Jon's question was whether he should interpret the 2 oz of thrust to mean that only 2 oz of material can be moved.
Yeah, in the context of being on the ground, in some kind of vehicle or something.
quote:
I understand the importance of getting power without having to tote around an exhaustible fuel supply, but I don't really understand just how much power the research in these articles is reporting.
What's 720 mN of thrust? How about 30-50 micro-Newtons?
Could this have applications on the ground?
Can you not see that he is trying to wrap his mind around how much power this is by comparing it to the kind of ground transportation that we are all already familiar with?
Then you interpret that to mean that Jon is only asking about applications for ground vehicles? Where do you get that?
I already quoted the context to you. Here, let me paraphrase it:
"This is cool, but I don't get how strong it is. Does it have applications on the ground?"
-well, its only 2 ounces of thrust
"Oh, so you can only move 2 ounces of stuff with it?"
This isn't a deep interrogation of the underlying physics behind the power of thrust in a friction-less vacuum, this is a question about how much weight can be moved along the ground with the power that this new thing creates.
