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.

Advantages Of Solar Energy Renewable Power
Advantages Of Solar Energy Renewable Power thespottydoggreviewsolarpoweradvantages Advantages Of Solar Energy. The sun's energy or the solar energy is the most abundant form of energy available on earth. The sun is capable of giving us more than heat and light. The sun has been one of the biggest factors dictating every living being's stay on the earth. If we go the right path, we can harness more from the solar energy, like generating power for daily use. What are the advantages of solar power The solar energy solution is gaining popularity amongst the alternate energy solutions.
Green energy solution When you look at the solar energy solution, you will realize that it uses absolutely no fuel other than the sun's light. Moreover, it does not release into the atmosphere anything harmful. Cheapest renewable power solution First, the energy comes free. Then, the installation cost is a onetime cost. Finally, the investment is recovered within a few years of installation, making the power generated by solar energy absolutely free. Convenience of storage You cannot store conventional power but you can store solar power for future use. The sun's energy comes to rescue even in the times of darkness! Storing.
It also ensures a 24x7 supply of power, thus saving you from any power outage. Low on maintenance The solar energy systems are easy to maintain. They do not involve high costs or too much effort, thus letting you reap the benefits of the solution comfortably. How can solar power be used Solar power can be used in our everyday lives by adopting the following solar power systems Solar cooking system Solar cooking is about cooking without lighting a fire or using electricity! Before you wonder, let me tell you that solar cooking is not about bland.
Food. You can cook in more ways than one boil, roast, or bake, cook the way you want! The only demand that solar cooking makes of you is being patient it is a matter of more than a few minutes. However, it is not asking for too much given that you will get tasteful and healthy food without worrying about paying your gas or electricity bill. Solar lighting system You can now light up the entire house, use every electrical appliance without thinking about cutting down bills. The solar lighting system lights up.
How Solar Energy Is Converted To Electricity Through Solar Panels
Sunlight is made up of tiny packets of energy, called photons. Every minute, enough of this energy reaches the earth to meet the world's energy demand for a whole year. Photovoltaic panels consists of many solar cells, these are materials made like silicon, one of the most common elements on earth. The individual cell is designed with a positive and a negative layer to create an electric field, just like in the battery. As photons are absorb in the cell, their energy causes electrons to come free. The electrons move towards the bottom of the cell, and exit through the connecting wire. This flow of.
Installing Solar Panels
Photo voltaic cells are an important focus of our retrofit. The photo voltaic or PV Cells are destined for the garage roof. There is enough space there to accommodate the 1.2 kW array. Current government rebates apply to the installation of the array but rebates are subject to change so you will need to check if you qualify. The panels are mounted on aluminium frames. This is vital to ensure that they are set to the correct angle. In this location it's around 7 degrees. When it is finished we are hoping to generate about 7kwh per day which goes back into the.
Grid. It may even give us some return. The panels are interconnected and the electricity fed through to an inverter. The PV Cells have a life expectancy of more than 25 years and they are virtually maintenance free so you can be assured of getting a good return on your investment. Installing a 1.2 kW array of photovoltaic cells and connecting into the grid is a relatively simple exercise. The finished array looks very neat and in these conditions will be paying its way in no time. Ok, there it is, the photovoltaic's are installed on the roof. They are wired into here, this.
Teaching Solar Energy To Kids Greenwith Primary School!
Ok kids, time for some maths! 1 1 SOLAR! Basically we're running out of oil, so everybody knows what oil is right Well oil is used to convert into petrol and we put petrol in the cars so we drive around and do all sorts of different things we want to do. The problem is that the world is running out of oil and oil is getting very, very expensive. Petrol prices are going up and it's hard to maintain those costs... One of the renewable energies they use is solar and the reason why solar is so effective is you get the energy from the sun.
Question How would you, like drive the car Well what happens is the solar energy that's generated is stored in batteries. So you know at the moment in the front of your car, you know how you've got an engine Well you don't have an engine in solar vehicles, you actually have battery packs. They can actually put sensors in clothing now so that when you do the air guitar it plays the music to match what action you're making! How cool would that be! And they can link it up with solar that actually powers the sensors, it's pretty cool stuff!.
