Making Solar Power Lights

How Do You Make a Solar Backpack Design Squad

Hi, I'm Deysi from Design Squad, and we got lots of really cool ideas for our Build it Better challenge where we ask you to help improve the design of things you use every day. Aaralyn06 took the challenge to design school supplies that work better and sent in a design for a solar powered lighted backpack. I'm excited to make a prototype of this idea. A prototype is a simple model that lets you test out your ideas. Prototypes help you understand the strengths and weaknesses of your design and how your design can be improved before you build it.

This is a solar panel, and this is how it works. A solar panel uses solar cells. A solar cell uses sunlight to make electricity. Electricity is the flow of electrons. In a solar cell, sunlight makes electrons move. A solar cell has two layers. The first layer has lots of electrons that are easy to move. The second layer has fewer electrons so it can easily take on more electrons. When light hits an electron in the first layer, it causes the electron to jump to the second layer. The sunlight starts this flow of electrons, which is electricity.

Okay, let's get started. So I have my backpack and two different kinds of solar powered lights. See how these work The rope lights are connected to the solar panel, and it turns on when the solar panel is in darkness, like this. grunting Make sure you get a grownup's permission before you cut up a backpack. We want to keep the solar panel on the outside so that the Sun can charge it during the daytime. I have another set of lights that I'm going to use for the inside of my backpack.

So that we can catch those dark corners and light them up. Ooh, look at that! The solar panel got dark and it lit up the lights. Okay, let's try this out now. grunts Oh, I'm noticing something right away. It's actually really heavy. I think that second set of lights added a lot of weight to it. But that's the good thing about prototypes. Prototypes help you understand the strengths and weaknesses of your design, and the weakness of my design is that the lights are making it too heavy.

So let's redesign. I am actually going to remove the lights from the inside. Okay, let's remove the lights. Now we're ready. Oh, much lighter now. Now it's time to test this backpack out in the dark. Woo! This actually works! The backpack is lit up. Awesome idea, Aaralyn06. Now people will be able to see me in the dark and I'll be able to see all the things inside my backpack. Send in your photos of your designs to the Design Squad website and see what other designs kids come up with.

Burning Stuff With 2000F Solar Power!!

In a previous project I found a free tv and turned it into a giant solar scorcher. This shoots out a deadly beam of sunlight, that's hot enough to abuse food, melt metal and burn things you probably shouldn't. Today seemed like a good day to play with my Solar Scorcher. I positioned my frame and found the focal point, then added some concrete tiles as a base for my projects. Ok, I've got power, and I'll test it out with this piece of wood and when the light makes contact.

I've got instant fire. The sunlight at this spot is around 2000 degrees Fahrenheit, enough to melt this spot of concrete into a glowing orange liquid. I'm curious to see what I can do with all this heat so I've filled a glass bottle with water and I'll punch a hole in the cap. It's incredible to see that the instant I focus my lens on the bottle, it starts smoking. Just a few moments later this water is so hot it's boiling, and I'm a little nervous the bottle might blow. Yep, there it goes. The glass pieces are melting and that's cool,.

But now I want to try this on some food. I'll get some hot dogs, and when they hit the beam they really do get hot. This might be a little well done for my taste, and I'm still hungry so let's try an egg. The egg is actually working very well. It's so reflective it doesn't burn as fast, and even my wife is interested. A little salt and pepper and it's tempting to try a bite. Ok, so I wasn't actually expecting to eat this, but it looks safe enough, and.

Even my kids are anxious to try. Surprisingly, it's pretty good. Alright, let's see what else this will do. I'll try burning a penny, and, wow, it melted. How about a stack of pennies Yep, they're nothing but liquid metal now, and I'm thinking that slag in the mixture must be what's left of the copper coating. It's only taking about 4 seconds to melt these, and melting metal is really great, but now I want to see something burst. I wonder what would happen to this egg It's spewing some kind of debris and smoking like crazy. I hear.

Some little pops and it's even forming some interesting growths. huh, Look at that. But no explosion. How about if I put a pop top on this bottle of water and let the pressure build up Yeah, that's what I'm looking for. Let's do that again. The lid is back on, and pressure is building. Awesome! Alright, the sun is setting and I've readjusted my Aframe. I'm just wondering if this would ignite gasoline. It does. Hopefully it goes without saying that this is very dangerous and you shouldn't try this at home. Well, I'm convinced there's.

An insane amount of power behind these lenses. If you'd like to see where I got this one, take a look at my tutorial on how I hacked it out of an old TV. This one boiled water in less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in it's way. Well that was fun, but I'm still hungry so I'll put everything away and go get some real home cooking. That's it for now. If you liked this project, perhaps you'll like some of my others.
