Starting a fire is one of the most rudimentary basic activities that a survivalist/prepper must be able to do. Whether for cooking, warmth, light, or protection – building a fire is critically important.
One method of fire starting I have utilized over the past year is the Fresnel lens. Basically a large magnifying glass – the Fresnel lens can gather the suns light and focus it to a very small and intense spot – generating tremendous heat.
No doubt many of you as kids used a magnifying glass to catch some leaves on fire – this lenses works much the same way.
Why do I like the fresnel lens so much? Here are a few reasons:
- durable and flexible
- simple to use
I have a couple of these in packs just shoved in behind something. So light and easy to carry. Of course – you need sun in order to use them.
I took a few step-by-step pictures to show what they can do…
A couple of my 7″ x 11″ lenses:
Prepared “dry stuff” to burn:
Showing “hot spot” from sun through Fresnel lens on rock:
Hot Spot moved onto tinder – see the smoke?
We have fire!
Super-flexible and durable:
The day I took the pictures the sun was shining bright and it was in the 60’s with a decent breeze. I had no issues at all get a roaring fire going. Obviously there are limitations to fresnel lenses – but they are certainly an option to consider in your preps.
The lenses I like are sized 7″ x 11″ and are super cheap. The are many other sizes available as well – even as small as credit cards.
Love sitting next to a hot fire on a chilly night –
