I've been trying to find information about thermal airships but Google seems to mix blimp info with thermal airship info. And because they are essentially steerable hot airballoons I thought I'd ask here.
So if anyone here has any experience with them that would be a great help. Finding out things like cost, training, pros and cons, etc. would be a really useful.
I was reading the Wikipedia article on airships, and it mentions that the top speed of thermal airships [which seem to be essentially self-propelled hot air balloons] is quite slow (~15-20mph, or 25-30 km/h).
The separate Wikipedia article mentions that they have much less uplift per unit volume as an explanation, but why would this lead to slower speeds?
Couldn't you fix the "lower uplift" problem with better propulsion? Also, hydrogen is often mentioned as a better lifting gas than helium because of how light it is (however, it is not used due to its explod-y properties). But helium doesn't explode: so if you heat helium, could you generate enough lift to mimic hydrogen as a lifting gas?
I was reading up on some guys invention of using Thorium in a radioactive thermal steam generator, by bombarding the Thorium with Neutrons, it heats up as it decays into Uranium-233 or something.
At the same time I was casually watching the movie Stardust, which has a rather cool airship in it.
It got me to thinking, would it be possible to use the decay heat from a radioactive compound to generate hot air for an airship, so it wouldn't have to rely on a lighter-than-air gas?
If you could make the compound malleable so it could be made into flat plates, and then put these plates inside a heat-transfer container that looks like a heatsink. Would it work? Would it be too heavy?
Doesn't have to be Thorium. I also saw an example of Pu-238 that was glowing red hot, but it seemed rather expensive.
Hello! I need a prompt for a drawing completion “design the plane of your dreams”. I want my plane to be solarpunk themed as well as being able to fight climate change and produce energy while being perfectly efficient and good for passengers too. It can obviously be fictional but if it has science that is potentially possible like nuclear fission or Geo engineering. Once I have an idea of what the plane must be I’ll be able to designe it and draw it. Thank you
Name: Katherine Rebecca Kane
Height: 5' 11"
Weight: 141 lbs
Background
"Kate Kane survived a brutal kidnapping by terrorists that left her mother dead and her twin sister lost. Following in her father's footsteps, she vowed to serve her country and attended West Point until she was expelled under 'Don't Ask, Don't Tell.'" -- intro to the New 52 series
After her expulsion, Kate was inspired to fight crime by an encounter with Batman. She wears the Bat to honor his inspiration but operates independently of him.
Kate is also first cousins with both Bette Kane (AKA Flamebird/Hawkfire) and Bruce Wayne.
Note: Batwoman did not receive a full reboot with the New 52, leaving Detective Comics #854-863 and parts of 52 still canon despite taking place in the pre-Flashpoint era.
Additionally, Dark Nights: Death Metal restored everything in DCU history, even if contradictory. This will be assumed for this RT; thus, some examples are included that were technically not canon to the Prime Earth (New 52/Rebirth) era prior to this reveal. Such examples will be marked with a † here and/or in the image caption.
All sections are ordered approximately by in-universe chronology, not publication order. Brief context will be given when necessary, either here or in image captions. Some pages have been slightly edited to improve conciseness and/or readability.
New or updated entries are in bold.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
Alot of great jokes get posted here! However just because you have a joke, doesn't mean it's a dad joke.
THIS IS NOT ABOUT NSFW, THIS IS ABOUT LONG JOKES, BLONDE JOKES, SEXUAL JOKES, KNOCK KNOCK JOKES, POLITICAL JOKES, ETC BEING POSTED IN A DAD JOKE SUB
Try telling these sexual jokes that get posted here, to your kid and see how your spouse likes it.. if that goes well, Try telling one of your friends kid about your sex life being like Coca cola, first it was normal, than light and now zero , and see if the parents are OK with you telling their kid the "dad joke"
I'm not even referencing the NSFW, I'm saying Dad jokes are corny, and sometimes painful, not sexual
So check out r/jokes for all types of jokes
r/unclejokes for dirty jokes
r/3amjokes for real weird and alot of OC
r/cleandadjokes If your really sick of seeing not dad jokes in r/dadjokes
Punchline !
Edit: this is not a post about NSFW , This is about jokes, knock knock jokes, blonde jokes, political jokes etc being posted in a dad joke sub
Edit 2: don't touch the thermostat
Do your worst!
How the hell am I suppose to know when it’s raining in Sweden?
Ants don’t even have the concept fathers, let alone a good dad joke. Keep r/ants out of my r/dadjokes.
But no, seriously. I understand rule 7 is great to have intelligent discussion, but sometimes it feels like 1 in 10 posts here is someone getting upset about the jokes on this sub. Let the mods deal with it, they regulate the sub.
They were cooked in Greece.
I'm surprised it hasn't decade.
Two muffins are in an oven, one muffin looks at the other and says "is it just me, or is it hot in here?"
Then the other muffin says "AHH, TALKING MUFFIN!!!"
Don't you know a good pun is its own reword?
For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂
It really does, I swear!
And now I’m cannelloni
Now that I listen to albums, I hardly ever leave the house.
Because she wanted to see the task manager.
But that’s comparing apples to oranges
And boy are my arms legs.
Heard they've been doing some shady business.
but then I remembered it was ground this morning.
Edit: Thank you guys for the awards, they're much nicer than the cardboard sleeve I've been using and reassures me that my jokes aren't stale
Edit 2: I have already been made aware that Men In Black 3 has told a version of this joke before. If the joke is not new to you, please enjoy any of the single origin puns in the comments
They’re on standbi
A play on words.
My daughter, Chewbecca, not so much.
Pilot on me!!
Nothing, he was gladiator.
Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.
This sub is mostly just NSFW puns now.
If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.
Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
Or would that be too forward thinking?
