Energy Electricity in Science How Is Solar Energy Used
Hi I'm Steve Jones and I'm going to tell you some of the uses of solar energy. Now solar energy is one f those strange sources of energy which is very seldom used on its own. The reason for this is that the source of the energy, the sun is not always there and therefore if you don't have an alternative source the thing that you are using won't work. So for example in home use very often people will have solar panels on the roof. This will supplement a service from the main supply so you get your energy coming in from the main supply.
So you get your energy coming in from the mains and its switched off when the solar panels are working but when the solar panels start to fade and it starts going dark then the mains takes over. It often is combined with wind power so a combination of wind power, solar energy, and mains energy is the most economical way of running things. Things like calculators are often giving a set of solar cells and this helps to prolong the life of the battery that you put in but you still have that second source of power the battery.
There are many green sites, many green places where people try and demonstrate how efficiently you can use the energy by using solar energy, wind power, water power and so forth. Well there are lots of green sites that show this. The one problem with solar energy is the initial cost is very high and very often the cost can kind of be replaced after about ten years and then you have to replace the whole of the system as well so very often it is not actually cheaper than fossil fuel energy. An interesting use nowadays is on motorway.
Interested in buying used or discounted solar panels
Tips for Buying Used or Discount Solar Panel One of the main drawbacks of solar panels is their cost. Recouping their cost can often take as long as twenty years. That means that you'll essentially have earned zero profit in twenty years you only start saving money from that point forward. Instead of buying retailpriced solar panels, a great way to get more bang for your buck is to invest in used or discount solar panels instead. Here are a few tips for finding and acquiring below retail rate solar panels.
Talk to Realtors in HighNetworth Areas Look for areas where there are many homes with solar panels. If you can find homes for sale that have solar panels on them, so much the better. But even if you can't, talk to realtors in the area anyway. Make them an offer to purchase any solar panel that's on a property they're trying to sell. Realtors often find that prospective buyers don't want solar panels on their home because of aesthetic reasons, or they just don't want the extra cost. It's a burden on selling a home, which means it can often convert into prime opportunity.
For buying a cheap panel. Look for OutofDate Models Another method for finding used solar panels is to contact manufacturers and distributors directly and ask for older models of their products. Often times when a manufacturer updates their product line, they'll try to sell off all their old products at discount prices. In fact, if you can find a distributor or manufacturer who still has solar panels from two models back, chances are you'll be able to get a steep discount on those solar panels. Join a Discount Buying Group Buying just one set of solar panels can be quite expensive. However, if you're buying.
Ten to twenty sets of solar panels, you can get a much better deal. Naturally, you're not going to buy that many solar panels on your own. However, if you join a solar panel buying group, you can often buy these panels together instead and get a nice discount off the price. Always Get the Panel Tested Before you pay for a used or discount solar panel, make sure you have a trained professional test it out. Often times the manufacturer or installer will be happy to administer the test for you for free.
Also check the solar panels for any clear damage. Check both the front and the back of the solar panels. In some panels, damage to the back is actually much more important than damage to the front, so don't make the mistake of only checking the front panels. Seriously consider buying a warranty for any used or discounted solar panels. Finding discounted or used solar panels isn't as easy as buying retail, but you can save a lot of money doing so.

Burning Stuff With 2000F Solar Power!!
In a previous project I found a free tv and turned it into a giant solar scorcher. This shoots out a deadly beam of sunlight, that's hot enough to abuse food, melt metal and burn things you probably shouldn't. Today seemed like a good day to play with my Solar Scorcher. I positioned my frame and found the focal point, then added some concrete tiles as a base for my projects. Ok, I've got power, and I'll test it out with this piece of wood and when the light makes contact.
I've got instant fire. The sunlight at this spot is around 2000 degrees Fahrenheit, enough to melt this spot of concrete into a glowing orange liquid. I'm curious to see what I can do with all this heat so I've filled a glass bottle with water and I'll punch a hole in the cap. It's incredible to see that the instant I focus my lens on the bottle, it starts smoking. Just a few moments later this water is so hot it's boiling, and I'm a little nervous the bottle might blow. Yep, there it goes. The glass pieces are melting and that's cool,.
But now I want to try this on some food. I'll get some hot dogs, and when they hit the beam they really do get hot. This might be a little well done for my taste, and I'm still hungry so let's try an egg. The egg is actually working very well. It's so reflective it doesn't burn as fast, and even my wife is interested. A little salt and pepper and it's tempting to try a bite. Ok, so I wasn't actually expecting to eat this, but it looks safe enough, and.
Even my kids are anxious to try. Surprisingly, it's pretty good. Alright, let's see what else this will do. I'll try burning a penny, and, wow, it melted. How about a stack of pennies Yep, they're nothing but liquid metal now, and I'm thinking that slag in the mixture must be what's left of the copper coating. It's only taking about 4 seconds to melt these, and melting metal is really great, but now I want to see something burst. I wonder what would happen to this egg It's spewing some kind of debris and smoking like crazy. I hear.
Some little pops and it's even forming some interesting growths. huh, Look at that. But no explosion. How about if I put a pop top on this bottle of water and let the pressure build up Yeah, that's what I'm looking for. Let's do that again. The lid is back on, and pressure is building. Awesome! Alright, the sun is setting and I've readjusted my Aframe. I'm just wondering if this would ignite gasoline. It does. Hopefully it goes without saying that this is very dangerous and you shouldn't try this at home. Well, I'm convinced there's.
An insane amount of power behind these lenses. If you'd like to see where I got this one, take a look at my tutorial on how I hacked it out of an old TV. This one boiled water in less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in it's way. Well that was fun, but I'm still hungry so I'll put everything away and go get some real home cooking. That's it for now. If you liked this project, perhaps you'll like some of my others.

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.

Stupid Virus Plagues NC Belief That Solar Panels Will Harm the Sun
So this story sounds like it came straight from an episode of South Park but, no, it really happened! Ignorant townspeople in South Carolina used their backcountry, hicktown education to prevent the rezoning of land which would have been used for a solar farm, because they suspected that the panels were causing cancer, impeding photosynthesis, and just generally sucking up too much sun. So let's look more closely at some of these concerns, shall we A retired schoolteacher from the area expressed concerns that the solar panels would prevent plants from using photosynthesis. Surely there must be some clear high school level science.
To prove her point No, not really. The woman claimed that she had noticed some vegetation around the sites of current solar panels which looked brown and dead, which was clearly an indication that the plants weren't getting enough sun due to those pesky panels stealing it all. That's a great use of the scientific method, Teach'! The retiree also expressed concern about the risk of cancer she felt the solar panels posed. She stated I WANT TO KNOW WHAT'S GOING TO HAPPEN. I WANT INFORMATION. ENOUGH IS ENOUGH. The husband of the retired schoolteacher also threw his opinion into the mix, saying that.
Solar farms would suck up all the energy from the sun and that somehow, this lack of energy would cause businesses to move out of town. A legitimate concern, you might say. Except for the fact that the sun produces enough energy in an hour to power a lightbulb for each person in the world for their entire lifetime. And that's just in an hour! The sun continuously pelts the earth with 35,000 times the amount of energy required by humanity, so rest assured hicks worldwide, those solar panels aren't going to take your sunshine away.
One of the solar panel company representatives Brent Niemann reminded the braindead townspeople that the solar panels don't draw additional sunlight, but only absorb sunlight that is reflected onto the surface of the panels. Unfortunately, this story doesn't have a happy ending, as the ignorance from the schoolteacher, her husband, and the army of other uneducated citizens was successful. The land has not been rezoned, the solar farm has been rejected, and a moratorium has been placed on allowing any future solar panels to be installed in the town for the foreseeable future.
Which Solar Panels to Use
Namaste Solar primarily installs from three manufacturers SunPower, Sharp and Kyocera. Your Sunpower panel and your Sanyo are you two high efficiency high end panels, so must power per square foot but also the most cost per watt as well. Those panels are very popular when you have very limited roof space and you want to maximize how much power you get on your roof. Sunpower also has the nice added benefit of an all black ascetic that you don't get with any other panels and that is really popular with homeowners.
Then your Sharp and Kyocera panels are your low efficiency but lower cost panels so those can really make sense when you have a lot of roof space in order to fit the solar system. So which one has the most bank for the buck Sharp or the Kyocera They are actually quite comparable, Sharp has their own racking system now, which is called SRS aestecally is nice because black frame system which sits low to the roof but sometimes you do not get the flexiblity with that system because of the low profile and.
Because it is a frame you need to have some margin of roof space around the system to work so you end up losing a little bit of real estate with that system that you can't go over attic vents and those kinds of things. Where as with a panel like Kyocera can be used with standard 3rd party mounting systems such as Unirack or ProSolar and those tend to be pretty flexible and can often clear some roof obstructions and go right to the ridge of the roof or gutter of the roof.
