r. even if I assume your number (and it probably includes natural gas for heating or other heating bills), you'll need to forecast a 25% rate of saving to justify paying $2000, plus let sat $150/year in access and maintenance fees. In Europe, where energy costs are higher, it might be more economical, but the system's costs and maintenance costs might be much higher. I think that these systems could go into some commercial, industrial and maybe educational markets, but only if the payback are less than three years. Otherwise, it will be an uphill battle, and since that battle is waged by the like of Honeywell and Jacobs Engineering, they will reap the majority of the profits, IMHO. These markets is where ELON has been operating so far, and struggling in, I see no sudden "J" curve evolving there to justify anything like a PS of 25.
