Comment Non-commercial use only (Score 3, Interesting) 88

Maybe the legal experts could sit down and work out how to modify licenses (including the GPL/LGPL) to be for non-commercial use only? As long as an entity wasn't making money using FOSS, it could use it just like now. Individuals and non-commercial projects wouldn't be affected. But if you're a business making money using FOSS? Not without paying for it you're not. Yes, this would go against the free-software principles. But principles don't pay the bills every month, and none of these changes would prevent anyone from staying with the existing licenses if they wanted to.

The first thing I think of as a problem would be a company setting up a separate entity that wouldn't make money, just make services available to the company using FOSS to get around the fees. The trick to preventing this would be to phrase the terms so that that entity truly had to pay it's own bills without having the company using it's services pay anything either directly or indirectly. Not even by doing things like providing hosting "free". I'd have to sit down with a bunch of rules lawyers and game out all the ways to funnel money into that entity and how to block them, but what's life without a little challenge?

Firstly, I see you have this notion that martian rocks must all be igneous.

You're not talking about rock, you're talking about regolith.

Depending on where the regolith is sourced

Regolith is not "sourced", it's blown across the whole planet. It's not simply "whatever the underlying strata is made out of".

But, since we are playing 'name the ignorance' in this exchange, your attestation stat perchlorate is 0.5% liberatable oxygen says 'Say i'm ignorant of basic chemistry without saying i'm ignorant of basic chemistry, and am bad at reading too.' The 0.5% statistic comes from the publication at bottom, and is the proportion of the regolith that is perchlorates.

I am the one who mentioned that regolith is 0.5% perchlorates, not that "perchlorates are 0.5% oxygen". *facepalm*

"Saying we'll get oxygen from the 0,5-1% of a poison in martian regolith, rather than bulk ice or CO2, is..."

For God's sake, learn to fucking read.

Washing the regolith to remove the perchlorate is a requirement for *any* other use of that regolith

Which is why you shouldn't be celebrating its existence. It is a problematic contaminant, not a resource.

As you have rightly pointed out, the water ice on mars is more 'frozen mud'. Cleaning the melt is going to be a necessary first step to using it *regardless*. That means either vacuum distillation, thermal distillation, or reverse osmosis filtration. Again, NOT OPTIONAL. This is necessary equipment that you need to bring, regardless.

And this just to get water, the most basic of offworld resources. And all of that equipment (especially the mining hardware itself) requires maintenance and spare parts, which impose more dependencies. And the TRL for use on Mars is low regardless.

You've gone from talking up the ease of operating on Mars to talking it down, yet your self-righteousness hasn't shifted at all in the process.

RO filtration is the least energy intensive of these.

Except, it isn't. 0,5-1% perchlorates. RO typically removes 90-95% of perchlorates. So you're down to ~500ppm. Human safety levels** are in the low parts per billion. You're five orders of magnitude off. Yes, you can purify water that far - and the more perchlorates, the easier - but you're talking an over millionfold reduction. It is not at all trivial. You're talking first RO to get it down to levels where it won't hinder bacterial growth, then bioreactor bacterial remediation, then filtration, then RO, then ion exchange. This is not some little, simple system.

** Plants can tolerate much more perchlorates than humans, but they also bioaccumulate perchlorates of exposed to them, so you have to reduce the water to low ppb levels.

The end products are clean water and perchlorate contaminated mud, and clean mud, with contaminated water.

Viola! *eyeroll*

And your "plan" for dealing with waste perchlorate doesn't just magically produce pure O2 and NaCl in the real world. First off, molten sodium perchlorate, which is what it becomes before it decomposes, is an extremely corrosive oxidizer. Exactly what are you planning to make the furnace out of, platinum? Secondly, you never get perfect decomposition. Apart from residual perchlorates, you have residual sodium chlorate, which is also corrosive, and is a literal herbicide. And your gas stream will contain contaminant chloride and chlorine dioxide, which, news flash, you don't want to breathe.

There is no way on Earth anyone would ever prefer this to just conducting electrolysis on the water that you've already purified.

Over and over and over again he makes the kind of promises that investors use to make decisions and he's clearly lying but he somehow gets away with it. Traditionally doing something like that would be considered investment fraud. But he hasn't cost anyone any real money. Yet.

Lots of promises made and not kept, yet nobody pulling him up on it (from his own party at least)? Sounds like a description of Trump to me...

I will give him credit though he wasn't racist.

His comments about a 2nd Obama presidency included the warnings that the country “could be lost forever” and that another Obama win would lead to “1,000 years of darkness.”

It might just be over the top, but it could equally be read as racist.
