Famously transporting large volumes of hydrogen has never gone wrong and hydrogen charging stations have proven very reliable and also hydrogen as an alternative to electric is definitely not a ploy by big oil to keep drilling for fossil fuels!

Good job hyundai 👍 Very credible 👍🏿

In the case of military vehicles, hydrogen is about the greenest option that we’re gonna get. No one is going to make a battery powered AFV, because where the fuck would you charge it?

Who if not the Germans built an electric tank in 2020 https://efahrer.chip.de/news/geraeuschlose-einsaetze-weltweit-erster-elektro-panzer-kommt-aus-deutschland_103179

Sounds crazy at first but comes with some good advantages: it can cross rivers as it doesn’t need air for combustion, it’s silent, and you can load it anywhere at the battle field if you have solar panels, time and sun. Still you can rely on military logistics to carry a swap battery. But isn’t the military supply chain the first target to disrupt? My two cents, this is the next thing at battle fields.

Oh, and if all your equipment runs on electricity, you can load and reload power at your needs. Tank needs power but car not? Combat robot out if power and car is full? Transfer the power

That’s true as well for hydrogen, though. And I guess there’s a higher chance of getting access to “power” somewhere in the field than finding a hydrogen tank. Also, energy density of lithium batteries is higher than for hydrogen storage.

Honestly if MILITARY applications are what kicks renewable energy and mass storage into high gear, I won’t be surprised, but I will be disappointed.

But hey, improvement is still improvement and if a military organization sees renewable as the future, they’re gonna try to make sure they get there first. As long as whoever gets there shares the progress with the rest of the world, I’m okay with it.

But who am I kidding, it’s gonna be China or the US and the rest of the world won’t see shit for decades due to suppression of research and technology that would allow for similar specs to be achieved privately…

… How credible is my aluminum foil hat guy?

I must admit though, it’d be cool to see an armored combat battery sliding across a field to quick charge a tank that died mid-battle. 10 seconds of charging to get it up and running, and the battery moves to the next low power thing. I’m imagining a semi-autonomous hot-swap of a battery compartment and eventually recharging like modern airplane mid-air refueling. Insert Rod A into Slot A and wait a little bit. The faster they want it to charge, the more they’ll dump into R&D.

Range of tanks is not super important other than blitzkrieg strategy where refueling infrastructure catches up. Even under blietzkrieg, tanks eventually get into a siege position and solar can be enough to sustain their position indefinitely. H2 is the best quick refueling method for electric heavy vehicles. A dispenser can be hidden 1 mile or so behind the front lines. Production facilities can be portable and moved forward

You’d probably want a quick swap battery and charging far from the front lines.

If you ignore the fragility (creates a weak point to disable the tank) and the slow charging rate, dust and debris from firefights would be a pretty big issue.

My dude, the military transports more volatile materials than hydrogen every day. Just because something doesn’t make sense for civilian use doesn’t mean it’s never going to be viable for military use.

If you’re worried about the dangers of transporting something like hydrogen, you’re going to lose it when you find out what bombs are made out of.

Electric motors are just more efficient in just about every way at scale, the current diesel motors being used in tanks aren’t really able to be improved upon. They’re at their technological peak, so the only way to move forward with mbt is by figuring out how to make electric motors work.

An unarmed bomb can be dropped from cruising altitude onto a hard surface and not detonate. The US military has had nukes fall out of planes without breaching the radioactive core.

Also, the energy density of hydrogen is pretty poor, diesel electric hybrid on the other hand is a proven technology.

And yet you don’t think they could produce the same safety features for less volatile materials?

Yeah, you just have to add a diesel engine, electric engine, and a giant battery…The whole point of moving to electric is to increase efficiency and decreasing the weight of primary motive components.

Military vehicles are purpose built. They didn’t use hydrogen because it was green, they used it to fulfill their requirements for a silent stealth battle tank. But I’m sure your technical knowledge far outdoes that of the people involved in designing this tank 👍 Very credible 👍🏿

Fuel cell technology will also dramatically reduce the noise the tank generates when on the move.

Literally from the article you failed to open.

H2 tanks are safer than diesel. It would make a superior tank to diesel in most ways. Quiet, electronics power, portable solar charging in forward position, H2 production in solar rear stations. In war, having all of your large oil refineries and port handling blown up the first day is common, and decentralized and portable H2 production is an important asset.

ROK while leading on H2, is way behind on both solar transition projects/roadpath and have abandoned solar technology themselves. Government does serve its industrial champions but also serves US master. US wants to subjugate colonies to its NG. Industrial champion needs clean energy independence.

Do you even realize how much energy is needed to produce significant amounts of hydrogen and then compressing it to a useful pressure? FOB solar isn’t going to cut it. Decentralized H2 production isn’t a viable thing without fossil fuels or a working power grid.

For sure, field charging of tanks should be through DC. But H2 is the solution for energy abundance that is 100% renewables based. To have enough energy every day from renewables needs surpluses on most days, and H2 production is the best use of those surpluses because it is transportable/exportable energy that happens to be cheaper than electric transmission.

NonCredibleDefense

!noncredibledefense@sh.itjust.works

Create post

A community for your defence shitposting needs

Rules

1. Be nice

Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.

2. Explain incorrect defense articles and takes

If you want to post a non-credible take, it must be from a “credible” source (news article, politician, or military leader) and must have a comment laying out exactly why it’s non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.

3. Content must be relevant

Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.

4. No racism / hatespeech

No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.

5. No politics

We don’t care if you’re Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.

6. No seriousposting

We don’t want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.

7. No classified material

Classified ‘western’ information is off limits regardless of how “open source” and “easy to find” it is.

8. Source artwork

If you use somebody’s art in your post or as your post, the OP must provide a direct link to the art’s source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.

9. No low-effort posts

No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.

10. Don't get us banned

No brigading or harassing other communities. Do not post memes with a “haha people that I hate died… haha” punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.

11. No misinformation

NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don’t be an idiot.
