Assumptions:

* We have materials that can withstand the temperatures/pressures/acidity of Venus.
* We can get to Venus and back reasonably easily (NASA does shuttles every 3 months).

Here is Venus:

From what I know, [water boils at 100 C](http://en.wikipedia.org/wiki/Water) (at sea level on Earth) and the [pressure on Venus at 40.5 km is the same as on Earth at sea level](http://www.astro.wisc.edu/~townsend/resource/teaching/diploma/venus-p.gif). Finally, the [temperature on Venus at ~40 km is 100 C](http://www.realclimate.org/wp-content/uploads/clouddeck.jpg).

So would this work:

Water is heated to gas, goes through turbine and makes electricity and then gets pumped back up and cools to liquid and then the cycle goes again.

Would this create energy without using more than is required?

Next question, how would we get that energy back to Earth? I have a semi-idea:

* Incredibly powerful lasers, onto solar panels on the Earth.

	+ These could shine either visible light, or maybe a wavelength on the electromagnetic spectrum that doesn't get absorbed by the atmosphere.
