Could beam the lasers from there. <a href=""http://www.youtube.com/results?search_query=%23starshot"">#starshot</a>",(reply>), @Stuart Morrow These are powerful lasers that will require energy. Lots of energy on Venus. Plus it's closest to earth. Unless we wanted to do this from earth's moon. My only worry is and I do not know how powerful these lasers are going to be. But if we did place these lasers anywhere near earth <b>and</b> we didn't continue ratifying the provisions and as it relates to the outer space treaty. Then, that move may contribute to the initial conditions that would fall in the domain of not favouring a friendly/Star-Trek kind of a future. Confusing? <br><br>On Venus," we could float objects 55 km in the atmosphere. These objects could go in orbit and enter back and float. (They don't have to). And many <a href=""http://www.youtube.com/results?search_query=%23starshot"">#starshot</a> capsules could be launched safely from the orbit of Venus.",(reply>), Wait, what's the connection between lasers and the temperature?
