"solar Sailing Is Impossible Also"

[half]

Moderation note: The first 11 posts of this thread were split from the “Nasa Finally Publishes Controversial Fuel Free 'impossible Drive' Paper - But Still Can't Explain How It Works” because the original post makes unsupported and silly claims.

 

Quantum vacuum virtual plasma is their secret weapon for EM drive. Impossible.

 

Solar sailing is impossible also. Cutting laser produces lot heat but zero momentum, cannot bend a flame or produce air flow. Fact in your face.

Half, you saying radiation pressure does not exists? Although it has been experimentally confirmed a lot of times....It is a small force per area (order of [math]\mu N [/math]), from our sun you have a table here https://en.wikipedia.org/wiki/Radiation_pressure#Solar_radiation_pressure

I know 1000 w laser cannot bend flame or move smoke, what radiation pressure? Maybe you have access to high power laser and try it yourself?

Readers might be amused to compare and contrast this with the linked thread, from another forum I belong to, from mid 2015:-

If sunlight able to sail spaceship, why is laser beam not able to bend a flame? Isn't photon has momentum?

The plasma on the sun's surface has no electron to change orbitals, why still emit light?

Is a flame supposed to absorb or reflect photons? I would guess only a tiny fraction if at all. So how should the flame get momentum from the laser?

A light mill with hard vacuum will not spin under any strong laser beam. There is no momentum but heat energy. Are you sure photon exists? How photon carries momentum?

LOL so now you saw that your flame example is not supposed to work, so you come up with a new example (light mill) and still have your laser. Then you suddenly question the existence of photons :D Tell me what is a laser then and what is a flame?

This is his technique. Ignore the answer and introduce a new issue. And the questions are the same as a year ago. Nothing has been learning in the interim. See this link: http://www.sciforums.com/threads/the-sun-has-been-shine-for-billions-of-years-where-all-the-photons-go.152171/page-3

 

For jcc it's forever Groundhog Day. Trouble is, it gets to feel like that for others, after a while.........

If photon has momentum, why NASA cannot use photon for propellant to replace rocket fuel? Photon travels at light speed, should be able to produce large thrust. A laser produces a lot of photons and a flame contains a lot of hot particles.

...just as predicted, no answer, but a new question.......

A laser produces a lot of photons and a flame contains a lot of hot particles.

So why did you ask in the post above

 

Are you sure photon exists?

They could, technically, but you still need a "machine (i.e one of your beloved lasers)" creating those photons ;-) which needs fuel of some kind. Or we can just use solar photons like experimentally tested in space with IKAROS
