Escape velocity is 1/5th of Earth's. ....Theoretically.
Orbital speed is lower than escape velocity.

Both are less than 5000mph, though. Right?

The obvious solution is a monorail that you balance upside down on. Since none of it is, as Vman455 points out, real.

Just sayin'.

I don't think the mechanics or the physics are impossible. Achieving silly gear ratios is easy. There's a guy on youtube that invented the worlds most geared down gearbox. I forget the ratio, but a cordless drill wouldn't turn it a full rotation in something like billions of years.

Perhaps the hard part would be creating bearings that can withstand rotating at whatever is required to travel at ~4000 MPH with no air to cool them.

If I understand correctly, inverted in a tube you could experience 1 moon G if you traveled ~8,000 MPH.

Seems there's an awkward transition speed at which you float weightless, unable to steer or otherwise maneuver.

Clouds cut both ways.While their albedo does reflect UV light away into space,they're also part of the most powerful greenhouse effect.
Contrails,thought to cool the Earth,actually hold more energy in,than they reflect out.Also,the water vapor which allows the clouds to form in the first place is part of what's going to kill us.Dry-bulb temperature tells us nothing of 'apparent heat' and what AccuWeather calls their 'Real Feel' temperature.You'd need a sling-psychrometer and a psychrometric chart to 'know' what your local conditions actually are.
If the fossil-fuel industry will simply release their 200-years of research science, that they've conducted to prove the safety of their products since day-one,we can drop the whole climate debate.Obviously,we're talking about the smartest people in the room.And because they're such a good neighbor,we already know that they'd never,ever,even,remotely consider,selling a product which might have the potential to alter the entire planet to the detriment of their neighbors.Right? And U.S.Senators,nor the President would have never allowed them,otherwise,they'd be violating their oath to protect We the People.

I would be more worried if it was the coolest June on record, so at least it's going the right direction.
I think it's these 'outlier' events which get their attention.Anything outside the standard deviation might reflect some 'abrupt' dynamic.

RedPoint covered that when he mentioned going into orbit.

Escape velocity is 1/5th of Earth's. ....Theoretically.
Last night,on PBS's 'Chasing the Moon' documentary of Apollo-11,they mentioned a third-stage burn which took them orbital speed,to 25,000 mph escape velocity,and into trans lunar insertion.

Nate Hagens

Just finished it.Thanks!
I'd really enjoyed his 'Beverly Hillbilly Oil',from a prior lecture.
I equally enjoyed his 'Arguing with a forest fire.'
