i think you just ran out of ideas for things to do with a fresnel lens, dan. That, or you ran out of money to spend on your super-awesome ideas.

What effect would more mirrors have? I wonder if they would reach the same focal point

you’re just so awesome man, thankyou for all you go through. you have certainly done your job for humanity

I have purchased two fresnel lens from you on E-bay. These are great tools to cook food using solar energy for a situation where the SHTF. I keep the small one in my back pack. It is 12 inches by 12 inches. It probably won’t cook food in a cooker, but it should be able to start a fire using good tender. The big monster one I bought from you should cook a pot full of pinto beans easily.

very very cool,, great video, and thumbs UP!

@toamaori I don’t see why they would not.

Was the round circular Fresnel lens cut from one of your larger square lens ?

This reminds me of Arcemedies death ray. but on the other hand this is awesome thinking outside the box. You need funding for these projects. You could change the world.

I hope people understand why you demonstrated this using reflected sunlight. Show how good it works off a solartube next. If ya can? They ain’t cheap.

@343HFD Dan is working with the concepts that can make plenty of fresh water for everybody and end our energy problems. Not run of the mill tree hugger stuff about solar panels and windmills. He covers the standard stuff too, but he goes beyond that. If you had any experience with this stuff, you’d realise how stupid you are for labelling him a simple tree hugger.

Why would you want to profile Dan Rojas?

@AlexGrim, hey bud srry I was in a bad mood when I posted that. I am accually all for this kinda research because sooner or later we ARE going to need it! Sorry again!!

I really like your new closing music. Much better than the old one!
April 29th, 2010 at 7:48 pm
can you use optic fibres with a fresnel lense to take heat into the house?
April 29th, 2010 at 10:01 pm
Why not redirect the concentrated light after it hits the Fresnel Lens? So it would act more like a lazer pointer. Burn baby Burn.

We should not be surprised that the sunlight is still effective 250ft from a mirror, after all it has just travelled over 90 million miles before it hit the mirror. That said it is still worthwhile looking at this as it shows how even shaded areas can receive sunlight for solar panels etc. Excellent demonstration.

Nice. But not sure how you could use this. The Sun is continually moving in relation to the Earth. You’d need a tracking mechanism on the mirror mount to continually adjust its angle if you wanted to apply this in any useful way for more than a couple of minutes at a time. Tracking mechanisms require power, and electronic sophistication beyond the average DIYer, so the whole thing starts to get much less simple …

@343HFD Thanks for posting that. Need more of that sort of peace-keeping in this world. And, yeah, there’s nothing wrong with being a tree-huggin, rock-lickin, dirt-worshippin’ eco-weenie, is there? (And don’t worry…I’ve been called worse than that!)
Peace, Love & Eternal Grooviness

@C24B9 sure no problemo

Cool experiment!
