Starting a Fire: Fresnel lens

The following article originally appeared over at It can be seen here –

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.

Fresnel Lens

Why do I like the fresnel lens so much? Here are a few reasons:

  • cheap
  • durable and flexible
  • lightweight
  • 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.

For this post I took a few pictures on November 25th to show what they can do – click to enlarge:

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. Click HERE for more info. 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 –
