Is emission-less propulsion possible? I believe it is... [View all]

Last edited Wed Dec 13, 2023, 11:54 PM - Edit history (2)

This is from my chat in the DU lounge. I would like to figure out ways this might be useful in the fight against global warming. I think momentum based propulsion would be cleaner and much more environmentally friendly... not to mention faster. Maglev trains with this technology could get you from New York to LA in hours... and be clean as a whistle.

Isn't this forum supposed to be at least partially science-based? NCIndie Dec 2023 #1

How lovely... and your proof that it's wrong is? mikelewis Dec 2023 #2

I really hope this is all tongue-in-cheek. If so, that's one for you! Just in case... NCIndie Dec 2023 #5

Ok... please read a little farther down the post please... There is no plan for a shotgun based propulsion design... mikelewis Dec 2023 #7

I'm not an AI robot and your challenge was based on scientific inquiry. I responded in kind... mikelewis Dec 2023 #11

The recoil pulls the gun away from you? Indeed... but not completely.... mikelewis Dec 2023 #29

Interesting topic.... Think. Again. Dec 2023 #3

I think you're missing the point... none of those are useful for extended space travel... or can reach similar speeds mikelewis Dec 2023 #4

My apologies... Think. Again. Dec 2023 #15

All of those have a terrible carbon footprint. mikelewis Dec 2023 #21

It's an interesting concept... Think. Again. Dec 2023 #35

Interesting. You mean no CO2 emissions during the operation of the vehicle. NCIndie Dec 2023 #6

This isn't about the energy required to run it.. that's still a problem... for a bit... we first have to see.... mikelewis Dec 2023 #8

Innovation starts with skeptics being skeptical. I'll take that role. NCIndie Dec 2023 #10

I built this idea fighting A for the past year... lol... so thank you I do appreciate skepticism. It built this idea. mikelewis Dec 2023 #12

Be combative! NCIndie Dec 2023 #13

That is precisely why I am here... I have had my ass handed to me so many times on this forum.... LOL mikelewis Dec 2023 #14

Ok. Namely....? NCIndie Dec 2023 #17

Namely what?... Think. Again. Dec 2023 #18

You're going to build a car with zero carbon footprint because of renewables+nuclear? NCIndie Dec 2023 #19

Yeah.... Think. Again. Dec 2023 #20

What about the force the projectile is exerting against the curved barrel? sl8 Dec 2023 #22

Correct! However... it's much less than you think... I was shocked too mikelewis Dec 2023 #23

I hate ads 😏 mikelewis Dec 2023 #24

And to prove that... here's all the math... mikelewis Dec 2023 #30

Why this is actually inline with physics... mikelewis Dec 2023 #32

The apparent paradox arises from a simplified view of the situation and is resolved when considering the full complexity mikelewis Dec 2023 #33

This part of the argument is where chatgpt is completely botching the physics. Salviati Dec 2023 #37

Chat GPT is not a content expert. Salviati Dec 2023 #36

You are most certainly correct... mikelewis Dec 2023 #39

I don't understand, what does the letter 'O' have to do with it!? OKIsItJustMe Dec 2023 #40

You are most certainly correct... mikelewis Dec 2023 #61

I wouldn't trust ChatGPT to count my toes accurately. It wasn't written to do that. OKIsItJustMe Dec 2023 #41

This is one of those things... Salviati Dec 2023 #43

It's an EmDrive. Better tests eliminate it. Bernardo de La Paz Dec 2023 #54

There's still some dispute OKIsItJustMe Dec 2023 #58

The IVO has test in orbit, past the minimum 1 month pre-test orbit Bernardo de La Paz Dec 2023 #60

Frankly, I don't expect it to succeed either OKIsItJustMe Dec 2023 #63

Why would I pretend such a thing exists? mikelewis Dec 2023 #69

Not logic. "view count" is not equal to "copy-paste" nor equal to "don't understand the math" Bernardo de La Paz Dec 2023 #62

Why on earth do you think I would be trying to use logic against you? mikelewis Dec 2023 #64
