SATELLITE DISH CONVERSION Huge Parabolic Acrylic Mirror Solar Power

[KarasCyborg]

What do you think of those new saws that have two saw blades that run in opposite directions?

[tyreza79]

did you finish working on this,? i would like to see what can this huge parabolic mirror burn:!!

[dchild44]

I wonder if you could make your death ray mirrors round, wouldn't that give a sharper point? I am going to try it with the 12'' mirrors that I have. Thanks

[1foxtrot70]

Dan, I like the idea of using a piece of clear to make your template. The dish that has the channels to hold the panels in place is nice also. In my case I only had a dish with mesh panels that were held in place with large panhead screws thru the mesh it worked ok but not nearly as well as the channel type. I might try to install some sort of channel material to support the panels then recut my panels to fit.

[GREENPOWERSCIENCE]

@1foxtrot70 Thank you for the info

[social3ngin33rin]

Group of fags are passing by >:(

ty south park :) lol

[GREENPOWERSCIENCE]

South Park:-) Vrooom

[sciencoking]

i´m doing a voiceover for most of this video because WROOOOOOOOOOOMMMMM!!!!

[aaronlikesalex]

what the hell is the mask for lol

[Esaw100]

That was a wonderful demonstration. May God bless you and your family.

[GREENPOWERSCIENCE]

:-) Thank you.

[jpmorgan187]

looks tedious and time consuming... find someone with a laser cnc table!!

[NOCNOTCAUGHT]

Where do you get this acrylic? I am in the technological back waters of southwest Florida and seem to have nothing available. Also in your other video you had an adhesive mylar - again where are you getting this stuff? Love your videos - pretty cool stuff! Thanks!

[virgojeep1]

The more teeth on the blade the cleaner the cut.

[stanrock0]

so what about the final item i would like to see what you can do with it

can you boil water?

heat a house ?

bother your neighbor?

i would like a follow up video

please?

[frvfilms]

melt a dang statue during summer.

[jonhunter1987]

That's so cool.

Ever think about getting a big one up in orbit?... I bet a lot of governments would pay a lot of money for you not to aim it at their country... just a thought.

[robertwgardner]

It may be cheaper to put a lot of little ones into low orbit and independently aim each one to reflect to a single spot. Not that I want to give any James Bond super villains any ideas!

[nj4x4fever2]

Fantastic Job on your build, looking forward to seeing the finished product and also would like to see it in action. What temperature range do you think you will get with this at Full Sun?

[Chronic2112]

Interesting. Would be nice to know what the application is for...

[spark300c]

I wounder what will be the energy gathering capacity if the dish

[WildoTheRubberFist]

I like the voice over... lets you focus on the work and better explain it latter :)

[JULYINJULY]

I agree with Wildo, I cannot imagine how you work and explain at the same time, focus camera, plains trains automobiles (lol)

Voice over mix good option. Bet you can do more videos too which is what I like. Learn stuff everyday.

Good job GPS.

[robertwgardner]

The V/O works really well. Sometimes a shorter video is better, providing the same info in a tighter segment.

[johnnecron]

I can see using a hot clue gun on the bottem to spot glue the panels in place so if you ever needed to remove one it would be a breeze.

Dan have you ever considered making an emergency electric generator using a pelton wheel to power a home generator using the citys public water supply as the power source?

the water bill could be cheaper than the electric bill.

[muddymuddymuddmann]

I always wanted to do that with a large dish. That dish can harness a lot of watts. I hope this one is ready on time to cook the turkey.

i respect the clubs but wouldn't a quiet bike be more stealthy? me and an ex club member (enforcer)have debated this he says its like my sound system in old car i blow engine on a status symbol i had a twin 10' in box sub and you could here 4 blocks down it was a caviler if any one cares

i wouldn't have the patience for all that u rawk 5*

[DerkvanL]

You should call it a hobby channel instead of science.

[saturateu]

would like to see the finished product in action!

[Hopefl1]

Hey Dan. What's next a UFO. Thanks for the help on the fresnel lens.

[id0069]

Have you tried using a laminate cutter instead of a saw? Just score it until it weakens enough to either go right thru or break off.

[pinsetter1991]

I'm voicing over becauseZHOOOM!

[zecnobot]

That was funny.

[dchild44]

@pinsetter1991 One of your videos you said that a small satellite dish needs to be sanded before trying to attach mirrors. I cut 1/2 square mirrors and just glued them on the dish with flat latex paint. It has withstood heavy rain and hail without losing a single mirror. The focal point is very small, about an inch. Works very nice.

[GREENPOWERSCIENCE]

@dchild44 Mirrors work but you lose 30% of the potential power based on losing the curve. If you have the mirrors they will work.

[dchild44]

@pinsetter1991 I lined a small satellite dish with 1/2 inch square mirrors, gluing them on with latex paint, dipping each mirror one at a time in a shallow spread of paint. It has withstood heavy rain and hail with no lost mirrors. I did'nt sand the surface first. No prep at all.

[quexalcoatl]

Hey Dan, have you every thought about using mylar as a reflective medium? No idea on pricing, but it could be put between to plexi sheets.

[ABETRMAN]

FIVE STARS*****

PS:

Isn't battery technology the basic hold up

with solar power regarding lights and electrical appliance (getting off of the grid)

[terry735001]

i am the guy the lives in FL with you that is makeing the tracker i tryed emailing you agin but i am guessing i am doing some thing wrong any ways if you would email me back i can send you my info

[whotoinfinity]

Dan, nice job as always! BTW we have the same kind of trash cans... LOL

[icefox00]

have you ever looked at fiber optic lighting? A while back I saw this group using parabolic mirrors and fiber optic cable to have natural sunlight in the darker, windowless parts of houses and stores. A few hundred pieces were bound at the focal point and individual parts came out of the ceiling all over the house, I'll try to find you some pics, it was really cool.

[pubtor]

really huge

[CTOL1]

Dabs of silicone RTV placed in strategic spots would work well. It would adhere to the acrylic and the painted metal frame.

Pretty cool project!

You no doubt told us, but what is the focal length of this "heater"

[spinynorman1982]

That is one aesthetically pleasing solar panel you got there! I was curious about some of the stats though. How much do those mirrors cost? And how long exactly do you think that dish/solar panel will last?

[GREENPOWERSCIENCE]

Each sheet is around $200 and lasts 10+ year estimate. I have 2 pieces laying on my roof from 2001 and they are dirty but still in good shape.

[spinynorman1982]

That is good info. What is your ultimate goal from these projects (that I enjoy so much)? I personally would love to have a house in a major city, that is completely off the grid.

[GREENPOWERSCIENCE]

We are partially off of the grid. $210 bill for our house, my Moms house and our office. Not bad considering we have well water so that is on our electric bill too.

I want to get about 5 KW solar. Stirling or Steam is a nice thought but PV is getting so cheap. I will be using this as a boiler for some super steam in a future video. Also trying to convince family to let me cook the turkey for the holidays:-)

[GUILDGOB]

Oh snap! That would be awesome!!! If you do, are you bringing a Camera to let us watch?

[breezebro]

Don't do it! Don't cook that turkey. It's hard enough to please everyone with a turkey when you cook with perfect conditions and failure to produce a perfectly cooked turkey on Thanksgiving is unforgivable for most.

[sonyxploder]

You should have a backup plan in case your solar turkey goes belly up lol.

[robertwgardner]

Cooking a turkey is hard under any circumstances. Low and slow is best, so that means moving the dish pretty often (every 15 min?). Cook a small bird! If you can hang a big dutch oven to heat up (past the strongest focus!) that would be optimal for consistent temps. Also, ignore Martha Stewart and cook the bird breast side down. Not quite as pretty, but much more succulent!

[GREENPOWERSCIENCE]

I think a urban house off the grid would be a great project.

[robertwgardner]

Absolutely. Consider ammonia in a closed system, as it has a lower boiling point.

I've looked at small scale urban farming as well (rabbits, chickens, worms, fish, garden). I've worked out the biomasses, and a great deal can be knocked off a grocery bill with small animal husbandry that most cities would allow.

[DocterrNick]

Great tutorial!

[GREENPOWERSCIENCE]

Thank you:-)
