Oxygen toxic to humans, Thinkabit!? That's straight out of St Peterburg!

I guess you probably believe that crap and are doing your best to breathe as little as possible? Which probably explains some of your thoughtless conclusions, as the brain needs to be fully oxygenated to function at optimum capacity!

Nowhere have I suggested we'd ever remove all CO2 from oceans!

But it's more concentrated there than anywhere, genius!

Repeated compression will liquefy it and allow it to be combined with hydrogen to make all the hydrocarbons we use today, then some! Fuel plastics, fertilizers. And endlessly sustainable without adding a single litre of new CO2 to the atmosphere!

The recovered oxygen can be used with helium in hyperbaric chambers to treat the unwell and keep them safely separated from other patients and health workers. Note. unwell patients are currently treated with your toxic oxygen to aid recovery! And they could use their helium changed voices, to do voice-overs for Disney cartoons?

Built-in UV will ensure the hyperbaric chambers can be thoroughly sanitised between patients.

Meals can be delivered via positive air pressure airlocks to ensure that whatever is in there stays there for a fortnight. And normal bodily excretions can be bagged, stored under the patient in biodegradable plastic and removed from the chambers after a period of patient free UV irradiation.

Ttbn,

Just turning my brain on and re-reading the Straw-Man argument of your first post here ?

Whoever says that infections diseases are no longer global threats ? In the past decade, we've had the Zika virus, various swine and chook flu viruses. In the decade before that, a couple of others, MERS, Alyssa. In the eighties, the HIV-AIDS virus.

Viruses will spring up unexpectedly forever. Some may no more deadly than the flu, to cite Dr Trumpf with his 400,000 dead bodies. Some to come may be more deadly than the current strains of Covid-19. So we can never relax funding and staffing of appropriate health units.

Thank god for scientists with integrity, like Dr Fauci. I hope President Biden appoints him to a suitably senior position, and I'm sure you would agree. He needs to drain every corner of the Trumpf Swampf ASAP.

Toxic oxygen is toxic to pathogens! And the reason why many municipalities use it to dope/saturate their town water!

We apparently cannot breath pure oxygen but as mixtures that are best that don't include nitrogen.

Deep-sea divers, e.g., use it compressed with helium and talk funny in their bathyspheres when safely breathing that particular mixture.

I'd like to trail 5-hour sessions where the pressure is moved up to 3 atmospheres then in the last hour reduced to ambient pressure again.

Apart from blood clotting, folk die from covid by drowning in their own body fluid with lungs too compromised to absorb enough life-preserving oxygen at normal pressure.

Might be a useful therapy in smoke inhalation? Even in field hospitals/ICU's! Where oxygen inhalation by compromised lungs, is reduced for different reasons. Anyhow, if oxygen therapy is good enough for a noble prize winning Doctor? Good enough for me!

On the topic of smoke inhalation, cool burning of one hectare of grassland can, apart from destroying all the beneficial insects that live there, produce as much CO2 as 6,000 cars!

We need to ignore cultural noise and just look at the evidence. This practice was used as an adjunct to hunting and creating a barrier that limited the opportunity for venomous snakes etc to cross and create a danger for those communities that lived in their wikiups.

Fuel reduction is best accomplished all year round in any weather condition including howling gales, with herded animals (goats) and intensive grazing. Rather than cultural noise!

Burnings always create CO2 as well as lifting and removing scarce trace elements which are lost forever. And land that is burnt and burnt for millennia can progressively become virtual deserts.

Desertification is increasing around the globe as the trees are chopped down and "managed" grasslands burned!

Mud-for-brains AlanB just doesn't know when to give up.

//"Oxygen toxic to humans, Thinkabit!?"

Yep it certainly is numbnuts. I gave you a Wikipedia link that explains it. Here's a relevant sentence from the article referring to oxygen's lung toxicity: "Pulmonary toxicity occurs only with exposure to partial pressures of oxygen greater than 0.5 bar (50 kPa), corresponding to an oxygen fraction of 50% at normal atmospheric pressure." So at your 51% by parts @ 1atm it is toxic.

//"Nowhere have I suggested we'd ever remove all CO2 from oceans! "

Nowhere did I say you were going to remove all the CO2. I did say that your plan was to process a sizeable portion of the world's oceans- which is totally unrealistic.
I also pointed out that even if you do remove CO2 from the atmosphere (which was your overall goal by way of extracting it from the oceans) wouldn't do anything of note to the percentage of O2 in the air which you seemed to think that it would.

//But it's more concentrated there [the sea] than anywhere, genius!

That's pure BS. It is patently clear that you have never studied any chemistry. Because if you had then you would know of Henry's Law.
A simple calculation based on this law using just primary school arithmetic shows that the concentration of dissolved CO2 in water is orders of magnitude less than it is in the atmosphere. In other words the concentration of CO2 by parts in the air is way, way higher than the sea.

AlanB it is time for you to realise that you *very little* about the physical sciences and most the stuff you say is totally wrong. So don't demonstrate to the whole world your lack of education by posting stuff that you know nothing about.

Anyway, this rubbish you've posted about CO2 and oxygen has nothing to do with the topic of this thread so I won't be commenting any further about it.

Alan B.,

About 40% of the planets CO2 is held by the oceans. The rest is basically in the atmosphere.

As the oceans warm they will be less capable of holding CO2 and will release it to the atmosphere.

Think of a cold can of coke. When you pop the top it is fizzy. But let it stand at room temperature and it will lose its fizz.

That's how it works with the oceans: cold oceans will take up some of the atmospheric CO2; warm oceans will release the CO2 back into the atmosphere.

A bigger threat is from a thawing permafrost round the Arctic which will release methane into the atmosphere in great quantities.

Methane is 100x more of a greenhouse gas than CO2 but luckily has a much shorter life than CO2.

This news article was posted today and reckons that Australians might be getting short changed by using the AstraZeneca Covid-19 vaccine:

http://www.msn.com/en-au/news/australia/experts-warning-on-scott-morrisons-strategy-for-herd-immunity/ar-BB1cGWvn

Apparently the AstraZeneca Covid-19 vaccine is only 62% effective compared to the Moderna's 94% and Pfizer's 95% which are being used by the US, UK and France.

My understanding of the article is that the AstraZeneca vaccine will arrest the symptoms in most infected people inoculated as a way of suppressing the transmission of the virus but will not be able to eradicate the virus from society and as a consequence Australia will have recurring outbreaks of the virus. Plus apparently a person inoculated with the AstraZeneca vaccine cannot be re-inoculated thereafter with another type of vaccine; so if the AstraZeneca vaccine doesn't work on a lot of people it cannot be fixed with a Moderna or Pfizer vaccine.

Hmmm . . . . . . . . That doesn't sound too good to me. Do others read it that way or have I misunderstood the article?
