some kind of group of people that I don't belong to.
  4. Have you calculated how much more energy per kilometer driven a lithium battery powered vehicle uses compared to fuel cell? And then compare to electric efficiency. Because what you really care about is dollar per kilometer driven, that's what matters. The result does not favor fuel cells. And that's why they didn't gain traction.
  5. Hydrogen bombs use hydrogen, they don't produce it 🙂
  6. What gymnastics? Every EV owner that I know is just using the car totally normally. And as mentioned we are seeing already Li batteries approaching cycle times of 2000. Enough to easily cover the lifetime of the vehicle for most private ones. Once you reach lifetimes of 20 years there's little point in improving further.
  7. Doesn't help if hydrogen is more energy dense when used in a hydrogen combustion engine which just extracts a fraction as useable power to the wheel. The weight of batteries in EVs is less than a third of the total weight. And the hydrogen is not weightless either. So there is just a percentage of less efficiency due to added weight. As for regen breaking: hydrogen combusion powered cars can't store that as hydrogen because the water is gone through the exhaust. So that leaves fuell cell vehicles. Their weight advantage is minimal and I'm not sure if they can do electrolysis as fast. They probably buffer the generated power in batteries and/or capacitors first.
  8. H is about 3.5% of the energy in the universe as far as we currently know. Conventional matter itself is just 5% 🙂 Makes me think... we should probably look into dark energy powered vehicles. That's like 69% of the universe... nice!
  9. Water as in hydrogen and oxygen? I'm confused by your post. You can't power something with just water unless it's a water mill or hydro power station at a dam. Or maybe a steam engine?
  10. What would you do with that? Inherit it for the next 10 generations of your kids? That's hundreds of years of fully discharging and charging daily. As soon as a battery reaches 5000 cycles lifetime it's already much more than good enough for the lifetime of a vehicle. Heck, even 2000 cycles is probably more than enough for most people who would need one charge every couple days and it'll last 20 years.
  11. People think it's easy to build a hydrogen infrastructure. I'm not sure why. The existing gasoline stations can't just be used as-is. The underground tanks are not built for high-pressure hydrogen storage. The pumps are not built to handle hydrogen delivery. The delivery trucks are not built for hydrogen. We do not have the necessary hydrogen generation plants. None of it is. And where do you think the electricity will come from the generate the hydrogen? All you get is concentrated power usage rather than distributed one. That ignores the issues with hydrogen. Like explosion risk. And that wont ever go away no matter the technological development because that's what hydrogen chemically does. In german the alternative name for hydrogen is "Knallgas" or literally translated to english "Boomgas". Guess why. I've whitnessed a hydrogen explosion in a chemistry lab. Not looking forward to experiencing that again. Anyways, you speak about the development of making fuel cell construction easier/cheaper. Well the same applies to other batteries! "Extraction" of hydrogen is already easy. You just split water via electrolysis. But the round-trip efficiency of electric power in and then power to the wheels just never will be as efficient as conventional batteries especially for hydrogen combustion engines because they waste too much on heat. And so they will cost more per kilometer to operate. That you have to deduct from higher purchase/repair costs. You are making the mistake of looking at currently widely used battery tech vs what is coming. There wont be long charging times. There wont be low cycle lifetimes. Look at phone charging times. They used to charge with 5W and hold something like 5Wh. Now we have phones that charge more than twenty times as fast! And they hold more than triple the capacity. LTO batteries already have cycle durability of up to 10000 cycles. More than enough for the lifetime of the vehicle. That's like a full charge every single day for 27 years. Toyota has bet on hydrogen in the past and it was a massive failure. They fired their CEO due to that. Now they are back to banking on normal battery tech. GM is a joke of a manufacturer and on the way out. They are making so many horrible decisions it's not funny. Just recently they announced to discontinue support for Apple Car Play which will make them lose more customers. I don't look at them as an example for smart decisions. Every other big manufacturer is on lithium based battery tech. That's where the investment goes. Somehow all that money thinks it'll work out.
  12. I am not talking about current EVs. I totally agree that the current EVs are not the be-all end-all solution. But the thread is about electric vs hydrogen and in terms of the future. The costs you mention for replacements of high-tech parts like an ECU are something that always trips me up. The prices the manufacturers quote are nowhere near what they cost to produce. They simply don't want to sell the parts, they'd rather sell you a new car. I've had a little ABS control unit fail on a motorcycle. Price? 90k THB. Totally absurd. Costs them probably something like 2k THB to produce. I'm with you with waiting a bit before making the switch. There is currently too much rapid development going on and so current models will depreciate fast. Right now I'd prefer a hybrid. And that's what I bought and love the smooth instant torque down low. Next one might be a BEV though in something like 5-10 years.
  13. Maybe a good reason then to finally upgrade the grid? They did it here and the only outages I've had in years was when they did the upgrades. But using this argument would you then rather see highly explosive hydrogen tanks rolling around when there is so little care taken? When there are so many accidents? I never said that batteries are immune to damage. Obviously nothing is. I just said that they wont be damaged because a rock hit them. You talk about accidents. Of course engines get broken during accidents. Cars are in fact designed so that the engine compartment acts as a crumble zone that takes the hit and deforms so it can absorb the energy of an impact and less is transfered to the passengers. Of course insurance is higher for more expensive cars. The site says 25% higher repair cost. Well EVs are also about this much more expensive than normal ICE cars. It's a new technology that is being deployed. Of course it costs more in the beginning. Prices for batteries are coming down fast as mass production ramps up and development makes them cheaper to produce. That there is only a 25% premium right now already is amazing.
  14. Source please? We are already seeing cars that can charge in 10 minutes from for example Toyota. Will take a couple years but we've done more difficult and expensive things. Progress takes investment. Why do you want to have a grid that can charge all vehicles fast at the same time? Most people neither need to charge fast nor all at the same time. They can charge the car through the night. How does a rock hit the battery? They are behind a metal sheet. Did your car ever have a rock penetrate into the engine compartment? No? Why? Solid state batteries are a much much lower fire hazard. Again you are thinking of current state and not what is coming in the near to mid term but are dismissing future progress due to that. BTW I'd take an EV battery fire over a hydrogen explosion any day. Batteries can be recycled. Why would it cost more to buy a battery than a new car? Batteries get cheaper all the time due to rapidly progressing development.
  15. The grid can be easily upgraded to support any load that EVs can demand. It's really not difficult. Has Norway had any grid failures yet? There are more than enough minerals to produce the batteries we need. The fossil fuel industries propanda that claims otherwise is just FUD. We've just started looking more for deposits due to increased demand in recent years. The arguments against BEVs are always just thinking of the current state as if no further developments would happen. Hydrogen be it as combustion or fuel cells has existed for decades. It hasn't seen any noticable adoption and I'd rather not see high pressure hydrogen tanks parked in garages. Fine for trucks though imho.
  16. Time for some education https://climate.mit.edu/ask-mit/why-do-we-blame-climate-change-carbon-dioxide-when-water-vapor-much-more-common-greenhouse
  17. Hydrogen is not a power source. You split water with energy into Hydrogen and Oxygen and then burn the Hydrogen together with Oxygen to release energy. It's more like a battery. You don't gain power by storing it in Hydrogen. It doesn't solve any demand in power. Ah yes. Fly to Mars, split water into Hydrogen, transport it back to Earth. That makes sense. Wait, Earth is covered two thirds by water, why do we have to fly to Mars again?
  18. I'm happy you realized that he didn't say what you claimed. Good dog, have a treat 🙂
  19. As usual you are twisting things around. He said no such things as you are claiming. But I'm not surprised that a notorious covid misinformation spreader is also spreading misinformation on other topics. In fact, the use of Sanger as a anti-Wikipedia argument grew from the covid conspiracy corner. If you want to dispute the facts quoted from Wikipedia then provide facts from other trusted sources to the contrary. The claims against Navalny have to always be seen as highly suspect given the long history of Putin brutally crushing any opposition and the many people murdered because they became a threat to his authority. Putin is responsible for thousands and thousands of deaths. He made Russia a society which is incredibly corrupt and abusive. An absolutely evil person.
  20. That message suggests there is some javascript running on the page that consumes tons of CPU resources. Could be some crypto mining ad for example. Or some broken scripts.
  21. A contract is a signed statement that a person agrees to voluntarily waive some of their rights or takes on additional obligations. They are not forced. Only in some countries and in some rare cases can a person not waive specific rights (e.g. universal basic human rights or rights that by law are specifically stipulated as non-waivable). My point is AirBnB could ask guests and hosts to waive their right to sue for defamation when participating in their platform. It was just an example but it's worth checking if any clause exists that could help the OP in any way.
  22. You will get some refunded but here are caps for "reasonable expenses and fees" which are way lower than real world costs. My company won a case and still was sitting on most of the expenses.
  23. No it does not align it with the EU's emission standards which have been on Euro 6 for 10 years. Euro 5 which Thailand is adopting was from 2008, 16 years ago. It's not a bold step. It's an incredibly overdue step that is lagging behind one generation of standards and there is no enforcement anyways as evident by the rolling black smoke spewing trucks. Let's not kid ourselves.
