This might not be so bad for Mars either.
If you could grow mushrooms on the waste after extracting the acetone and isopropanol.
Then perhaps create Biochar with pyrolysis and then put that into soils to reduce atmospheric CO2.
If you dumped the biochar into the bottom of the Black Sea, it may stay out of the ecology for a very long time as the bottom waters are anoxic.

He mentions albedo, both deserts and snow. We would have those factors on Mars.
There are not much for clouds on Mars that would help, I believe.
Dust is an issue of course and especially dust storms. But I anticipate that vertical would accumulate less dust, and perhaps be easier to clean.
I have my eyes on this for high latitudes. You may be able to change the progression of fall and spring on Mars with these. As they would not be covered by winter CO2 frost in the same way that the horizontal ground would, early sunshine would warm the springs early and help dissipate the frost both on the panels and the ground. Similarly, it might delay the fall accumulations of frost.
I believe that on Earth the march of evergreen forests to the North, is likely a part of the passage away from ice age conditions for the same reason, but I do not deny the warming from greenhouse gasses as well.
In the video, vertical solar panels along railroad tracks are mentioned. In the USA we would also have our freeway system, but car wrecks may damage them, so it may not be quite as good. Also, the roads are not always snow covered but would reflect some light.
As this is a terraform method by albedo, I well remention it in the Terraform section.

Hydrogen Storage: https://www.msn.com/en-us/money/markets … r-BB1ijuqw
Well, time will tell. My preferred method to obtain Hydrogen or another fuel would be to use pyrolysis on seaweed, and so to produce a fuel and also Carbon materials to include into farm soils. This would take Carbon out of the atmosphere and sequester it for a time. Biochar can stay unoxidized for some time apparently.
But I might prefer a liquid fuel, a Hydrocarbon.
https://www.nature.com/articles/ngeo395 … 0years%205.
Quote:
Carbon sequestration through biochar involves pyrolysis or gasification of organic material in low-oxygen conditions from plant waste 3. The resulting char can be mixed with existing soil, acting as a fertilizer 4 and sequestering carbon with a mean residence time of about 2,000 years 5.
Here are some useful previous posts that can relate to the above:

http://newmars.com/forums/viewtopic.php … 91#p219291
When an ocean farming method dips down to get nutrients from cold water, then those nutrients might carry though into the farm fields, if you put biochar into them.

Void, that is interesting. This year marks (amongst other things) the 200th anniversary of the invention of the telescopic gas holder!
https://en.m.wikipedia.org/wiki/Gas_holder
These were built to contain coal gas, which is mostly hydrogen by volume. The hydrogen was distributed throughout towns through cast iron pipes. Hydrogen leakage was prevented by containing the hydrogen at close to ambient pressure. Coal gas continued to be used innthe UK until the 1970s, when natural gas finally displaced it. If we could do this 200 years ago, but are struggling with the problem today, I strongly suspect that we are on the wrong track. To understand how we should use and store hydrogen today, we couod start by examining how our ancestors used coal gas, given that they are essentially the same thing.

I would not be too obsessed with Hydrogen. Pyrolysis could yield many more manageable fuels.
I think this post has something good: http://newmars.com/forums/viewtopic.php … 23#p218823
The process involves moving a platform with seaweed alternately between sunshine and warm water to cold deep water that has nutrients.
Several uses of the seaweed are possible. First as a food for some creature. Then you might ferment the excreta to get Methane. You might then subject the remainder to high heat to do a pyrolysis, to obtain a fuel and a biochar. Likely the biochar would hold the nutrients that the seaweed absorbed.
The Biochar can be dumped into the ocean or better put into farm soils to beneficiate them and to sequester Carbon.
At several points if you wanted Hydrogen, you might extract it from a Hydrocarbon. It makes no sense to try to extract Hydrogen from water when you could extract it from a Hydrocarbon.
The above suggested method could be modified in many ways.
But the point is you could do pyrolysis with solar concentration or more practical may be electric powered ovens.
You get your fuels to run ICE engines, and also you sequester Carbon, and you also fertilize farm fields.

I like this about a wave power method: https://dutchwavepower.com/#design-philosophy
If you click on "Technology", then there is a video that finally made me understand what they are doing: https://dutchwavepower.com/pages/technology/
Quote:
Dutch Wave Power developed multiple systems of suspensions for the full spectrum needed, from offshore, near shore to even shoreline placement:
deep water locations - off shore
intermediate depth locations - near shore
location at shore (harbour heads, dams) - shore line
I was curious about the potential of wave power:
https://www.linquip.com/blog/wave-energ … dvantages/
Quote:
Approximately 2 terawatts
The energy density of waves along shorelines is approximately 30-40 kW/m of waves, and further out into the ocean, most waves can generate 100 kW/meter of electricity. Less than ½ mile2 of the ocean has the potential to generate more than 30 MW of power, which is enough energy to power 20,000 British homes1. The World Energy Council has estimated that approximately 2 terawatts (2 million megawatts), about double current world electricity production, could be produced from the oceans via wave power2. The theoretical annual energy potential of waves off the coasts of the United States is estimated to be as much as 2.64 trillion kilowatthours, or the equivalent of about 64% of total U.S. utility-scale electricity generation in 20213. Waves could realistically contribute about 10 percent of the world's energy consumption4.

Pulsed Fission Fusion (PuFF) Propulsion System
100kN of thrust at 5,000s to 30,000s of specific impulse is about where in-space propulsion needs to be, in order to colonize Mars in a practical manner. The 1,000t class, wet mass, "large ship" concept that I had in mind, would not require significant additional radiation protection with 100kN of thrust on tap. I was originally planning on a much longer spiral-out time with only 1kN of thrust provided by electric propulsion. If 100kN is achievable, then the large ship would achieve escape velocity in 8 hours 20 minutes. The 500 or so passengers can stay in the radiation-protected center barrel section for that period of time, while the ship clears the Van Allen Belts, and achieves escape velocity.
At the same time, if the work that Dr Buhler's team is performing on propellantless electrostatic propulsion ultimately bears fruit, then we're not going to bother with propellant-based propulsion at all, because the thrust-to-weight ratio of that device is purportedly already over 1, assuming he's not lying. We'll know soon enough after they begin flight testing the device. If their electrostatic asymmetry device works, then it's a technological windfall for in-space propulsion at the very least, quite possibly all forms of propulsion, perhaps finally achieving the promise of electrical propulsion systems. Until exhaustively proven and independently replicated, this is all highly speculative. Until then, fission-fusion pulsed plasma thrusters are sufficient for solar system colonization.
At the same time, we need new physics or a more complete understanding of physics. We know that our understanding of physics is incomplete, so it's time to suspend disbelief just long enough to try some fundamentally new ideas, else we're never leaving the solar system. I don't believe that will be humanity's fate. Eventually interest with the obsessive recitation of what we know, along with the measurement of what we already know, will wane. We'll move on to new power and propulsion concepts capable of providing humanity with the tools we require to finally head towards other stars. At that point, interest in fighting each other over something readily obtainable elsewhere will also wane.
The work of Dr Buhler (Electrostatic force asymmetry) / Dr Shawyer (EmDrive) / Dr Fearn (Mach Effect) / et al, essentially revolves around the propellantless "impulse drives" from Star Trek. We will also need Star Trek's "warp drives" to take us far beyond the solar system. On top of that, someone will need to figure out how to create the "subspace communication" devices to allow for sensing and communicating at superluminal velocity.
