Light energy to Electrical Energy

A photovoltaic module will do this for you. Frequently called a solar cell.

Many calculators have them!

Al

Thanks for the information.

My question is different. I am asking about converting light energy(room Light ) to electrical energy.

Said calculators will operate in a room with no windows lit only by electrical means

Al

You won't get near the energy from whatever you use as you are using to power the light. Why not just use the energy you are using to power the light for your other purpose?

Yes, but what if you keep adding solar cells, eventually you'll get more power than you need to run the lamp. I'm amazed that no one has thought of this sort of thing before. I'm rushing down to the patent office now. Jeff

Is that a "fecesious" reply? I hope so...

(and Yes, I do know how it is really spelled!)

Damn, you noticed. I was hoping to get to the stage where I could attract a few cashed up investors (before the big oil companies shut me down). Jeff

How do you spell facecious?

You generally spell facecious "facetious".

Is that the American spelling or the English version??

Is that the American spelling or the English version??

I believe that the British form of the deliberate misspelling would have been "faecesious". Feces / faeces, foecal / faecal: we've just got to learn to get our s*** together!

facetious is correctly spelled : s-m-a-r-t a-s-s

Dear Key walker:

Here I want to inform you that Seimens company in Pakistan has produced some boards of solar cells that it can produce 12v DC with different powers of electricity and can operate some special type of bulbs for lighting the house and operating TVs.

But thy present problem with this system is the problem of cost which is beyond the capability of most of the people living in the rural areas with poor economical situation. Because the cost per kilo watt of this instrument is high for first payment.

At the moment the idea is to design a system to make the system cheaper so that people can be able not only to use it for the lighting purpose but be able to operate some machinery for production.And I am trying to draw your attention to this side. That is why I have written some extra things which doesn't belong to the answer of the question asked.

And to your kind information I have thought of such methods which may help us in achievement of this aim. From the other side to reduce the pollution of our beautiful environment I think the best way is to find very cheap sources of electrical energy, natural free sources like solar and sea winds, and instrument for the production of this energy to replace most of the present engines working with different kind of fuels which produces CO2 and other poisonous gasses with the engines using electrical energy.

Your intentions are good, but as far as I am aware, the efficiency, even of the very latest cells is low (getting better but still low!) and the prices are still high.....

I personally think that we are probably still 10 to 20 years away from a high efficiency/cheaper product, going by the progress over the last 30 years or so, unless there is some sort of break through....many are working on this....I hope that I am wrong...

May I suggest that using the Sun's energy in other ways may be more profitable at this time. Producing clean drinking water for example....quickly and cheaply of course.....

Also, you appear to be one person, when thousands are working in the same direction for companies around the world, do you feel able to compete in this area?

Dear Andy Germany:

Some thing is better than nothing. If we are waiting for the others may be the others will be waiting for us and this will stop progress and better life. Even all big engineers and scientist do not know many different methods of solutions to all the problems. But they don't stop thinking on natural phenomenon as the others have come to a type of solution for that. This is because we see different solutions to one problem introduced by different people in different time. Or this is why we see different inventions of machines for the same job. Thus no body knows that this is you if you start thinking for some type of solution for this problem you will find the quickest and cheapest solution for this problem without waiting for 20 or 30 years. As you know Electrical energy has a wide range of area for its usage which can bring prosperity to the life of the human being. That is why we always try to find different ways of usage for the same products and electrical energy. Lets not stop people from thinking.

electrical energy

Please just do what you wish, you are right, you could be the missing link for something new in this area.

Its happened before, it could happen again......

How about a big Sun powered Stirling motor with a Generator/alternator attached? That should be vastly more efficient than Solar cells and much, much cheaper. Also there are plenty of good designs available on the web for Stirling motors.....just make it bigger!!

When the sun is not available, you could build a fire under the hot cylinder.

Solar cells do not like a fire and ONLY work in the daytime!!

lol, this is a good read, comic relief.

who is the genius that invenet a twohundred thousand dollar system to produce 2000 dollars work a year? it would only take 100 years to pay for itself. I can here the investors rush to your door.

not to mention the monstrosity would need a house of its own to contain it. lol, too good

I have a welding helmet that is powered this way. Photovoltaic cells charge a small battery that powers the automatic filter dimming feature. Usually welding alone provides enough charge, but if the helmet sits around for a long time, I recharge it from either a fluorescent or incandescent lamp.

HI: Mvel Sky:

There is no doubt that you can do it. To change the light energy to electrical energy there are many methods for that. But depending on the requirement of the, voltage and power, needed you use the selected system. For example for very small voltages and power you can use photo diodes, Photo transistors, photo SCRs and solar cells.

But for getting more power you have to use many of these in series and parallel to get the required voltage and current.

The next System which is widely used only for the solar System is concentrating the light on some water tank or some compressed gas to cause high pressure to be able to operate a small turbine and a electrical generator. But this system requires dense light.

You can convert the house lights back to electrical energy.

I have two feelings here, correct me if I am wrong:-

1) The originator gave much too little information for anything much more than "funny" answers.

2) The Funny answers were great!

Actually the answer to the original question is simply "yes" so you are wrong. However, your answer was very "funny."

Regards,

Keywalker

Thanks, but I can't help feeling that the questioner was after more......

Sometimes I cringe a little when I see a certain type of short question:

"Would it be possible to run an electric motor from the output of a generator, and would it be possible to power a generator with an electric motor?"

I can't help thinking "Oh no, not again!"

....you are not alone!!!!
