It is possible however a horribly inefficient use of materials.
Venus' atmosphere contains 96.5% CO2, 3.4% Nitrogen and other gasses with the major one being, sulfur dioxide.
The atmospheric pressure is also 93-98 times more than earth, the same as being about 1km underwater. A probe has been crushed 18km above the surface.
Also, the surface temperature is 450 degrees celsius which can melt lead so goodbye cheap radiation shielding.
And the nice fluffy clouds you see are sulphuric acid.
As you said we have such materials but would it not be easier to build something that is efficient?
If you want to build something that needs to get a lot of energy then I would suggest building a massive solar array in space because it will require less maintenance, is a lot more "human" friendly and probably costs a lot fewer resources.
To send the energy back to earth you could:
- Use a laser.
- Save the energy in nano-tube power banks.
- You are currently using a semi-solar solution but if you convert to full solar power you will have a lot more energy to work with.
*semi-solar because the greenhouse gasses which keep the warmth from the sun that in the end warms the water. Also: because the pressure is a lot higher your water will only start boiling at a mere 300 degrees celsius
If you are however determined to build on venus I would suggest:
- Shipping the energy in batteries. You can use the sulphuric acid as an electrolyte.
- You can use the sulphuric acid to react with metals and create hydrogen gas. This gas is extremely flammable and can be used to power a "conventional" engine.
Bonus point:
Theoretically you could terraform the planet to suit your need but this would be very expensive but afterwards, could be used as a hospitable colonization for humans without needing to transport the energy.
