    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?

          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.

        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

          Any reasonably sized pv installation near a battlefield will definitely not look suspicious on reconnaissance images.

          Tanks are going the way of the battle ship though. Drones are doing a lot of the stuff they can do, and a lot of things they can’t.

            I’m not super familiar with the matter, but what do you mean by “going the way of the battle ship”? Do you mean they’re becoming more obsolete because of their size/utility compared to drones?

              That, and expense. Tanks cost millions, while a $5k drone with an RPG strapped to it can take it out and exploit the weak spots.

          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.

            Just wait some years - they have solid state batteries close to industry ready. That means huge increase in capacity and no issues with temperature.

            Next stage will be structural batteries where you take the structure as battery. For a tank that means all the armour will be charged and work as battery. Just a matter of years.

            Loading time is solved already. It’s a matter of battery temperature while infusing power and solved by battery management software.

            Any idea why the Boston Dynamics robots aren’t on a battle field? I mean the do incredible stunts. It‘s the battery. Lasts for around 2-3 hours. Today. Military is working on that, I‘m pretty sure.

          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.
