This very easy to carry small pocket sized fresnel lens is a great way to make fire.

Yes, I have the Windows Movie Maker on here but I cannot figure out how to load the video to the Movie Maker. I have the videos on the PC but I'm missing something some where when I get to the load data part or whatever is says?

once you click on movie maker, on the left will be some options 1 capture videos 2 edit movies 3 finish movies 4 movie making tips. To load your videos first you must have movies on your computer,like my pictures or my videos, i'm sure you do . in order to load your videos to movie maker go to option 1 capture videos and pick import videos.another window will open with either your pics or videos. click on the video you like then click the import button at the bottom right of window. after you do this it should go back to movie maker with the selected video. Let me know if this helps

I have to go do some running right now but when I get back in a bit I'm gonna give it another go and follow these directions. I know there is a lot more to do with that than there is with just the Youtube editor. Thanks, I'll be back later this afternoon.

Another nice vid, Offtrail! I have suggestion on other tinders to use with the pocket-size fresnel lens: charcloth and tinder fungus! They both work well as a stage-one tinder with the small lens...BUT, you'd need to carry it with you rather than harvest it in the wild. In addition to the fresnel lens, there are other solar concentrators that are fun to use, too. Some of this is surely to be elementary for most forum members; but, this is a "just for fun" add on to OT's OP. Most folks, even as kids, have used "magnifying glasses" (convex lenses) to start fires: convex01 by tjwilhelm148149, on Flickr Fewer folks have used Fresnel lenses -- the flat, plastic lenses made by concentric grooves molded into a flat, plastic plate, as OT described in his video. As OT pointed out, these come in a wide variety of sizes, from small credit-card size lenses, all the way up up to large 3-foot x 4-foot lenses capable of melting a penny in 3 seconds! A good source for the really big ones is www.greenpowerscience.com/SHOPFRESNELHOME.html fresnel01 by tjwilhelm148149, on Flickr Fewer still is the number of folks who have used parabolic reflectors to create a point-focus of solar radiation for fire-starting. This technique may be the one that is the most easy to find and adapt in a survival-type situation. Automobile headlamp reflectors...projector bulb reflectors...and flashlight/lantern bulb reflectors are all examples of parabolic, point-focus reflectors. In this pic, the one on the left was removed from an old, broken overhead projector...the one on the right was removed from an old flashlight: parabola01 by tjwilhelm148149, on Flickr When using a lens, you have two things to be concerned with: keeping the axis of the lens pointing directly at the sun, and keeping the lens at the correct distance from the tinder/fuel. When using a parabolic reflector, you have only ONE thing to be concerned with, keeping the axis of the parabola aimed directly at the sun. The tinder/fuel is automatically at the focal point when inserted into the reflector. I like to use char cloth as my reflector-ignited tinder. The flat-black color makes it more absorbant of the focused radiation. In this pic, you can see a reflection of the charred paperboard glowing red, after being ignited by the focused sunlight: parabola02 by tjwilhelm148149, on Flickr Even the old flashlight reflector, with the rougher and worn reflective surface works well. You can see the red glow on the edge of the char cloth: parabola03 by tjwilhelm148149, on Flickr CAUTION: Once ignited, the char cloth can be HOT all the way through. Rather than pulling it out with your fingers, it's probably safest to poke it out with a stick: parabola04 by tjwilhelm148149, on Flickr

Great post tj thanks for adding this information. Finding an old abandoned flash light might be considered trash. But not to the trained survivor, just like finding an old bic lighter it may came in handy some day
