"you're still stuck on eroei
you need to describes the initial steps of eroei"
and dont geteme wrong, there are other things to consider than eroei, but solar is generally worth it in those contexts as well. things like mining issues, ecosystem damage, carbon costs, etc. of course those were not what were being looked at in the article, just someone's first attempt at eroei from first principles without understanding what they were critiquing.
hydrogen for ice and broadly for a power plant is unlikely to be particularly feasible for some annoying engineering problems and because we just need hydrogen for other stuff (farming mostly).
the problem in their analysis is itentirely lacks context. they never use any numbers to illustrate that this is unsustainable, just as a spooky ambiguity when convenient to the very very silly point. here is an example of the questions they should have asked themselves:
"aluminum uses several kWh per kg!", ok, how many kg of al per panel? how many kwh will a panel produce per kg of al in its lifetime? is that amount not only more, but sustainably more? (the answers generally are: a bit, a lot, yes). this is what those "critiqued" analyses are doing, and much more.
everything impacts the lifespan and thermal load will be a big one, as well as charge rate. those recommendatiuns take a very complex set of variables and simplify it into a balance of memorable and useful.
nail on the head. "the analyses are flawed and ill show you why!" doesnt do any analysis or dispute of methods. in fact going into even less detail in describing the costs of the process than essentially any analysis being vaguely critiqued. waste of time.
neither are jerks, they simply are what they are trying to survive hostile environments best they can with what they have.
removing unnecessary abusive misogyny != puritanism. hilariously different things in fact
why care that they removed it at all?
that is called a missile, not a drone. no consumer uav are doing what you are suggesting, and different uav respond to jamming in a huge variety of ways.
