problem is the efficiency of these methods (especially if using salt water). while the salt does act as an electrolyte it also amplifies the anode corrosion on top of the basic issues solar and wind have already
theblackmech yes that's a problem, but a problem before we even get to that is poor electricity storage from power companies. They're not lazy or anything it's just difficult to store a lot of electricity. That's why power companies often turn off solar panels because it's generating too much electricity when it's sunny. SuperCookieGaming 👀
Some other major requirements for hydrogen fuel cell cars: the exterior must look weird, the interior must be tacky and cheap, and the gear lever must be unintuitive--a stupid gear shifter is critical. They must also cost slightly too much money for anyone not getting them on lease deals in California to consider buying. The car companies have a pretty tough job meeting all those requirements, so I can see why they're not widely popular.
@Mark Yen True, but the Clarity and Insight are very recent models. Honda is using their brain, but not many others--what a surprise. Look at the Chevy Bolt and BMW i3, which are both just as recent and on par with the current Prius in terms of weirdness. Frankly, even the i8 is pretty weird.
There's never been a good looking alternative fuel vehicle produced. You get the once in a while prototype oddball that looks great and at least halfway practical but those never make production. Geez I'm really getting sick of these stupid auto designers.
For those that are concerned about safety, Real Engineering did a video on the matter. *TL;DW:* Hydrogen is lighter than air so it can be purged in the event of a fire. Furthermore, it doesn't pool around the car like gasoline, should it ignite. Toyota tested their hydrogen tank with a .50 calibre round. Instead of exploding, the tank simply released the gas into the atmosphere.
Aero CX - Jet gasoline its self has a very high ignition temperature, the vapor is what ignites easy. It’s quite hard to actually get a fuel leak In a wreck in any modern car. Self sealing fuel tanks along with auto fuel shut off trap the gasoline within the fuel tank. Fires are quite uncommon in car crashes for the last 10-15 years. One thing Toyota keeps ignoring is how the safety systems work in a crash, not just a puncture. You can shoot a propane tank and it wouldn’t explode either, it’s way to rich to ignite from the inside and explode. Problem comes when the hydrogen starts venting around hot metals and other workings of the car. One property of hydrogen that gasoline vapors don’t have it that hydrogen even if the gas is extremely dispersed in the air can still ignite at a very low temperature. Both have advantages and disadvantages but hydrogen cars aren’t a “no risk” vehicle by any means
Ah, good, I was very concerned about getting shot with a sniper rifle while driving on the freeway. No, I'd obviously be concerned about crashing into a gasoline-powered car, leading to all the problems you mentioned that hydrogen doesn't have still happening, only adding a pressurized tank of H2 to the gasoline fire. But good to know I can drive the thing in a war zone. They should fire a tracer round next time.
Anyone who has ever watched this series is hoping to see more. Please bring it back! Maybe it's gone because Bart ate too much cake, but if that's the case.... "Cake Garage!!"
I would love to see an episode about different drive modes, explaining what happens when you go from normal to sport or from sport to eco mode a lot of newer vehicles have different drive modes and I have no clue how they work
Absolutely love your educational car videos!! Do you think you could do a video on camber or alignment in general? There’s a huge misconception about camber these days due to the stance. It would be great if a large channel like yours could educate those on the important of camber and how they increase handling on track
It might make sense to use electricity to make hydrogen to make electricity depending on where you got it. Hydrogen then becomes the 'storage medium' for the energy. If the first electricity is from solar etc. that is a great system. Like solar energy->grass->cows->sweet, sweet steaks. Steak as a storage medium.
This video felt more intimate..... it was like the presenter was sitting in front of me, having a one on one conversation and explaining the this hydrogen shiiiizzzzzzz to me :-)
you missed the fact that there are also restrictions with the fuel cell. There are two types: liquid storage, and compressed gas storage. liquid storage being the more space efficient method, though it it needs to be cooled a lot since H2 is a gas at room temp. and comp. gas storage is not space efficient, thus mostly used by buses
There's also an internal combustion engine that works on hydrogen right? It would be cool and we would get rid from the boringness of an electric motor...
There is, for years and years there has been vehicles made that are on par with gasoline vehicles and performance. I figure they don't develop into it because it would make the billions and billions of dollars that went into EV the useless waste that it is. We have the tech for it, we just need the time and money to make use of it. Everyone bitches about how expensive it is. Well yes, everything is fucking expensive in its infancy. I mean look at EV, the investors involved just to get their tech off the ground, billionaires with nearly unlimited resources. If hydrogen had the same thing it would be better then the battery and I'd be still using NiCads in my RC cars today. One thing for sure, Hydrogen puts people in space and will eventually drive everything else before fusion and very high solar efficiency in the far future.
Broken Platinum Studios you can use hydrogen enriched gasoline but the ignition temperature of raw hydrogen is low to maintain a proper rhythm cycle. The hydrogen would ignite the instant it was introduced into the cylinder unless it’s mixed with something with a higher ignition temperature.
They have them working pretty well, even years ago. The problem is storage on the vehicle, turns out you need quite a bit of it to get any decent range out of it (think early EV). In those years they were a little bit impractical with big storage tanks. These days we are getting better an better and smaller too. Jesse James did one and it sounds great in a 572 BB Chev and BMW did one as well, both 200mph capable. We can get full water conversion in about the size of a large air conditioner. So unless you don't mind driving around in a E350 or chev commercial van then you can practically run one one the road. Filling the tank with water only.
Hydrogen powered ICE's are really dumb because you still produce NOx and COx from high temperature combustion so there is no real advantage to burning hydrogen, Aston Martin had a race car that burned hydrogen
@@ehcodes4325 I'm pretty sure carbon needs to be in the reaction to get COx from it. It's simple chemistry: CxHy + (x+y/4)O2 -> xCO2 + (y/2)H2O This may only be the formula for complete combustion, but it still stands for incomplete combustion that no C atoms before means no COx molecules afterwards.
If someone did not understand, hydrogen comes inside from one side and oxygen from the other. The hydrogen with it's electron wants to bond with oxygen and the only thing separating these two is the PEM. The PEM ensures that the hydrogen goes through and not the electron. So the electron is forced to go through an external circuit. It goes from the negative pole to the positive. Negative pole is on the side where the hydrogen comes from and the positive side is where the hydrogen and oxygen bond. When its has passed through this circuit it is reunited with the hydrogen and oxygen. Thus the emission will be pure drinkable water.
It was really hard for me, but I left engineering explained for this. I also left my classroom for this. I'm already learning more than I was in class!
I think it'd be great if you guys had a show on Velocity. I know that would kind of defeat the purpose of a RUclips channel and cable based programs aren't as popular as they used to be but you have so much content that appeals to both younger and older generations. Plus the educational factor you guys provide is phenomenal! There's tons of pros and cons to this avenue but as somebody that is an avid RUclips watcher who still watches cable, I feel like there is a place for Donut Media that could be on cable. Either way, keep up the amazing work! You're channel is phenomenal!
Can we replace gasoline with something else that burns as well, can power regular combustion engine and be as environment friendly as hydrogen? Nothing will convince me to give up rotary, you hear me? Nothing!
"We can use the sun". Yeah, very true. We can use 1/3rd less of the sun to charge a battery electric to go the same distance it would need to make enough hydrogen to drive a car as far.
im glad you guys made this i was hoping you would i think these are the thing of the future battery-powered cars will be temp I believe, simply due to as Bart said long charge times and yes they can be recycled but that doesn't remove the fact what is in batteries is not good for the environment regardless and people crash cant recycle it al now can you
Where did science garage go, Bart needs to tell me how car things work
Whyyyy
I miss this series
I miss Science Garage!!
I feel like Bart has gotten mellower in recent episodes.
Because he has nothing to destroy
They drugged him
There are many "Barts" working for Donut, this is just the mellower clone. The other clones were out of the planet for the week, doing... *things*
Too many people were complaining in the comments so he doesn’t yell as much if at all
@@lofiseeker1790 no I think the problem is that he's not drugged.
Just randomly add a clip at 1:02 from National Geographic for maximum spookedge

I got a screenshot of it

who is that?
please bring back science garage its been almost a year i miss it
if you use solar/wind power to perform electrolysis then the process is 100% renewable.
Sorta like how most electric cars dont use renewable energy.
Toyota uses wind energy to charge batteries and then generate electrolysis to get hydrogen
problem is the efficiency of these methods (especially if using salt water). while the salt does act as an electrolyte it also amplifies the anode corrosion on top of the basic issues solar and wind have already
theblackmech yes that's a problem, but a problem before we even get to that is poor electricity storage from power companies.

what happened to this series? bring it back plssssssss
Jvlbs Saldana he left donut
Zarbzyy damn rip
Best series on this channel in my opinion
Oil is technically renewable it just takes millions of years
Still faster than my galaxy note.
and a Extinction Level Event..!! maybe we will be the oil for the ones that come after us!!
The definition of a renewable resource means that resource can be replenished within a humans lifetime

You should make a video about how traction control works
Perfect explanation how it works for non-engineers !!! Congrats !!
This is probably the shortest science garage episode ever.
ThaKenMan yea miss the screaming bearded fat guy
the one on tubes??
tell Pumphrey to do holden on up to speed
for the aussies
Any new science garage videos coming soon? I love this series
banhxewheel no Bart had a kid and left Donut and they said without him they won’t be making anymore episodes
You and Engineering Explained uploaded at the same time, had to choose who to watch first

2:26 AWWWWWWWWWWWW THAT WAS THE CUTEST EXPLOSION I'VE EVER HEARD
So.... you’re telling me if I’m thirsty I could just suck on a cars exhaust?
I am wondering, if we can drink it after run the water through a water filter bottle.
I would not recommend it. As an industrial designer i know how many products use bpa containing plastics
or just put it in a cup and drink it normally. But if you want to suck out of a pipe, you do you
Donut is lord and donut is life
