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. When I say the word nanotechnology what do you imagine What does that word mean to you Let us know in the comments below. Then, do me a nanosized favor and share this tutorial with your friends.

What Countries Are The Most Energy Efficient
As emerging economies continue to expand, their energy needs are set to grow dramatically in the coming years. The International Energy Agency has even predicted that global energy use will increase by 30 percent over the next two and a half decades. With crude oil the source of so much volatility around the world, there is no question that the the future of energy will be based on countries dedicated to alternative, renewable sources. So, which countries are the most energy efficient Well, the American Council for an EnergyEfficient Economy has ranked the world's 16 largest.
Economies, which account for nearly three quarters of global electricity consumption. This is based on 31 metrics, spanning energy use in buildings, industry, and transportation. It includes things like the country's national energy savings goals, vehicle fuel economy standards, and energy consumed per foot of floor space. The United States ranks among the least efficient, at number thirteen. But across the board, Germany saw the greatest energy efficiency, scoring well in all metrics, but especially industry. According to the report, German industry and manufacturing is the second most fuel efficient in the world, with plans to far surpass the current leader,.
Australia, by 2020. Part of the reason Germany is doing so well is a national policy, dedicated to lowering energy use, known as Energiewende, or Energy Transition. The goal of this program is to stop using coal and other nonrenewable energy sources like oil. Clearly, it has been working so far. In 2014, Germany accounted for half of the new wind farms in the EU, and has been leading the world in energy efficiency. In an extremely close second place overall, Italy actually surpasses Germany in transportation. Although they tie with the UK for vehicle fuel efficiency, at nearly 40 miles per gallon.
On average, Italians also travel the least per capita. This low impact, high efficiency makes Italy a world leader in transit energy. Additionally, Italy tends to prioritize its rail system over its roads, leading to more people taking the train, and thereby saving considerable energy. Still, Italy continues to primarily use fossil fuels, and actually scores the worst in terms of commercial building energy efficiency. When it comes to buildings, China takes the lead. Their polluting past and wide range of energy inefficiency may hold them back. But China's residential buildings use less.
Energy per square foot than any other country in the report. This is partially due to strict building codes, and the fact that energy intensity is one of the country's top priorities. And despite being known for wastefulness, between 1980 and 2010, energy consumption increased five times, while the economy grew 18 times. Between Germany, Italy, and China, emerging countries can look at their journeys towards energy efficiency, and fine tune their own programs for maximum output. Still, every country surveyed has a long way to go, and plenty of areas to improve. Hopefully, 2016.
SolarCity Unveils Worlds Most Efficient Rooftop Solar Panel with more than 22 Module Efficiency.
The Sun provides endless energy, but the average solar cell panel can convert only 14 to 20 of the energy it collects into usable electricity. Now, American energy company SolarCity has built the world's most efficient rooftop solar panel, with a module efficiency exceeding 22 percent. The new SolarCity panel generates more power per square foot and harvests more energy over a year than any other rooftop panel in production, and will be the highest volume solar panel manufactured in the Western Hemisphere. SolarCity will begin producing the first modules in small quantities this month at its 100.
MW pilot facility, but the majority of the new solar panels will ultimately be produced at SolarCity's 1 GW facility in Buffalo, New York. SolarCity expects to be producing between 9,000 10,000 solar panels each day with similar efficiency when the Buffalo facility reaches full capacity. SolarCity's panel was measured with 22.04 percent modulelevel efficiency by Renewable Energy Test Center, a thirdparty certification testing provider for photovoltaic and renewable energy products. SolarCity's new panel is created via a proprietary process that significantly reduces the manufacturing cost relative to other highefficiency technologies, and it.
Los Alamos Discovers Super Efficient Solar Using Perovskite Crystals
Aditya Mohite Our group focuses on converting solar energy into electricity. And we're working on a class of solar cells which are referred to as third generation solar cells. The goal of our project was, how do we take these materials and control their crystalline properties, crystalline size, and get them to a point which are comparable to what is used in daytoday semiconductor industry like gallium arsenide or silicon. We're not there yet, silicon is the holy grail, but one of the biggest advantages of this material, at least from what we've begun to discover, is that you can make very high.
Quality crystals off this material which are large area, they are single crystalline, and they have properties which are at par with silicon or gallium arsenide. There's a lot of work that needs to be done in the engineering aspect of things, in terms of the stability you're trying to get, the right electrical contacts for them to perform at par with silicon, but I would say that this is something which will be achieved in the coming years. Wanyi Nie So, we developed a new technique, it's called the hot casting process, where we keep.
Our substrate hot and solution hot and do the spincoating at elevated temperature and at the same time the film color will be converted from light yellow to dark brown which means we're forming a highquality crystalline grain, and if we look at it under the microscope we are able to achieve up to millimeter scale large crystal grains. Normally for the crystals to grow usually require high temperature or sophisticated processing, but this method is kind of low temperature and easy solution processing. Mohite There has always beena lot of defects and disorder and multiple interfaces.
That has plagued efficiencies, and so by growing these crystals of highquality you have sort of circumvented that problem and solved an important bottleneck which has existed in this field of nanomaterial, solutionbased solar cells, third generation solar cells. Solar energy is trying to tap into the unlimited amount of solar energy that falls on Earth and that's basically free, and if you can harvest that at a very, very low cost, much cheaper that what is used, by burning coal for example, and fossil fuels, then that gives us a route to really be completely energy.
Renewable Energy Efficiency
You can never take no for an answer. When people say things can't be done you really have to be very skeptical and sometimes it requires a lot of perseverance to get through the no's. Energy is the lifeblood of America and indeed any nation. The more we as a nation and in fact avoid the use of our energy and actually produce it home, improves our energy security worldwide and actually increases our economic competitiveness and our environmental quality. When we started this process nobody thought it was possible to build a super energy efficient building that.
Could achieve netzero energy with the amount of money we had and what it required really was to change the way we look at the design process, to bring people in the design process up front and early. The success in this building is really driven by its ability to achieve that 50 percent energy efficiency standard and we can actually add that photovoltaics to make it zero energy. This building is about 20 percent recycled materials including concrete from the now disassembled Stapleton airport. One of the things you'll notice when you walk into the building is that every workspace is.
Day lit. In fact, a 100 percent of our space is day lit. Nobody is more than 30 feet from a window. Other highlights of the building, there's no heating or air conditioning in the traditional sense. It uses evaporative cooling to, in fact, chill water. Out heat is provided by what's called the renewable fuels heating facility, where we actually burn biomass to generate hot water. The big feature of the building is using water to, in effect heat and cool the building. Which is much, much more energy efficient. The uprights of the building.
Are actually natural gas pipes that have, in effect, been reconditioned to provide the structural framework for the building. The advantage that we have by incorporating all these materials and techniques is that, again, we produce a highly energyefficient building, it's gonna save us money over the long run as we operate it, since we're only paying about half as much for utilities costs but the other benefits that we've created by doing this process is that we've made a space it is much more fun to work in. Lots of studys show that if people have access to day light.

New solar system for improved energyefficiency
Finding creative solutions to energy issues and energy efficient buildings has become a major priority for Europe in recent years. Today simple, nonpolluting technologies are deployed quickly. This industrial building in Malta hosts the prototype of an EUfunded optical system developed in the framework of the European project DiGeSPo. Its Concentratedsolar technology will be used to produce heat and electricity. The system uses mirrors with a tracking system to focus sunlight onto a receiver which contains a heat transfer fluid. The EU is aiming for a 20 cut in Europe's annual.
Energy consumption by 2020. Digespo is contributing to that objective by developing a new solar technology. The prospects of strong growth for Concentrated Solar Power over the next few decades seem good. This will help develop a competitive industry and foster EU partnerships. As we are all aware, there are about 160 million buildings within Europe. We see this as a unique challenge to be one of those buildings where we can generate energy efficiencies and energy improvements. Houses and buildings consume up to 40 of total EU energy use. Digespo and its mini solar power systems will.
In the long run allow homes and workplaces alike to generate their own electricity and meet their heating and cooling requirements. The Digespo project is a fantastic opportunity to exploit the huge potential and solar resources especially on an island like ours or in the Mediterranean region but also a very good opportunity for us to transfer knowledge which is mostly acquired from mainland Europe and solar research to the Mediterranean region in general. This is just the beginning As we become bigger consumers of energy, the European consortium of the DiGeSPo project wants.
Making Solar Energy More Affordable, Efficient
Siliconbased solar cells are the rule, but a University of NebraskaLincoln scientist hopes to change the industry standard using new materials and manufacturing methods. Jinsong Huang's research has been featured in the magazine, Science, and is supported by the National Science Foundation and the U.S. Department of Energy. Huang makes solar cells using perovskite, a material with a crystal structure that has proven almost as efficient as silicon, but much less expensive. Thin layers of material are applied using a technique called spin coating. The next step is to demonstrate the device is stable.
Saving Energy with Solar Power Designing Windmill Blades for Energy Efficiency
The other thing is, when you want to build one, it's very difficult to get the right shape of the blades because these blades have to be very carefully designed that they get most out of it. You would not believe it, but when you see it here, these blades are spinning 3 times faster than the wind. Why Because of the design of the blades, they can spin faster than the wind is blowing. The windmill by itself will start producing electricity with about 6 to 7 miles per hour and then it goes up and gets its peak, its.
Energy 101 Concentrating Solar Power
Bjbj Take the natural heat from the sun, reflect it against a mirror, focus all of that heat on one area, send it through a power system, and you've got a renewable way of making electricity. It's called concentrating solar power, or CSP. Now, there are many types of CSP technologies. Towers, dishes, linear mirrors, and troughs. Have a look at this parabolic trough system. Parabolic troughs are large mirrors shaped like a giant U. These troughs are connected together in long lines and will track the sun throughout the day. When the sun's heat.
Is reflected off the mirror, the curved shape sends most of that reflected heat onto a receiver. The receiver tube is filled a fluid. It could be oil, molten salt something that holds the heat well. Basically, this super hot liquid heats water in this thing called a heat exchanger and the water turns to steam. The steam is sent off to a turbine, and from there, it's business as usual inside a power plant. A steam turbine spins a generator and the generator makes electricity. Once the fluid transfers it heat, it's recycled and used over and over.
And the steam is also cooled, condensed and recycled again and again. One big advantage of these trough systems is that the heated fluid can be stored and used later to keep making electricity when the sun isn't shining. Sunny skies and hot temperatures make the southwest U.S. an ideal place for these kinds of power plants. Many concentrated solar power plants could be built within the next several years. And a single plant can generate 250 megawatts or more, which is enough to power about 90,000 homes. That's a lot of electricity.
