do a blimp with an area measured in sq km is a mean feat. Also venus is in a worse gravitational well position than earth so even if you could make gigawatts of power there it would mostly get wasted getting up outside. And that is after you get past the 1.73% efficiency of this process. icy/carbonaceous Asteroids on the other hand in the same orbit would be gold.
