Wouldn't it be weird if one day in the future you were buying a home and the listing said, batteries not included Yeah well, that could totally happen. Hey there people, Julian here for DNews. Electricity is pretty great. It powers my toaster, my fridge, my hairdryer, my clothes dryer, my air conditioner, my humidifier, my dehumidifier, and my pc I use to watch science tutorials. I think I'm gonna keep using it. The problem is, everyone in all the other houses feels the same way, usually at about the same times.
Of day, and they're driving the cost of those tasty kilowatts up in the evening. Of course during the day if you don't want to use power from the grid, you could get some solar panels and harvest sunlight, but that's not helpful when the sun's down, also known as nighttime, also known as the time I need to have electricity to turn lights on to not bang my shins on all the furniture. Enter the battery powered home. The idea is a rechargeable battery stores energy from solar panels during the day or from offpeak hours when grid energy is cheapest, and uses.
That energy during the rest of the day. The problem is if you've ever bought batteries you know they cost approximately one arm andor one leg. Elon Musk thought that was a silly hangup for what is otherwise a great idea and decided to do something about it. Elon Musk, for y'all that don't know, is basically what would happen if Tony Stark lost the goatee. His interests range from online money movement to commercial space flight to, most importantly for this topic, electric cars. His company Tesla Motors has been refining electric car batteries for years, engineering them to be lighter, longer lasting,.
And more efficient. Why don't we take all those batteries, and put them on a wall So they did that. The Tesla Power wall Is basically a bunch of lithium ion cells in a sleek case. They're compartmentalized and liquid cooled to solve the knotty problem of overheating and burning your house down, something that is generally undesirable. If you wanted it as your main power supply there's a model that can store and discharge up to 7 kWh daily and costs $3000. Best of all it should last 10 years, which is approximately.
8 years longer than my laptop battery made it before it wouldn't hold a charge anymore. The trick to this longevity is how much power it outputs. It's only pumping out 2 kW continuously and peak output is 3.3 kW. The problem that then arises is some appliances will use more than that output. An electric clothes dryer could draw that much power on its own. So if you want dry clothes, I hope you weren't planning on using a microwave too. If you wanted to be not reliant on the grid at all, you'd probably need a few powerwalls.
To go with your solar roof panels. Depending on where you live, your power consumption can vary widely, but the average US home in 2011 used 940 kWh per month. A solar setup of that size would cost over $11,000, not including installation or taking tax credits into account. Then you'd need 5 Powerwalls to store all of that sunshine juice, so that's another 15 grand. It's an expensive prospect right now, but as the cost of batteries and solar panels continue to drop, individual homes that are independently powered could.
Become a great way to kick our fossil fuel habit. Inexpensive home batteries are looking like a promising innovation. They're not the only company innovating. Intel creates the breakthrough technologies that make amazing experiences possible. Having Intel inside makes for better experiences outside. Intel drives innovation with products like processors, wearables and IOT devices, and within data centers. In the PC and beyond. Going green sounds like a lot of effort. Is it really worth it Trace explains why yes, totally, it is, right here. Would you use the powerwall Would it be a supplement for your energy use or would you.
DIY Solar Panel System Cost
The total of the system and materials was $22K. I ended up spending about another $1,800 in permit fees and a structural engineer and $400 for an electrician, several hundred dollars for a guy to come help me out for the two afternoons he spent with me. Xcel Energy gave me $16,538 rebate. Fix cost based on the number of kilowatts you are installing and has nothing to do with how much you pay the permit office or the electrician. My final cost after rebate was $7,237. I started my research in solar probably about a year before I actually installed it went.
And got a couple of bids from some of the local solar people both from contractors that my friends have used as well as just searching the internet and while talking to one of the guys I find of developed a good feeling from him, and I asked the question Would it be possible to do some of the work myself and kind of learn along the way he said Sure I absolutely support the doityourselfer DIY so I said why don't you throw me bids, what it would cost just come home and have solar one day and what it would cost to have.
It done where I do some or all the work myself. And throw them both to me and I said let's try the second one. The guys name is Steve Cross from Sun Spot Solar. I gave him my electric bills and said this is how much I think I need to generate and he said I agree and lets do these types of panels 180 watts each, you will need some where around 19 to 22 we figured out 21 fit pretty well. So I went and got all the permit information from Golden, filled it out. He came by 12.
Hour one day he type all the Xcel application on the internet and I kind of ran the process and when I had a question I would just send him an email and he helped me out. I think in parallel we order the equipment he dropped off in my driveway. Then one of his installers came out and helped me for two afternoons and I pretty much myself put in the whole rack system on the roof and the installer came out and helped me kind of a two man job carrying the panels up, putting the panels down and bracketing them down.
Stanford Start.Home Solar Panels
We decided to go with thin film. We liked that it was a pretty new technology that's actually getting better and better. There's a lot of great things about it. First, it's a lot cheaper than monocrystalline and it's also uses a lot less material. It's just a thin sheet of glass then, then the semiconductor layer. And so we really like that about these panels. And with a onthegrid system, like our house, you're actually selling electricity back to the grid. And then the great thing about it is that you produce the.
Most PV energy, photovoltaic energy during the day, when the sun's out. And that's actually when you would pay the most for it from the electric company. And so you're selling it back at those critical peak demand times, reducing the overall load on the system. We're using a standing steamed sheet metal roof, and it has these ridges in it so that you can actually use these clip products and just attach the, the PV panels to the roof. So that really reduces the amount of time it takes to install these PVs.
Maryland Home Solar Power Vivint Solar Customer Review
My name's Caleb I'm from Maryland and I'm a Vivint Solar Customer. A guy in an orange shirt came over and told us all about solar panels. He told us about saving energy and money for people who don't have any money. about solar panels the sun beams on them to make power for us. The best part is my dad gets to save money for other stuff I've been learning about school and taking care of the earth we say we don't care the grass will grow back I don't even want.
Why Teslas Powerwall Battery Is Amazing
All of humanity just won a really important victory in our battle to lower the CO2 emissions that are causing climate change. Tesla CEO Elon Musk introduced the world to the Powerwall, a wallmounted battery for your house which aims to accelerate our transition to clean solar and windpower. Before the powerwall, there was no way to store the energy generated from the panels that capture sunlight on our roofs. So during the day they could give you the power you needed, but at night, you had to rely on the grid, which gets most of its.
Electricity from coal, natural gas, and nuclear reactors. There had been some early home batteries out there, but nothing that was nearly this affordable. But Tesla, which has built thousands of large, lithiumion battery packs for its growing electric car business, was able to produce a similar battery for buildings at a scale that dropped the production costs dramatically. The lowest capacity model will cost just $3,000. And this is the first generation of the productbefore Tesla's even completed building its massive new Gigafactory, or any real competitors have entered the market, events that will surely push the price down.
Even further, while increasing the energy storage capacity of the Powerwall. Here's how it works. When the sun is out, solar panels will power your house and charge the Powerwall at the same time. And when the sun goes down, this charged battery will kick in to meet most or all of your electricity needs until the sun comes back up again the next morning. This is gamechanging. More and more people will go completely offgrid. Every building whether it's a home, office, business, warehouse, factory they can all.
Install solar panels and some Powerwalls and instantly see their fossil fuelgenerated electricity needs drop significantly. Not every building will be able to go completely solarpowered, but most will get pretty close, especially as our appliances become more and more energy efficient. And it gets even better. The powerwall will be connected to the Internet and the rest of the energy grid. Here in Southern California, and most other heavily populated places, the electricity company charges us a lot more when we use electricity during peak timethat's in the afternoon and early evening when the temperatures are warmest and most of us are.
Home and still awake. The Tesla battery is smart, and knows when electricity is cheapest, so that's when it will draw from the grid to charge itself. And then, during peak time when you need electricity, the battery will power the house. Sometimes, you'll be able to sell back unused power to the utility company during peak time to even make a profit. It's basically going to make each individual building its own power station. Overnight, Tesla seems less a futuristic car company, and more like the man who inspired the company's name, a revolutionary electricity engineer named Nikola.

Power Your Entire Home Without Wires!
This episode of DNews is proudly brought to you by Subaru. BY TESLA WE'VE GOT IT! Wireless electricity might be coming to a home near you. y'know. Someday. Greetings programs, Trace here for DNews. In 1897, Nikola Tesla asexual genius and inventor extraordinaire wanted to QUOTE turn the whole world into a giant wireless dynamo. He was awarded a patent in 1907 for wireless electricity but then the Great War began and the whole thing was lost to history. Now, over a century later, researchers at MIT created wireless power transmission which.
Could realize his dream! Sort of. While Tesla was trying to power cities, this transmits wireless power around your house! Your phone, car, television, laptop, game console, controllers, remotes, toaster and every lightbulb in every frickin' lamp could all be powered by magnetic resonators. The Faraday Law of Induction describes how an electromagnet creates a magnetic field. When an electrified coil of wire is wrapped around a metal rod, the metal magnetizes. Similarly, when you pass a magnet THROUGH an unpowered coil of wire, the magnet creates electricity. Physics is awesome.
Researchers at MIT found a way to turn simple physics into a wireless way to transmit electricity using a similar technology to WiFi. By plugging in a resonator to the alternating current outlet in your wall, the device creates a magnetic oscillation. The magnetic field of the resonator is large enough to mingle with nearby coils installed in the walls and floors of your house and ultimately into every device and BOOM wireless power. One magnetic coil influences another and another all over the house. It's like the barking chain in.
101 Dalmatians! MIT spun off the technology into a funny named company called WiTricity. The system can already power televisions, cell phones and keep their special AA batteries fully charged all at the same time! To be honest, induction charging has been around for a while, as has wireless power transmission. Radio waves are wireless power, the pads you can buy to charge your cell phone, mouse or game controllers use wireless power, but this is a bit different. The ones we have now use nearfield induction and this blows it into a whole new proportion.
The problem with any of these systems, is the efficiency. Magnetic fields have to be relatively closeby to pick up other magnetic fields. The MIT researchers were able to power one 60 watt light bulb from 2 meters away but it was only 45 efficient. So they put in 133 watts to power a 60 watt bulb. Not awesome though according to the researchers, this system is 1 million times more efficient than the ones already on the market. and the CEO of WiTricity says it's 1,000 times more efficient than a battery!.
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.
