http://www.quietrevolution.co.uk/index.htm http://www.quietrevolution.co.uk/downloads/pdf/factsheets/QR5%20Warranty.pdf 24 Month Warranty? How long will the unit continue to generate electricity if maintained in working condition? http://www.quietrevolution.co.uk/qr5.htm This makes no sense to me. If the unit will pay for itself in 18 years and the unit will last 25 years, then, the investment is easy to calculate as: 25 minus 18 equals 7 years of electric production over cost. There is no reason to even begin to calculate how well that investment compares to a savings account at 3% interest compounded monthly when there is no mention on the web site concerning the life-time span of the unit. Example: If the unit will pay for itself in 18 years and the unit will last 50 years, then, the unvestment is easy to calculate as: 50 minus 18 equals 32 years of electric production over cost. Why is this important? Imagine your grandparents leaving you with a free supply of electricity for 18 years of your lifetime? How is your imagination working? You can then pay for one more unit for NOTHING. You either squander your grandparents wisdom or you pass it on (with interest) to your grandchildren. Does this not compute? I wonder why?

I can ask many more questions like: What wears out after 25 years? I think it is an important consideration. How about these questions: Does the unit govern the output rate to a minimum in high winds? Does the pay-off rate factor in a total production rate based upon average winds regardless of the ability to utilize or store/sell any excess production? My ability to buy one of these units is a function of gathering credit at market rates. A rough estimate suggests to me that their product targets an affluent buyer. What is the 25 year rate of return on a 401K plan compared to the unit?
