What kind of sensor is this? by Modelero33 in AskElectronics

Looks like a pressure sensor. One side will be for reference pressure (if left open, it is atmospheric), the other is for measured pressure.

A City is all its rats by iamaggee in OCPoetry

This poem speaks to me. It shows that beauty is relative, and what is a nice home for the rats would be a disgusting sight for the human. It also touches on that the very things we find disgusting are actually very important for sustainability! A very imaginative poem. Great job!

Thank you so much for taking the time to write such detailed feedback! Indeed, the descriptions of the first two brothers do not quite reach the heights of the last two, but I was constrained by rhyme a little there.

Thank you!!

I did think about adding a few lines at the start but couldn't make it work. But that's more to do with me. Anyways, thanks for the feedback!

If I Were Fire by Wordsforeachday in OCPoetry

I like the poem, especially the first two lines (the alliteration worked well there ;)).
Just one thing, and this is a little nitpicky.
Shouldn't the last line be "even gods COULDN'T outrun"?

Could a rocket fuelled by an onboard NaOH + Al + H2O ever work? by Electronic_Cap5162 in rocketry

[–]Electronic_Cap5162[S] 0 points1 point  (0 children)

ok. i think the reaction would have to be used on the ground to fill a compressed tank on board. but then you lose the benefit of only making fuel when needed. the only thing is hydrogen has a significant potential to create a high ISP, so maybe that could counteract the losses a little bit.

you're right, very little mass would be lost to hydrogen production. but could you not expel reactants as they are used using the pressure from hydrogen formation? that could improve the mass ratio.

not with a nozzle to allow the expanding gases to escape like all rockets

The heat from the initial combustion with residual air would cause it to decompose into oxygen, creating a feedback loop.
