I like how he refers to it as his "project".

Pouring gasoline straight from the jug...

It's clear he didn't plan on having those kids, either.

I think Archimedes did something like this 2000 years ago.

Isn't destroying currency a crime?

A fresnel lens is hardly a death ray. It can melt steel, yeah, but only at the exact right focal length on a sunny day.

Yeah, those kids are going to the emergency room at least once during their childhood.  Moron.

I like how he says "Don't try this at home"....WHILE DOING IT AT HIS FREAKING HOME!!!
 
2013-03-13 07:31:15 AM  
Built one of these on a smaller scale in 1977. Old school baby! It was fun.

ALL kids end up in the emergency room at some point in their childhood.  Kids play, and kids get hurt.  If you watch any of the other videos on his channel he does a whole lot to include his kids in scientific exploration, and in getting ample and fun exercise (though it's all mostly parkour, which I find kind of dumb, but hey, the kids look like they are enjoying it).

Also his wife is cute.
 
2013-03-13 07:39:51 AM  
Is his death ray for peaceful purposes?

I never went to the emergency room.  Peroxide was the threat that kept me from reporting my open wounds to my mother.  Inevitably, one of my dogs would discover the bleeding and lick it.  Never got infected, so here's an endorsement for dog tongues as wide spectrum antibiotics.

And you didn't?

What kind of helicopters did your parents have?
 
2013-03-13 07:49:36 AM  
Ah, this guy again.

I said this in the candle-out-of-butterstick thread and I'll say it each time he shows up on Fark:

Who is this guy and how can society ensure that people like this are rewarded, protected, and allowed to live out their days in happiness?
 
2013-03-13 07:49:38 AM  

Frozboz: Yeah, those kids are going to the emergency room at least once during their childhood.  Moron.


If you don't give your kids dangerous stuff to play with under supervision, they'll find it on their own.
 
2013-03-13 07:51:55 AM  
I need a fresnel lens.

It was five times for me. Fractured wrist twice, broken collarbone, sprained wrist and some kind of nasty hives. Hell, one time my brother got hurt right after we got home from the hospital and my father had to go back. These days, that would probably end with a visit from the DCF
 
2013-03-13 07:52:57 AM  
Jesus, put a small amount of gas in something else first.  That's pretty f*cking stupid for a smart guy.

Meh. Built this as part of my college thesis project:

1/2" plywood and 2x3 for the frame, skinned with aluminum flashing and aluminized mylar. 5'-6" diameter, 36" focal length. 740ºF in February. ~$120 in materials, two days to assemble.

6 trips and 82 stitches for me.  One concussion from playing tag, tripping and falling into a cornerstone (12 stitches).  Fractured tibia from soccer.  Ten stiches from whipping donuts with a snow machine, then hitting a patch of earth....the machine stopped but I didn't, yet another head wound (the tree was fine BTW). 50 stitches in my hands from collecting aluminum cans.  I ran out of room in the bag and put one can on each finger as I rode my bike (this genius move may have come from the head injuries), a car pulled out of a driveway, I hit it and just about cut off several fingers.  Ten stiched from an earlier time playing soldiers in the woods.  We had a cool fort we had built from whatever scrap we could find and I cut my leg up on some corrugated metal we used as a wall.  In short ALL active and imaginitive children will hit the ER.  Hopefully smarter children will go less often than I did.  You know what, I don't regret any of it.  I had a great childhood.  Active, imaginative and full of fun and friends and stupid dangerous activities.  I would not trade it for the world

Fresnel lenses are awesome. Excellent area to weight ratio. Edmund scientific still sells pretty good sized ones for reasonable prices. I remember back in the day, their selling point in the descriptions in the catalog was something along the lines of "melt asphalt in seconds!". :D

So tell me again why we can't use more solar energy Mr Oil Industry?
 
2013-03-13 08:19:17 AM  
I made one of these from a projection TV Fresnel lens a few years back. My son thought it was cool that we incinerate a block of wood with it.

Got one !  Came off of a scrapped bigscreen I was working on... will have to try it out this weekend... also the lenses from the projector tubes..  fun times...

Close enough.


Image was too big. Anyway, google "solar trough". There are plenty of concentrated solar options in the works and in operation.
Its all really cool stuff, it just has to compete against well established and subsidized options.

I'll also though in a mention for recent break outs in solar panel tech.

Only 740ºF ?  I don't think you get to say meh.

Not in the US at least. It only becomes a crime if you try to use the remains as currency again afterwards.
