Sun Laser

12/05/2007 9:09 PM

This is just a crazy idea I am throwing out to the general audience. If you make any money off it please share it. First does anyone know of any tables on fiber optic transfer of energy. I was thinking of combining a magnifying glass with fiber optic cables and integrating electron gun and vacuum tube technology. I am thinking since a laser needs electrical energy to operate. Mate the lens allowing the fiber optic cables to take the place of a shotgun instead of an electron gun as used in TV's. this in turn would heat filaments to produce heat. The question is how much could be generated?

You're right it is a crazy idea...

Do you have any background in any of this, or are you just smoking that funny stuff?

If you do I would like to see some resource material.

Hello cryptic,

Fiber-optic cables are very efficient transmitters of Computer data and TV/Telephone signals which have been converted into digital pulses.

However, there is not any real useful POWER transfer, just minute quantities of light pulses, which require amplification (in Repeaters), at regular intervals along the fiber-optic cable.

If large amounts of useful POWER are required, it is cheaper and more efficient to transmit light in a vacuum.

That light or heat may be concentrated by mirrors

After all, the Sun's light and heat takes 8+ minutes to arrive at Earth, with only small losses in the direct path, via a vacuum.....

I kind of suspected that what you said was the case. But when I was doing research on solar amplification online there was a guy who claimed that you could transmit enough energy to burn someone and he cautioned people not to do this at home. I wish I could remember the website I got this experiement from. Because with increase in energy we need to need avenues of thought and what was not practical or economical twenty years ago needs to be revisited. Anyway I appreciate your input. If I wanted to more research on fiber optics what website would you recommend. When I came up with the idea I was thinking a magnifying lens can burn paper. Now I know it's not possible to actually dam photons like you do with water but I was thinking of using the inefficiency of fiber optics to sort of soak up the photons which then would be ampified using the electrical energy provided by a wind turbine you would have vacuum tube instead of a narrow focus range like an electron gun on a tv you would try to make it like shotgun beam allowing more of the target area to heat up. Please give me some of your knowledge you start with baby steps and eventually do a mile as an adult.

Hi

What are your bank account details? Just joking...

Ideas which sound crazy today may become real tomorrow. Keep thinking... and sharing your thoughts......

Present optical fibres are not suitable for piping IR (as high optical power), but silica optical cables can transmit KWs of visible light through micronic fibres. So, you probably have to wait until OF technology will catch up with IR light.

I understood your question - as fuzzy as it seems - but I see no future in your concept for power generation.

If you have any experience in tube amplifiers, you should know that your idea of optically heating a filament with IR would eventually just replace the filament power supply which consumes only a fraction of the whole thing. The main power is coming from the HV power supply. Heating the filament is just making a condition for electrons to escape the cathode. They are further accelerated by the electric field between anode and cathode (and other intermediary electrodes) and complete their journey through the external HV circuit. There is the power!

Just creating some free electrons will not generate any electric energy. The process is rapidly saturated due to the cloud of electrons which are repelling any newcomers! Actually this is was a problem in tube design and operation. So, to have electric energy, the electrons have to move.

Lasers are very inefficient IR sources. The most efficient are...incandescent tubes, bulbs, etc. The cheapest is sunlight (roughly 50% of it is IR).

You seem to have some creative potential - but if you want to pursue a career as innovator/inventor, it's better to have solid knowledge of natural sciences. The whole secret is to know how to learn.

Good luck.

Michael

The atmosphere of Mars acts as a CO2 laser using the Sun as a pump.

Of course no resonant cavity so it takes a long distance to have much gain.

To make a sun pumped laser you will need a long pumping cavity with two mirrors parallel to 1/10 the wave of light you are lasing. Overcome the thermal expansion issues and cooling is just the start. Possible but not easy.
