Solar Energy Vs Electricity

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.

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.

GivePower Foundation Solar Panels For Schools Without Electricity

A big challenge that the community has is that the kids get taught during the day and in the evening the parents don't get an education because they work during the day they can't learn because there is no light in the school. Particularly for the adults they don't get a time during the day to be able to learn and be able to learn how to read and write. A lot of the seniors want to get educated. A lot of elders within the organization want to get educated. And it's also a nice facility in the evenings for them.

To gather and celebrate. And that's why I think bringing electricity to some of these parts of the world that never had it before is so exciting and meaningful. If you can bring electricity to rural areas, people who are once isolated are less so. And I think that if we can do this right and do this well, I think we can do it over and over and over again and really have a big impact on a lot of people. A school like this just will never get electricity unless you have local generation. It needs to change. We need to create electricity.

At the place where it is needed. We can skip the legacy infrastructure and build out the new infrastructure the smarter and better way. So our mission now is to bring light to this community. In the process we are sort of teaching them the skill, they get to see how we are installing, they are participating. There are some dual benefits there. It's simple to use. We have battery backup for the system and it will create a lot of electricity for them that they can use whenever they need to. The average consumer by them taking advantage.

Of solar through SolarCity they are actually helping this community as well. I think the dream is to create a culture within a company that is all about growing and giving. At SolarCity we grow our business by over one hundred percent annually in an effort to really bring alternative forms of energy to the rest of the country. If we can find a way internally to create a culture that is about growing and giving, we're like, yes, we are growing the business. Yes, we're bringing this technology to different parts of the United States. But then how do.

NREL SolarCity Maximizing Solar Power on Electrical Grids

The growth of distributed energy resources is becoming real and tangible. Solar technologies, particularly those distributed, rooftop, PV solar technologies, add a lot of variability to the energy supply coming onto the grid. Reliability has been one of the highest responsibilities or roles of utilities. They have to deliver reliable energy to their customers. Folks that have PV on their rooftops want to make sure at the end of their day that they still have a resilient, energyefficient system. The Energy Systems Integration Facility is the only place in the country that has utilityscale capabilities.

In terms of testing and validation. Companies that are out there providing power to consumers don't want to experiment with that. They don't want to experiment with their own systems. And so, the ESIF offers them a place just like their own to do the work that will advance clean, affordable, and reliable power. Putting actual devices that we use in the field into a live circuit at NREL and doing simulation around it is a capability we can't do anywhere else. NREL partnered with SolarCity and HECO to bring together a provider of solar.

Technologies and advanced power electronics and inverters with a utility that had real concerns about operating their grid. SolarCity came in to the Energy Systems Integration Facility. They wanted to better understand how smart inverters would play with Hawaiian Electric. And as an integrator, they wanted to make sure that what they were promoting and what technology they were trying to push forward was actually sound and valid. We have five research projects with NREL. The first one is completed, and the results are done, and it's had a tangible impact in the industry, and specifically in.

Hawaii already. The test relates to a term called transient overvoltage. That was essentially a limiting factor that Hawaiian Electric Company was concerned about as far as installing distributed energy resources on their grid. Once the results came back, it basically said that transient overvoltage was not the limiting factor that we thought it might be. From a technology perspective, it was not the limiting factor on the grid anymore in Hawaii. We have these specific results in Hawaii. We anticipate, and we're getting the interest, to take those results and apply them to utilities across the country. Utilities are reaching out, they're.

Asking about it, and there's an appetite to revisit these limits. I'm a big believer in collaboration. This sort of collaboration, collaboration with utilitiesdistributed energy resource providers like SolarCity and national labs like NRELit's critical because of the pace of change in the industry. NREL can be that convening authority, that facilitator for these collaborations to bring groups together in ways that they may not individually do on their own. I think this is absolutely the beginning of a new paradigm for relationships on tackling these really challenging topics on the grid.

We hope that bringing industry partners, the utility folks together with our staff, our Energy Systems Integration Facility capabilities, all the research teams will be able to have that much further impact towards the smart grid of the future. The grid is evolving, and it's one of the biggest assets we have as a country. To change that, to bring a new technology to engage new consumers, and doing all of this in an equitable way that reduces carbon and supports the environmentit's a whole set of large, audacious goals that are incredible to work on.

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.

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.

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.

Using solar power to purify water

This technology is the product of six years of research on solar powered clean water systems at MIT. Each system is optimally configured from low cost, commercially available components using our analytical tools and software. This ensures that customers receive the best systems for their locations, input water chemistries and daily demands. Each system uses a microcomputer so it operates effectively under varying conditions automatically. This enabled end user operation with limited attention. To demonstrate the effectiveness outside of the lab, the MIT team, with the support of the Kellogg Foundation, installed a.

Prototype system in a remote Mayan farming village in the center of Mexico's Yucatan peninsula. This unit fits into a small garden shed, however it can produce enough drinking water for a village of about 450 people. The system can purify captured rain water, pond water, or brackish well water. All these have substantial dissolved solids and biological contamination. The water produced meet international water quality standards. The system is configured from easily serviced or replaced components. It is powered by solar panels. Water purification is an energy intensive process. Solar powered.
