The fossil fuel industry actually played an enormous role in promoting these technologies as a means to distract environmentalists from the fact that nuclear power was the only power source that ever had the potential to stop climate change. Might be too late for it to help now though.

You know what we need? We need a chemical reaction to fix carbon (from CO2 of course) in the atmosphere. Nothing else is going to "stop" climate change. It's all a cycle, and the only problem we're having is that we don't have a way to convert it back to a liquid or solid (just as long as it's not in the atmosphere).

Sorry, that's just horribly wrong.

How so?

We can remove CO2 from the atmosphere. Plants do it all the time. Photosynthesis

We can also remove CO2 from plant emissions. We have been able to for a long time. A scrubber can do so, but they drive up costs and drive down efficiency. Those things are not cheap to build, run, or maintain. 

The issue is that we are greatly outpacing the rate at which CO2 can be absorbed.  The ocean does, to some extent, provide a buffer against CO2 which would SUPPOSEDLY acidify the ocean over time, but that's a whole other matter.

You shut your ignorant mouth, Teflon is one of the best inventions ever.

I am a Chef, and in my experience Telfon is beyond worthless. Any cook who has HALF a clue how to sear something or saute has zero worries about food sticking. Teflon is for bad cooks and shoemakers. All it does is inevitably peel of and get in your sauce... I hate it

^ I don't think there's a better way to do it than choloroplasts and biology. What needs to happen is we need to leverage genetics and commercial farming to help biology catch up to the industrial scale of the problem. Some research is already going on to adapt algae to the task, but if there's no $$$ at the end it's unlikely to succeed.

I understand that plants do it. However, the problem is as you described, that plants are "slower" than we're putting it out there. It there was an actual technological way to do it, not needing chloroplasts and all that biology, there would be real potential.

I literally just said that there's a technological way to do it.

My position is that we have big useless deserts. These we can shade with massive roof structures on pillars, containing shallow, glassed basins with algae. The algae is fed with air and seawater. The more heavy saline water flows back and pumps the entire system, i.e. evaporation drives the system. The algae is continuosly processed for biooil, which is used for synthetic diesel fuel and synthetic lubrication oils.

These structures will shade and cool large parts of the desert surface. Which means more comfortable habitats. For people, animals, maybe agriculture. Maybe it will rain more. If it doesn't, add some solar towers at intervals.

Scrubbing is unfortunately a method which also reduces the oxygen content in the atmosphere.
We burn fossil fuel, consuming oxygen. Scrubbing removes the resultant CO2, but does not free the oxygen. Unlike photosynthesis.

For useless inventions, I'd like to nominate canned shaving foam.

A lot of you have probably never used anything different? Which is why you assume it's simple and convenient?
It's neither.
Take a stick of shaving soap instead, Palmolive or Tabac. You just wet your face, and use the stick like a crayon on your face. A couple of invisible marks is enough. We're maybe ten seconds in. Apply a wet shaving brush to the face and another ten seconds later you're covered in creamy lather.
Apply your phenomenal Gillette safety razor and you'll be finished in almost the same time as it takes to distribute that canned foam evenly and clean your hand afterwards.

But the real trick, the real beauty, is when you rinse the razor under the tap. It becomes clean. I mean really clean. No little hairs clogging at the corners or between the blades. I really mean it. The razor is rinsed perfectly clear every time. The stuff that makes your razors clog, is really the canned foam itself. It's too slimy and sticky, and dissolves too poorly in water.

The final surprise is the lifespan of your razor blades. I'm not saying anything, you have to experience it yourself.

So why are people using canned foam?
Beats me. Don't say it's convenient because it's not.

What about shaving gel? Expensive. But the brand I've tried was actually good. As good as shaving soap, but maybe a little, little bit more fuzz to spread out and rinse away. But certainly a lot better than canned foam.

@bEVEsthda, about deserts... That's not how it works. You'll finally find water shortage. The temperature isn't the real problem, the lack of water is. http://en.wikipedia...._Desert#Climate
End of Line.

Unless some kinda 'Ice Age' happens (=> change in atmosphere and the direction clouds will go) no significant change in Arizona, Gobi or Great Sahara of Africa will happen.

I'm going to draw the water all the way from the sea. I said sea water.

Oh.

The condom.

That's another good one.

What's the point if all you're gonna do is run away to another country anyway?

I don't get this one. Condoms are very useful. For a lot of different things.

It's silly and useless for all those people who like people paying child support and alimony to people you never wanted to see again.

So lawyers and ex's.

bEVEsthda, if there is one thing anyone should know about me is that 80% of the time you shouldn't take me seriously.

Lucky you. I want people not to take me seriously 30% of the time, but people actually don't take me seriously 95% of the time. Because I'm not a western culture lover (Asia have the best cultures), because my study is in 'human science', because I'm politically not your favorite, BECAUSE I HATE TO READ WALLS OF TEXTS, and finally cuz I have grammar fail like 10% of the time.

I've been gay, transgender, a lawyer, a forty year old virgin living in his mother's basement, a cat and a house-wife who murdered her husband.

But in reality...

I am the Ironman.

And I am the EGGMAN!

It's what I am, THE EGGMAN!

I got the master plan!
