As per the article, “Theoretically, this technology will allow a spacecraft to reach 1/4 the speed of light in only a matter of minutes, then travel at nearly 174.3 million miles per hour. At this rate, it can supposedly reach Mars in as little as 30 minutes.”

I wonder what the G-Forces would be on the occupants with this kind of acceleration. I’m sure it is above human capability.

Well, "minutes" is a pretty vague term. But let's say it's five minutes. At 5 minutes the average acceleration would be 3x10⁸m/s / (5min * 60 sec/min). Divide that by 9.8 m/s². I get ≅ 2600 g's.

Blackout positive acceleration for most people is 5-7 g's. Pilots, and other trained people can withstand 10-15 g's for brief periods of time. People survive ≅ 100 g's for tenths of seconds in impact crashes, but no one could survive 100 g's for seconds, let alone minutes.

Actually 174.3 million miles per hour is about 1/4000 the speed of light

G Force coped apparently with Cerbonic (whatever) implants.

That was roughly my thought as well, though I'd think that deceleration would be more difficult. Geez, you'd need to start slowing down days in advance.

Piece of dust or two would kind of ruin your day, as well.

Though, drives like these discussed would be excellent to get raw materials to Mars well in advance of any colonists.
