The Future of Solar Energy is TINY Technology!

The future is huge for tiny technology. Miniaturization is, perhaps ironically, a huge deal. I mean, without it we wouldn't have had the personal computer revolution and we wouldn't have this world we live in now, where we have smartphones and tablets and other devices just as powerful as a computer, that can fit in the palm of your hand. But even these gadgets are gargantuan compared to nanotechnology! See, a nanometer is just one billionth of a meter. And that's kind of hard to imagine, so let me put it to you this way.

Your typical sheet of paper is about one hundred thousand nanometers thick. And at this scale, individual elements are so small you can't even see them with a light microscope. Now as we learn more about how materials behave on the nanoscale, we have more potential applications to use that knowledge practically. I'm talking about how nanotech could help solar panel technology. And fortunately, at a recent meeting of the American Association for the Advancement of Science, or AAAS, they had a panel on just this very subject. Now if you know anything about solar panels you know they have some drawbacks. For example,.

Efficiency they max out at around twenty percent in the field under ideal conditions. They're also rigid, so you can't just put them anywhere you like. And they tend to be expensive because manufacturing them is complicated. But scientists hope that nanotechnology can help address all three of these challenges. Now with efficiency they're looking to nature specifically, moth eyes. You see, moths have these little tiny structures in their eyes that help reflect light back into the eye and it does two things it lets them see better in the dark, and it cuts down.

On reflection so predators can't spot them as easily. With solar panels it could actually make them more efficient by reflecting more of the sun's light into the panel so you lose less in reflection. And when we're talking about flexibility, well nanomaterials are really, really small, and there is the potential to create solar panels that are just a few sheets of molecules thick. They could be as flexible as a sheet of paper, and with that kind of flexibility you could put those pretty much anywhere you wanted to.

And as for price, well, that's the big one. And in the short term I don't think it's going to turn around. But scientists are cautiously optimistic that nanotechnology will let us use new processes, like printing solar panels directly onto a substrate using just a specialized printer. That would actually be less complicated and expensive than traditional manufacturing methods. Now at that meeting of the AAAS, a Dr. Wolfgang Porod gave a talk about Nanoantenna Thermocouples for Energy Harvesting. Which I admit sounds like technobabble straight out of a Star Trek episode.

But it's actually fairly simple once you break it down. A nanoantenna is just an antenna on the nanoscale. These resonate with longwave infrared radiation. And a thermocouple Well that's a component of circuitry that generates a voltage when one part of the thermocouple is a different temperature than other part. So you pair these two together and the antenna generates heat and the thermocouple generates voltage. It could actually help increase the efficiency of solar panels. Now like I said, nanotechnology is a young science and it has lots of different applications.

Across many disciplines. And I'm really excited how such a small technology could have such a huge impact. That leads me to this week's question.

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.

solar panels installation on flat roof

Hello everyone, my name is Steve and welcome to aquaheat.uk. Today we are showing you an installation of solar panels that we've done. This is a solar panel system that provides hot water for the property. On this particular installation, we fitted two landscape solar panels on to a flat roof and they're staggered one behind the other. We've got one here and then we have another one here. They're both connected by this pipework here, it goes down, through the roof into where the solar cylinder is we can talk about.

That afterwards. So normally on these panels on a flat roof, they do sit side by side. On this particular installation to comply with local planning, they've requested that they've been fitted one behind the other, which we can do. With reverse style solar panels you can fit them on a pitched roof they'll either be on the roof or you can fit them mounted. This particular one is landscape, you can have portrait, which is like a portrait picture basically. This particular one is a Solar Worcester Bosch FKT1W. This is a.

More high efficiency solar panel, than the standard panel they do and it soaks up more UV's from the sun because of better performance. You will even find on days like today, where it is a bit cloudy and overcast that there is a lot of UV's around and you can still heat up hot water even on days like today. That's about it really it's quite a simple installation. We fit the frames, we assemble everything. We fit the solar panels in, run the pipework lagging in, it's wired into a sensor, which we've done. The next stage is.

How to Install Solar Panels Wiring for Solar Panels

Alright! We've got the panels mounted and now we're ready to connect the wiring that brings the power down to our charge controller which is located on the ground. We're going to be using this BX style wire which is just twelve gage wire with a wrapping of sturdy aluminum on the outside to protect it from the elements. Typically used in household wiring, pretty common at your home improvement center, twelve gage is adequate for a small system like this. Black wire for our positive connection, the white wire will be negative.

It's also called the neutral in an AC system. But for this we can use the white wire as negative, and then the green will go to our frame as a ground. So, we'll just strip a little bit of wire off here. We've got our DC wires already marked coming from the panels. Red, positive and white is negative. So we'll follow that here, again, and strip these wires down. Special wiring comes out of these panels. It's USE rated versus THHN for instance. And this USE wire is UV stabilized so it can actually be out in the sunlight for many years without.

Degrading. We're using the shielded wire here could be in different styles of conduit or even a UV rated wire for a small installation like this. And your bigger grid type connections, all this can be in conduit and the wire choices would be a little more limited because of the high voltages concerned. But here, twelve to forty volts, we're not really as concerned with that as we might be. Still, it's nice to have everything solid. We're going to use our linesmen pliers here to get a nice solid twist on our positive wires and a little wire nut on top of that, snug.

It down. We've got our negative wire here, and you notice I didn't strip these both at the same time. Even through it's only 40 volts, you can still get a pretty decent shock off of these panels. So, it pays to keep the wires separate. In fact, at the other end here, we're not quite ready to make this connection, we should connect down at the bottom first before making this wire completely hot, just for safety. So now, let's leave this for a moment and go down and wire up our charge controller here in the laundry room.
