- Solar cooking is easy in the summer when the sun is directly overhead. This plastic vinyl sheet has a focal length exceeding 3000mm and produces temperature in excess of 1400˚ F or 760˚ C.

This water lens is a lot larger, need to wait for next season.
I'm a big fan of your water lens! I've done it on a much smaller scale with a picture frame and some saran wrap, but never tried cooking with it ;) Nice work Denise!
Hi Grant, thank you for the cooking compliment! Finally got some sun!
Great work on the "Check Valve" video.

Hi Sean,
The material will fill with rainwater. The last one filled to over 100 gallons before the material tore. While the vinyl is rated as UV resistant it tends to get damaged from 5+ months of exposure. I usually just siphon the water off. This only works in the summer as the sun is lower during other times of the year. Fiber optics do not transfer the light efficiently enough to produce usable heat. I will be making larger fibre in a future video.
Very cool. Wishing you both the best summer ever!
Another great video from my favorite Science couple. Great video !
awesome, denise really developed! :)
thank you for your videos, they are awesome!
I do enjoy your videos.
you are creating a mosquito haven mosquitoes will love you for this project a lot
Liked, I would not have thought it would get that hot
Thank you for the idea. We will do it but not with the water lens as the sun has already made it's move to the south an the focal point is off axis so it would need to me next summer. We have gotten 87" of rain this year so the solar projects have been cloaked by clouds. Denise will be making some videos real soon:-)
Awesome!
We need more Americans like you two.
I absolutely LOVE your videos and had to subscribe!!!! Thank you for teaching us something besides how grumpy a cat can be, or whether it can play the keyboard! :)
That was awesome. Subbed.
Great video. definitely subscribing.
Nice one! So that's what the octagon in your last video was for! You two are not afraid to do things on a large scale, are you! I haven't had fish-sticks in years. Those do look good! Darn it, Denise, now I'm hungry! :)
ur so damm lucky Dan not everybody gets the help on this kind of projects from d wife like u do. u guys please keep posting your videos. Thankssss
Nice work thank's to share
Looking forward to the new vids. Keep the butter churning!
Bravo again
It always amazes me when I remember the energy source is 8 light minutes away! We, as a species, must become solar users to the max! Imagine if the entire global populace came together and designed ta world wide solar grid! The only times power might be hindered due to cloud cover would easily be handled through other alternative energy like hydro, geo-thermal and wind. This water lens is a great example of the awesome power of our sun!
Today, I have learnt that fish-fingers are fish-sticks in US English. Thanks for another good vid, & the language lesson!
thanks for the video !!!
Denise should start a cooking show with this water parabola lens. Suggested title - "Water You Cooking? with Denise Rojas" :D
Thanks 4 share
Cool vid thanks.
Could you put a mirror where your pan was and reflect the light/heat to the bottom of a pan or griddle?
man you havent been following long then have you? go back 3 years or so , and they say this is my xxxxx
Do the results of solar power usage vary for areas of different elevation? I would initially think that Phoenix would make a great place for experimenting, yet I wonder if high-elevation mountains would have better results because of the altitude and thinner air.
Great as usual .... Around 2:09 it got real interesting for some reason.
That is crazy cooking with just sun light, how HOT the cooking oil got; if you have water and the rest of the martial you can survive any place
Very nice video..As you say we don't get much sun in Florida anymore,it's true..Damn cloud seeding is taking care of rainy summers past 5 years..
is there away of having an overflow system ?
Would love to see more complex cooking (like what is seen on cooking networks) using nothing but green power!
I was wondering if you could reflect the sun beam off a mirror upwards towards the bottom of the pan heating it so you wouldn't worry about the hot spot in the pan and not burning your hand. My kids and I love these videos.
Hi what are those special light blocking glasses called? Do you know where I can get some? Thanks.
Torch goggles, not the welding goggles a they are too dark, We have them on our website and you can pick them up on the net from other places too.

clever
I saw you do this a month or so ago & recently tried to use it in a fun cooking competition. It was a major fail because I used the wrong plastic, a plastic bag from a new mattress. I had it duct taped to a metal dog kennel pipe frame & the sun's heat allowed the tape to slip and the ray barley got warm before it became elongated and useless. Had to finish the food on charcoal :( Wish I had taken my time & planned this out better. Now, my wife thinks I'm a real boob. Trying again.
It's kinda messed up when you need welding goggles to cook. ;) Dan: What's this in my fish? Denise: That's part of the fork that melted off. :D
Cool video, guys. Perhaps you could put a 1/4" or 1/2" sheet of metal underneath the pan big enough to shine the light on and leave room for the pan (so the pan is not in the light.) The steel metal plate would absorb all the light/heat. The pan would get the heat from the steel metal plate that it is resting on instead of a direct hot spot. It would be a little less efficient, but the heat would be spread more evenly, maybe?
Looks like Denise has lost some more weight. No bloopers at the end?
Perhaps for cooking you could place a small, raised, circular sheet of dark metal inside a larger skillet so the cooking items will be equally spaced and out of the focused sunlight.
Why does the plastic not melt?
Solar One in California uses molten Salt to store heat to keep the generator running 24 hours.
In my eye, I see a metal barrel with insulation and molten Lead. Run a copper pipe through it to bleed off heat into steam and then use said steam for a steam engine turning a generator.
I use Lead as an example. It's cheap and hot enough to make steam. But lower than your 1400 F hot spot. Maybe another metal will be more suitable.
Onto something serious.
Have you ever thought of trying to use plastic parabolic as a mold? Maybe using a watery plaster mix or something similar.
you should put fireworks under it haha
I think if you used a mirror and directed the focal point on it and angled it to hit the bottom of the pan it wouldn't burn the food and be great for cooking :)
Please explain to me how, you look five years younger now, than the video four years ago?
If the energy was focused onto a thick slab of iron it would conduct into a skillet just as a stove top burner does. If the light struck the iron for some time before time to cook something it would probably be quite hot for a long time
Sweeeet! :D
Oh, I'm SURE you have a shot.
Breaded Fish sticks = Fish fingers in Blighty!
will sea water work
yes it will if the sea salt is dissolved in the water
There seems to be a bit of a fire/cooking theme going on. Generation of electricity is interesting.
this would be perfect in El Paso i want to build one now
Not possible, they do not like clear water in direct sunlight. Also, the water is changed frequently.

I respectfully disagree you probably used plastic fiber optic the true glass one does radiate the heat and UV. One thing I have not seen you try that is blacksmithing can you forge metal with this power? If so that is huge a truly green blacksmith?
Cant you use copper pipe to heat transfer the energy from the sun to a safe location , sticking your hand under neath the direct light is kind of dangerous
2:08. Thumbs up!
Have you tried to make or show how to make turbines water or wind out of old treadmill motors. Not could you show how.
It would be something, to use water to heat water.
i wish i had that kind of time to fuck around :(
:-)
that is great.. the greatest thing I see here that is smoking is your wife :-) thanks great video...thumbs up...
Dan
As usual you're all wet, lol. Good Job! Buy Denise a barbeque fork before she gets burnt.
could make some nice crispy crunchy bacon with heat like that
bacon and egg sandwiches at your place sounds like a plan :) ill bring the bacon
Fish shaped like stix.. thats just not right
Delicious fish sticks? No such thing!
Holy-Terrorist:>*=* Cool, just 1 danger, dont totch the light direction for not haves burning hand :/
*=* The good idea, to remplace fuel and nuclear power plant with light power plant to boil water for make energy rotor and making electricity :D
*=* Greenpeace!
:-) obliterate
you guy's are doing a lot of green stuff, but eating healthy is lacking, go vegan.....
+HP11208 1000 calories a day and usually beans and brown rice. Not a fast meal option so eggs and fish sticks it is. We use the big parabolic mirror for cooking rice when the clouds are not hanging out.
