FRESNEL LENS Flat mirror 250 ft target REDIRECTING SUNLIGHT FOR SOLAR HEATING

This 12 inch flat mirror can redirect sunlight 250 feet - 500 feet to a Fresnel Lens Receiver that can then concentrate sunlight to a target for solar heating and solar cooking. This shows the incredible power of traditional flat mirrors.

Now here's a question. could you do the reverse? in other words, collect the sun in the fresnel lens, directed onto a mirror and redirected to a target? imagine cooking the Talaban with all the sunlight they have over there in Afganistan or Iraq? Sunlight into Fresnel lens onto mirror. easy

@caneywaney Does not work that way,the focal point expands, lens to mirror just bounces. Your target would need to be 20 inches away.

@GREENPOWERSCIENCE I did do it once though. I used a small fresnel lens (sze of a notebook piece of paper) and collected the sunlight through that. Then placed a mirror at the focal point of the lens, bounced the collected light from the mirror to a piece of wood and it started smoking. So I went from sun, to frensel lens to mirror to wood. On what scale could this be reproduced?

Great educational piece of work!

Loved the slow mo of the fly almost getting zapped. "holy sh*t, my ass is on fire..move, move....."

We should not be surprised that the sunlight is still effective 250ft from a mirror, after all it has just travelled over 90 million miles before it hit the mirror. That said it is still worthwhile looking at this as it shows how even shaded areas can receive sunlight for solar panels etc. Excellent demonstration.

Could this be used to direct multiple Fresnel lenses onto a single target? Like a crucible with a main lens on it and one or two secondary lenses using mirrors?

@caneywaney Thats what I'm getting at. I wouldn't pass this along to too many. some could get creativly distructive

Hey I was wondering if this might work to generate heating air . I envision some kind of drum with a vent, then having the lens heat that, and run a hose into the porch of my house in the winter. I would have a small electric far on the hose end on my porch sucking the hot air in. Your thoughts. trying to get cheap heat.

i did this at home my brother held the mirror and i got the lens in front of the mirror but couldentvideo tape it but have one on how to coook go look at my video on youtube

@red7media The sun will be around for another 5 Billion years or something or did you mean when the sunsets? That wont be a problem as it would be very easy to have backup batteries that are also being charged during the day.
