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.

NCSEA Renewable Energy Energy Efficiency Industries Census.flv
Gtgt Betsy Sykes WHAT WERE THE PARAMETERS OF THE CENSUS THIS YEAR AND HOW DID YOU TARGET CENSUS PARTICIPANTS gtgt Paul Quinlan Well, This is the fourth year we have conducted this annual study. And what we are looking for is we did a renewable energy efficiency study. So it's a little more focused than some green jobs studies, national green jobs studies that exist out there. And what we look for is we look for companies that have 50 percent of their revenue that comes from renewable energy or energy efficiency activities or 50 percent of their.
Staff time goes to renewable energy or energy efficiency work or that there's 25,000 in economic gain or savings come from renewable energy or energy efficiency within the company. We built the list over the last four years and it has over 1500 firms on it now of companies that we believe to be in this workplace. And what we do each summer is we survey them first through a online platform and have them sign in and take a survey and then we also do phone banking and on the second half of the project. And that's how we target companies. It's a.

Korea opens solar innovation center in Chungcheongnamdo province
It was a very fitting sunny day for the opening of an innovation center dedicated to the solar energy industry.part of the Park Geunhye administrations creative economy drive. The president was there for the ceremony and promised her full support for small and midsized firms there. Shin Semin reports. Koreas eleventh innovation center opened Friday with great fanfare in Cheonan in the western province of Chungcheongnamdo. The opening of the center which is dedicated to the solar energy sector coincides with Koreas drive to go green by cutting carbon emissions seeking renewable energy sources and lessening its dependence on fossil.
Fuels. President Park Geunhye who spoke at the opening ceremony promised to foster the solar energy industry by spurring innovation in the sector and helping smallandmidsized companies extend their reach into the global market. The center will provide support to small and midsize companies to help develop this new market which involves products powered by solar energy and related startups in the solar industry. President Park also referred to a global solarpowered product market that grows more than 15percent annually. She added that the global shift towards going green and using clean energy instead of fossil fuels poses great challenges but said.
It offers a myriad of opportunities for the Korean economy. To support the new center Hanwha Group has unveiled its plan to build a selfsustainable solarpowered island by wiping out diesel power generators and replacing them with solar panels. Hanwha Q CELLS one of the worlds leading photovoltaic companies is also investing some 27million U.S. dollars to build a plant in the western coastal city of Seosan. that will help smaller firms test their products. The government plans to open six more creative economy centers by the end of June bringing the total to 17 nationwide.
Energy Label for Windows
Today in Europe over 85 of windows are wasting too much energy and market forecasts show that over 1billion of new windows will be sold by 2030 This is a huge opportunity to save energy reduce CO2 emissions and make Europe's buildings healthier. But how to grasp these benefits How to help consumers make the right choice Laura and Alex think it's time to invest and decide to have the windows of their house replaced. They hope to upgrade their home, make savings on energy bills, but foremost expect to improve their comfort.
Soon Laura and Alex are lost they are not experts and are afraid of making a wrong choice. It's their house. Of course they want to understand what they are buying. The solution could come from Europe an EU energy label for Windows. But how should this European energy label look like to help Laura and Alex A window energy label must be both accurate and simple. It must provide a clear ranking of windows performance throughout the year. It would take account of the location Alex and Laura's house. On top of that, it could provide them with information on.
Czech renewable subsidies make way for fossil fuel subsidies
I think there's still time for the Czech Republic to take another look at its strategy and adopt some support mechanisms. If this doesn't happen and there is no planned support as proposed in the Senate bill, the law will be in place until 2020 and it is almost certain that the Czech Republic will not meet its required share of renewables in the energy mix. We had a conversation about the law with the chamber of renewable energy an umbrella for all professional renewables associations windpower plants, photovoltaics,.
Geothermal resources and alike. We suggested a number of measures. I'll mention two the first was a continuation of the photovoltaic tax since the Czech Republic has a certain disproportion in the field. Support for photovoltaics in 2009 and 2010 was too big. The Ministry of industry didn't lend its support to this suggestion. Fortunately we were successful with the government in integrating a tax in the current law. So the support will be fair There will be some proportionality. The other thing we suggested was the withdrawal of support for communal waste incineration.
