I'm not as good at the math end as you are but I can see what you're talking about here is almost unheard of. And like you said you're using conservative numbers. And this isn't factoring in grants, tax credits, etc. at all. With Roberts Development talking about LEED certification and being able to factor in increased tax cuts and carbon credits those numbers could increase substantially which would up the incentive for companies to purchase the wind generators. So we're talking maximum these pay for themselves in 5 to 6 years and then turn into actual cash being generated for the company. Now that is one heck of a return on an investment.
