it is revolutionary:imagine moving (photovoltaics) to absorb sun lights all the day on every building

this idea is truly revolutionary comparing to what i published before;it is friendly to nature...and saves sooooooooo much sun energy..do you know that we only use less than 10% of suns energy ..imagine what we can do if we got more energy from the sun we can transform it to electicity by (photo cells or photovoltaics)and use it in every aspect in our life....................Iam telling you all this idea worths so much and can make a revolution in our world,specially that we know that oil and gas will soon run out...now you may wonder what is new about this idea??????
well,i designed (((( automatically moving to build an angle of 90 degrees with sun lights as the sun moves)))))small cells to be put on every bulding from the top or even used as decoration around the bulding..they will be flower shaped..so imagine flowers moving with the sun to absorb its energy..not one but sooo many of them

Note:if you go on you will see a picture of the one i made it is great..........

Step 1 Buy photovoltaics

The ability to produce electricity directly from the sun's energy is a revolutionary development. The technology involved in the production of these silicon cells is complicated and the efficiencies are still not even close to those of thermal solar applications, but these unique energy devices are now seen in places as common as the yard (solar powered lights), the highways (solar powered traffic lights and sign lights), and of course the common calculator.

Photovoltaics is the direct conversion of light into electricity. Some materials exhibit a property, known as the photoelectric effect, that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.although they are expensive but what a small coast to save mother earth!!!

I hope you do better in medical school. You are talking about building a solar system which by the way, NOT FRE, is very expensive! Have you devised a "FREE" solar cell made from natural materials? We want an inexpensive or free way to harness the energy from our beautiful planet earth in the form of solar, radiant energy, earth's own magnetic field, etc.

This is not a new concept. They are called solar trackers... They have been in use for years....... For this to be a useful or "instructive" document, it needs to contain plans for making the mechanical or electrical aspects of a tracker, not just a picture of one...

 This is just giving you an idea of what to do, not how to build something. If you need to know how to build it look further on this website or just on the internet. Ninja10 televisions (the newer plasma, big screen one) use alot of electricity, volts, and amps, think about something of a smaller project. But, goodluck, everyone knows Brazil is the bomb along with the rest of this beautiful earth. Once I get out of college I'm going to start building these kinds of things.

What a complet Waste oft Time!!

Everybody has known for decades that folowing the sun gives better output!

If You dont supply any additional info, then You must be in dyre need for shoowing -off!!!

Just a heads up.. This Instructable does not tell you HOW to do this, it is only a vague idea for solar power uses in a city. It is very intuitive for someone who has very little knowledge in this subject, and could point you in the right direction to a homebuilt solution.

What is the substitute for solar panels? Solar panels are very costly.

[TwistedmindZ]

substitute for solar panels is reflective mirror and some water or steam turbine. you have the mirrors reflect on a small tube to heat the water which turns to steam and turns the generator

[matroska]

Check this out: to max out a photo-cell, use a fresnel lens! (Just for knowledge, search here on Instructables the giant Death Ray, the solar one. It really shows the use of a Fresnel lens.) Fresnel lens are cheap lens that can be HUGE (see the Death Ray and check were they get it, you'd be surprised!) and focus all the light on a photo cell. One photo cell replacing 20's..

There is no substitute for solar panels, also I don't know if these are available to you, they are called landscaping solar LED lights, they are small about 2 inches square, self contained, they charge a single NICAD battery during the day, at night the LED turns on, GOD what a waste of energy to produce this crap, but on the positive side you can take them apart, use the panels to make bigger panels and also you get a battery, and some components

[TwistedmindZ]

Isn't that called a heliostat or sun tracker?? I am 100% sure that they have those already.

[arungumber]

I did not find any instructions to build it ,I mean the circuitory and the mechanicals of the systems,so how do we build it and assess the same Arun Gumber

[ninja10]

I have been looking to build a system like yours. I live in the country side of amazon, Brazil. I live about 20 minutes from main city but I think we have to preserve our nature and try to use the best for its preservation. please could you help me building a power system to use the sun energy to power at least a television? could you give me an easy and step by step protocol to build it? many thanks, Dan.

[infoseek]

use motor vibrator to shake the cells and measure the amp on the load "LED / buzzer" well it yelld more output. you can use convex lens to fucos uv and sun radiant to one cell intead of dozen and get the same amp from it

Perhaps this site might help:

Simple shaded-light solar trackers can be found here.

Enjoy

He meant revolutionary compared to his other posts. So this is a step up for him. :)

[Patrik]

Yes, this is a good idea, but it is nothing revolutionary. Solar-tracking panels have been around for ages. However, one of the major problems with photovoltaic panels is startup costs. Adding the tracking machinery increases the startup cost even more, and adds maintenance costs as well (there's not too much that can go wrong with a solid-state solar panel). In the end, it's often more economical to have two fixed panels, than one tracking one. If you can come up with a clever mechanism that is cheap and low-maintenance, it might be worth it though...
