Steppenwolf:
A couple of points: you claimed that the government can't stop you from burning wood -- OOPS, yes they can and they often do in areas with high or moderate pollution; you claimed, essentially, that it is your greenhouse and you can do whatever you want -- OOPS, aside from government having the right and the power to regulate what you do in your greenhouse, go ahead, use an unknown method to generate heat/power and watch your insurance tell you to go fuck yourself when you have a fire. And given your last comment about not responding to the other points that have been raised, I feel it only appropriate to paraphrase AA by saying that you are just too stupid to pay attention to.
