If they have vegetation with sufficiently good photosynthesis, they figure out how to harvest that, right on their own planet. Trying to surround their “sun” would be overkill.
I would think that if there were aliens in the vicinity that advanced we would have picked up EM transmissions from them by now. I believe there is life out there but one thing that troubles me is why haven’t we picked up their version of survivor or dancing with the stars. Or have we............
Also the best way to find paybacks to liberal cronies.
aliens are probably smarter than humans and are laughing their ass off at us using solar and wind power!
Seriously? There are theoretical sources of power that dwarf fusion, even on the stellar scale. By a LOT. Any truly advanced civilization would have developed one of them...
That massive array of collectors seems to be a nutty idea. If a civilization could build such an extensive assembly, it seems it would require massive amounts of raw materials. Ejecting so much mass from the planet would seem to lessen the mass of their home planet, maybe enough to alter its orbit, it’s weather, it’s time calculations and its long-term prospects. My guess is that all good environmentalists seek skittles-pooping unicorns whose magical waste is an energy source as well as a tasty snack.
There are no Dyson spheres anywhere in this galaxy or any other.
Looking for them is a fools errand.
Wow, I clicked on this thread wondering if Obama had established a subsidy for Illegals to set up solar panels.
Do you think there is enough matter in this whole solar system to actually build a real Dyson’s Sphere??
You want to find aliens, look no further than Congress.
The Dyson sphere would be built from the material of the solar wind, and would also be supported by the solar wind, and so would be very light, sort of like a huge soap bubble.
But the whole idea is stupid, what would they need that much energy for?
I read an article posted here a month or two ago saying that there was a huge scope or scope array planned or under construction in South America (Peru?). This instrument would be capable of resolving mountains on exoplanets.
Well, if you can push optical astronomy that far, why not look for artificial city lights on the night side?
Granted- you're limited to such planets as you can resolve optically, which is a tiny fraction of what's likely out there- but with capability expanding all the time...?
Seems more practical to build your own miniature star and use it for energy than to try to build a shell around an existing star.
Just like dollars and Solyndra, the amount expended to create would never be offset by what you get back.
