NJ Homeowners Windmill Results in Lawsuits.
A Homeowner in Beach Haven Terrace, NJ is facing a number of legal problems from his neighbors and local government over a 12 foot diameter wind generator mounted on a 32 foot high post in his backyard. This generator manufactured by Southwest Windpower is reported to have cost Mike Mercurio, the homeowner, green ethusaist and seller of alternative power generation for local homes, $15,000 to generate 25% of his power needs, the remaining power comes from 56 solar panels on his roof, about $50,000. The main problem cited by his neighbors is the noise from the windmill. According to the lawsuit, the sound, given off by the mill exceeds that of 50 decibels, considered the level of noise generated by light traffic on the street. The lawsuit also complains of strobing (flashing) shadows caused by the mills spinning blades.
These are the sort of issues that make solar a more viable solution for urban and suburban area. But with Mercurios system, likely costing $65,000, is it financialy benefitial? His gas and electric bills were “as high as $340″ a month, or about $4100 a year. Paying 8% for using a home equity loan, you would be paying $300 in monthly interest for the loan, which would result in you saving nearly $500 in each year if you never payoff the loan. As long as the system lasted 15 years without maintenance expenses, it kinda works, but to pay off the loan within the 15 years. This likely pushes the monthly cost of the loan $700
When you look at an all solar system, that has a 25+ year lifetime, it brings the loan servicing to about $550 a month for a 10 kw solar solution, about 50% more than the cost of power in Beach Haven Terrace, New Jersey

SOLAR POWER ON TERMOPANEL AND PHOTOVOLTAIC IT MEETS VERY UNDER COST
Experimentally I have developed a system of warming of water very special, based on the radiation of the black body. Since you they will know the typical systems they paint negro the panels (which are of copper), because of it the costs are very high. The black color is essential.
Well, simply one day I thought why not paint negro’s water? This way the water will absorb directly the solar radiation and us we avoid the copper.
How I can use the heat was absorb with this black water?. Simple, with a heat interchanger water - water . Then I set to work in this experimental project and it leads it to end.
The scheme consists of a panel of aislapol identical of black face painted, on it 30 meters of transparent hose, glasses to cover the frontal face of the panel, a small pump to re-circulate the black water, a coil of recooked copper and two pots one for the circuit of black water and other one to store the clean water.
The pump makes circulate the black water along the panel, then absorve heat and it transmits it to the clean water, this on having passed for the coil of copper that one places inside the container of clean water. In the experimental installation I uses a photovoltaic panel of 35 watts to give energy to the pump. The pump belongs to 12 volts, consumes 2 Amperes and delivers a flow of 4 liters per minute. In conclusion all the energy used to warm the water was “A” “Solar power”, so much thermal as electrical.
The results are:
With this super-economic panel it is possible to to warm to 60ºC a daily volume of 70 liters of water. Only I use 30 meters of transparent hose (6.000 $ Chilean CLP), if you want to warm up more waters, simply it is necessary to to add more hose tranparente, the pump serves to be used even with 120 meters of length, for which there are no more modifications.
The reservoir of clean water you can place it where it accommodates you, not necessarily in the roof as the typical ones.
The occupied space was about 1 m2, the weight of the panel about three kg. Therefore, if you want , you can cover the complete roof with these panels, it will not affect the structures of roof house.
If they want to implement it in his houses they can contact me, if they have doubts, I will answer them tast.
Bye

Excellent little setup there.
