http://www.WindEnergyGuide.net – Super Easy Wind Power Generator For Home Use Getting or building a wind power generator for home use is quickly becoming an attractive option for many environmentally conscious homeowners. Alternative energy sources are looking quite feasible in helping to alleviate both environmental damage and fuel shortage related to the use of fossil fuels. If we manage to develop these budding fields properly, we may eventually wean ourselves off of our reliance on coal, oil, and gas. This will not only stabilize our power generation, but also result in many benefits to the environment as we use renewable, green ways of making energy. Thus, the need for a wind power generator for home use.

These electricity generators are becoming more and more commonplace as people install more of them both on large and small scales. They are machines that can convert the natural breeze-induced mechanical movements into electricity. Thus, they only need this force of nature to produce energy, which is free, essentially unlimited or renewable, and all natural. This basic concept of harnessing the energy all around us is what lies behind any good renewable energy source.

Some background on the concept behind using a wind power generator for home use would be useful to have. Generators work by transforming physical motion, usually rotation, into electricity using strong permanent magnets. Turbines then work on the same essential principle, using natural flows to turn blades, which then produce electricity in conjunction with magnets. Both direct and alternating current may be produced by generators (for AC, the term used is usually alternator instead of generator, but the concept is basically the same). The electricity produced can then be wired to devices for immediate usage, stored in batteries, or even wired back into the power grid for other users.

Most renewable energy sources require a higher capital outlay than conventional fossil fuel power generation. This is because the technology for these new energy sources is much younger and less understood and developed than the older technologies. However, as interest in these sources continues, technological and engineering developments should make costs more manageable. In fact, at present, many systems are already being made available for residential use. This is why it is relatively easy to get your hands on a homemade windmill/turbine.

Of course, harnessing the breeze would not necessarily be efficient for every single home and location. There needs to be, first and foremost, enough available space for the turbine. The amount of space and clearance required varies from setup to setup: some can be mounted on roofs while others need freestanding towers. Remember that the strength of this force of nature would also not be constant throughout the year, meaning other sources must also be used. Getting a wind power generator for home use is still a great, green idea, however.

I have a question please help! I just bought the complete 45 watt solar kit from harbor Freight http://www.harborfreight.com/cpi/cta…emnumber=90599

plus also I got an inverter http://www.harborfreight.com/cpi/cta…emnumber=66817 .

Can I add more solar panel let say up to 200 watt and adding two 12 volts battery using the same charges controller and power inverter?

That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don’t believe the kit comes with batteries, so you would buy whatever size 12V battery bank your power requirements call for.

The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don’t need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it’s a modified sine wave inverter instead of a pure sine wave inverter, so don’t plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.

I see alot of people asking about making their own wind turbines and solar panels, and the only answers they are getting is links to sites that want you to pay for the information/plans. Are their any sites that give you this information for free?

It may not be free but as an example I purchased the guide from http://www.ebooksreviewed.info/earth4energy and constructed a small scale wind turbine (I plan on making a few more as well) and I have to say the design was about as easy as it can get when dealing with something like this. It also provided places to get everything for as cheap as possible. In the end I spent a few hundred dollars for something that sells for $7,000 – $10,000, so I don’t think you’re wasting your money on a guide, you’re never going to make one for free either. The materials alone cost a few hundred and then it takes some time to assemble and if you plan on attaching to the power grid you will need your city/county inspector and the electric company inspector to come out. I hardly think that $50 for a guide is a large cost. If you do plan on assembling one yourself I was pleased with my experience and recommend it. I calculate that I will recoupe my overhead costs within 8-10 months.

Portable Solar Panel Kit is probably any household’s dream – saying goodbye to these irritating and expensive electric-bills. Many people find it hard to believe but this technique can easily operate refrigerators, w. machines, and other popular home-appliances. Read this short report if you want to find out more about how it works.

Quick overview

The ’secret’ behind this unique Portable Solar Panel Kit is about getting one of these special guides that walk you through each and every step on how to easily make Solar-Panels. It is important then to choose the right guide; make sure it uses simple english without being too much ‘techi’, also, does it offer video tutorials, illustrations, and tech support? Anyway, here are some key-advantages and tips that can help you to know a little more about this topic.

What is in it for us?

By now we clearly notice how it brings several key-benefits:

* It is now amazingly affordable like never before.
* Leaves us almost unaffected by any possible energy crisis.
* Made of simple parts/tools found at any local hardware store.
* It is portable and you can take it with you (camping for example).
* Excellent backup to your conventional elec. sys. in case of power failure.

Quick tip

Never wire the power that you produce into the AC breaker-panel by yourself! It is illegal and very dangerous, call a qualified electrician in order to do that.

On the bottom line

If we want to summarize the following article we can clearly say that Portable Solar Panel Kit easily enables us to ‘erase’ our elec. expenses from our monthly budget. One thing is clear – there are many other advantages provided by this remarkable ‘machine’, simply because it offers so many important opportunities. Now that we understand how it works the best tip would be to evaluate it in order for you to enjoy the benefits that it offers.

Traveling against the wind, a plane flies 2100 miles from Chicago to San Diego in 4 hours and 40 minutes. The return trip, traveling with a wind that is twice as fast, takes 4 hours. Find the rate of the plane in still air.

Ok I got this
x+y=4 hours and 40 mintues (line 1)
2x-2y=4 hours(line 2) B/c it took twice as fast
Where does the 2100 miles come in at?

Or did I mess up?

Find the RATE of speed:

P = Plane Speed
W = Wind Speed
P – W = 2100 miles / 4.6666 hours = 450 miles per hour
P + 2W = 2100 miles / 4.0 hours = 525 miles per hour

P – W = 450
P = 450 + W

P + 2W = 525
(450 + W) + 2W = 525
450 + 3W = 525
3W = 75
W = 25

P = 450 + 25
P = 475
The speed of the plane in still air is 475 miles per hour.

Also i wanted to know if 8 AWG is good enough?

It’s not the best, it’s not the worst. Scosche doesn’t inflate their wire size; when they say 5-gauge, it’s actually 5-gauge and not 10-gauge with a thick jacket. On the other hand, that kit only includes 14 feet of 5-gauge and then you have to connect a distribution block and add 9-gauge. 14 feet might not be enough of the thick wire to run between your amp and battery, and 9-gauge is definitely too small. Plus, the kit doesn’t include any thick ground wire. It’s set up to split 9-gauge to two amps, then each amp would be grounded with 9-gauge. It’s not a good kit for a single high-powered amp.

The KLM-K4 kit on this page: http://www.knukonceptz.com/productMaster.cfm?Category=Amp%20Installation%20Kits# is a good value.

8-gauge wire might be enough if you’re using in 4-ohm mode (300w x 2 channels) but not for 2-ohm or bridged mode. You’ll want 4-gauge wire in this case.

you just crash landed on the moon, and you need to survive for 7 days, out of the 15 items, what would be your top 5
box of matches

50 ft of nylon rope
2 .45 caliber pistols
self-inflating raft
ten gallons of water
first aid kit
solar powered fm receiver-transmitter
stellar map
3 100 lb tanks of oxygen
solar-powered portable heating unit
food concentrate
parachute
one case of dehydrated milk
magnetic compass
signal flares

number the list from1-5, 1 being the most important

oxygen tanks-to breathe
water-cant last a week without it
stellar map-you can tell where your going by position of stars
fm transmitter-to send a signal to a base
food concentrate-to eat though you can last long without it

the compass no because the moon has no magnetic field. matches no because they need oxygen where there is none on the moon.a parachute no what for? milk no because you have water.a raft no just no. first aid kid no not important to be top 5.a rope same as pistol.a flare maybe im not sure.a heating unit i dont think you will need that to be in top 5.

and there you go

I have seen a lot of DIY information on making your own solar panels. I have even purchased a couple of them. However, they have not been very helpful in the fact that they either call for buying tons of broken peices and putting them together, or buying each cell and building the frame, and wiring it together. I have a 14′X60′ Mobile home with the flat roof on it. It is in full sunlight 3/4 of every day. I am looking for an inexpensive way to build my own solar panel using the entire roof. I am not looking for the most efficient, because I have plenty of size to work with. I do not have a lot of electrical needs. I am on some medical machines though, if it werent for them I would probably just let the electric go and buy a propane fridge and stove and call it good. I do not want to spend a bunch of money on books either so please no advertisements on where to buy books on this subject. I have very little resources in the way of money or else I would just pay the electric bill, my electric company is 1/4 renewable energy anyway. So if anyone knows of a way to build this, or knows where I can get a book or website for free. please let me know. Thank you,
I have most of what I need. I have the inverter, the regulator and the wiring, what I do not have is the know how on how they built the first ones. I have seen some info. on the web. But not enough to even get me started. I am looking for how they made them back in the 50’s and 60’s when it took massive amounts of space. Because space I have, money I do not. Back then the parts would have costed a lot, but I am betting the parts are pretty cheap by todays standards since they would not be used for solar panels. They came up with the crystals sometime in the 60’s if my memory serves me. I am looking for instructions for the ones before that. I know I can not get more than an 8% yeild, but since I have the room to use, why not use it, if I can get the parts cheap enough to make it doable?

Other than the suggestion of buying surplus/used units that people are removing to get better efficiency – and I would think cities/towns might be more reliable in this area unless you make contact with a reliable club or group in your area (shipping being a factor)
The simple fact is that you are talking a huge area and the cost of solar cells has not come down that much and the labor in assembling the bits and pieces is still fairly high. The high early cost was the very costly equipment and its problems in making pure silicon disks – and there is no way you can do that part economically.
