DIY Solar Panels

I have questions about making my own windmill I have an alternator our of a Plymouth acclaim, anyway I was thinking about overhauling it to be a more efficient generator. If I do this and it works is it practical to get a simple inverter and pump the AC voltage in my electric meter? It will not produce enough power for my needs but if I do this would it not reduce my electric bill as far as me selling back some power? Also do you need a special electric meter to do something like this?

Your alt. is most likely about 35amps and at 12volts that works out to 420 watts D.C. Then to run that power through an inverter to get A.C. you will have a loss of power which would be about enough to run a couple of 100watt light bulbs, but only as long as the alt. ran continuously and putting out 35amps, which would require a steady wind at least 26mph..

Now I would suggest you check out your local wind velocity for the year to know what the average wind in your area is,I’ll bet you will be very surprised. Most wind generators start to produce power at speeds of 6mph with your alt. that would be about 2 or 3 amps at the most. the power output quadruples when the wind speed doubles till it max.s out around 26mph. All the figures are off the top of my head and not exact.

Sound like a good project that you would enjoy very much, but only for a hobby.

Good Luck with you adventure.

Some day I hope to do my bit for the plane by installing solar panels on my house and getting an electric car.

I hear that conversion car kits are already available. What parts of the standard car are replaced? How much do they cost? What about insurance?

NO JOKES PLEASE, only sincere replies.

The motor is replaced. Batteries and electronic controls are added. The batteries take up a lot of space, because the car was not designed for them

The process is very expensive, and the result not all that great as a car, for anything except carrying a few people short distances. You would do much better to buy a modern car that gets high gas mileage. Good for the planet, good for you. Someday you’ll be able to buy a cheap and functional electric car, but we’re not there yet.

I recently asked a question as seen below and only recieved 2 answers but both were stating that most homemade solar panel guides or build home solar panels are mostly scams..well I have purchased 2 ebooks so far and they are OK and it seems like it is possible, but the ones I purchased are not clear enough…However, I see so many places and forums where people are succeeding at building their own home solar power…If anyone has found any ebooks or resources that can help me build one, I would appreciate it…Thanks for the input…below was my previous question…..
"I just purchased a new home and am wanting to go green a little. I want to attempt and make my own homemade solar panels. I have found so many Do It Yourself solar panel guides and reviews I don’t know which one to use or trust. Does anyone have any recommendations that are tried and true that work and with very detailed on how to make your DIY solar panel? Thanks for the help."…

I had researched this vary same idea for several months on how to build my own solar power because my local home improvement stores wanted several thousand’s of dollars to install their systems. I personally purchased 4 different books and most of them were hard to follow..I did find one that actually helped me create my own solar panels but it ended up costing me about $150 more than stated in the book because I wanted to make it look more professional since I plan on selling my house in a year…here is the link I used to find the book. Good luck!

Home renovation is a process of restructuring or making improvements in your old house. It involves either complete makeover or adding a few things for a better looking house. Most often than not, the homeowners design and implement the changes on their own (Do It Yourself); and sometimes defined by the complexity of the job involved and the budget, c ontractors are also contacted to accomplish the task. There are many warehouses that not only supply the necessary material for but also help the homeowners with DIY ideas and educate them in handling the complexities of the work. DIY may appear to be palatable idea which also radically cuts down the cost of renovation however it is advisable to go for a professional help when the task requires technical expertise and task-specific artistry. The general contractor oversees and manages the entire gamut of renovation work ranging from designing to the work of laying down the electric cables, roofing and removing the debris once the task is complete.

‘Home renovation’ can include anything from mechanical work like wall makeover, that is wall papering, painting walls or installing wooden panels, floor improvement involving new flooring like wood flooring, carpeting etc., roof replacement, upgrading heating, ventilation and air conditioning systems (HVAC), water proofing basements, reducing utility costs with methods like energy-efficient insulation, wood burning stoves, solar panels etc, installing emergency preparedness safety measures etc to decorate the house which includes landscape construction like improvement of lawns, pools, attic etc.

Home improvement can be considered for the economy purpose, making provisions for water storage or installing gadgets that are power efficient or just work efficient like electronic chimney etc. Home remodeling can be simply for comfort reasons too like making arrangements for keeping the house warm in the winters, redesigning in a manner that allows for more sun shine, or making a swimming pool, or gym, or library, or laying gravel in the lawn, recontouring the patio or garden and so on. The extent to which improvement is carried out defines the type of remodeling, which can be partial improvement when instead of the entire home only a certain sections like just the bedroom(s), living room, kitchen, patio, garden and bathroom are being remodeled or damaged or worn out items are replaced with a new or just repaired. Home renovation infuses new life giving a completely different and better look to the house. This kind of man’s desire to combat the ravages of time and taste on the basic lifestyle of man with or without professional guidance come under home renovation.

This is all hypothetical. I am writing a paper about rifles and need to consider the effect of air density and wind speed on the displacement of a bullet. For the purposes of the calculation, I’m using 7.62 x 51 mm NATO bullet, which weighs approximately 9.5 grams. I am also going to hypothetically assume that the bullet is a perfect cylinder, in which case it would have a surface area of 1312.09 mm^2. In an assumed scenario of sea level at 20 degrees Celsius, the force exerted by a 1 meter per hour wind would approximately be 1.21528 x 10^-10 Newtons.

First of all, someone tell me if that’s correct.

Next, can anyone tell me how I can determine what distance the wind will push the bullet?

I have never actually seen a calculation for the deflection of a bullet assuming that the bullet is a cylinder. Normally, the calculation is performed using a parameter called the ballistic coefficient (BC). See reference 1 below.

There are two ways that I have seen people use to model bullet motion in wind:

a) relative motion argument (see reference 2 for more details)
b) gyroscopic argument (see reference 3 for more details)

Both methods give similar answers, but the relative motion argument is conceptually simpler. For a nice summary of all the physical effects on a bullet, see reference 4.

Now let’s look at your solution. Reference 1 gives examples of the typical wind deflections for bullets. Let’s do an order of magnitude calculation. A 7.62 NATO round will have approximately 0.67 inches of deflection at 100 yards for a 10 mile per hour wind (assuming one minute of angle [MOA] equals one inch at 100 yards). Since this round has muzzle velocity of 2500 feet per second ( 762 meters/second), the round will take 0.12 seconds to hit the target. Assuming a constant force on a bullet with constant mass, the acceleration of the bullet can be calculated as follows.

d = 1/2*a*t^2 => a = 2.364*m/sec^2

fWind= ma = 0.022N, which is much greater than the force you list. Of course, I am assuming a 10 mile per hour wind. A 1 meter per hour wind is very low (did you mean 1 meter per second?). So I do not believe that your answer is correct.

To calculate the force on a bullet, I would use one of the references below (like Reference 2) to estimate the effective crosswind induced angle or velocity. Then I would compute the effective force using the method I used above.

Wish I had a better solution for you.

Is it possible to build a water-powered electric generator (or do they sell pre-built ones)? I have a stream that flows through my property year round. It never freezes and has a considerable amount of water flow. It’s about 4-8 feet wide depending on the time of year and 1-2 feet deep … though I could dig it deeper in some areas.

I know they have these kits you can buy to generate electricity from wind. Some even have it so you can sell the extra back to the electric company. This stream has to be able to generate more force than wind.

You need "head" and volume. It sounds like you have volume but you also need to have a vertical differential: the water source needs to be probably at least six feet above the generator for starters. If the stream is higher a ways back, you can run a pipe.
