AQUA WATER LENS PARABOLA 100 GALLONS

This is a follow video to http://www.youtube.com/watch?v=ljiTNRiLh-o

This amazing shape was created by nature, actually 3mil plastic and gravity.

22 sq ft collection area 22 x 144 (inches) =3168 sq inches x 1 inch of rain = 3168 sq inches of rain.

1 US Gallon = 231 sq inches of water, 3168 divided by 231 = 13.72 gallons per inch of rain.

14 inches of rain over the few day period = 14 x 13.72= 192 gallons.

192 gallons x 8.3 (pounds of a gallon of water) = 1593 pounds.

Since it developed a hole before I could measure, I went with the safe guess of 70 gallons.

192 is hard to believe.

Crazy man, Dan.

I've been doing some of the same experiments. I'm pretty sure you would get a catenary surface by doing this. (The shape that a chain assumes when hanging freely while suspended at each end.) Depends what you want to do. You'll get a focal locus.

You can convert a catenary to a parabola by suspending identical weights at multiple points. (Think suspension bridge.) This tends to flatten your lens in the centre and thicken it at the edges, converting your catenary to a parabola.

Not so sure the weight of the water is simply equal to that of a chain. The weight of the bridge on the cables creates a possible parabola vs a catenary of the cables under their own weight. The water may do the same thing. While I would not think this is a 100% perfect parabola, it appears close.

Not to mention it's not a cube so you cannot multiply depth by width to get the volume.

[GREENPOWERSCIENCE]

Actually it may be a whole lot more. After punching the hole, I placed a 50 gallon rain barrel on the ground in the center so the plastic acts as a funnel. We got 5 inches of rain and it overflowed. So if we got 14 inches of rain over the three days I had it collecting for this video, it might be 100+ gallons.

[CFrostyTheSnowman]

No way that is 40 gallons.

[GREENPOWERSCIENCE]

The first video had 12 gallons.

[RupertsCrystals]

70 Gallons is about a quarter of a ton.

You should patent that. Dan's Quarter Ton Ice Cold Shower. ;-)

Dan..how bout some more on the 2 stoke

conversion.....to stirling....I hope....

[Nitrolord1]

lol i was hopen you would stand under it and cot it open.

[Michelle2815CV]

OH MAI GAWD. I WANT TO TAKE A BATH UNDER THAT THING LOL!!!

[WalterMelones]

DAN try setting a massive amount of cristal clear fiberglass resin in the tarp untill it is a near perfect perabola, use that as a templait for some crazy huge mirrors!!!!!!!!!!!!!!!!

LOLOLOLOLOLOLOLOLOL

[Elephantintheroom01]

How often does it rain... why not use a siphon and motor for a project to find out how much energy you could harness from it.

[Kellyswheels]

I was thinking the same about the round frame!

[fuocodifiamme]

really nice vid!

[sab611]

wouldn't it be a centenary curve?

would've been better to show a more complete vid of the idea.

[prodprod]

The idea is to use this thing, plus water to create a really big magnifying lens which could be used to generate solar power the same way that other big (but more expensive) lenses can be used for the same thing.

But if you can ever get it to work, it's only going to be efficient with the sun basically overhead, so it isn't ever really going to be practical.

[peppeddu]

what were you trying to accomplish?

it seems a pointless video
