Solar Energy What Is It

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.

Why Should We Launch Solar Panels Into Space

This episode of DNews is brought to you by Full Sail University. This week the Japanese Aerospace Exploration Agency announced it wants to get solar power from space. I'm having flashbacks to disasters from SimCity2000. Hello! I'm Trace. Thank you for watching DNews. Back in the 1960s, American aerospace engineer Peter Glaser proposed launching solar panels into space, and beaming the power they collect back to the surface for our use. Since the late 60s the idea has been in a holding pattern mainly because of the expense and worries about maintenance and equipment, but thanks.

To recent developments in solar panel tech the Japanese space firm JAXA says they can finally try it. The plan is ambitious at minimum and cost hasn't yet been calculated, BUT JAXA is determined, and they're not the only ones. The U.S. Naval Research Laboratory is also interested in spacebased solar. The reason everyone's looking up, is because that's where the sun sits! If we can put a satellite in orbit to collect the sun's rays BEFORE the atmosphere filters them out, and without the worry of a cloudy day, that would be rad. The JAXA Space Based Power System.

Or SBPS will orbit 22,400 miles up, and if done to their specs, would completely replace a nuclear power plant by producing 1 gigawatt of electricity enough to power halfamillion homes. Their plan uses a 10,000 metric ton system, which is. well pretty ridiculous. The largest rocket ever launched was the Saturn V it took our boys to the moon and could only lift about 130 metric tons. Once the power is gathered, a converter in space will convert the electricity into a microwave beam not like in your house, literally waves of energy that are.

On the micro scale. Microwaves can be converted from energy at 80 percent efficiency, which means there would be some loss, but it would be pretty damn efficient about 48 of the power collected would reach consumers. Which doesn't sound great, but it really is. To make sure the array is getting sunlight 24hours a day, JAXA plans to put mirrors on either side of the planet to reflect sunlight at the collector all the time. The Japanese are announcing their plan so far in advance in the hope other countries.

Will gather and help realize the dream of solar from space. Once created, it could provide clean, unlimited energy anywhere on the planet, regardless of remote location. Here's the kicker. It would cost about a trillion dollars. Which sounds like a lot, but it's like 125 bucks per person on the planet in 2030. And that's WAY more than you're paying doe your power bill. Not to mention oil wars and all the pollution, ecological damage, mining and drilling that goes with fossil fuels. We've got commenting areaaassss, check them out and type your feelings on spacebased.

Solar so we can all talk about it! None of this would be possible without computers to run the system, and we need people to write the computer programs. Full Sail University in Florida offers courses to help train tech professionals by blending code and realworld experience. Students of Full Sail have handson access to technology on their first day, get a discounted laptop and all the software they'll need to earn degrees in software, mobile and web development.

No, Solar Panels Dont Suck Up All The Suns Sun Juice

Gtgt THERE ARE A LOT OF NEW FORMS OF ENERGY THAT ARE ACTUALLY GROWING ALL ACROSS THE COUNTRY. WIND, SOLAR, AND TO BE FAIR TO WOODLAND IN NORTH CAROLINA, THEY HAVE DONE THIS SEVERAL TIMES, THEY HAVE THREE SOLAR FARMS THAT THEY APPROVED IN THE WOODLAND TOWN COUNCIL SO FAR. A FOURTH ONE HAD COME UP, THAT IS WHERE WE RAN INTO SOME ISSUES. SOME CONSTITUENTS CAME IN AND ARGUED, AND TO BE FAIR TO THE LEGISLATORS, THEY DID NOT MAKE THESE ARGUMENTS, CONSTITUENTS DID. LET ME QUOTE THE ROANOKECOWAN NEWS HERALD.

Gtgt I ALMOST MADE IT AN ENTIRE HOUR WITHOUT THE COUGH, HOLD ON. gtgt ALMOST. gtgtHERE IS WHAT I AM SURE OF, THERE IS NO BROWN VEGETATION NEAR THE SOLAR PANEL, BECAUSE THE SOLAR PANEL IS SUCKING UP THE OTHER PHOTOSYNTHESIS FROM THE AREA. OH NO, YOU SUNLIGHT, YOU ARE NOT GOING OVER THERE. THE SOLAR PANEL IS GRABBING YOU. THE SOLAR PANELS FOR THE SUNLIGHT THAT HITS THE SOLAR PANEL. JANE MANN CONTINUED gtgt SCIENTISTS COULD TELL YOU, AND YOU ARE A FORMER SCIENCE TEACHER. I COULD TELL YOU. BUT APPARENTLY YOU WOULDN'T LISTEN,.

SO MAYBE WE SHOULDN'T WASTE OUR BREATH. BOBBY MANN, ANOTHER FAMILY MEMBER, CAME WITH HER, AND HE HAD ANOTHER THEORY gtgtTHOSE ARE TWO DIFFERENT THEORIES, TO BE FAIR, PUT BIZARRELY IN THE SAME SENTENCE. I DON'T KNOW WHY BUSINESSES WOULD NOT COME TO WOODLAND IF THERE WERE SOLAR PANELS, I DON'T UNDERSTAND THAT ALL. THEY ALSO CLAIMED, OTHER CONSTITUENTS DID, THAT THE SOLAR PANELS WERE DRIVING THE YOUNG CITIZENS OF WOODLAND AWAY. I DID NOT KNOW MILLENNIALS WERE ANTISOLAR PANELS. I HAD NO IDEA. I DID NOT KNOW THAT THE YOUNG OF WOODLAND.

WERE PERHAPS VAMPIRES AND DID NOT LIKE SOLAR PANELS BRINGING IN ALL THAT SUN. BUT THE FIRST PART OF HIS THEORY I'M FAIRLY POSITIVE ABOUT. HE SAID THE SOLAR FARMS WOULD SUCK UP ALL THE ENERGY FROM THE SUN. I AM SURE THE SUN IS GOING TO BE OKAY. COMPANY REPRESENTATIVES HAD TO COME IN, THIS IS STRATA SOLAR COMPANY ARGUING FOR THE SOLAR FARM, AND THEY HAD TO BOTHER SAYING THIS gtgt THEY ONLY DRAW THE SUNLIGHT THAT FALLS ON THEM. gtgt THEY HEARD FROM CONCERNED CONSTITUENTS WHO APPEARED TO NOT.

HAVE THEIR SCIENCE EXACTLY RIGHT, AND THEY HEARD FROM COMPANY REPRESENTATIVES, TO BE FAIR, BUT ALSO THE SCIENCE ON THIS IS NOT OVERLY COMPLICATED. I AM PRETTY SURE THE SUN HAS NOT BEEN DRAINED OF ALL ITS ENERGY BECAUSE OF SOLAR PANELS. HOW DID THE VOTE COME OUT THE VOTE ON THE SOLAR PANELS THIS TIME AROUND, 31 AGAINST. SORRY, NO MORE SOLAR PANELS IN WOODLAND COUNTY, OR WOODLAND TOWN. THOSE ARGUMENTS WERE PERSUASIVE. gtgt OKAY, WELL, THANK GOD WOODLAND TOWN DID NOT PUT UP ANY MORE SOLAR PANELS, OTHERWISE NONE OF US MIGHT BE ABLE TO USE.

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.

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 to Install Solar Panels Battery Banks for Solar Energy

Now we come to our battery bank for our Solar system. This one is made up of six volt cells combined in different ways to get the voltage we need for our individual inverters. We're going to be using the big Zantrax 1,000 watt this time, so we'll need two six volt cells, in series, to come up with that twelve volts. If you take your battery and connect a positive to a negative terminal that leaves you with a positive and negative terminal and you can get your twelve volts here. If you connect four batteries in series, positive to negative,.

You come up with twentyfour volts. And if you needed a fortyeight volt system, which is not uncommon, you'd simply expand and use more batteries. But for a twelve volt system we'll just use two. And, they're really the most dangerous part of the system. If you look down inside there, you can see a liquid and that liquid is sulfuric acid and will really seriously burn you and that's why we have a base here, Baking Soda, and if you get that acid in your eyes or in your clothing you can neutralize it with this. So, very.

Important to have this for safety. We can get a look at some of that acid here with the hydrometer, this is what you measure the actual specific gravity of the acid inside. And you can see we have several of these disks floating. We have about three disks floating with one at the bottom. So we know that this two batteries, or at least this battery, is about seventyfive percent charged. So, we're going to be very careful with that acid and stick this back here in our little cup. It's also important to note that the gases that.

Federal Tax Credit for Solar Energy TurboTax Tax Tip Tutorial

Hello, I'm Jeremy from TurboTax with important news on how you can reduce your tax bill and protect the environment at the same time. Have you installed solar powered equipment in your home this year Or are you considering it If so, the federal government will reward your environmentally conscious home improvements with a tax credit equal to 30 percent of your purchase and installation costs. There is no maximum on the amount of credit you can claim. Essentially, the credit works like this. If you spend 10000 dollars to buy and install solar panels on your roof,.

Your credit will equal 3000 dollars. If at the end of the year, you owe 5000 dollars in taxes, the credit reduces your tax liability to 2000 dollars. If you haven't purchased the solar powered equipment yet, don't worry. You have until 2016 to do so. There is, however, one notable limitation to the credit. It is only available for improvements that you make to your main home which is generally your principle residence where you live for most of the year. You can also increase your tax savings by claiming similar credits for energy efficiency improvements.

Plants vs Solar Panels Which is better at capturing solar energy AtBristol Science Centre

This is an aquatic plant called pondweed, and we can see that it's making tiny bubbles of gas. This gas is oxygen and all plants produce it in a process called photosynthesis. The word photosynthesis comes from the Greek meaning light' and putting together'. Plants use the energy in sunlight to make sugars, out of the simple ingredients of carbon dioxide and water. And do you remember those bubbles of gas we saw earlier Well. deep breath they're pretty useful. To make the sugar, or glucose, the bonds which hold the molecules together.

Have to be broken apart and rearranged. The bonds are made of electrons. So the water needs to lose electrons, and the carbon dioxide has to gain electrons. And the colour of leaves gives us a clue to what is responsible for this rearrangement of electrons. Every leaf cell contains a pigment called chlorophyll'. It's the chlorophyll which makes the leaves green and helps make photosynthesis happen. Chlorophyll has the amazing ability to release electrons when exposed to sunlight. The electrons from the chlorophyll are replaced by splitting apart water into ions of hydrogen and oxygen.

The excess oxygen is then released into the air. The flow of electrons from the chlorophyll is then used with the remaining hydrogen ions to produce the energy needed to synthesise glucose from molecules of carbon dioxide. So sunlight provides the energy we need to move electrons from one molecule to another turning light energy into chemical energy ready for our plant to use. But can we do the same thing artificially How does photosynthesis compare to a solar panel Well, solar panels like those on the Energy Tree.

Use light as an energy source, and they also generate a flow of electrons. But they don't store chemical energy they convert light energy into electrical energy. They do this by using something called the photoelectric effect'. When photons come and hit a metal surface, they knock off electrons. We then capture and store these electrons. These photovoltaic cells are made of a silicon crystal. But silicon is a poor conductor of electricity. So impurities are added to help. This creates something called a 'semiconductor'. As light hits the surface, electrons are knocked loose.

The electrons then flow from areas with a high concentration, to areas with a low concentration. It's this flow of electrons which generates an electric current. We've done this on a big scale on our roof. We have 560 square metres of solar panels, which generate 47,000 kilowatt hours of electricity per year. So which is better, leaves or solar panels How efficient is each system at transforming the energy from sunlight Well, a leaf can turn only three percent of light energy hitting its surface into chemical energy through photosynthesis.

Whereas, a solar panel of the same area can turn roughly ten percent of the light energy into electrical energy that's over three times more efficient! But it's not quite as simple as that. There's all sorts of other things to take into account as well. Such as the time of day, the location, types of plant, and transport and storage costs on the other side as well. Solar panels may be able to absorb more wavelengths of light than leaves, but leaves can grow and repair when damaged. The Energy Tree may be able to charge your phone,.
