Get *the* Best Wind & Solar Pak, ever, Easy Earth Energy.... Let me know how you like it!
Looking for some advice to adding to a solar power system. I live in SW Mississippi. When the sun is not out, so to speak we do have wind 8mph to 25mph. Just looking to add economical addition to help charging abilities.

I like to make a micro wind power, can I use a small DC toy motor and attach a small plastic propeller ? If not then what’s can I use ?
It can be done.
A demo I have seen had a propeller about 6 inches across. I have no idea how much wind is required to get any output.
Here is something on line. I expect there are others if you do an google search…

A lot of people say that wind power is ugly but it is a helluva lot betta than cell towas. Sola enagy is great as well. This stuff is betta than oil.
It is too bad that they have not been developed to their capacity. It is a concept whose time has come. Nuclear energy should be another alternative to fossil fuels, however too many crazies block that. But we need to cut our independence to oil so that the oil company’s do no have such a death grip on us.
explain how wind energy works/is used?
describe how the energy is collected and stored??
what are the ways that your energy could be used? what ways is it actually used?
list advantages and disadvantages of using this energy??
what does the future hold for your energy??
No problem.
and is this storage of electrical energy harmful to us in a similar way as power generated through normal measures (such as oil and coal plants – known to cause tumors and birth defects) under high tension cables/power lines? If there is a storage plant for wind energy, what’s the distance from a house that’s considered safe? I’d love to install a wind turbine, so i figured to ask before installation.
First, it is not as efficient to produce any type of electricity in large quantities and then store it temporarily in batteries for later use. The capital cost of installing a large windmill would increase significantly if you also had to have a battery system sized to store the output. In addition, you would lose efficiency when you then had to conert the battery power back to alternating current and the associated equipment to perform that step. Therefore, most commercial or utility owned wind farms are directly connected to the utility grid.
Second, many studies have been performed and none have proved a link between electro-magnetic fields and the conditions you refer to above. But, since you are worried about the possibility, the fields drop off significantly as you move away from the source. While I don’t have the software to calculate exact results, I will simply say that if you are 300 to 500 feet from the nearest transmission line, or 50-100 feet from the average residential line, the fields generated by the line will be significantly less than those that already exist in your house.
Since you are looking for a home installation, there is no way that the fields created by the amount of energy that you produce will even come close to the fields already created in your house. Standing directly in front of your windmill system would be no different than standing in front of your dishwasher.
Also, speaking about a residential system, I read about a good idea the other day that made sense to me. Hook up the windmill up to a buried or insulated water tank. The electricity from the windmill will power the element and heat the tank. Then, the water in the tank is like your battery storage. The water can then be used to supplement the cold water going into your water heater, or, if you have enough wind, you might be able to connect it to a radiant floor heating system. There would be other ways to do this and perhaps better ways to utilize the stored heat.
Check out James Dulley’s website. I’ve included the link below and I think this is where I saw this. He may be using solar energy in his example instead of wind. Regardless, he has other solar and wind ideas that you may find interesting.

visit howstuffworks.com and type in wind energy
Please describe in details how do the whole mechanisms work? How it is developed? What apparatus is required? How the wind turbine is constructed and how it works? Explain me all questions by using 3d figures or images or video if available. Please guide me in the easiest way as much as possible; I want to make electricity for my home by using wind power or wind turbines what should I do? How can I achieve or construct it myself?
It goes back to the concept of a current carrying conductor cutting the lines of flux in a magnetic field, just like any other generator rotated by any prime mover.
1.Which flower part is correctly paired with its function?
A.Sepal: protects the developing seed
B.Petal: attracts animal pollinators
C.Stamen: produces female gametophytes
D.Carpel: produces male gametophytes
2.Where in a flower are pollen grains formed?
A.In the carpels
B.In the anthers of the stamens
C.In the tepals
D.In the stigma
3.Why might wind-pollinated flowers be small and inconspicuous?
A.Because gametes are not produced in the flowers, the flowers can be small.
B.There is no space for large petals because large stamens are needed.
C.Wind can more easily deposit pollen in small flowers.
D.Small flowers don’t need large petals to attract animal pollinators.
4.What is the source of the three sets of chromosomes in the 3n endosperm?
A.Two sets from two haploid sperm and one set from a haploid egg
B.One set from the haploid sperm and two sets from the two haploid polar nuclei
C.One set from the haploid pollen grain and two sets from the diploid egg
D.Two sets from the diploid pollen grain and one set from the haploid polar nucleus
5.When does a new sporophyte generation begin?

I was watching the news just before, and in Queensland they are going to put a few wind power on a farm near a beach, the area that they are putting them there would be a lot of hurricanes, and i thought, can a hurricane destroy them?
If they can take out houses i don’t see why not lol. Those wind turbans have been known to brake during really heavy non hurricane winds.
