That's a cool dent trick. Makes sense.

THANKS SCIENCE!

YAY!

alleyoop!

I have been looking at solar power alternatives to a lot of the energy being wasted, and this is an interesting one.

How did this happen?

Its a goofy exploit of an understanding that will someday help us live in space, and create an approximation of gravity when our distant progeny drift between the stars.

That would take the boredom out of those long periods doing nothing. They would obviously use electric cars in the space ships because gas exhaust would be too dangerous.

That would be interesting, but i wasnt talking about joy riding around the space ship, i meant that using centrifugal force to generate an approximation of gravity (among other techniques) would be an important part of living in space.

- I was just messing with you. Actually, you are correct that, for the continued health of extended mission crews, a replacement for gravity would be necessary yet possibly unachievable. Without debating exactly what the minimum requirements are, to provide the force (~1-G) necessary without scrambling the crew's inner ear at a comfortable RPM, those ships would need to be quite large. This was proven early in the space programs.

There's been quite a bit of research on human adaptation to rotation. They established the “Comfort Zone” was about 1.0-RPM, where even highly susceptible subjects were symptom free, or nearly so.

So, if I calculated this right, the diameter needed to achieve 1.0G at 1RPM nearly 1600 meters, plenty of room to drive a car.
