A huge sun shade in space? - BBC Science

[shades2]

If I can put your country into permanent shade... I have some control over you right? Think about that.

[dstechcafe]

why they are planning to put sun shaders?

well 2012-2013 is most destructive solar maximum which coinsidentally at the same time, magnetic field of the earth weakens due to shifting...then BOOM, we're fried.

[Kuingar]

@dstechcafe Solar cycles are not destructive. NO idea where you got THAT from. They're just a cycle which has happened millions of times, and it hasn't killed everything yet.

Use mighty power of nature

In the northwestern Australia, we have huge tides,

huge deserts, huge evaporation and huge dry rivers and lakes.

Huge 12m tidal erosion can revive old dry paleo dormant once mighty rivers, creeks and lakes,

desalinate the country and change deserts to rain forests to provide more rain across Australia

World population is growing rapidly and we need more energy, food, land and water.

ITS ALUMINIUM NOT ALUMINUM

[Lillie1986]

I would so not want to be here when that thing doesnt jump high enough and 20 million tons of aluminum slams into the surface.

[IntellectualAddict]

I didn't see the part where he explained why he's developing new lenses to bend the sunlight. Why not just use currently available opaque materials to block the sunlight.

Wouldn't that me less costly and more efficient at the same time?

Does anyone know?

[CreationPhotography]

global worming is a Global Hoax

[ogfunk187]

I know many worms who go Global worming at the weekends.

[dudev]

@CreationPhotography

How the hell would you know?

[sharinganx12]

anyways, atheist or anything..we ALL have the right to explore our Universe and its functions...

[sharinganx12]

the more clues we understand about Gods power, the more that the limits of our knowledge from God will expand...after all, what we see is what we get...

[sharinganx12]

Well lets skip Venus, with TIME the sun is getting old and will eventually turn into a red giant, consuming all the inner planets (possibly Earth and Mars)...although Mars could be our only hope..

[sharinganx12]

OH I see, so we need air pressure..so decreasing the air pressure on Venus would make it breathable?

[sharinganx12]

also might it be possible to bombard Venus with molecular hydrogen (H2) gas? Because I was thinking the hydrogen might bond with the oxygen in the carbon dioxide, and would yield carbon by itself. Or would it make it worse? Same thing with those sulfur dioxide clouds that if we bombard them with hydrogen would it yield water and sulfur?

[sharinganx12]

We'll leave the farmlands alone, we need to restore the broken rainforests like the one in Amazon. Also, volcanic soil is very rich and fertile, necessary for plants and since volcanic eruptions release CO2, the plants would LOVE IT! The more CO2, the more plants we need to maintain our CO2/O2 cycle...

[sharinganx12]

how about we donate some of the CO2 from Venus to Mars? oh well only IF there was an actual real way to do it. Although there might be a way, I'm thinking about those bigger darker sunshades which would condense Venus' CO2 into dry ice. We could collect the dry ice and let it evaporate on Mars. But then again, my crazy imaginations...

[sharinganx12]

No, listen you all...since plants love CO2 then we should just brim the earth with plants and trees to convert that CO2 into oxygen, simple! No need for such drama...Think of how 'green' the Earth would be if 50% of it at least, would be covered with plants and such (including seaweed and water-based plants)...now THATS alot of oxygen we could cheat off of..and oxygen might restore the ozone layer perhaps?

[sharinganx12]

you know, why don't they use the sun shade on Venus instead? it might make the atmosphere rain but its worth it...

[livinginoneness9]

thats awsome only thing is when we get into global cooling theyll start having to make a greenhouse effect

[Mahmhn]

This sounds like the LHC pointing upwards!

[DragonCuber]

A giant sun shade is a WASTE, it's only prolonging Global Warming, we can't get rid ,of the CO2 in our atmosphere by using it and the climate underneath is will change HORRIBLY. Whoever thought of this idea is an idiot!

[kamikakushii]

Would this be similar to a rail gun..?

[sphinxrising58]

Think about it, a very lund clap of thunder at the summit of a mountain, avalanche city baby for whatever is down below.

Some scientists or wannabe scienctists are so smart that are actually quite stupid, as is the idea of a some giant sun shade in space, rolls eyes.

[MillionsofBees]

FUTURAMA

[kelltiozim]

Is yur name Earl Erlien? That's an interesting idea, could we send terrorists n illegls to the moon that way?

[dogmansheepfart]

lol and tourists

[Erlien9]

what is this good for anyawy

[Allyredstar]

To first try it on nasty neighbours!

[DeanoPiano]

Could work but then you have weather and wind resistance as well as velocity entering space, how can you regain control of your speed when you break through the atmosphere at such strong or slow acceleration? time will tell for this or further experiments.

[Critter145]

My first thought is:  Don't be daft!

[alitan2003]

he's just talking, they'll never make one lol

[zecnobot]

fascinating

[woodchopper111]

simple campus experiments aka university. universities are where all the research takes places!!!

[Pr0t0sz]

They already use this technology with roller coasters.

[shmookins]

how so? roller coasters use pure gravity as the driving force whereas this one uses magnetic pulses.

[Pr0t0sz]

Yea and so do types of roller coasters for launch like The Hulk and the Superman.

[shmookins]

ah, yes. I forgot about launching the new models. I am old fashioned since they used to pull the carts up a hill and let them go. hehe.

speaking of which, I hear some roller coasters like perhaps the Superman launch as fast as an F16 fighter jet giving you a few Gs. that would be awesome to experience. I really need to go to a good theme park soon. :)

[Pr0t0sz]

Actually I think it was it accelerates as fast as a Porsche 911 Turbo but you may be right.

[Icelandichiker]

Funny

[Rizzerio]

lets look a it this way...we have his great idea how to get off our planet but no idea how to get back...do u realize how long it would even take to attempt to build something like this on another planet.....lets just face it....there is no way of surviving off our planet, no way to get a rain cycle no atmosphere, nothing to possibly protect and no resources to repair broken items, lets just face it....were stuck on this planet, so lets stop wastin our resources on this crap

[ArthurLovat]

Yet! ^_^

[robdukes]

dude, energy = mass. everything can be mutated in this universe. if mankind dont implode itself it can discover technology to build another sun in some distant future

[fizzycan]

err how about a constantly expanding biodome which goes around a planets surface with carbondioxide to let plants grow and get oxygen. we could also try a space station/hotel. these are all viable ideas. we are not stuck on this planet.

[rodney102]

What?? This isn't about getting off the planet, this is about a sun shade.

[rochelimit55555]

it will work definitely, but i think the cloud creator thing is much more feasible.. and realistic

[SCHIZOPHRENlC]

why exactly would we ever need a sun shade?

[SilverFigure]

What most people don't understand that the poor countries do not want money, since money it is just paper, they won't even wipe their butts with it. What they need is gigantic restructuring of their whole society, culture and cityscape, because you do understand how AIDS spreads, right? Now what kind of a politician is going to propose something like that?

[p7811fx]

impossible

[paintballguy113]

wow i cant believe this idea is finally thought of by someone who can do something about it, I thought of this general idea in 5th or 6th grade,

[skreaminjimmy]

More space junk!!! That will save the world(from what?)

I have an idea to save the world- we can start by killing all the people responsible for all this bullshit media (propaganda). BBC CNN FOX NBC AP REUTERS CBS etc etc etc. What a wonderful world it would be. Then the people in our government that fund all these idiot scientist - Then the scientists that take the money for these BS projects. We will be getting along quite nicely but it will take a consorted effort.....

[Sotacap]

You are right, but that's not really the problem.. EVERYTHING IS FUNDED and PEOPLE are DYING of cancer, aids and other stupid things they COULD HAVE cured yet. America spends billions yearly on all the stupid satellites.... people don't really know that, EVERYTHING on earth (radio, mobile) are NOT controlled by satellites, but by earth antenna's .. anyway they test bombs/diseases on other freakin people:| and then give a lie to make more money...

[skreaminjimmy]

There are several cures for cancer and hiv/aids. Any body interested and I'll give you the links. No joke. They who run the media and government don't want to do away with cancer and aids, there is no profit in it for them. Trust me.

[revjimbob]

"Trust me"

No thanks you genocidal paranoid fucker.

[deejaykaye]

Go on then, give us the links that will cure us

[ArthurLovat]

Wow! Killing all the people you disagree with.. You should be locked away! Seriously, think before post!

[skreaminjimmy]

I said nothing of killing those who I disagree, you retard. Kill those who lie for profit while in the process the killing of innocent peoples- Sign me up! Now go do what they told you...

[ArthurLovat]

Yes, I am the retard...

[hollium]

I love the way Americans say 'Aluminum' - it must have been mis-translated somewhere along the line.

[specialkalpha]

How should it be said?

[hollium]

It's aluminium. A lot of the metallic elements end in -ium rather than just -um.

[revjimbob]

In Britain we emphasise the 1st and 3rd syllable and pronounce the 'i' in 'ium' giving it 5 syllables.

[specialkalpha]

Yes I thought that's how the Brits said it and that sounds funny to my yank ears. But as the saying goes, America and England are two people divided by a common language. :)

God Save the Queen.

[iknowthesecretdoyou]

it was originally called aluminum in US. other countries adopted the -ium traditional naming scheme later. but aluminum is the original correct name.

[megamarsvin]

Actually the true original name of "alumium" was coined by a Brit and later modified to "aliminum" by an American and later still modified to "aluminium" by a combination of Brits and Americans to conform with other elements discovered in the same time frame.

Of course simply having been around longer does not make any term more or less correct. If it did we'd still be using "thou" instead of "you". I think it's safe to say it's a matter of preference.

[iknowthesecretdoyou]

well said
