Discussion Overview

The discussion revolves around the feasibility of using lightning energy versus hydrogen fuel for space travel, exploring concepts of propulsion, energy storage, and the implications of Newton's laws in this context. The scope includes theoretical comparisons and speculative ideas about energy storage and thrust generation.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant asserts that hydrogen fuel propels a spaceship forward by burning it, referencing Newton's third law of motion.
  • Another participant argues that a static electrical discharge, like a lightning bolt, does not provide significant directional thrust, suggesting ion drives as a more relevant comparison.
  • A proposal is made to store lightning energy in a Graphene Tesla Coil, although the participant expresses uncertainty about achieving directional thrust.
  • Concerns are raised about the relevance of Newton's third law to the comparison being made, with a challenge to clarify the comparison between hydrogen energy and lightning energy.
  • One participant mentions that a lightning bolt contains around five billion joules of energy, while the Saturn V engines produce significantly more energy per second.
  • Another participant questions the practicality of storing lightning in a Tesla Coil, expressing skepticism about the feasibility of the idea.
  • A suggestion is made to use a second Tesla Coil to create directional thrust by crossing beams, though this is met with skepticism regarding the nature of the beams produced by a Tesla Coil.

Areas of Agreement / Disagreement

Participants express differing views on the practicality and feasibility of using lightning energy for propulsion compared to hydrogen fuel. There is no consensus on the effectiveness of the proposed ideas or the relevance of the comparisons being made.

Contextual Notes

Participants reference various energy outputs and concepts without providing specific calculations or definitions, leading to potential ambiguities in the discussion. The feasibility of energy storage and thrust generation remains unresolved.

In space Hydrogen fuel is burned and propels the spaceship forward in the direction it's facing.

Newton's third law of motion states that for every reaction there is an equal and opposite reaction.

A lightning bolt makes around Five Billion Joules of energy.

I can't find specific numbers for Hydrogen fuel burning right now but I think it would be less.

Apart from the safety hazard to other rockets, satellites and earth, what do you think?
 
Science news on Phys.org
I would store the lightning bolt in a Graphene Tesla Coil. Not sure how I would sort out the Directional Thrust though?
 
It seems more like you are throwing buzz words around. How is Newton third law related to the lightning bolt?
And what do you want to compare? Burning enough hydrogen you can always get more energy than the one allegedly contained in a lighting bolt. Or in anything else.
You store the lighting bolt in a Tesla Coil?
 
A lightning bolt makes around Five Billion Joules of energy.

Google suggests that the Saturn 5 engines delivered around 180 million horsepower = about 135 Billion Joules per second.

PS: If you want to make some sort of Electric powered Saturn 5 you will need a big "battery".

That's where I checked out, yeah. Just the term "Tesla Coil" itself is usually a red flag. Plus graphene? And then storing something in it? Yeaaaahhhh...
 
I may have figured out how to get some directional thrust going, you get a second Tesla Coil and cross the beams!
 
Exactly what sort of "beam" do you think a Tesla coil makes?

Shades of Ghostbusters here. DO NOT CROSS THE BEAMS!
