What would it take to create an artificial Sun?

I want to see an orbiting light warm enough to melt a section of Antarctica say 5k km² in size to make room for several cities. It will be more like a large garden than a planet but it would be a stepping stone to the real thing.

It could start with a light powerful enough to melt less than 1 km² as an experiment and evolve from there.

The Germans seem to get the idea, sort of.

"inexhaustible energy source" (for a really bright ice melting light.)

"black horse" (see "black swan".)

More than the mass of 70 jupiters.


That would cause too many problems. Even if it was possible with current technology. The ice would turn to water that would have to go somewhere. Rising sea level is already a problem. And changing the landscape too much would cause other changes in climate. Maybe some unpredictable. Others maybe catastrophic. Then the mini sun or light or laser would have to be on constantly. Otherwise the cities would be under threat because of the hostile climate. Why not build the cities in safer places? Much of the earth is still available.

That would be the least of our worries.  Nature itself would be thrown upside down in the natural day/night cycle.  Millions of species would probably go extinct.

If it was something direct like a laser maybe it could avoid that? Or if it was something that wouldn't produce visible light? If not, yes. They would go extinct even faster than now. And eventually that would affect us too. Maybe starting with less areas for fishing, etc.

It looks more like BFL's first attempt to build a water-cooled Monarch. HAHAHA I'd say that at the $1.1B (with a B) price tag they can afford a couple "in two more weeks" excuses if the contraption doesn't perform up to specs.

Yeah, this whole hot fusion deal does seem like a bit of a funding scam. How many billions have they soaked taxpayers from various countries over the last few decades?

However, being the armchair scientist that I am I can see that their design looks good. I think they might actually archive a coefficency of power greater than 1.

Lets wait and see what happens when they flip the switch before rushing to judgment. If they state "next week" when it comes time to fire it up then the German taxpayer knows he's been had...

wow too complex
makes me think ::headache::

Why it needs to be in Artartica? It could be on floating space station or underground or planets away from the sun like pluto or sedna. You don't have to create artificial sun. A light bright enough for the plants to survive is enough.

I'm thinking a spot light would work, it could be mounted on a track on the side of a mountain. The light would shine down and melt the ice at the base.

I don't see the water from the melted ice as a problem. It would just be drained off leaving some to form a nice lake.

As for negatively affecting the rest of the world/nature, I can't see a few billion gallons of water creating any sort of perceptible sea level rise. Also, currently the penguin is the only Antarctic resident. The warm environment would allow for thousands of spices to live there.

Why you need another sun? What we have now isn't enough?

What a short sighted question, can you not see the benefit of creating another world? Habitable land is a valuable resource.

Just a small Sun in Antarctica to start but with the intent to eventually create another Earth sized planet.

"And God said, 'Let there be light,' and there was light. God saw that the light was good, and he separated the light from the darkness. God called the light 'day,' and the darkness he called 'night.' And there was evening, and there was morning—the first day." -- Genesis 1:3-5

The claim is that God is our father and what son wouldn't want to follow in his fathers footsteps?

small correction: 13 x jupiters mass would be enough to start deuterium fusion.


they already suceeded in producing a positive net value although it was just minimal and over a very short duration.

Its like destroying your own home, this would certainly cause an increase in the water level which might result in destruction. Lasers are powerful enough to do that, sun would require hydrogen and huge heat for fusion.

The earth as it is is at its best. the nature is balanced by nature or lets say a higher being. Trying to add or remove anything from the earth surface will cause an inbalance which will definitely have negative impacts on us. Melting the ice means that the water stored in frozen form will be displaced and must go somewhere. Nature will balance this by covering some islands and coastal land thus affecting people. let the earth be as it is.

Nature is the higher being, transformed in matter, only mankind is to blind to see that its destroying the god it worships.... depressing...

Title says another world so think about reaching the new world the ones already made for example!

^ He believes the earth is flat. And that we never went to the moon. And that it is a hologram or something. So antarctica is the new world for him. If that makes any sense.


Problem isn't only the ice melted initially. Problem is changing the climate of the region to be habitable. That is a very big change from what it is now. Don't believe that could be contained to a small area where the cities would be. It would have consequences in the rest of the world.

@OP
You're doing it wrong..

Scientists Create Blackest Material Ever Made: Nanostructures Absorb 99 Percent Of Light

The Metalocalypse has begun !

Fascinating, I'll bet that stuff has applications for CCD cameras.

Nano materials would definitely come into play in creating a large and powerful light for this project.

Great link!
