How much CO2 this project can suck out of the atmosphere is going to pale in comparison to how much money it's going to suck out of tax papers wallets and divert to  friends and family of politicians

And yet another example of Kalifornia lunacy -

https://www.yahoo.com/news/clocks-running-climate-change-california-120003971.html

Kali is planning to build giant vacuum cleaners to suck CO2 out of the air, mix it with water, and either pump it underground or use it industrially. (Kali still has industry? Really?)

The story says it's "a monumentally expensive" undertaking, which tells you all you really need to know - expensive (make that monumentally expensive) public works projects are a great way to convert public funds into private fortunes. And THAT is the entire point.

That is really cool.Was there some thought the laws of physics were different on another planet?  Poor word choice.

Yeah. Of course it's "possible".

More like the "Challenge of controlled flight with an autonomous vehicle with umpteen minutes of light-lag, in an incredibly thin atmosphere."

Flying on Mars will probably always be second fiddle to rovers, aside from small side missions to look at inaccessible places like cliff sides or something. Due to the thin atmosphere and high RPM's needed it'll drain even the best battery tech fast, and create short flight with a long recharge time.

I suspect that NAA is really thinking about this with an eye towards Saturn's moon Titan, where the gravity is lower, but the atmosphere is thicker than Earth's. And the atmosphere is actually useable as fuel. You just need to carry oxygen, which could be gotten pretty easily from the water ice "rocks" laying around. Or possibly the low gravity and high lift from the environment makes nuclear powered flight possible. RTG's should work really well on Titan, because the "cold side" would be really cold and have the benefit of radiative, and conduction/convection cooling to create a nice thermoelectric gradient due to the atmosphere. Or maybe run a Sterling generator. (Need Birdman!)

IIRC, if your space-suit was light enough, and with some extra fabric and struts, I think it's even possible for a human to fly on Titan by flapping their arms due to the low gravity and thick atmosphere.

In clown world, "boy" doesn't indicate gender any more than does "girl" or "bitch" or . . . . .

What is old is new again.  There is still a law saying the CDC is not supposed to use their budget for gun control studies.

There's also one that says "Shall Not Be Infringed" that they're ignoring

I doubt there are any more shootings now than there have ever been. There are just more of them being reported, advertised, and glorified (gore-ified is more accurate.)

Of course, I guess it is only a matter of time before they invent a form for the dealer to fill out evaluating their opinion of the buyer.

Yeah right

Another question for the 4473 form.  (Another thing for them to never follow up on.)

That is really cool.

The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible.
