Discussion Mars

Click For Summary

The discussion emphasizes the need for a focused conversation on sustaining human life on Mars, rather than just the journey to the planet. Participants express frustration over previous exhaustive discussions that have not yielded new insights. There is a call for fresh ideas and solutions regarding life support systems, habitat construction, and resource management on Mars. The consensus is that while travel to Mars is a popular topic, the challenges of long-term survival require more attention. Addressing these issues is crucial for the success of future Mars missions.

There is a lot of talk about going to Mars. But not a lot of talk about how to keep the people alive on Mars. I am hoping we can talk about that here.

There were a couple long threads about this recently. Did you see them?

Well, please look. It's not going to be helpful to go through all that again and I doubt anyone wants to anyway. I mean, we seriously beat it to death, both getting there and staying there.

Thread 'E-Bike/Scooter Li Battery Fires'

How E-Bike Battery Fires Became a Deadly Crisis in New York City https://www.yahoo.com/news/e-bike-battery-fires-became-120807964.html Do not bring Li batteries into an apartment or occupied structure. They should be stored in non-flammable structures, either metal, brick or cement/concrete. Don't overcharge batteries. Know what to do if one catches fire. Keep them away from flammable materials. Make sure the batteries are not counterfeit. Be cautious of used or damaged batteries.

Thread '2:1 Pulley Question'

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...

Thread 'Why do all my clocks run slow?'

Hi. I noticed that all electronic devices in my household that also tell time eventually lag behind, except the ones that get synchronized by radio signal or internet. Most of them are battery-powered, except my alarm clock (which runs slow as well). Why does none of them run too fast? Deliberate design (why)? Wrong temperature for quartz crystal? Decreasing battery voltage? Or just a coincidence?
