Read this today. Makes me sad but also helpful.

What do you guys think of it?

tl;dr: new mathematically working method of quantum based space propulsion invented, can't be built because Egypt is too poor

I raughed.

the effect of those particles would be impossible to control, it's literally relying on random happenstance.

also, any minor influence from anywhere, heat, gravity, photons etc. would completely undo any force you could get from subatomic particles.

>>4892140
What are you basing this on? Are you seriously implying they would build something with no trajectory correction?

I'm saying that the casmir force is so infinitesimally small that just having moving part inside the ship would completely unbalance it.

you could get the same effect as this "engine" by standing on the outside of the ship and flapping your arms.

It's a propulsive mechanism. That's like saying explosions could never put humans in space because they're explosions.

this is retarded. the device would need Maxwells demon to guard one of the plates.

It's actually based on the dynamical casmir effect not the casmir force.

are you joking? that has literally nothing to do with anything that was in any of these posts of articles.

i'm talking about the inefficiencies of using the casimir effect to generate electricity, you're just getting angry because "NUH UH SPACE TRAVEL!"

Device is already successfully demonstrated, invented, patented, etc. It just needs to be applied on a more practical scale which is what money is needed for. The application is pretty brilliant.

We don't have a prototype yet. There's no point in speculating until then. Until the silicon chip was invented we didn't think computing was practical either. It's being called an invention for a reason.

wat. having a vague idea based on technologies that don't even exist isnt an invention, its an idea.

not to mention her idea would violate conservation of momentum as its a reactionless drive.

He's not me, I'm reading into the dynamic casmir effect.

>> No.4892240

>>4892224
It's not reactionless. The dynamical casmir effect creates real particles which would be the reaction mass.

>>4892208
Solar sails can fly towards the sun. They simply reduce their orbital velocity and fall to lower orbits.

>> No.4892249

so if she is using the dynamic casimir effect to generate electricity, how is she powering the movement of the mirrors?

>> No.4892255

>>4892240
> creates real particles
From what energy source?

If you say "the vacuum" you can just get right the fuck out, that's not how it works.

>> No.4892254

if you can use a sailboat to sail into the wind, why cant you use a solar sail to fly towards the sun?

>> No.4892259

>>4892255
of course, she is saying that. the article links to John Hutchisons video of how he got free energy and levitation using zero point energy.

>> No.4892258

>>4892249
From what I understood she was not intending to use the effect to generate electricity but rather use it to create thrust from electricity.

>> No.4892264

>>4892255
The dynamical casimir effect is a real part of physics and was demonstrated in labs last year. Moving the mirrors is analogous to Hawking radiation and can pull real particles from the vacuum.

>> No.4892277

>>4892258

even so, the thrust from generated photons can't be all that much, and there is sure to be effects from outside the ship that can interfere with such a small effect.

>> No.4892282

>>4892277
That's pure speculation. We don't know enough say it will work but we shouldn't assume it won't either.

>> No.4892285

so how is this any different than simply powering a flashlight aimed to the back of the ship?

>> No.4892289

>>4892285
Try getting enough thrust from that. I can't say if this will give a better power to thrust ratio but you won't be able to make a small light source powerful enough to make much of an impact.

>> No.4892295

>>4892282

it seems to me you could use the electricity that goes into moving the mirror to simply generate heat instead, that would move the ship more efficiently in interstellar space anyway..

>> No.4892298

>>4892289
and how would you get more from this? is it somehow extremely effective?
