Fresnel Lens – Solar Cooking will be happening at Suburban Stone Age

Nov 15 2015 Published by under Fall, Information Age, Journal, Stone Age, The Ages

What do you do when you have a bum shoulder and can’t dig your pond? Why, you buy a death ray on eBay so you can melt glass and cook food, of course!

Let me explain…

A Fresnel lens is a thin plastic lens made of small concentric grooves on one side that focuses light like a magnifying glass. You’ve seen them around – they are those plastic sheets that are used to magnify text, and on a large scale are what’s in a lighthouse to create that beam of light.

When you use a Frenel lens to concentrate sunlight, you take the warm embrace of gentle sunshine and focus it into a face-melting, unholy death-ray. Seriously, if you do it right, that spot of light is strong enough to melt steel. Wow!

So naturally I HAD to have one.

Why? Well, to my mind, this Fresnel lens unlocks a whole wealth of possibilities using only the power of the sun. I can cook, disinfect water, start fires easily, and even go to new places such as metal cutting, welding, and making homemade obsidian. All from the benign power of the sun! Which, by the way, will still be available in the aftermath of a major earthquake.

And so enters a new Era of solar cooking and more at SSA. On the way are two Fresnel lenses, one spot and one linear, plus a parabolic mirror just for funsies. I’ll do my solar cooking and experimenting while my shoulder heals, then go back to finish digging my pond before spring.

(Side note – guess what the pond can also be? An emergency store of water for a disaster. Which I can distill into safe drinking water using the Fresnel lenses and only the sun. A beautiful thing, no?)

I’ll keep you posted!

Siberian Husky Shedding (Blowing) Her Coat

Siberian Husky Coat Harvest

As you know from previous posts, our Siberian Husky Roxy is the family sheep.  We harvest her undercoat and use it to spin yarn and weave hats and scarves.  In case you haven’t seen what it is like when a Husky blows their coat, the video below will give you a taste of the experience.

(VIDEO) How to Build a Fire with Flint and Steel

When camping for the weekend, I love to take the opportunity to practice survival skills.  This weekend I was testing out how to build a fire with flint and steel.  This technique dates back to the Iron Age, and is still incredibly effective today.  Find out how to use flint and steel, along with what works and what doesn’t.

California Tarantulas Are Looking For Love This Fall

california tarantula suburban stone age

The hubby saw this (big) little guy and jumped out of his chair saying “WHAT THE …?!?”

To explain, we have native California tarantulas, and in autumn, the males wander around looking for a hot date. This male somehow wandered into Suburban Stone Age and we found him stuck to the side of the house.

I am sorry to inform you Sir, but there are no tarantula women here for you today.

I put my little friend in a jar and am taking him to a luxurious tarantula resort, the Santa Monica Mountains National Recreation Area. There he can live in bliss and find the big, hairy woman of his dreams.

How to Help Tarantulas

If you see a tarantula on the move in your area, give them a break.  Instead of swatting them with a newspaper, quietly observe these gentle giants.  Chances are you aren’t what they are looking for, and will move along to find a mate elsewhere.  If you need immediate help, call a spider-friendly friend or neighbor to remove and relocate them for you.  Local wildlife centers may also have staff or volunteers who may be able to help you.
