I don't think it would look silly at all with even one cylinder each side unless of course you're going full scale. I had an intercom in the shed at one time during the summer, power when I needed it for my bandsaw and drill press was a generator. Not the greatest setup but worked fine. I can't take air conditioning well so I just open all the shed doors and enjoy the breeze. I'll be putting in baseboard heat and motion lights on the exterior. Have to finish house renovations first and see how much money I have left. [X(]
