Yeah tbh i talk poo poo about BEVs but it's a step. The next step is to bukkake spray pebble bed reactors everywhere and cover 10% of abandoned arizona desert with solar thermal plants, which would power the entirety of the united states for free for 30 years until they need to swap out the sodium

KOTEX GOD OF BLOOD posted:one of the main reasons tesla is ahead in this game is that traditional carmakers dont actually want to sell you EVs, which is why they've been trying to sell you hybrids, or lovely EVs, or make big noise about technologies like hydrogen that will never, ever be an actual market force. now that they are actually being forced by investors and public policy to start making decent EVs, they are trying, but their products still, by and large, suck major rear end in a top hat is there a like a cost thing, laziness?

Fuzzy Mammal posted:is there a like a cost thing, laziness? Toyota is all like: Hey yeah, we've been in the battery game for a while with the prius and while it makes for a neat accessory with the kinetic energy recovery system giving the drive train a little boost, the downsides of battery-only are too many. Long charge times, sucks in cold weather, limited range, and general wear and tear. Replacing the battery in a prius is like, $2k? And replacing the battery in a Tesla is somewhere around $20k. That's a big 2nd and 3rd owner's problem. They are really beating the drum on hydrogen, all the perks of quick fill ups with none of the emissions. Two big problems to overcome, first being infrastructure of hydrogen stations. Nobody is going to build them if there are no hydrogen cars on the road, and nobody is going to buy the cars if theres no hydrogen stations. The second problem is the fuel cells are like, fifty bajillion psi and that's one hell of a bomb going off in an accident, or if they are not properly maintained. But toyota seems to think they've got this licked with advanced material science and they sell a hydrogen car in california and hawaii. Behold: The Toyota Mirai:  I think they are neat. Also, RWD

Inhales oxygen, combines with stored hydrogen through "chemistry" to charge little battery, battery powers electric motor. pisses water about the best of my understanding PS: Echi, you and me got the same taste in cars I think.

echinopsis posted:so it’s an hydrogen internal combustion? no, it's a fuel cell, which is like a battery where instead of recharging it when it's dead you swap out the exhausted chemicals inside for fresh stuff. then the next logical step is putting pipes on the ends so you can have a continuous flow of chemicals through the system from some larger storage tank. the energy comes from the same place as burning hydrogen (the binding energy released when you combine hydrogen and oxygen into water) but it's done through an electrochemical reaction that directly creates electric current. hydrogen fuel cells are a great idea in isolation. the problem with them is that hydrogen is a loving awful fuel logistically. it's a gas at everything but extreme cryogenic temperatures, and not just any gas, but one so tiny that it tends to leak past every known sort of seal and valve. also as a gas it's very light, so the only way to get reasonable energy density is to compress it at hundreds of atmospheres in carbon fiber tanks that go off like a bomb if breached. it's also difficult to store and dispense at fueling stations, and the only eco-friendly way of generating it is through electrolysis, which is inefficient and requires tons of electrical power (i.e. nuclear). i personally think that the way of the future is the direct-methanol fuel cell. it generates electricity just like a hydrogen cell but it's fueled with methanol, which in turn can be made sustainably through fermentation. or just bioengineer some algae to produce it and grow it in a giant patch in the gulf of mexico. as a liquid fuel, methanol has far better energy density than hydrogen and it can be dispensed with a bucket and a hose. DMFCs produce carbon dioxide as well as water, but less of it, and if it's originally from biological sources instead of fossil fuels it's carbon-neutral. those cells aren't available in a form that is suitable for cars yet, and we don't have the gene-hacked algae. hopefully soon

i might be off on this but i feel hydrogen fuel cells made much more sense 10-15 years ago, but high density batteries have become so much cheaper and more widely manufactured that nothing else is competitive at this point. the real advantage over any alternative fuel be it hydrogen or methanol is the infrastructure: everyone with a home has the capability to charge a car; even at 120V 90% of people can get the range they need for daily usage with an overnight charge

Thanks for this. I think it was something you said ages ago, similar to the last paragraph, about us eventually coming back to using carbon fuels because their energy density and ease of use leaves everything so far behind Jenny Agutter posted:i might be off on this but i feel hydrogen fuel cells made much more sense 10-15 years ago, but high density batteries have become so much cheaper and more widely manufactured that nothing else is competitive at this point. the real advantage over any alternative fuel be it hydrogen or methanol is the infrastructure: everyone with a home has the capability to charge a car; even at 120V 90% of people can get the range they need for daily usage with an overnight charge its not hard to find material on peak oil or whatever, but are there simply enough children in the congo to mine cobalt at the rates required to make the worlds batteries

Chris Knight posted:biggest problem with liquid metal batteries are they operate at like 500C, so there's still a LOT of work, especially on the materials side, to be done getting them up to any sort of scale apparently the energy necessary to keep them at temperature is made up for their better efficiency compared to lithium. iirc the big obstacle now is making the ceramics necessary to house the batteries but it's mostly a scale thing, not an engineering or science problem

KOTEX GOD OF BLOOD posted:this but the other, possibly larger reason is parts. the car industry is pretty low margin and a lot of that is off parts, unfortunately BEVs lack a transmission, exhaust system, fuel system, and tons of other things. essentially DLC for cars, and often poorly engineered ones that conveniently break. it’s estimated that the lifetime cost of ownership of a bev is 10k-15k$ less than an ice vehicle even taking the higher initial purchase price into account

hydrogen is a dead end because of the reasons mentioned above. compressing hydrogen to useable levels take a huge amount of energy. it doesn’t make sense. it’s clear that battery electric cars are the future, unless some tech breakthrough comes along in the next few years. batteries increase in capacity at about 10% per year. the prices are high now, but they are coming down. by 2030 BEVs should comprise a big majority of new car sales.

yeah, now that it's possible to make a battery car with equivalent range to a gas car, the main downsides are just cost and charging time. (and resource usage, but shifting away from oil probably evens it out some). once you have an electric car that can charge say 10 to 90 in half an hour, which exists today, and that technology is built out everywhere and not just tesla stations, you've taken away most of the downsides. and you get the huge benefit of being able to refuel at home and transfer fuel anywhere instantly with wires instead of trucks. the charging time is the real killer though. the fastest chargers today can do something like 200 kilowatts. an average gas pump dispenses energy at a rate of 22 megawatts, 100 times faster
