But make sure your checkbook is fully charged: At $48,000, the QR5 costs twice as much as a traditional propeller-style unit that generates the same output. It’ll take 18 years to pay back your cost.

24 Month Warranty?
How long will the unit continue to generate electricity if maintained in working condition?

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?
