Music playing Narrator Over 50 percent of the greenhouse gas emissions you produce in your home are generated by heating, air conditioning and hot water. In other words keeping your home warm in winter, cool in summer with nice hot water on tap is emitting 2.5 to 5 tonnes of greenhouse gas emissions each year. It also contributes a hefty amount to your electricity bill, between 50 to 60 percent. CSIRO has invented a new solar air conditioning system for Australian homes. This technology solution will reduce Australia's emissions, reduce your energy.
Bills and reduce our demand for electricity and gas. If every home in Australia installed our solar cooling technology it would be the equivalent of saving 15 mega tonnes of CO2 or taking 3.5 million cars off the road. CSIRO's solar air conditioning is an innovative three in one technology that provides hot water, cooling and heating. It uses only a fraction of the electricity of current systems and halves greenhouse gas emissions. The process begins with a typical solar hot water system. Water is heated by solar panels and stored in the hot water tank.
This solar hot water can then be used throughout the home, reducing the need for gas or electricity. A portion of the hot water is diverted into CSIRO's new solar air conditioning unit, which is divided into two compartments. The hot water enters a heat exchanger in the first compartment of the unit. Similar to a car radiator the heat exchanger uses the hot water to heat outside air that has been drawn into the first compartment through the vent. At the same time outside air is also being drawn into the second compartment into a desiccant wheel.
The desiccant wheel is the most critical part of the system. It is used to dry out the air before it goes into the house. Slowly turning the desiccant material in the wheel continuously absorbs moisture in the second compartment and then the absorbent material dries out in the first compartment. The desiccant material is dried out using the hot dry air generated by the heat exchanger. This air is then exhausted outside the home. The dry air from the desiccant wheel flows through an indirect evaporative cooler which creates a stream of cool dry air.
Turning Salt water into Drinking water using Solar power
According to the Securing Water for Food agency, between 2000 and 2050 water demand is expected to increase 55 percent globally, meaning the number of people affected by water scarcity will continue to grow. By 2025, twothirds of the world's population could be living in severe water stress conditions. Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water and much of that area is not served by an electric grid that could run conventional reverseosmosis desalination plants.
To find solution for this drinking water issue in developing countries, USAID the U.S. Agency for International Development had run a global competion for Desal prize. The idea for the competition was to create a system that could remove salt from water and meet three criteria it had to be costeffective, environmentally sustainable, and energy efficient. The winners of the $140,000 first prize were a group from MIT and Jain Irrigation Systems. The group came up with a method that uses solar panels to charge a bank of batteries. The batteries then power a system that removes salt from the water through electrodialysis,.
That means that dissolved salt particles, which have a slight electric charge, are drawn out of the water when a small electrical current is applied. Using the sun instead of fossil fuels to power a desalination plant isn't a totally new idea. Larger solar desalination plants are being seriously investigated in areas where water is becoming a scarce resource, including Chile and California.But the current technology is expensive. The MIT team's this new desalination technology electrodialysis is comparatively less expensive. Both electrodialysis and reverse osmosis require the use of membranes, but the membranes in.
Mass Price Drop in Solar Power No Longer Alternative
Big dropped in solar power prices and hopefully it will make alternative energy no longer alternative there's an article in the economist which talks about the price of photobook uh. the cost of photovoltaic bubble take cells per what but they generate right now in nineteen seventy seven it would cost seven little over seventy six dollars per walked to produce it photo vote apical take cells in nineteen ninetyseven it'd prop to about five dollars per lot and the forecast for the end of this year is only seventy four cents.
Or walked wind farms provide about two percent of the world's electricity and that their capacity is doubling every three years and we really have the opportunity to see huge growth in solar power and that the fascinating thing here is there's two ways to get more efficiency oneway is reduce the cost for the cells such that the collection of one wat goes down but then there's also allowed the cells to harness a higher percentage of the sun's energy which is where we've talked about being stuck with solar power for a while which is.
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. 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.

Solarpowered color MconneX MichEpedia
Solar energy is the only energy source that we can rely on to survive in the future. We would like to maximize the utilization of solar energy so what we have achieved here is colored solar cells you know the red stripes the blue background they are actually working solar cells. You want this material semiconductor material to absorb all the light and that's why the traditional solar panel they look black. They probably can only be installed on the rooftop because nobody's going to put these black panels on the side of the building or windows.
The rooftop area is very limited, however they are huge amount of surface area on the side of the building not only the exterior but also be interior of a building. There are ambient light that we can harvest. You want a structure to be able to absorb this light but also as a decorative item. sounds of lab What differentiates our work from work in other labs around the world most of us Connor solar cells that produce color is because the material itself that is used in building the solar cell.
They are colored but the color will be depending on your viewing angle. So depending on whether you look at from the front or the sideway the color changes yeah for this type other decorative solar panel we wanted the color to be independent of your viewing angle so here we actually borrowed a new concept and that it has to do with very thin light absorbing semiconductor on top of a metal and that produce a special optical effect that allows us to make the solar panels that whose color doesn't change.
In our solar cell we actually go one step further we have two different versions one is semitransparent and it can be made in different colors as well and the other one is purely a reflective so you can make it into a picture you know for example we made a nice U of M logo. There is a tradeoff between the multifunctionality the solar cell have versus, you know, the highest efficiency one can achieve. The black solar cells absorb the whole spectrum. A colored solar cell for example it absorbs onethird.
Of the light right I'm passing the other light that I means that the solar cell efficiency maximum will be onethird of a black solar panel can produce but on the other hand by making this multifunctional I hope that it can expand the scope of applications rather than just the rooftop in a modern home we want a lot of things to be a beautiful by why not make it was on multifunctional, not only a decorative item but can also produce electric power. V.O, In a quantum computer we don't have bits of information we have something called a.
