Could you please read my posts and try to understand it before responding. I said that it was more than twice as efficient than the generator at half load. You will rarely ever run a generator at full load. Anything less than full load decreases the efficiency.
How about letting people speak for themselves. If you don't think this is worth it for you, then just say that. Don't come on to threads and poopoo every idea because of your preconceived ideas on the topic. You immediately said it was less efficient, which shows you did absolutely ZERO research. People would like to discuss new technologies without having someone, a moderator no less, bashing the idea from a position of ignorance.
