Hey Soylent Green Is People, awhile back we thought that the human body couldnt go past 30mph, people were terrified of fast trains, now we go hundreads in planes. But i guess you do have a good point.
Take Care, Vix
The technology works by bouncing protons between mirrors and using a photon beam amplification system. The technology could be used to accelerate spacecraft to near light speed and to create space telescopes with 100,000 times better resolution.
The technology prototype generates the power of an industrial or military laser from from an egg sized head. The technology is economical and has been confirmed by repeated experiments. The institute is seeking funding to scale up the project.

Well, I'm not an expert either...that's why I asked the question
If your calculations are correct, then that is good news! Thanks.
EDIT: Not to beat a dead horse, but I got to thinking...I assume the acceleration has to be more than 1g (not 2/3g -- although 2/3g may be correct for the deceleration). So would the acceleration feel like 1.5g? (the recprocal of 2/3)...1.5g does not sound bad, but what would the affects of 1.5g be for 3 1/2 days of constant acceleration. I would think a body would not like to feel 1.5g for 88 straight hours. I assume it would be a little hard to breathe. Maybe the answer would be a short acceleration time with greater g-forces.
The ISS and the space shuttle are in a free-fall at a constant speed of 17,000 mph +/-, and it's that constant speed that gives the astronauts a feeling of zero-g's.
Maybe they could use the acceleartion of this new propulsion system to create an artificial gravity environment.
I'm not criticizing your computations...I'm just wondering what it all means to human physiology.

Laser light emerges from both top and bottom of the photonic thruster, keeping it stationary as it pushes outward against spacecraft.
"Our approach to photonic laser propulsion is based on forming an active resonant optical cavity between two high-reflectance mirrors located separately in two space platforms," said Bae. "The breakthrough is in the fact that the laser gain medium in PLP is located within the optical cavity, in contrast to the previous failed attempts at passive resonant cavities, in which the laser gain medium was located outside the optical cavity."
