That's called "Barking".

I have a 1 liter dog that often drinks 2 liters of water and then shares what he collected about 2 seconds later out of the bark hole, not the fucking hardwoods of course, absolutely HAS to go over to some carpet and let loose. Not sure that's either barking or shitting but it's definitely something.

I have a 75lb dog that goes through 2 gallons of water a day. He's never gone in the house but everything he pisses on dies within 24 hours, my yard looks like death valley. I just need to train him to piss on certain people.

Yes. A $50K Toyota Avalon that costs more to operate than the gas equivalent. I could never use one outside the City because despite good range as there is nowhere else where I could fill up within its range.

The latest generation of electric cars have similar range with 1/10th the energy costs. They are only going to get better with upcoming battery technology. I don't know too much about fuel cells but current technology seems to be close to the maximum theoretical efficiency. Solid state batteries appear to be close on the horizon and when they hit the market it will be a game changer.

Yes, I too think BEV will win for cars for the foreseeable, but the point was really to demonstrate we can / already have made Hydrogen safe for everyday use. It is actually safer than gasoline leaks in most situations as it is lighter than air and simply disperses if it leaks. It’s hard to ignite unless it reaches higher concentrations, whereas gasoline itself and gasoline vapour pools in standard conditions and thus self-concentrates. Thousands of people die in gasoline fires every year but we are ‘used’ to it, or actually we’re not because it is very infrequently reported.

I don't think you understand what is necessary to make an airplane safe. If a car catches on fire you stop and get out. On a plane you die. If your car stops running you get stuck, on an airplane there is a good chance you will die. Runaway is the solution to a lot of failures on a car. An airplane requires failsafes and triple redundancy.

The fuel system in car generally runs in the open air underneath. Fuel can't fit into the wings of a plane so now you have to actively vent sections of the fuselage. Not a huge deal for say a General Aviation aircraft but that becomes a big issue with anything that flies at altitude with a pressurized fuselage.

You should tell Boeing that.

Anyway, I think in general you’re being a bit Old Man about this stuff. Hydrogen isn’t magik, it’s just another gas that happens to be a great energy carrier. As I said before the best cases for it are heavy transport; ships, trains, busses, coaches etc. Especially when you have some space to engineer a solution to reuse waste heat.

 

[kidwoo]

Especially when you have some space

LOTS of space

Lots of uninhabited, desert, preferably devoid of any lifeform space. And then more space a little outside of that.






Comparing the safety of petrol to any potentially new energy source as a way to minimize the already happening explosions and damage is dumb. The point is we've done dumb for a really long time now. We need to not do dumb going forward. And H2 is kinda dumb to take the place of everyday petroleum consumption. It doesn't matter how much engineering, safety and idiot proofing you do. You put a potentially dangerous system in the hands of publicly traded companies and they are going to kill people with their corner cutting. It happens with electric transmission lines, nuclear power, even hydro power. We don't need to make things fire proof as much as we need to make it capitalist proof. When a windmill fails it just sits there. When a solar panel fails it just sits there. We need more of that kind of stuff.

Actually I am trying to be an engineer and thinking of how I could make that work and I only run into problem after problem. All solvable but all end up with an economically unviable solution.

Only when it's liquid hydrogen, which is the hardest to contain. You can't store the fuel in the wings, so you take up valuable fuselage space. Structurally, kerosene fuel and even batteries are far better.

The problem is, like you say, it's a gas, and to be useful, has to be compressed under incredible pressure, and then that pressure has to be maintained. It's not just energy in terms of the ability to break carbon bonds, but the incredible pressures that it has to be stored under. I just don't see this making sense except for very limited applications.

 

[Changleen]

Avgas isn't used on any large modern aircraft for many reasons, safety being a significant one.

Avgas also isn't pressurized when stored nor is it the smallest known stable molecule.

Uhhh... Why not? You can store it anywhere you can fit a tank. The tanks are light too.

As per Airbus, trillion dollar investments across the planet, many people seem to disagree. The major point is we have to decarbonise or we all perish, so we have to solve some fairly minor engineering problems. We will/are doing so.

[Westy]

Rockets use hydrogen. However a rocket isn't as sensitive to COG shift and only the pointy bit is pressurized and holds cargo. The real issue is trying to segregate the fuel storage from the pressurized cargo volume. Flying wing planforms could get around that, but flying wing planforms have been around longer than jet aviation has and there are reasons they haven't been adopted for commercial aircraft.

 

[Jm_]

Not really??

Yes really. Other fuels are way higher energy by volume, like kerosene, but if you can squeeze hydrogen into liquid form, it starts to make sense...except it requires tons of pressure. If you use it as a fuel cell, your total output is much more limited, energy density much lower.

Uhhh... Why not? You can store it anywhere you can fit a tank. The tanks are light too.

Airbus (and boeing) patent all kinds of wild shit that would never fly...not literally (well, sometimes), but practically, they do it anyway, to cover their bases. That wild lifting wing design has also been done by boeing too and no matter what fuel is used, it's a more efficient design, except it won't work with airports, terminals, etc. Ok, lots of re-engineering, etc. But to store the high pressure H2 you require immensely strong tanks, certificated for flight. This kind of reliability and engineering are beyond our capabilities. The X-33 program failed primarily due to the realities of trying to use hydrogen for a propellant other than a rocket.

What's the solution? For short hop stuff, well probably freaking trains for one, but apart from that, probably some sort of battery or hybrid solution that climbs to a max altitude and *mostly* glides back to the destination. This would probably work decent for 300 miles or so, maybe more. Most lift Cds allow for a glide of around 3 miles for every 1000, so when you are at FL35, it takes you 35*3 to get down at flight-idle, which is a decent amount of range at ~280kts. Battery energy density has a long way to go for this, but hybrid stuff probably gets us closer in the short term.

Going towards hydrogen before these inherent issues are worked out though doesn't seem to be a good use of resources, like it would be better to convert much more over to battery/electricity that can be converted, leaving less and less running on fossil fuel and those things that run on it to be highly regulated, like large bypass turbofans.

it was a joke about your hydrogen car running low in a remote area, building on westys point about recharging infrastructure being only available in cities. I was pointing out the ability to light a leak and turn it into a rocket car to make the last few miles on fumes in a last ditch effort. It had nothing to do with the minutia regarding a fucking pratt and whitney turbine.

I was pointing out the positive aspect of hydrogen in being able to light it like a fart.

I generally refuse to fly for any trip that would be under 12 hours of driving. That 2 hour flight takes at least 7 hours door to door with a solid possibility of taking 2-3 times that amount.
