GIANT parabolic SATELLITE solar dish cannot blind a pilot

[bccooleycompany]

A piolet wont be 6' from the dish but a bird could be. but the best part, so could flying insects! Dont they pop neet when they fly thru the FP

[staba69]

Could you use that small mirror to reflect hitting point from the big one?

[Zimmermania]

C'mon Rojas... Tell us something relevant. You are stating the obvious here. Been awhile since I visited your awesome channel.... Thin I see this! ...?

[carr869]

Nice mirror. Now what are you goin to do with it? Maybe use it to heat a boiler for home heat or something. You could keep the inside of one of your cargo containers nice and warm. By the way, my little ceiling fan motor that I got from you is awsome. I dont get enough wind back here in the woods where I live. It was fun to make also. Thanks for thevideos. (Tom)

[social3ngin33rin]

cool I think it looks more covered this time :D

[jmosler9]

who the hell thought that it could?

[ieldanth]

@jmosler9 The same people who think a plane can't take off from a moving conveyor.

[onmyown12]

Ok, let's assume that you can possibly blind a pilot. And then what? They'll hit a tree in the sky!? :D

[teddirez]

if a pilot IS 6 feet from your dish there a bigger problems at foot haha

[otakop67]

"If a pilot is 6 feet from my satellite dish, my dish would be the least of his worries."

Thanks a lot, Dan! That line has me laughing so hard, the coffee in my mug was transferred to my wall at great velocity via my nose. Now everything smells like coffee.... which in and of itself isn't a bad thing.

[DarkEnergy725]

I would think a parabolic mirror even at the focal point wouldnt be able to damage a plain because of how fast its moving

[changethecurrent]

Amazing you had to answer this question, glad you did........

[jsmythib]

So easy even a caveman could power A TON OF STUFF! A big stupid dish and an 18th century steam engine...kiss :)

[TheSunergizer]

Dan. Love watching your experimenting. Looking forward to your next project where you get a large steam engine running off of Solar and have the engine turn a regular generator. Large! Few hundred watts!!!!

[47f0]

@homertalk - Aside from the obvious lack of education evidenced by your illiteracy and profanity, where's your ice age evidence? Because the ice, by any standards. seems to be taking a beating lately. Or maybe you've just failed to keep up with the class. Seen the latest Koch Brothers-funded study, done by warming skeptic Dr. Richard Muller? Short summary, since I figure you're only good for a few words, and I'll type slowly so you can understand it: "Oops, our bad. Global warming is real."

[ourkids12341]

love it great vid thumbs up

[Heliusflame]

"Pilot wont be 6 feet from your dish" - unless he is trying to get you!

[jlmknight]

nice explanation

[ryn76]

Dan!! I am really excited to see you put a water coil at that focal point and start pumping water through it!! I so wanna heat my house via radiant floor heat through this method. Get some data points for me so I can learn from your mistakes buddy!!

[noferblatz]

Good explanation.

Thanks Dan!

[c33r0k33]

Okay, so its safe.  When do we get to cook on it?

[druszaj]

@romnsch13 spelled fresnel, pronounced frenel

[47f0]

@druszaj - it's French. As far as I can tell, they randomly ignore consonants to confuse foreigners - or just to irritate them.

[romnsch13]

@romnsch13 West coast nomanclature i guess, (I'm from ca.) But I suppose your right.  I argued with a lighting and stage deco guy over this point some years ago,...... I guess I must have looked pretty stupid. lol:)

[GREENPOWERSCIENCE]

@romnsch13 "s"is silent. GOTO

howjsay ON THE WEB

[connberkshire]

@GREENPOWERSCIENCE lol another guy that doesn't know how to pronounce "Fre(s)nel"

[sevenbegore]

@connberkshire derpty doo "Fresnel lens ( /freɪˈnɛl/ fray-nel)"

[saf271828]

@romnsch13 The guy who invented the lens was French, and his last name is, in fact, pronounced "Freh-NELL," where I capitalized the emphasis.  It's a common mistake, though.

[romnsch13]

@saf271828 Got it, thanks. I need to know this stuff in order to procure needed items.

[N8Dogg1002]

@romnsch13 It's pronounced frennel my friend. No S.

[a10fjet]

ppl have just been conditioned by tv to think its possible, they arent thinking...

[Organikmechanic]

Great informative video, which should dispel the misconceptions about parabolic mirrors. Thanks for sharing.

[arafetkanso]

But this is not a Global warming friendly, isn't ? cause it produce energy over Concentrating light and that will generate HEAT

[georgemargaris]

@arafetkanso Heat is not pro global warming per se. But chemicals that isolate the atmosphere and keep the warmth trapped, so it cant disappear into space... like the glas in a green house.

[arafetkanso]

@georgemargaris it is a good source energy, but compare this : a dish to produce Light\Heat, or a dish to produce 220V-AC , so if you have AC output is greener than light\heat , Thanks

[georgemargaris]

@arafetkanso solar is mostly 12 V anyway. 220 V is really a very dangerous standard for households if you ask me.

But again: Heat is not the problem, heat is necessary for balance. The problem is TRAPPED Heat that cant reflect into space.

[47f0]

@arafetkanso - Uhm, yeah. Great point - except for the part where you're completely wrong. I've got two solar thermal panels on my roof keeping an 80-gallon tank full of hat water for my home. If I tried to power that tank electrically, using photovoltaics, I'd need at least eight times the area of my solar thermal panels at a much higher cost. Solar electric is always going to be less efficient than solar thermal if all you need is heat for water or cooking.

[TheRealXesc]

@arafetkanso It doesn't PRODUCE anything. It takes the solar energy that would normally hit a larger surface, and concentrates it to a smaller point. Had the dish not been there, the exact same amount of sun light would simply have hit the garden over that larger area instead. Look at it this way - it creates a concentrated point of sunlight, but at the same sime, makes a huge spot of SHADE hehind it, which evens it out.

[GREENPOWERSCIENCE]

@TheRealXesc EXCELLENT ANSWER:-)

[JesusDillinger]

@TheRealXesc Have you ever considered just giving up because people are so damned stupid?

[TheRealXesc]

@JesusDillinger I don't think that was very nice of you :)

He was sitting here, and watching a GreenPowerScience video, so all that stupid he couldn't have been ;)

Always remember, that while you may be better at logical thinking, he may be the one that will start your heart, one day during a heart attack - we all have our strengths and weaknesses. The important thing is to know which they are :)

[GREENPOWERSCIENCE]

@arafetkanso a single black car produces 2x the heat this does in a day. A black top driveway=20x the heat stored.

When not in use, this dish reflects sunlight away actually cooling.

[arafetkanso]

@GREENPOWERSCIENCE Great Clarification!!

[IIDASHII]

@GREENPOWERSCIENCE

But how much green electricity does a black car produce? Or a black top driveway. This could exponentially increase the output of a solar panel just outside the focal point, or work a sterling engine at the focal point.

[flexairz]

@arafetkanso The thing doesn't generate heat it reflects heat (infrared) from the sun and concentrates it in its focal point. That heat from the sun was already coming to the planet.

[jnthnbush]

@arafetkanso thanks for that comment, I am starting to understand better why some people don't believe in global warming and green/alternative energy, they just don't have an understanding of basic science.

[jnthnbush]

what box is up there, did you say bat box, like a bird house for bats? If so I want one!

[scubaga]

@arafetkanso It could stop Global Warming by reflecting the sunlight back into space that would have hit the ground. We need to build 100,000,000,000 more of them and get carbon offsets from Al Gore and become as rich as he is.... I gotta go, need to start building those reflectors...

[ieldanth]

@scubaga Eventually, we could turn Earth into a giant disco ball. :D

[Kuploosh]

@arafetkanso Let it also be made clear that too much heat is NOT what causes global warming. It's the greenhouse gasses emitted when fossil fuels are burned that causes global warming. Heat alone doesn't change anything.

[stopcraponutube]

Good topic and I'm currently viewer 777!

[shartne]

you never said where you got the acrylic mirrors at

[PuciferSam]

Joe Carruth has some competition now...just need a boiler and a Genny and you'll beat his sissy 12kw ! lol

Gratz on finishing it. I cant wait to see what you do with it. (5 stars and thumb up as always)

[kistuszek]

@PuciferSam

Link please? Thanks in advance. :)

[PuciferSam]

@kistuszek Joe is in another of Dan's/GPS's video..... watch?v=jTvAL7ty53M

Your Welcome : )

[PuciferSam]

@PuciferSam Joe Carruth is in this GPS's video ...watch?v=jTvAL7ty53M

[FredrikFlintstone]

Cool

[MeNewBee]

What is it that the solar dish does ? HUM!!!

[Tutankhaten]

@MeNewBee

It focuses solar energy for any heat-required function. There are many devices that are engineered to operate on this type of energy. If you watch other videos on this channel, you'll have a better understanding.

[photolodge]

That is a nice dish you made there. I wish I would have kept my old c-band.

[AnnBearForFreedom]

I'd worry if I were a verrry slow flying bird cruising by at 3 feet above the dish, lol

[KyleCarrington]

do you plan employing tracking circuits, Dan?

[MrHorsetail]

Cool dish.

[therealandycook]

PEW PEW PEW

[Vire70]

What about lasers?

[shawn963741]

@Vire70 By the angle of the cockpit to the ground I highly doubt it unless the plane is flying sideways or upside down.

[Vire70]

@shawn963741

Mm... plus, hitting a cockpit window with a tiny laser would be pretty difficult, and forget keeping it stable. I only ask because there's laws specifically about it, and people get all pissy and sentenced to a dozen years in prison etc for doing it, but afaik no ones ever crashed or been really bothered by people doing it.

[Gytax0]

@Vire70 Lasers can blind pilots.

[imjacob5324]

least of his worries, lols
