The advantage of a sunshield is that it is adjustable, you could adjust the satellite to let more or less sunshine through. Other geo-engineering projects don't have this advantage, like pumping SO2 in the atmosphere to cool, or bringing dust in the atmosphere/space.
But the better options are probably carbon sequestering techniques.

To launch this sunshield one would need something like the nuclear pulse powered Orion space ship. One of the best options for space travel.

Two Confirmed, cats.
Odin and Orion - they are from the same litter, and have been together since the big bang.
Rescued them, from the vet.

@ 6:17 RE: Orion and Sirius
As an astronomer, I can tell you that Sirius and the three stars which make up the belt of Orion ALWAYS line up... Yes, they do this on December 24th, but they also do this every other day/night of the year as well. Minor point... but one I felt compelled to make.

But is our view of them always in line with the rising sun? It's supposedly all 5 stars that become aligned on the 24th.

Sirius doesn't "align" with orions belt. Sirius is not a planet and does not move (relative to earth) so it cannot align with anything on any particular day of the year. You also cannot see the Southern Cross constellation from the northern hemisphere.

The life of Jesus of Nazareth certainly needs to be examined critically but this is not a very good example of critical thinking. There are no references and the narrator/writer obviously has no Astronomical training and relies soley on Astrological mumbo jumbo bullshit and his active imagination.

I'm not going to downvote a video that creates so much discussion on the sift but I AM going to call BULLSHIT on this one.

I think Roy Batty said it best... "I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhauser Gate. A Super Duper Cell floating across the Oklahoman Plains. All those moments will be lost in time, like tears in rain... Time to die."


ps. Amazing how a small lake's worth of water can seem so intimidating...

know what's funny?

the poster on my wall, right above my monitor, is the Orion Nebula.

Call of Ktulu was one of my favorites. I think they (Metallica) didn't explore their instrumental sides enough back in the day. Orion also kicks ass.

I think Orion slave girls stole her act.

From his site:

At dawn on July 13, 2006, I started work on an intervention in the Max Feffer tunnel joining Av. Europa and Cidade Jardim. The intervention was through a process of subtraction, scraping off layers of soot from vehicle exhaust built up on tunnel walls to produce images of human skulls.

Police checked us out several times during the early morning when I was working on "cleaning" the tunnel. However, as expected, they could not stop me drawing skulls in the tunnel. "Cleaning" is not a crime. What is a crime is the environmental damage caused by unashamed pollution. And, as also expected, the State did not let the matter rest there. There was only one way to prevent me "cleaning" my way, and that was for them to clean up too. And they did!

The intervention had reached 160 meters when São Paulo municipality started its own first cleaning operation there. However, contrary to my expectation, they did not clean the whole tunnel. What would really have prevented me continuing would have been their removing all the soot, which was the raw material used for the work. The State's intention was to just remove the intervention. They annulled the message by creating a huge clean area and leaving the rest of the sooty tunnel as it was. So this was another crime: censorship! lol...

But since the raw material was still there, I came back with more provocation on August 13th. After working for several nights, the intervention had reached around 120 meters, and the municipal team, complete with traffic department staff and the police turned up to clean the whole tunnel.

After that, every tunnel in the city was cleaned. After finishing work on Cidade Jardim, Rebouças was next, followed a number of other tunnels in the city. But they will all be dirty again in less than 4 months. It would be better to stop polluting instead of cleaning up.

That would be... (coughs) ... factually correct..., karaidl

Have you BEEN on the streets lately, have you SEEN those, those ... THEM

I... I...
have seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched c-beams glitter in the dark near the Tanhauser Gate. All those ... moments will be lost in time, like tears...in rain. Time to die

This info was on the YouTube vid:

NOTE: This is not fan made. The music they used is from The Terminator (1984). The reason is because Orion owned both franchises and that this film was about a robot.

I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhauser gate. All those moments will be lost in time, like tears... in rain. Time... to die.

I need to make room in my schedule to finally play the PC video game I have in storage someplace!
