If there were hydrogen stations near me I would love a hydrogen car.
Hydrogen chad makes a point
Hydrogen fuel cells are feckin’ awesome
Ohh boy lemme see where the nearest Hydrogen cell fuelling station is….. London, so on my way home from work I’ll just make a small 2hour detour there then a small 2h journey back yep I deffo want to be the Chad.
Hydrogen is energy negative. It takes more energy to compress it than the amount of energy you get out of it
@Unoriginal, true, but the biggest selling points for any product is cost and convince. if it's comparable in price and is more convenient then people will buy it.
@Unoriginal, hold up, if you got more energy out of it than you put in it would be infinite energy?
@daweim0, yes, if we made fuel ourselves like that then that would be the case. However, the amount of energy gained from oil in the ground to in our cars is net positive
@Good Pineapple Pizza, from a business standpoint I could see that making sense, but from an engineering perspective it isn't worth it. If the point of hydrogen cells is to be sustainable energy then hydrogen isn't sustainable. If the point is to sell it and make people feel good because they think they are being ecofriendly, then it meets the mark
@Unoriginal, bro, hydrogen cars put out water vapor as exhaust. We can make that hydrogen using electricity from moon's gravity and wave energy. If that's not freaking sustainable then I don't know what is.
@Unoriginal, unless you do like Norway and use Hydro electric plants, solar, and wind to preform electrolysis on sea water to split the hydrogen off the oxygen. While it is still a net loss, the power is renewable and transforms the energy to a portable and more usable form.
@Sr5turbo, look up the ecowave wave form and the solar dome. these both have massive potential to generate energy and fresh water from seawater.
@Unoriginal, You do get there is mote to determining the environmental impact than just what it takes to make? Like yeah we don’t have to put much energy into oil to make gas, but we can’t make oil and the byproduct is cooking our planet.
Hydrogen is the future
Don't forget that hydrogen is super explosive. Hence why it's not main stream yet
@dauneric0, hmm, just like gas?
@jkos171, waaaay more so
@jkos171, gas really isn't all that explosive. It doesn't burn fast enough. And cars are built in a way that even if it does ignite, there won't be enough buildup of pressure for the tank to explode. the weakest points in the tank would go first. Unless you are in a michael bay movie, then watch out
@TheGoogler, so why wouldn't they engineer the same safety concepts and standards for a car that ran on hydrogen?
@jkos171, when I say "built in a way" I guess I mean more along the lines of "incidentally". Also, hydrogen is violent. Meaning that it burns up extremely fast especially when it meets oxygen, or anything it can react to. While gas vapors are not. There would have to be a way to let extreme amounts of pressure be dissipated almost instantly, like a controlled explosion. Which would probably be hard to implement as a safeguard. But idk, I'm not an engineer lol.
@TheGoogler, gas wasn't that good of fuel either when it was first implemented, but keep drinking that Kool aid man.
@jkos171, I wasn't talking about how useful either was as a fuel. Just that gas is not super explosive. Seems like you are arguing with me about a topic I wasn't talking about.
@TheGoogler, so you're saying gasoline as a vapor isn't explosive?
@jkos171, I'm saying it's not violently explosive. And it's the vapor that does burn. Not the gasoline (the liquid doesn't burn as easy as the vapor). Gasoline, when ignited is more of a slow burn. Which is why cars tend to burn for a long time when they catch. While hydrogen is a fast burn. Would the fast burn of hydrogen actually cause the tank to explode Michael bay style? I also doubt it, as there are weak points that might pop first. So, I was not saying what makes a better fuel. Just how one is more explosive than the other. Hydrogen could be safer due to the fact it burns so fast.
@TheGoogler, I think the word you're looking for is volatile. But I'm glad you looked at all the angles.
@jkos171, and @TheGoogler to answer both your questions I built a hydrogen fuel cell that had a tank of hydrogen (1/16 scale) of what a car would run on. Apon impact testing with a small flame present. I both blew up the model to smithereens but the tree it hit as well, if the tank gets substantial damage it's basically a bomb. testing was done in college with physics professor permission and their pressurized tank. we ran the simulation as if the car was rear-ended to a to scale 40 mph
@dauneric0, don't lithium ion batteries that electric cars use erupt into explosions and flames as well when they're ruptured?
@jkos171, the fallacy here is that whenever you are storing energy in a condensed stat there is always some repercussions, maybe graphene battery's can help because of being smaller and less susceptible to heat will help the energy storage solution, but again nothing will be full proof. My point is that it would be more hazardous to use hydrogen in its current state vs gasoline based off it extremely fast burning/expansion.
This meme doesn't really make a good case for the range of hydrogen cars
@Medic135, yeah, i wanted to be honest about things. if it's going to take off it'll take more hydrogen fueling stations. it's also possible to make your own at home if you want to.
*adjust glasses* ACCCTTTUUAALLYYY...despite, not only being for hydrogen, I'm actually invested in it. Hydrogen is the lightest element, even lighter than our atmosphere, it will actually float. So a hydrogen fuel cell car will, in fact, get heavier as it uses the hydrogen fuel. And....being completely serious here....I am very fun at parties. I swear.
@Drunk Pantless Uncle, you need to retake that physics 101
@Drunk Pantless Uncle, wait, liquid hydrogen is heavier than hydrogen gas
@HSA, Dont mind my my pantsless uncle, hes drunk.
@Good Pineapple Pizza, yeeeaahhh. I guess I didn't take into account the difference in weight of the gas vs liquid.
@Drunk Pantless Uncle, i have brain farts like that too
