"I don't go screaming "HOAX" just because of it"
Me neither, at least not for the first 6 months worth of honest efforts as to nicely communicate what apparently I alone perceived as being a whole lot more artificial looking than not.
Onto the topic of ENERGY, of which I'm fairly certain the likes of "blackholesun" borgs will automatically attempt to self-destruct before our eyes, as opposed to offering squat worth of equal or better notions.
No matters how advanced or primitive, any survivor upon a planet such as Venus needs access to energy, though not necessarily as much as you'd think.
Here's my energy shot in the dark of surviving their nighttime season in style;
At the absolute worst 10 kw/hr/ET, at best 1 kw/hr/ET, and even less if having become a bit more reptilian or preferably exoskeletal in physiology, as well as cold blooded couldn't hurt, and if possible well acclimated from a little of Darwin's evolution in DNA mutations would certainly have gone a long ways towards getting that artificial energy demand per adapted ET down to as little as 0.1 kw/hr.
If physical space travel were capable of 10% LS (30,000 km/s), chances are that the nearest other community (by a good factor of at least 10) that might have been worthy of offering a Venus class planet is Sirius, and as such we're talking about 90+ years just to get here, while continuously having to expend a great deal of their energy reserves as for fending off whatever particles of anything much over 2 mg, which isn't an option. As for any sort of physical shield to accomplish the likes of fending off larger items of 2+grams while at 10% LS is expecting a survival from those 900e12 joules/s per impact, of which said impact isn't going to dissipate over any second, whereas instead it's going to transpire in a few micro second, thus unavoidable and extremely penetrating to say the least, especially if that 2 gram particle is relatively dense and thereby compact, such as a small amount of iron, which actually shouldn't be all that uncommon.
Thus having to bring along a sufficient supply of energy for this amount of travel and duration of stay on such a remote planet, plus enough reserves as to get back home might not be all that doable. Although, reaching out to a planet of natural geological and atmospheric energy resources seems like a whole lot better notion. Thus as long as the planet they're settling upon is sufficiently loaded with the right sorts of energy alternatives, this group of space travelers need only configure for a one-way energy ticket.
Lo and behold, and unlike Mars or even Earth, Venus has way more than it's fair share of said energy.
The most common and easily available method of obtaining energy is via kinetic extraction, as accomplished from utilizing the vertical pressure differential of 4+bar/km, and of tunneling whatever volumes of said pressurised and good density worth of CO2 as to pass such through a radial power turbine. A relatively small scale of this sort of installation might look somewhat like a cooling tower of perhaps as little as 100 meters in vertical offset, of perhaps 50 meters diameter at the base and 25 meters at the top where the power turbine vents said CO2 differential back into the lower pressure zone that's at least 0.4 Bar less than of the base inlet.
This 0.4 Bar differential doesn't sound like all that much, that is until you do the math on what's transpiring as the inlet volume of mostly CO2 of 65 kg/m3 is directed upward becomes accelerated by a factor of at least 2:1, thus the inlet volume of 1963 cubic meters and of an initial velocity of perhaps one meter per second is transformed into 2 m/s, that's having to exit through the upper 25 meter diameter turbine opening.
That's 127,595 kg/s worth of mass that going to create energy, if you want it or not. Even with 20% conversion/friction losses, that's still greater than 100,000 kg/s that should represent something that's rather hard to pass up, especially if you're having to survive on such a hot and nasty planet. Of course, creating a full blown km worth of vertical offset differential that's taking advantage of the 4+Bar/km, of a structure offering perhaps a 400 meter inlet diameter and 100 meter outlet which might induce as much as a 10 m/s exit velocity, as this is where we're talking about some sort of serious energy potential that's not only there for the taking, but continuously available day or night, and absolutely non-polluting at that.
As for the pint-sized 100 meter tower of power;
KE=.5MV2 represents 50e6 * 4 = 200e6 joules, or a continuous resource of 200 MW. Give that another worse case outcome of producing electrons @25% efficiency and that's merely 50 MW, which should be sufficient for sustaining at least 5,000 individual ETs, or perhaps fifty thousand of those cold blooded exoskeletals.
Besides pressure differentials and volumes of terrific density of what the mostly CO2 medium offers for extracting energy, there's lots of other viable alternatives, that is if those pesky laws of physics work similar to here on Earth. And, with said energy is where all sorts of insurmountable issues become surmounted.
