Some sort of memedrive

*torch

photons have energy (hf)
and e=mc^2 so hf=mc^2
m=hf/c^2

If you assume the surface receives a net force in that direction from the photons, which is debatable, you must also assume that the flashlight is experiencing an equal and opposite force.

Look up photon rockets, op.

that would only work if the flashlight was travelling at relativistic speeds.

Yes, but if picture 2 works, it means that the memedrive is completely legit and you can move without expelling mass (an object with resting mass)
We know that pic 1 works.
So, ether pic 2 or pic 3 must work aswell.

Your premise is false. The torch will feel a force opposite the direction of the light regardless of what's behind it. If you attach a mirror to it like that the forces will balance.

So you can convert electricity directly to force?

In order for it to work, you need to make sure that you can abuse the forward energy much more efficient than the backwards energy. It should be possible to achieve this.

user, 2 produces thrust, it's a photon rocket.

And the point of the memedrive is that
1. the hull is closed so photons can't get out, it's not a photon rocket
2. it produces a thrust much higher than a photon rocket, otherwise nobody would care

And if you wonder, photon rockets are useless because their efficiency both in terms of thrust/energy and thrust/weight is pure garbo.

>thinks that is proof

lol kid
