yeah looking at super old cars you can see why early electric cars were actually competitive for a while even though they were lovely heavy rear end bullshit full of lead-acid batteries

or why steam engine cars lasted as long as they did even though you needed to fill the water tank before every trip and start it 10 minutes before you actually wanted to go anywhere to give the boiler time to warm up

meanwhile i just put gas into my 98 toyota every once in a while and take for granted that it will take me however far i need to go, whenever i want, and that it'll probably last for another ten years with minimal maintenance

we will likely never surpass the energy density of gasoline with battery technology

and by 'surpass' I mean like "get within 1/100th the energy density"

even if you have to cart around your own oxygen it's still worth it

gently caress even if you have to bring the oxygen and gasoline all the way from earth to, like, mars, it would still be worth considering having a gas engine in your rover

i made some fermi estimates

weight of unloaded tank car: 110 tonnes
approximate speed: 2m/s
acceleration time to 1m/s on hitting the other car: 0.1s
total force applied: 1.1MN
contact area: ~0.28m^2 * 2
pressure between the two cars: 1964 Pa, or ~285 psi

and that's assuming it's only a single car and it is empty and it's just coasting forwards.

splort

i like this but i think some of your numbers are just a bit off; unloaded tanker car is closer to 30 tonnes for example,

also that 0.1 s i think is actually an overestimate. if we assume a train car is basically a rigid chunk of steel then the delta t is roughly the length of the train car divided by the speed of sound in steel, which ends up being something like 3.5 milliseconds

so 15 MPa of instantaneous pressure upon impact, or more than 2000 PSI :pcgaming:

(although if you assume the force gets to act through a longer distance, i.e. through a fleshy meatbag human body, then the pressure will be lower, though still quite enough to squash you like a grape getting hit by a hammer)
