SUN - THE ULTIMATE

SOURCE OF ENERGY



A popular concept is that of using the sun for power. Many simple systemcan be solar powered and some can be made from scrap or surplus

materials . Of course , it all depends when and where you need the energy.

It is being used for many purposes. As for an example, it is being used forconverting solar to electrical energy which has many further uses.

There are some application for solar power, that demand raw heat in

quantity. The trick is to collect the heat and concentrate the power so that itreaches useful energy levels.



Sunlight can easily make any metal surface too hot to touch, but it is onething to feel how hot something can get, and another thing entirely to

apply that power in a useful manner.

Here is one simple solar heat engines that can be used for small, hightemperatures applications. it have been made from surplus materials as an

illustration of how simple, cheap, and effective solar power can be.



1.Lenses of various size

2.An aluminum channel frame

3.”Alum alloy” aluminum welding rod

4.A frame of wood

5.Apparatus for measuring focal length6.A square aluminum focus frame



METHODOLOGY

1. Collect thescrap lensfrom thebrokentelevisionscreen

2. ( FRESNEL AND BIASEDLENS)

3. construct the

frame of aluminum of the requiredsize.



“Alum alloy”is used foraluminum

weldingpurposes”



.

Boltsare alsoused for

constr-uctionof

frame.



Install

the lensin thealuminm

frame…..



After installingthe lens,measure

the focal distance .



frame is

madeslightlylarger than focal

distanceso that acrucible or other apparatuscan bekept at the focus.



1..Once we have the center marked, we install a

platform that can be adjusted and used to hold

the work piece at the proper focal point.

2. operate the furnace on a stone or concrete surface.



3. take astandard red brick and hold it at the

focus for about 20seconds.



placing the

brick into theshadows, it canbe observed

that the brick is heated to theextreme…..hot



1.In space (such as on the Moon) this concept can be used to

produce metals for industry, although on a much larger scale.

2. Now, if we are to apply a "biased" lens (one that will notfocus sharply) to a small steam engine, it can operate a small

generator or alternator for charging batteries. The size(takenabove ) of the lens allowed a collection of roughly 750 watts of

power.



1.By using above method we will be able to find metals from core without expending any conventional energy (like ..electrical

.,mechanical power....etc.....).

2.This method can also be used to operate a small generator oralternator for charging batteries. so this is new method for

generating energy.



The moon is like a beach of fine powder. Mining thispowder can be done by bucket-cable-reel

draglines instead of heavy Earth-breaking machinery.

This method can also be used at" moon" to producemetals for industry on large scale.
