Solar fire-starter

No good if it’s nighttime… Hope you’ve got some dry matches!


#3

Made from aluminum and wights. Scary!


#4

Not new, and way more expensive than these:


#5

I can’t figure out when this would be useful.

A water tight matchbox would be lighter to carry and allow you to start a fire outside of high noon on a warm, windless day.


#6

Or you could, you know, get any of a number of watertight boxes for $10 and a plastic magnifying glass for $5…


#7

I remember virtually the same thing being sold when I was a kid. It certainly didn’t cost $40.


#8

Ain’t got nothing on my one-meter-square Fresnel lens. After all, sometimes the only tinder you can find is scrap aluminum!


#9

Punkin’ instigator!


#10

You call that a solar fire-starter?
In high school, we had an old ~2.5 foot diameter mirror from a spotlight – it would start just about anything on fire… I recall getting a gym towel blazing in the middle of winter.


#11

At $40 a pop you would think they could afford a better hand model. That thumb almost deserves a unicorn chaser.


#12

what is the advantage to this over a lighter weight smaller magnifying glass?

#14

The more expensive and cumbersome alternative to varying combinations of:

A lighter
Waxed wooden matches
A magnifying glass
A small plastic waterproof box


#15

“Uses no fuel?” What about the tinder?


#16

Exactly that device used to be marketed as a solar cigarette lighter. Even then it was a gimmick more than it was useful.


#17

Well golly, I sure know now what I’m not getting anyone for christmas…


#18

No one has mentioned magnesium fire starters yet? Waterproof and last essentially forever (though some have glue failure between the flint and magnesium chunk.)


#19

And even that one is quite expensive. I remember getting one during a horse/ride fair. That was 20 years ago, granted, but it cost about 20 DM (about 10€).

Magnifying glass was my tool of choice for fire starting. I remember going on an orientation outing with a bunch of school kids, and I was the first to get a fire going. I brought 2 pieces of paper for tinder, and the adults were telling me it’s not going to work. When I got it going they surmised that the fact the paper was orange meant it had something in it to make it burn better than normal paper.

So - it doesn’t work on non-sunny days/night, but its way cheaper than $40, and you can use it for other stuff (looking at bugs, fungi, etc)
