when someone says they are Ukrainian what does that even mean? the "offifial narrative" that history started in 2022 is in direct contradiction to the "official narrative" that Russia annexed some stuff before 2022... there are no nazis in Ukraine but the Canadian parliament gave a round of applause for an old Uke who worked for Hitler... I'd say there is an argument to be made for not a real country. it's a patchwork of stuff left over from WW2 and the collapse of the USSR. and the Ottomans before that. the globohomo witches and wizards had an easy time setting Ukrainians against each other. so, this poast guy who says he's Ukrainian, what oblast did he come from? what was his first language? orthodox or latin rites or atheist? there are a lot of micro-details to this "country".
with all that said, of course Sweden is working on not being a real country, so... real countries have their borders set and reset by war, which is currently underway. no doubt there will be some hurt feelings.
I'd just prefer Brandon stop escalating toward a nuke exchange with Moscow.
.. in which case, you are essentially running on aluminum. why not just run an electric motor on an aluminum primary cell?
Like the lithium borohydride, it requires more energy and chemistry to re-make the fuel. the byproduct is aluminum oxide, send it back to the bauxite plant...
Yeah, you might as well run your engine on hydrochloric acid.
There is just no way to store hydrogen in a small container, with any efficiency. Lithium borohydride is a pretty compact source, but at the end of the journey you have lithium borate, and a whole lot of chemistry and energy is required to recreate the hydride. Some rare and exotic metals, like palladium, can store hydrogen -- which defeats the purpose of lightweight energy. Liquefy it, like fuel for the space shuttle ... it is ridiculously cold, and explosively boils if you look at it wrong. Or compress it, for a very short ride before another fill-up is needed. Or you can tow a zeppelin on a long umbilical leash.
the name 'cetane' for that molecule is a nod to the whaling industry, the original source of those lovely biological oils. palmitic acid is the corresponding 16-carbon acid ... they are not merely from whales and palm nuts, these oils are widespread in nature. the biggest objection to using e.g. olive oil to power your car is that bio-oils contain other gunk that clogs pumps and plumbing, and encourages the growth of oil-loving bacteria and fungi. diesel injectors squirt the oil thru near-microscopic holes into the combustion chamber, can be fouled by small particles, and are hard to clean. (and of course, that is why used cooking oil is transesterified to make biodiesel, even though it would sort-of work without modification)
combine 2 ethanol molecules to make butanol, and it is even better. the longer the carbon chain, the more like an oil or wax it is. among the alcohols, butanol may be closest to a drop-in replacement for octane. no need to re-tune your engine, or worry about corrosion.
The laws of thermodynamics still apply. To reverse the process of making CO2, you must expend a lot of energy. More energy than you produced burning the carbon. The carbon we burn today was stored sunlight from photosynthesis in a forest or a swamp full of green slime algae. (or if you're a fan of 'abiotic' carbon, it was ??? energy left over from planet formation) ... but it's silly to think it makes sense to reverse the process and turn CO2 back into hydrocarbons on an industrial scale. If you have a nuke plant, do something useful with it like powering a steel mill. Sequestering carbon is a fool's errand.
We already have ways to sequester carbon, they are called trees.
